        <p>With the imminent ubiquity of data, the healthcare domain is turning to data to increase eficiency an d ef ectiveness. Hea lth data tracking in everyday life introduces challenges around user protection, data quality, and transparency about data goals. While adhering to GDPR legislation, data design practice has done little to protect users of health tracking tools from their data and associated mental health problems. Additionally, the quantification that many data trackers facilitate can lead to comparison, competition, and addiction. Finally, it can be dificult for users to oversee the consequences of sharing their data in consumer and research contexts. We argue that designers should take responsibility for data curation and protection when designing with data, especially in healthcare. We introduce a new breed of designer: the data futures designer, who actively seeks out the edges of data tracking and discusses these with future users to inform them, probe their responses and consequently define the future of data design, together.</p>

      <title>INTRODUCTION</title>
      <p>
        In modern society, there is very little you can do without it being
documented somewhere, from all our behaviour online to
movement through the city [
        <xref ref-type="bibr" rid="ref24">24</xref>
        ]. Data has become so embedded in our
lives that the extent of data collection is no longer visible and
comprehensible for the majority of society. With data legislation such
as GDPR [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ] and its world-wide counterparts, governments are
increasingly moving to better protect the privacy of citizens.
Nevertheless, the way in which this or similar legislation is implemented
in user data collection processes is often sneaky and obscure.
      </p>
      <p>
        With recent advancements in health tracking technology and
countless healthcare apps being released every week, the trend of
data collection has also expanded itself into the medical domain,
coined as the Internet of Health Things [
        <xref ref-type="bibr" rid="ref19 ref3">3, 19</xref>
        ]. Users are rewarded
for sharing personal data such as their mood and consumed meals
by lifestyle apps or are pressured to consent to data sharing to
receive access to specific content and functions such as activity
reports from their fitness tracker. Not only do users skip reading
the policies that they consent to, but if they would read them they
would most likely not comprehend the potential consequences of
sharing their data.
      </p>
      <p>
        In order to unwrap the issue of (over)extensive data tracking, we
look specifically at health tracking in the medical domain. Especially
in the healthcare domain, the promise of data-driven healthcare
has led to an enormous data surge over the last decade. We see two
major movements: user-generated health metrics (bottom-up) and
medical-industrial “data-fication” of healthcare (top-down). With
the onset of the Quantified Self movement and the introduction of
consumer health trackers such as Fitbit, Jawbone and the Apple
Watch, an era of consumer health tracking has begun.
Simultaneously, visions are being published on the healthcare of the future,
promising P4 healthcare focused on medicine that is predictive,
preventative, personalised and participatory [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. To achieve these
visions, many stakeholders turn to AI and big data as the technical
means. Inevitably, health data will become more ubiquitous,
detailed, personalised and quantified [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. However, research has also
shown that self-tracking can lead to an unhealthy self-image and
mental health problems for some users, not all users have suficient
understanding of the technology to make sense of the data they
collect, and use of data trackers also influences relationships
between patients and their doctors. These arising issues indicate that
user protection requires more than legal and ethical procedures,
and that some of the problems that arise due to data collection and
processing cannot be solved by laws alone. If we do not somehow
acknowledge that data design practice has to play its part in user
protection, consequences could be severe, not only for these users
themselves, but also for society at a larger scale as it normalizes
exploitative behavior with little oversight and regulation.
      </p>
      <p>We argue for active data curation on the design and development
side and for human-centred designers to think about which data
tracking is actually necessary, and which data tracking is desirable
for users. We lay out some of the main issues that exist in data
collection processes today and in the recent past. In order to address
these issues in the design process, we propose a new breed of
designer: the data futures designer, who considers the use of data
beyond the initial interaction between users and their data. We
posit that this specific role should be laid out in order to protect
consumers of health data tracking tools from themselves, the
datadriven world around them and from unconscious harm to others.

