It is important to remember that reliable data is only collected when the user is wearing the device regularly and properly. When a user fails to wear the device or wears the device in a manner that would prohibit the collection of data \u2014 for example, wearing the device on the ankle instead of the wrist or wearing the device while pushing a shopping cart \u2014 the data would be inconsistent and therefore, fail to provide such an intimate knowledge of the wearer\u2019s life. Additionally, step counts can be false or misleading because the device will record less activity data when the activity requires less arm movement \u2014 like pushing a shopping cart or baby stroller.17<\/a> <\/span><\/sup><\/p>\r\n\r\n\r\n

All you need is a device and application to connect to the multitude of computers, servers, and data storage systems that create the cloud<\/q> of computing services. After the device syncs the activity data to the cloud, users can view the data in their online Fitbit profiles where they can scrutinize their progress and improvements (or failures), plan and strategize their exercise routines, and examine their health statistics and data. With this user-friendly technology and continued societal concern of staying healthy, Fitbit wearables are only becoming more popular.19<\/a> <\/span> 19 <\/span>See John Divine, Fitbit Does It Again; Beats Expectations for Earnings, Revenue<\/cite><\/a>, U.S. News<\/span> (Aug. 2, 2016, 5:16 PM).<\/span><\/sup><\/p>\r\n\r\n

\r\n<\/a>B. The growing demand for wearable technology\r\n<\/h3>\r\n\r\n

<\/a>From smartwatches and smart glasses to fitness trackers and health monitors, the possibilities are limitless for innovations in the wearable technology industry.20<\/a> <\/span> 20 <\/span>See generally Margaret Rhodes, A Wearable Gadget Implanted in Your Hand Isn\u2019t as Freaky as You\u2019d Think<\/cite><\/a>, Wired<\/span> (Oct. 20, 2014, 6:30 AM). <\/span><\/sup> The most popular wearables thus far are the devices that fall into the category of fitness trackers, but statistics prove that wearable devices as an entire group are not as popular as many may believe.21<\/a> <\/span> 21 <\/span>The Wear, Why, and How<\/cite><\/a>, The Economist<\/span> (Mar. 14, 2015).<\/span><\/sup> This may contribute to why there have been so few cases to discuss the issue of using wearable data in court, but it does not necessarily diminish the need for clarity in the standards and requirements for admitting wearable technology data into evidence.22<\/a> <\/span> 22 <\/span>See Steven W. Teppler, Testable Reliability: A Modernized Approach to ESI Admissibility<\/cite><\/a>, 12 Ave Maria L.

\r\n<\/a>III. The Untapped Potential of Using Fitbit Data As Evidence\r\n<\/h2>\r\n\r\n

<\/a>Recognizing the value of ESI evidence, several courts have begun to allow data from other types of electronic devices to be admitted as evidence during litigation.26<\/a> <\/span> 26 <\/span>See United States v. Safavian<\/i>, 435 F. Supp. 2d 36<\/a>, 36 (D.D.C. 2006) (allowing emails as evidence); State v. Dunn<\/i>, 7 S.W.3d 427<\/a>, 427 (Mo. Ct. App. 1999).<\/span><\/sup> For instance, electronic discovery has been used in numerous cases to obtain anything from text messages stored on mobile devices, to the Internet search history stored on the hard drive of a computer.27<\/a> <\/span> 27 <\/span>Michael Arnold & Dennis R. Kiker, Big Data Collection Problem of Little Mobile Devices<\/cite><\/a>, 21 Rich. J.L. & Tech<\/span>. 10, 10-31 (2015).<\/span><\/sup> Under the current Federal Rules of Evidence, admitting ESI collected from portable devices and computers as evidence does not require much more than the admission of standard evidence. However, despite the fact that the legal system has seen a continued increase in the use of digital data in cases, courts have been hesitant to address the admissibility of evidence collected and stored specifically on wearable devices.28<\/a> <\/span> 28 <\/span>Samuel Gibbs, Court Sets Legal Precedent With Evidence From Fitbit Health Tracker<\/cite><\/a>, The Guardian<\/span> (Nov. 18, 2014, 11:03 EST).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>Unlike in the past when the discovery tools available to uncover relevant evidence were limited to methods such as plaintiff testimony, expert testimony, medical records, and surveillance, wearable devices, like Fitbits, will be able to provide attorneys with a new source of evidence in the form of hard data.29<\/a> <\/span> 29 <\/span>Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl.

\r\n<\/a>A. Glimpses of wearable devices in the justice system \r\n<\/h3>\r\n\r\n

<\/a>The first known case in the United States to use data from a wearable device began when the police in Lancaster County, Pennsylvania, collected information from a Fitbit to help determine that Jeannie Risley fabricated a rape report.32<\/a> <\/span> 32 <\/span>Valerie Waltz, Police: Florida Woman Fabricated Rape Report in Lancaster County<\/cite><\/a>, FOX43 (June 19, 2015, 11:59 AM).<\/span><\/sup> Risley called 911 and reported to the police that she was sleeping when she woke up to find her attacker sexually assaulting her. However, further investigation revealed evidence directly contradicting her claim.33<\/a> <\/span> 33 <\/span>Brett Hambright, Police: Fitbit Reveals Fake Report<\/cite><\/a>, LancasterOnline<\/span> (June 19, 2015).<\/span><\/sup> During the investigation, the police found Risley\u2019s Fitbit on the floor and when they downloaded its activity, the device became a witness against her.<\/q>34<\/a> <\/span> 34 <\/span>Kashmir Hill, Fitbit Data Just Undermined a Woman\u2019s Rape Claim<\/cite><\/a>, Fusion<\/span> (June 29, 2015, 2:57 PM).<\/span><\/sup> The activity data collected by the device revealed that she was actually awake and moving around the premises at the time she claimed she was attacked.35<\/a> <\/span> 35 <\/span>Brett Hambright, Police: Fitbit Reveals Fake Report<\/cite><\/a>, LancasterOnline<\/span> (June 19, 2015).<\/span><\/sup> In combination with the other evidence poking holes in Risley\u2019s story, such as the lack of footprints in the snow outside the home and the missing signs of an intrusion, her Fitbit data led the police to dismiss her assault claim. As a result, Risley was charged with false reports to law enforcement, false alarms to public safety, and tampering with evidence for allegedly overturning furniture and placing a knife to make it appear she had been raped [at knifepoint].<\/q> Unfortunately, there is limited information on her physical appearance and the medical reports from the time that the event took place.36<\/a> <\/span> 36 <\/span>Myles Snyder, Police: Woman\u2019s Fitness Watch Disproved Rape Report<\/cite><\/a>, ABC27.com (June 19, 2015, 2:28 PM).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>The Lancaster case may have been the first known use of this type of data in the United States legal system, but the first case to ever use Fitbit data in a courtroom was a personal injury case that took place in Canada.37<\/a> <\/span> 37 <\/span>Alexander Howard, How Data From Wearable Tech Can Be Used Against You in a Court of Law<\/cite><\/a>, The Huffington Post<\/span> (July 3, 2015, 12:59 PM EDT).<\/span><\/sup> In this case, the plaintiff, a former personal trainer, was injured in an accident four years earlier, when Fitbit was not yet available to the public.38<\/a> <\/span> 38 <\/span>Parmy Olson, Fitbit Data Now Being Used in the Courtroom<\/cite><\/a>, Forbes<\/span> (Nov. 16, 2014, 4:10 PM).<\/span><\/sup> Unfortunately, this meant that the plaintiff would be unable to show her activity data from before the accident occurred, but her attorneys still believed this would be enough.39<\/a> <\/span> 39 <\/span>Karla Grossenbacher, Wearables<\/q> In Court: How Your Electronic Data Becomes Evidence<\/cite><\/a>, Law360<\/span> (July 13, 2015); Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl.

<\/a>These two cases are just the beginning of legal authorities and parties tapping into the vast amounts of information gathered by wearable devices to supplement or defend their cases.44<\/a> <\/span> 44 <\/span>Samuel Gibbs, Court Sets Legal Precedent With Evidence From Fitbit Health Tracker<\/cite><\/a>, The Guardian<\/span> (Nov. 18, 2014, 11:03 EST). <\/span><\/sup><\/p>\r\n\r\n

\r\n<\/a>B. Supplementing or replacing witness testimony \r\n<\/h3>\r\n\r\n

<\/a>Wearable data has unlimited potential in the legal context to help resolve some of the weaknesses that plague current forms of evidence. One of the most prevalent weaknesses stems from concerns about the reliability and credibility of witnesses. Using Fitbit data as an additional source of evidence could help eliminate the concerns about the fallibility of human memory, biases, and intentional deceptions that undermine witness testimony reliability.<\/p>\r\n\r\n\r\n

<\/a>Courts are aware of the flaws that abound in witness testimony and are particularly concerned with the fallibility of the human memory. After studying human memory capabilities, psychologist Elizabeth Lofus stated<\/p>\r\n\r\n

\r\nEarly on . . . the observer must decide to which aspects of the visual stimulus he should attend. Our visual environment typically contains a vast amount of information, and the proportion of information that is actually perceived is very small . . . . Once the information associated with an event has been encoded or stored in memory, some of it may remain there unchanged while some may not. Many things can happen to a witness during this crucial retention stage.45<\/a> <\/span> 45 <\/span>Elizabeth F. Loftus, Eyewitness Testimony<\/a><\/span> 21 (1st ed. 1979). <\/span><\/sup>\r\n<\/blockquote>\r\n\r\n