      <title>ISSUES WITH DATA CURATION FOR</title>

    <sec id="sec-3">
      <title>DESIGN</title>
      <p>While the recent developments in the field of health data tracking
sound positive and promising, a societal counter-movement
investigates the downsides of continuous tracking for one’s well-being.
At present, design is often too comfortably associated with the
former, not embracing the risk perspective enough. In this section, we
approach the core issues of data curation for design from a societal
perspective, then focus on healthcare and data-enabled design as a
form of a design research that targets data literacy and agency for
design. Data-enabled design is an ideal setting to showcase how
conventional design values and attitudes can lead to problematic
data use, unintentionally harming end-users in the long run.
2.1</p>
    </sec>
    <sec id="sec-4">
      <title>Self-tracking your freedom away</title>
      <p>
        There are numerous studies that have indicated issues with data
logging and extensive tracking of habits and bodily measures. These
studies have shown that aiming at an always better, fitter, slimmer
and healthier body can have severe consequences for the mental
health of excessive users of health tracking technology [
        <xref ref-type="bibr" rid="ref16 ref23">16, 23</xref>
        ].
2.1.1 Upward or downward spiral. As there are always aspects of
health, vitality and well-being that can be improved, your fitness
tracker will never tell you that you are ‘done’, or that you have
reached your ultimate healthy body and living pattern–conceptually
an unbounded positive feedback loop. For some, constant
competition can be motivating and lead to behaviour change, but these are
also likely to already be interested in exercising and performing
healthy behaviour. For many others, competitive motivation is not
efective and quantification of exercise does not work as motivation
for everyone [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]. Fitness tracking has lead to addiction in the past,
in extreme cases even resulting in death, e.g., when a cyclist went
downhill so fast to beat a record in a cycling app that he propelled
himself to his own death [
        <xref ref-type="bibr" rid="ref16">16</xref>
        ]. These obsessive behaviours are not
strange when we look at the way in which health tracking apps
and devices have been designed. They ofer extrinsic rewards for
healthy behaviours and push you to push yourself constantly and
to always be self-critical.
2.1.2 Competition and comparison. Furthermore, health tracking
apps often have elements of gamification, competition and
performance sharing to keep users and their network engaged [
        <xref ref-type="bibr" rid="ref28">28</xref>
        ].
The constant quantification and comparison of one’s life to that of
others can have detrimental efect on mental health and lead to
compulsive or even addictive behaviours on the one hand, and lack of
self-worth and depression on the other hand. Though users do quit
these applications for the sake of their mental health through what
is often referred to as a ’detox’, feelings of guilt over not sharing
progress or not “being their best self”, i.e., integrating and
leveraging metrics in their everyday life successfully, remain [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ]. This
makes the health tracking addiction extremely complex as the habit
of health tracking is still perceived as something that will improve
one’s health, while it simultaneously causes averse side efects to
users’ mental health. To add onto that, the negative side-efects
of self-quantification are not something that users are generally
warned about, as the overall, net-positive efects of the habit are
still seen as something positive. This form of utilitarian ethics [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ]
can fail for the individual: while it is by now generally accepted
that packets of cigarettes state that smoking is addictive and deadly,
that bottles of alcohol indicate a recommended daily maximum,
and that borrowing money costs money, there is no warning or
indication of the possible side efects that health tracking might
have when you install an app or buy a tracking device. An app store
is not a pharmacy, nor should it be.

      </p>
    </sec>
    <sec id="sec-5">
      <title>Self-tracked data in a clinical context</title>
      <p>
        In medical and even clinical settings, there is an increasing interest
in collecting contextual and self-tracked data from patients [
        <xref ref-type="bibr" rid="ref2 ref27 ref9">2, 9, 27</xref>
        ].
The contextual and real-time information about patient well-being
can for example be used to prevent chronic and complex diseases
such as diabetes [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ], predict and prevent hospital re-admissions,
and reduce costs [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Self-monitoring is also being used to keep an
eye out during rehabilitation processes, which has allowed patients
to take more responsibility over their own health, even increasing
medication adherence [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. Furthermore, contextual data has made
it possible to include the partners of patients in lifestyle change
programs [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ], as well as foster active collaboration between parents
and care providers while diagnosing conditions in newborns [
        <xref ref-type="bibr" rid="ref27">27</xref>
        ].
2.2.1 Care relationships. However, when patients are asked to
keep track of their health by either their doctor or through an
application, this can change the relationship between patient and
care provider. It can put a larger responsibility on the patient and
the care provider needs to be more reactive when responding to
versatile data that patients bring into the doctor’s ofice. When
patients collect data, it is likely that they will assume that the data
they track is also being looked at, which can put extra pressure
on their doctors as they feel an obligation to use the data in their
treatment [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ]. At the same time, patients might feel less worried
about potentially alarming health data when they are not getting
any return on their data under the assumption that ’the doctor has
looked at it, so it should be fine’.
2.2.2 Quantity over quality. Additionally, the quantified data that
is easiest to measure might move more to the foreground, and the
qualitative data that is harder to capture at a larger scale might be
neglected. Similarly, quantitative data is much easier to interpret
and agree upon, as we generally can agree that a 10 is better than a
9, while it is much harder to decide whether it is better to be sad
or to be angry. The former is generally accepted, while the latter
might be diferent from person to person and from case to case. In
many cases, however, the qualitative data such as how the patient
experiences symptoms or how they are feeling at specific moments
during a day might give much more information on how the patient
would be best helped. As people use trackers more and more often
to understand their own bodies and behaviours, they might also
start relying on the numbers more. When your phone knows exactly
what you need to do to be healthy, why would you still listen to
your body? The same could count for healthcare providers: imagine
that you are on the list for a stomach reduction surgery but your
data indicates that you lack motivation to work on improving your
lifestyle, which renders the surgery useless from your doctor’s
point of view. While the numbers might not be in your favour, the
surgery might still give you confidence, or the feeling that you are
seen. Although these factors are not as measurable as a reduction in
BMI, they could have an equal or even bigger impact on a patient’s
quality of life–and set them on a diferent path in life. It is essential
that these emotions and qualitative arguments are not lost when
striving for optimisation and quantification.
2.2.3 Health literacy. Furthermore, few users of healthcare
tracking devices actually have suficient health literacy to know exactly
how to interpret and use their own health data [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ]. Health literacy
in self-tracking can be compromised in many diferent ways, from
understanding which tools are appropriate for achieving certain
health goals, to knowing how to interpret the collected data, to
knowing how to change behaviour to achieve better results [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ].
The same counts for the side of the health providers. While they may
have an extensive understanding of the condition of their patients,
they might not know how to interpret contextual data, or they
might not even trust data that has not been gathered with clinically
approved tools [
        <xref ref-type="bibr" rid="ref29">29</xref>
        ]. Currently, interpreting the data still requires
collaboration between care providers and their patients [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ].
Furthermore, it could be hard for users of smart products to understand
underlying technical aspects of their devices [
        <xref ref-type="bibr" rid="ref21">21</xref>
        ], and thus to
understand whether the device and the advice it gives are trustworthy.
      </p>
      <p>Overall, these arguments show that merely sharing quantitative
data is often not enough and requires some additional explanation
in the shape of qualitative data. This explanation is required on both
sides: on the side of the user it is important that they are guided in
interpreting and understanding their data, but also on the side of
the care provider it is important that qualitative and quantitative
data are balanced to give an accurate representation of the patient’s
condition, while keeping the amount of data manageable in its
everyday use.