<\/a>Lofus was also not the first to recognize the inherent faults in human memories. In fact, the United States Supreme Court has even found the issue so prominent in litigation that it included dicta on the subject within several different opinions.46<\/a> <\/span> 46 <\/span>See, e.g., United States v. Wade<\/i>, 388 U.S. 218<\/a>, 235 (1967); Manson v. Brathwaite<\/i>, 432 U.S. 98<\/a>, 119 (1977).<\/span><\/sup> For instance, Justice Brennan addressed the imperfections of human memories in the context of mistaken eyewitness testimony by explaining that it is most likely attributed to the inherent dangers of eyewitness testimony and the suggestibility intrinsic to the pretrial process.47<\/a> <\/span> 47 <\/span>See, e.g., United States v. Wade<\/i>, 388 U.S. 218<\/a>, 235 (1967).<\/span><\/sup> Unfortunately, there are a large number of cases involving mistaken identifications by witnesses, based on the proverbial untrustworthiness that characterizes eyewitness testimony, to support Justice Brennan\u2019s argument.48<\/a> <\/span> 48 <\/span>Fredric D. Woocher, Did Your Eyes Deceive You? Expert Psychological Testimony on the Unreliability of Eyewitness Identification<\/cite><\/a>, 29 Stan. L. Rev<\/span>. 969, 970 (1977) (citing F. Frankfurter, The Case of Sacco and Vanzetti <\/span>(1927)).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>This problem also exists in other areas of witness testimony, including testimony given by experts. [Courts] understand that doctors and other witnesses have expertise, but they [are not] all-knowing beings.<\/q>49<\/a> <\/span> 49 <\/span>Kate Crawford, When Fitbit Is the Expert Witness<\/cite><\/a>, The Atlantic<\/span> (Nov. 19, 2014).<\/span><\/sup> As a result, courts use cross-examination as a safeguard<\/q> against inaccuracies and are tasked with determining the reliability of the evidence, in light of the possibility that the witness\u2019s memory is inherently unreliable.50<\/a> <\/span> 50 <\/span>United States v. Wade<\/i>, 388 U.S. 218<\/a>, 235 (1967).<\/span><\/sup> The pervasiveness of such faulty memories has been the subject of both legal and medical studies for decades and the resulting conclusion is that human memory is flawed because: (1) an observer cannot possibly take in all of the information available in a scene; and (2) an observer\u2019s memory may shift over time, including what may naturally be forgotten and what may be reconstructed from suggestive procedures.<\/q>51<\/a> <\/span> 51 <\/span>Kristin Bergman, Cyborgs in the Courtroom: The Use of Google Glass Recordings in Litigation<\/cite><\/a>, 20 Rich. J.L. & Tech.<\/span> 11 (2014) (citing Elizabeth F. Loftus, Eyewitness Testimony<\/span> (1st ed. 1979)).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>Additional concerns about witness credibility involve both biases and intentional deceptions. In studies concerning the affect of biases on witnesses, psychologists have concluded that biases permeate individual\u2019s decision-making so much that they impact everything from distance perception to choosing a seat on a plane.52<\/a> <\/span> 52 <\/span>Anjanette H. Raymond & Scott J. Shackelford, JD, PhD, Jury Glasses: Wearable Technology and Its Role in Crowdsourcing Justice<\/cite><\/a>, 17 Cardozo J. Conflict Resol<\/span>. 115, 136 n.95 (2015).<\/span><\/sup> This is caused by the personal needs and motives of the observer [distorting their] perception.<\/q> For example, victims may unconsciously alter their memories of their attacker\u2019s physical appearance by including physical characteristics that the victim associates with the personality traits typified by the criminal\u2019s behavior.<\/q>53<\/a> <\/span> 53 <\/span>Fredric D. Woocher, Did Your Eyes Deceive You? Expert Psychological Testimony on the Unreliability of Eyewitness Identification<\/cite><\/a>, 29 Stan. L. Rev<\/span>. 969, 981 (1977).<\/span><\/sup> This is not done in an attempt to lie or to deceive the court, rather it is an unconscious phenomenon caused by the victim\u2019s beliefs and prior experiences. Though it occurs less frequently than the other flaws of witness testimony, there are also instances where witnesses consciously lie in an attempt to deceive the justice system.<\/p>\r\n\r\n\r\n

<\/a>However, technology is on the verge of making lying much more difficult to get away with. In fact, the full scope of how our increasingly networked and documented lives can catch deceptions can be hard to fathom.<\/q> With the accumulation of data from wearable devices comes a better way to determine the credibility of witness testimony. To utilize technology in this manner, courts would need to employ the use of wearable data as supplemental evidence as a comparison to what someone is actually testifying.54<\/a> <\/span> 54 <\/span>Andrea Peterson, How Technology Could Kill the Art of Lying<\/cite><\/a>, The Washington Post<\/span> (July 8, 2015).<\/span><\/sup> Of course, this is in circumstances limited to the type of data collected by the specific device worn by the witness \u2014 for instance, Fitbit data would most likely not be able to disprove inaccurate eyewitness identification. However, Fitbit data could be useful in proving that a witness lied about their location on the day of the crime. A great example of this potential use of wearable data is the Lancaster case involving Risley\u2019s false rape report. The use of the Fitbit data to disprove Risley\u2019s false rape report, eradicated Risley\u2019s chance of getting away with her lies to the police.55<\/a> <\/span> 55 <\/span>See, e.g., Scott Greenfield, But for Fitbit: A Rape That Never Happened<\/cite><\/a>, Mimesis Law<\/span> (June 30, 2015).<\/span><\/sup> Using wearable technology data as evidence in this manner helps eliminate the conscious or unconscious ability to lie as a witness, but fails to completely remove the opportunity to be deceitful due to the possibility of the information being faulty or misleading.<\/p>\r\n\r\n\r\n

<\/a>These weaknesses, intrinsic to witness reliability, have significantly impacted numerous cases throughout the entire history of the justice system. In an attempt to solve the issues of fallibility of human memory and potential biases, courts could allow data from Fitbits and other wearable devices to be used as supplemental evidence to witness testimony. A great example of this potential use is shown by the personal injury case from Canada \u2014 in which the plaintiff supplemented her own testimony with activity data from her Fitbit, to help prove that her accident had caused her injuries, which limited her ability to exercise, and therefore helped eliminate doubts shrouding her claims that potentially entitled her to compensation.56<\/a> <\/span> 56 <\/span>See generally Keith Lee, The Newest Field of E-Discovery: You<\/cite><\/a>, Above the Law<\/span> (Nov. 20, 2014, 3:04 PM).<\/span><\/sup> Using wearable device data to supplement a plaintiff\u2019s testimony and replace the testimony typically provided by an expert witness eliminates the fallacies that plague witness testimony, because the wearable device is a machine that cannot generate biased, unconscious, or intentionally deceitful results. Additionally, wearable device-generated data cannot be considered hearsay for the purpose of admitting it as evidence since hearsay does not include statements made by animals of machine-generated assertions.57<\/a> <\/span> 57 <\/span>Fed. R. Evid<\/span>. 801<\/a>.<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>There are few tested examples of the potential uses for wearable data as evidence, but as the devices grow in popularity, it is likely that Fitbits, and other wearable technology, will be used as evidence for the purposes of self-incrimination, impeaching the witness, or bolstering the plaintiff\u2019s case.<\/p>\r\n\r\n

\r\n<\/a>C. Predicting wearable technology\u2019s potential in litigation\r\n<\/h3>\r\n\r\n

<\/a>There has been a tremendous amount of speculation about the myriad of cases in which wearable technology would be useful in supplementing or defending a claim. Not only could this type of data be useful in personal injury cases and criminal cases, as discussed above, but there is also potential for this data to be relevant in several other legal scenarios including: (1) criminal cases in which one would need an alibi; (2) civil cases like traffic violations, car accidents, or even divorces in which heart rate data and location could prove an extramarital affair; (3) claims of self-defense in which heart rate and activity data could suggest they were in a dangerous situation; and (4) workers\u2019 compensation claims, particularly when an employee is injured on the job while wearing a device that tracks location and health data.58<\/a> <\/span> 58 <\/span>See generally Christina Bonnington, Data From Out Wearables Is Now Courtroom Fodder<\/cite><\/a>, Wired<\/span> (Dec. 12, 2014, 6:30 AM).<\/span><\/sup> Though many believe that wearables could be a gold mine of potentially relevant ESI,<\/q>59<\/a> <\/span> 59 <\/span>Neda Shakoori, Wearable Technology: A Perfect Fit For Litigation<\/cite><\/a>, Mcmanislaw.com<\/span> (Aug. 21, 2014).<\/span><\/sup> it is difficult to predict the full potential of the hoarding of digital data in the legal realm.<\/p>\r\n\r\n

\r\n<\/a>IV. Evidentiary Challenges and the Chaos of Wearables\r\n<\/h2>\r\n\r\n

<\/a>There are always risks with technology innovations and wearable technology is no exception to that rule. While there are many potential benefits to admitting data from wearable devices as evidence in court, there are several challenges (many evidentiary) that will make that process extremely difficult.<\/p>\r\n\r\n\r\n

<\/a>Technology is always changing and growing to appeal to mass markets. As a result, courts are struggling to keep the discovery-net wide enough to encompass information stored on wearable smart devices as the technological industry constantly evolves. There are a number of ways in which wearables could encumber the litigation process, but this Article focuses primarily on how to determine the relevance, reliability, and probativity of the data stored on wearable devices for use as evidence in court. Other problems not fully discussed in this Article include the identification of potential ESI becoming more difficult because most users will be unaware that the data stored and collected by wearable tech is discoverable. Preservation is also becoming more difficult because most users will not know to preserve the information, and collection of the data is becoming more complicated because most wearables send the ESI to the cloud.60<\/a> <\/span> 60 <\/span>Maureen O\u2019Neill, E-Discovery and the Internet of Things<\/cite><\/a>, DiscoverReady<\/span> (Nov. 14, 2014). <\/span><\/sup> Another issue that seems to arise from using wearable device data, as evidence, is that opposing parties will try to compel that the information be turned over by the device wearer as part of routine discovery in personal injury cases.<\/q>61<\/a> <\/span> 61 <\/span>Steven M. Sweat, Could Apple Watch Data Prove Your Personal Injury Case?<\/cite><\/a>, Victimslawyer.com<\/span> (May 4, 2015).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>Through the years, the courts have had to determine the best ways to deal with the immeasurable amount of information found through electronic discovery, the privacy concerns associated with that process, the preservation of such volatile data, and the production of the ESI. In response to the growing need for ESI to be admissible as evidence, changes were made to Rule 34 of the Federal Rules of Civil Procedure.62<\/a> <\/span> 62 <\/span>See Michael Arnold & Dennis R. Kiker, Big Data Collection Problem of Little Mobile Devices<\/cite><\/a>, 21 Rich. J.L. & Tech<\/span>. 10, 10-31 (2015).<\/span><\/sup> These changes addressed some of the issues courts were encountering when trying to request electronic discovery of digital data. As a result of these efforts, Rule 34 now states that a party may request, within the scope of Rule 26(b), any other party to produce any designated documents or electronically stored information \u2014 including writings drawings, graphs, charts, photographs, sound recordings, images, and other data or data compilations \u2014 stored in any medium from which information can be obtained either directly or, if necessary, after translation by the responding party into a reasonably usable form.<\/q>63<\/a> <\/span> 63 <\/span>Fed. R. Civ. P. 34<\/a>(a)(1)(A). <\/span><\/sup> This effectively settled the dispute over whether ESI could be considered a document<\/q> under the rules. However, numerous issues still plague the discovery and use of ESI, particularly now that ESI is also being collected from wearables and used as evidence.64<\/a> <\/span> 64 <\/span>Margaret Littman, Data From Wearable Devices Is Being Eyed as Evidence in the Courtroom<\/cite><\/a>, A.B.A. J.<\/span> (Apr. 1, 2015, 4:00 AM CDT).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>The biggest challenges facing the use of wearable data as evidence are the reliability flaws of the devices themselves and the evidentiary hurdles that are likely to keep courts from admitting the data as evidence.<\/p>\r\n\r\n

\r\n<\/a>A. The chaos of wearables\r\n<\/h3>\r\n\r\n

<\/a>To provide a comprehensive understanding of the concerns and challenges arising from the use of wearable technology data as evidence, it is vital to consider the inherent flaws of the current wearables on the market.65<\/a> <\/span> 65 <\/span>See generally Kate Crawford, When Fitbit Is the Expert Witness<\/cite><\/a>, The Atlantic<\/span> (Nov. 19, 2014). <\/span><\/sup><\/p>\r\n\r\n

\r\n<\/a>1. Reliability Concerns Abound <\/i>\r\n<\/h4>\r\n\r\n

<\/a>The wearable devices on the market continue to become more sophisticated, with better features and functionality. But until the industry addresses the inherent lack of reliability associated with wearables, it will be difficult to use the data they collect as evidence in court. Even if the industry addresses the lack of reliability, additional issues of relevancy, accessibility, privacy, collecting\/processing and costs will prevent a significant number of cases from using this data as evidence.66<\/a> <\/span> 66 <\/span>Neda Shakoori, Wearables: Your Next Trial Witness?<\/cite><\/a>, Daily J.<\/span> (S.F., Cal.) (Dec. 10, 2014).<\/span><\/sup> The data from these devices is unreliable for several reasons including, but not limited to: (1) the ability to be misused (users can remove the device at any time, users can self-manipulate the data, people other than the owner could be using the device, some of the devices could register moving your arms as steps,<\/q> and even animals could wear the devices and log activity data)67<\/a> <\/span> 67 <\/span>Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl. Young Law. Committee (DRI Young Lawyers Committee<\/span>) no. 5 (June 4, 2015). <\/span><\/sup>, (2) the ability for the data to be misinterpreted (due to the potential use of third-party analytics companies instead of the raw data), and (3) the large discrepancies between the different wearables on the market.68<\/a> <\/span> 68 <\/span>Kate Crawford, When Fitbit Is the Expert Witness<\/cite><\/a>, The Atlantic<\/span> (Nov. 19, 2014).<\/span><\/sup> This will make it incredibly difficult for courts and analytics companies to standardize the admissibility of wearable data.<\/p>\r\n\r\n\r\n

<\/a>For example, when Fitbit is monitoring a user\u2019s heart rate, a large variety of factors could affect the data collected on the device. Another example includes the accuracy of the GPS data collected on Fitbits. The GPS in Fitbits requires a direct path to the satellite it is using to receive and transmit radio transmissions. If the signal is being blocked \u2014 either because you\u2019re underground, near many tall buildings, or as a result of atmospheric effects \u2014 GPS will not work. Thus, whereas GPS gives you a more accurate measure of distance than step counting alone, the actual accuracy depends on both your environment and the weather.<\/q>69<\/a> <\/span> 69 <\/span>How Accurate is GPS?<\/cite><\/a>, Fitbit.com<\/span>.<\/span><\/sup><\/p>\r\n\r\n

\r\n<\/a>2. Problems that May Arise <\/i>\r\n<\/h4>\r\n\r\n

<\/a>An example of why the misuse of the device could be a problem can be seen in the Lancaster case. During the police investigation, the woman said her Fitbit was lost during the altercation, but the device was then found and the data on it used against her.70<\/a> <\/span> 70 <\/span>Brett Hambright, Police: Fitbit Reveals Fake Report<\/cite><\/a>, LancasterOnline<\/span> (June 19, 2015).<\/span><\/sup> But what if someone else took the device and wore it or put it on an animal? What if a plaintiff\u2019s wearable device records less activity post-accident? Would that be evidence that the plaintiff sustained injuries during the accident that affect their ability to exercise, or just reflect that they either wore the device less or exercised less post-accident to manipulate the data collected?<\/p>\r\n\r\n\r\n

<\/a>These questions do not have complete answers because the technology is still advancing to recognize the different circumstances apparent in each of these hypothetical situations. As Neda Shakooi explains, on some devices you can binge-watch Orange Is the New Black while seated and, if you wave your arms, your device may log it as physical activity. Even when the devices work as intended, people forget to charge, sync, or even wear them.<\/q>71<\/a> <\/span> 71 <\/span>Margaret Littman, Data From Data from Wearable Devices Is Being Eyed as Evidence in the Courtroom<\/cite><\/a>, A.B.A. J. (Apr. 1, 2015, 4:00 AM CDT).<\/span><\/sup> Additionally, another major issue is that the features and functionality of these wearables varies greatly between brands and devices,72<\/a> <\/span> 72 <\/span>Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl. Young Law. Committee (DRI Young Lawyers Committee)<\/span> No.<\/span> 5 (June 4, 2015). See also How Accurate are Fitbit Trackers?<\/cite><\/a>, Fitbit.com<\/span>; see also Nicole L. Black, Wearable Tech Data as Evidence in the Courtroom<\/cite><\/a>, LLRX.com<\/span> (Sept. 23, 2015).<\/span><\/sup> and as such, the devices are too inconsistent amongst themselves for analytics companies to attempt and standardize the process of interpreting data stored on them.73<\/a> <\/span> 73 <\/span>Kate Crawford, When Fitbit Is the Expert Witness<\/cite><\/a>, The Atlantic<\/span> (Nov. 19, 2014).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>Even if you can determine that all of those reliability concerns have been rectified, the collection of ESI on wearable technology will still be an extremely difficult task that will potentially require these third-party analytics companies to interpret the data and present it in a form that courts will be capable of understanding.74<\/a> <\/span> 74 <\/span>See generally Neda Shakoori, Wearables: Your Next Trial Witness?<\/cite><\/a>, Daily J. (S.F., Cal.)<\/span> (Dec. 10, 2014).<\/span><\/sup> This challenge involves operational and evidentiary issues because these types of technology devices use the cloud computing systems to store the data they collect. At a recent symposium one discussion focused on the practical challenges to obtain and use Fitbit data in litigation with one participant commenting, [b]ut then you [try and] get it out and you just sort of say, What can I even do with it? Because I can\u2019t present it at trial. It\u2019s completely unworkable; there\u2019s some difficulty even making sense of it.<\/q><\/q>75<\/a> <\/span> 75 <\/span>James R. Silkenat, Practicing Law in the Age of Surveillance and Hackers \u2014 An Exploration of Privacy and Data Security<\/cite><\/a>, 38 Am. J. Trial Advoc.<\/span> 575, 576 (2015).<\/span><\/sup> Finally, the cost of obtaining the data from the provider and paying the third-party analytics company, that will interpret the data, will inhibit a large number of parties from using this type of evidence that could potentially be very useful in their cases.76<\/a> <\/span> 76 <\/span>Neda Shakoori, Wearables: Your Next Trial Witness?<\/cite><\/a>, Daily J. (S.F., Cal.)<\/span> (Dec. 10, 2014).<\/span><\/sup> All of these examples only scratch the surface of the potential reliability concerns that will persist when parties rely on Fitbit and other wearable device data as evidence.<\/p>\r\n\r\n

\r\n<\/a>B. Problems with ESI involving the Federal Rules of Evidence\r\n<\/h3>\r\n\r\n

<\/a>The current cases using Fitbit data should encourage the legal community to determine the manner and timing in which parties should be expected to disclose their wearable device data, regardless of whether it is a Fitbit or any other brand of wearable technology.77<\/a> <\/span> 77 <\/span>Alexander Howard, How Data From Wearable Tech Can Be Used Against You in a Court of Law<\/cite><\/a>, The Huffington Post<\/span> (July 3, 2015, 12:59 PM EDT).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>To introduce wearable technology data as evidence, the court must consider a number of the Federal Rules of Evidence that have been previously used to admit other forms of ESI. Judge Grimm\u2019s opinion in Lorraine v. Markel American Insurance Co.<\/i> for the United States District Court for the District of Maryland discussed the evidentiary rules analysis required for assessing the admissibility of ESI, and set forth a comprehensive guide for admitting ESI as evidence.78<\/a> <\/span> 78 <\/span>See generally Lorraine v. Markel Am. Ins. Co.<\/i>, 241 F.R.D. 534<\/a>, 538 (D. Md. 2007).<\/span><\/sup> The Lorraine<\/i> model begins with determining the relevance of the data and ends with balancing the probativity of the data with the danger of unfair prejudice.<\/p>\r\n\r\n\r\n

<\/a>The Lorraine<\/i> model suggests:<\/p>\r\n\r\n

\r\nWhenever ESI is offered as evidence, either at trial or in summary judgment, the following evidence rules must be considered: (1) is the ESI relevant as determined by Rule 401 (does it have any tendency to make some fact that is of consequence to the litigation more or less probable than it otherwise would be); (2) if relevant under 401, is it authentic as required by Rule 901(a) (can the proponent show that the ESI is what it purports to be); (3) if the ESI is offered for its substantive truth, is it hearsay as defined by Rule 801, and if so, is it covered by an applicable exception (Rules 803, 804 and 807); (4) is the form of the ESI that is being offered as evidence an original or duplicate under the original writing rule, of [sic] if not, is there admissible secondary evidence to prove the content of the ESI (Rules 1001-1008); and (5) is the probative value of the ESI substantially outweighed by the danger of unfair prejudice or one of the other factors identified by Rule 403, such that it should be excluded despite its relevance. Preliminarily, the process by which the admissibility of ESI is determined is governed by Rule 104, which addresses the relationship between the judge and the jury with regard to preliminary fact finding associated with the admissibility of evidence. Because Rule 104 governs the very process of determining admissibility of ESI, it must be considered first.79<\/a> <\/span> 79 <\/span>See generally Lorraine v. Markel Am. Ins. Co.<\/i>, 241 F.R.D. 534<\/a>, 538 (D. Md. 2007).<\/span><\/sup>\r\n<\/blockquote>\r\n\r\n

<\/a>Within Lorraine<\/i>\u2019s guide to determine if the data is admissible, the proponent of the ESI evidence must first determine the relevance of the data under Rule 401. Under this rule, information is determined to be relevant for the court\u2019s purposes if: (a) it has any tendency to make a fact more or less probable than it would be without the evidence; and (b) the fact is of consequence in determining the action.80<\/a> <\/span> 80 <\/span>Fed. R. Evid.<\/span> 401<\/a>.<\/span><\/sup> The vast amount of data collected on wearable devices could make it difficult for the parties and the courts to limit the scope of the e-discovery to just the information that makes a fact more probable or is important in determining the action. As an example, an arson investigator could not care less that you ran 5 miles on the date of the fire, but would be very interested that your running app[lication] mapped out your entire route, which happened to go right by the site of the blaze.<\/q>81<\/a> <\/span> 81 <\/span>Sharon D. Nelson, John W. Simek & Thomas L. Mighell, <\/span>What the Internet of Everything Means for Lawyers: Evidence, Privacy and Data Security Implications<\/cite><\/a>, American Law Institute<\/span>(Feb. 9, 2015).<\/span><\/sup> Both pieces of information are intertwined within the wearable device, and therefore it would be difficult to limit the collection of evidence to just the one bit of information being sought as evidence, in this example the user\u2019s location, without including other data that is not relevant and not admissible evidence.<\/p>\r\n\r\n\r\n

<\/a>Though determining the relevancy is an important step in the evidentiary process, it is more important to determine the authenticity of the information and the probative value of the data. The authentication process for evidence focuses on three key elements required to prove the information is relevant to the case; these elements include legitimacy, accuracy, and the relation to the parties.82<\/a> <\/span> 82 <\/span>Christina Bonnington, Data From Out Wearables Is Now Courtroom Fodder<\/cite><\/a>, Wired<\/span> (Dec. 12, 2014, 6:30 AM).<\/span><\/sup> This is required under Rule 901(a), which states that the proponent of the evidence must satisfy the requirement of authenticating the evidence by producing evidence that could support a determination that the evidence is in fact what the proponent claims it to be. This requirement can be satisfied with a witness testifying that the item is what the proponent claims it is, as long as they have knowledge of the item, or with other evidence that describes the process and shows that the item generates reliable conclusions. Authentication can also be done with a comparison to other authenticated items under Rule 901(b)(3).83<\/a> <\/span> 83 <\/span>Fed. R. Evid. <\/span>901<\/a>(a), (b)(1), (b)(3), (b)(9). <\/span><\/sup> For example, emails can be authenticated by other emails already admitted into evidence, even when there is no identifying information included on the email because the email in evidence has the same screen name or characteristics.84<\/a> <\/span> 84 <\/span>Sheldon M. Finkelstein & Evelyn R. Storch, Admissibility of Electronically Stored Information: It\u2019s Still the Same Old Story<\/cite><\/a>, 23 J. Am. Acad. Matrim. Law<\/span>. 45, 48 (2010).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>As in the case of wearable devices, it will most likely be necessary to have the wearer of the device testify for purposes of authentication.85<\/a> <\/span> 85 <\/span>Fed. R. Evid. <\/span>901<\/a>(b)(1).<\/span><\/sup> And although there is a risk of manipulation of the data, the possibility of alteration does not directly eliminate the potential use of the data as evidence. Rather, the proponent simply has to present a reason for the jury to believe that the evidence is what they say it is. A potential downfall for plaintiffs bringing in such evidence is that they are later subject to review on cross-examination and this opens up the door for the opposing party to prove to the jury that the evidence is in fact not what the plaintiff would like you to think it is, or to impeach the witness.86<\/a> <\/span> 86 <\/span>Jill Schachner Chanen, What Everyone Is Wearing<\/cite><\/a>, A.B.A. J. 12, (Apr. 2015).<\/span><\/sup> When using wearable data that has been analyzed by a company like Vivametrica, the proponent would also need to authenticate the process used to produce the data and prove that the process leads to accurate findings.87<\/a> <\/span> 87 <\/span>Fed. R. Evid. <\/span>901<\/a>(b)(9).<\/span><\/sup> This too could be accomplished by having an expert witness from the company take the stand and testify to the authenticity of the analytical process. However, this expert testimony will be subject to the admissibility standards established by Daubert<\/i> and Rule 702.<\/p>\r\n\r\n\r\n

<\/a>In addition to authenticating the data, it is vital to determine the probative value of the data under Rule 403 before admitting the information as evidence. Rule 403 states that the court may exclude relevant evidence if its probative value is substantially outweighed by a danger of one or more of the following: unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence.<\/q>88<\/a> <\/span> 88 <\/span>Fed. R. Evid. <\/span>403<\/a>.<\/span><\/sup> Courts will be particularly concerned with the potential for unfair prejudice in circumstances when the court is concerned as to the reliability or accuracy of the information that is contained within the electronic evidence.<\/q>89<\/a> <\/span> 89 <\/span>Lorraine v. Markel Am. Ins. Co.<\/i>, 241 F.R.D. 534<\/a>, 538 (D. Md. 2007) (citing St. Clair v. Johnny\u2019s Oyster and Shrimp Inc<\/i>., 76 F. Supp. 2d 773, 773 (S.D. Tex. 1999)).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>Due to the unreliable nature of the wearable technology, it seems most likely that courts would decide that the data could prejudice the jury and therefore, should be deemed not admissible in evidence. For example, lie detector tests have been proven to be inherently unreliable technology and have been continuously banned from being used as evidence in the courtroom for fear that it could result in unfair prejudice and bias. For years, courts were also hesitant to admit emails and x-ray machine scans into evidence, but as the technology became more popular and better understood throughout society, parties were required to meet lesser standards to authenticate these items for use as evidence.90<\/a> <\/span> 90 <\/span>Lorraine v. Markel Am. Ins. Co.<\/i>, 241 F.R.D. 534<\/a>, 538 (D. Md. 2007).<\/span><\/sup><\/p>\r\n\r\n\r\n

<\/a>However, the use of wearable technology is not as prevalent in society as email and x-ray machines, and as such, the general population does not yet fully comprehend how they function. This presents a problem for the jury, because if they do not understand how the technology works, and they fail to understand the potential for unreliable data produced by these devices, it could result in an unfair bias. Though an argument exists that the use of wearable data could be used to bolster the party\u2019s case, it is more likely that courts will find it to result in a major bias and will find it inadmissible based on its unreliable nature.<\/p>\r\n\r\n\r\n

<\/a>To determine if wearable data can be used as evidence, it is also important to establish that the device is good science and reliable under Rule 702.91<\/a> <\/span> 91 <\/span>Fed. R. Evid. 702<\/a>. <\/span><\/sup> This is the most detrimental evidentiary hurdle that will need to be overcome and involves a combination of requirements set out by Rule 702 and Daubert<\/i>.92<\/a> <\/span> 92 <\/span>Daubert v. Merrell Dow Pharmaceuticals, Inc.<\/i>, 509 U.S. 579<\/a>, 590-95 (1993).<\/span><\/sup> Under Daubert<\/i>, expert testimony is admissible under Rule 702 when it (1) helps the trier of fact better comprehend the evidence or determine facts at issue, (2) is based on sufficient facts or data,<\/q> (3) is based on methods and standards considered reliable, and (4) reliably applies those methods and standards to the facts involved in the case.93<\/a> <\/span> 93 <\/span>Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl. Young Law. Committee (DRI Young Lawyers Committee) No<\/span>. 5 (June 4, 2015).<\/span><\/sup> No case exists that discusses this potential flaw in wearable data, but it seems most likely that this will make it incredibly difficult for parties to submit wearable data as evidence in support of, or defending against, claims. To determine if wearable data were reliable under these standards, the proponent of the evidence would have to prove that the expert witness and the information the expert relied upon for their testimony were based on sound scientific methodology.94<\/a> <\/span> 94 <\/span>Daubert v. Merrell Dow Pharmaceuticals, Inc.<\/i>, 509 U.S. 579<\/a>, 593-94 (1993).<\/span><\/sup> Based on the characteristics of wearable technology, including the fact that many are incapable of distinguishing arm movement from actual steps, courts will likely determine that the science behind Fitbit and other wearables is not good science, and therefore expert witnesses will not be able to rely on or testify about such data.<\/p>\r\n\r\n\r\n

<\/a>The same problem occurs when attempting to hear expert witness testimony about the analytics process used to generate the data.95<\/a> <\/span> 95 <\/span>Kate Crawford, When Fitbit Is the Expert Witness<\/cite><\/a>, The Atlantic<\/span> (Nov. 19, 2014); Parmy Olson, Fitbit Data Now Being Used in the Courtroom<\/cite><\/a>, Forbes<\/span> (Nov. 16, 2014, 4:10 PM).<\/span><\/sup> To determine if the expert witness is relying on good science, the court must look at non-dispositive factors such as the general acceptance of the science in the scientific community, whether it can be tested, the error rate of the process, etc.96<\/a> <\/span> 96 <\/span>Daubert v. Merrell Dow Pharmaceuticals, Inc.<\/i>, 509 U.S. 579<\/a>, 593-94 (1993).<\/span><\/sup> However, these factors will be nearly impossible to examine based on the ever-increasing variety of wearable technology on the market. Many of the devices are unique in some way, and therefore, there is no standardization of the technology or the processes the analytics companies use to produce the summarized data from wearable devices.<\/p>\r\n\r\n\r\n

<\/a>With a lack of standardization in the science or scientific knowledge of the methodology, wearable devices cannot be determined to be good science and will not be admissible under the Daubert<\/i> test and Rule 702.97<\/a> <\/span> 97 <\/span>Daubert v. Merrell Dow Pharmaceuticals, Inc.<\/i>, 509 U.S. 579<\/a>, 593-94 (1993).<\/span><\/sup> This determination also correlates with the requirements previously discussed under Rule 403, because if the data fails Daubert<\/i>, it fails 403. If the data and technology of wearables were reliable science, then it would not fail the probativity test under Rule 403. However, because wearable devices have been determined to be unreliable \u2014 as shown by the devices failing to track activity data accurately, having users forget to wear the device at all, and users can manipulate the device to show the data they want \u2014 they cannot meet the standards required under the Daubert<\/i> test and therefore also fail the probativity test under Rule 403. Due to the incredible chance for bias and prejudice that outweigh the benefits of using data from wearable devices, it is vital that the courts impose strict reliability and probativity standards when determining if the parties are allowed to use such evidence in their cases.<\/p>\r\n\r\n

\r\n<\/a>V. Conclusion\r\n<\/h2>\r\n\r\n

<\/a>The historical context of the electronic discovery of wearable technology is limited, primarily because the technology is still incredibly new and still developing. Using data collected from Fitbits and other wearable devices has just begun. Legal professionals still need to learn how and when to use the data properly, and how to maximize the advantages of this new technological source of evidence for their clients.<\/p>\r\n\r\n\r\n

<\/a>As a result of this continued development and educational process, the uses and limitations of ESI stored on wearable devices may continue to change in the next several years. The accuracy and reliability of these devices is continuing to improve and this will help diminish concerns over the use of wearable device data as evidence, particularly as they become more connected to other devices, such as portable phones and computers, already used as evidence in court.98<\/a> <\/span> 98 <\/span>Elizabeth Sorenson Brotten, Every Move You Make, Every Step You Take, I\u2019ll Be Watching You<\/q>: Is Wearable Data Your Next Discovery Tool in Personal Injury Litigation?<\/cite><\/a>, 11 Newsl. Young Law. Committee (DRI Young Lawyers Committee) No<\/span>. 5 (June 4, 2015).<\/span><\/sup> However, as the technology currently stands, wearable devices lack the reliability necessary to be considered on their own, and therefore should be used as evidence in an extremely limited capacity.<\/p>\r\n\r\n\r\n

<\/a>It is possible for courts to continue allowing ESI from portable devices under the current Federal Rules of Evidence, if they slightly expand the discovery-net and recognize a few standards specific to wearable devices.99<\/a> <\/span> 99 <\/span>See Erik Harris, Discovery of Portable Electronic Devices<\/a><\/i>, 61 Ala. L. Rev.<\/span> 193, 193-222 (2009); Serge Jorgensen, Convergence of Forensics, Ediscovery, Secure, & Law<\/cite><\/a>, 12 Ave Maria L. Rev<\/span>. 291, 291-311 (2014).<\/span><\/sup> Nevertheless, it is more likely that courts will not rely entirely on this data due to the unreliable technology behind the wearable devices.<\/p>\r\n\r\n\r\n

<\/a>The discovery of wearable technology will impose several burdens on courts and the parties, based on the very nature of the data. Although the data will be difficult to introduce as evidence because of the relevancy and reliability of the information, this data has the potential to be valuable to the parties involved in the litigation of personal injury and workers\u2019 compensation cases. However, the potential value of the data does not replace the reliability concerns that plague the data and technology behind the wearable devices. Therefore, to ensure reliability, parties should be encouraged to supplement the ESI obtained from wearable technology with other forms of traditional evidence, such as doctor\u2019s testimony, expert witness testimony, plaintiff testimony, medical records, surveillance, etc. Though this too has its flaws based on the evidentiary hurdles involving Rule 702 and the Daubert<\/i> test.<\/p>\r\n\r\n\r\n

<\/a>The time has come to recognize and utilize the fact that our daily lives are monitored by a highly networked and personal set of wearable devices that generate very specific data, pertaining to our physical and mental well-being. However, it will need to become more reliable before an evidentiary onslaught of wearable data can begin to take over the justice system.<\/p>\r\n\r\n