    <sec id="sec-6">
      <title>Consequences of self-tracking for others</title>
      <p>
        The undesirable consequences of sharing one’s own personal (health)
data are relatively straightforward. What might be less
straightforward are the secondary and tertiary consequences of sharing your
own personal data.
2.3.1 Unintentional exclusion. The Dutch government recently
announced that it will soon be possible to download a report indicating
which vaccinations you have received, to be used as proof for
receiving a COVID-19 vaccination. Three out of four Dutch citizens have
already indicated to be in favour of showing proof of vaccination to
enter a pub1. However, for someone who did not get the vaccination
for whatever reason (e.g., religion, political standpoint, health risk
or lack of access), this development can quickly become a source of
discrimination and exclusion. Thankfully, Dutch government has
since deemed rewarding people for vaccination undesirable2.
2.3.2 Opting out. As health tracker use is being promoted in the
medical domain, and as more and more people start participating
in the movement, it might become much harder for patients to
optout of sharing this data in the future. Health insurers have already
actively started promoting the use of health trackers [
        <xref ref-type="bibr" rid="ref18 ref23">18, 23</xref>
        ], and
the implementation of trackers in regular care programs might
make patients feel that medical care is only optimal with tracker
use, much like websites are increasingly becoming unusable when
you refuse cookies. Similarly, employers around the world have
also started handing out activity trackers to employees [
        <xref ref-type="bibr" rid="ref17">17</xref>
        ]. As an
employee, you are still free to wear the tracker or not, but not using
it might be frowned upon, or rewards could be ofered to those who
do wear it. Without strict regulation, it is only a small step from
this development to economic discrimination and marginalization

in the workplace and beyond. Furthermore, an ongoing critical
movement in the IoT domain has investigated dark patterns in
connected devices, drawing attention to the security of IoT devices,
and highlighting the possibility for providers to manipulate IoT for
their own benefit [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
      </p>
      <p>The above points indicate how acceptance of health tracking
technology can have impact beyond the individual, through
normalisation. Both through social pressure and through changing
infrastructure, society changes along with new technology. This
does not have to be a bad thing, but the problem is that if it turns
out to be bad after all, it is incredibly hard to turn it back when it
has been accepted and adopted by most. Everyone that shares their
personal health care thus contributes to normalisation of health
data tracking.
2.4</p>
    </sec>
    <sec id="sec-7">
      <title>The designer is complicit</title>
      <p>
        As HCI experts, designers and design researchers, we are
increasingly dealing with data in our design processes through
methodologies such as data-driven, data-informed, data-aware and
dataenabled design [
        <xref ref-type="bibr" rid="ref11 ref26 ref7">7, 11, 26</xref>
        ]. Acknowledging data streams within our
design work is important, but it has become clear that being aware
of data within our design work alone is not enough and that a new
perspective on data design practice is necessary [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ].
2.4.1 Diferent types of data. Designers often end up in a conflicted
position, trying to understand and satisfy user needs on the one
hand, and trying to satisfy the needs and business goals of their
employer on the other. Adding data into this mix makes it even
more conflicting as data can be used in diferent ways. Building
on data-enabled design, design research works with two types of
data: research data and solution data. Research data is data that is
collected to perform research through design: to monitor how a
design is being used in practice in order to improve the design or
to learn something new about user behaviour. Solution data is part
of the design: it is required in order for the design to function, e.g.,
by training an algorithm such that it gives personalised
recommendations [
        <xref ref-type="bibr" rid="ref26">26</xref>
        ]. As we design novel healthcare applications that work
with data, we are complicit in the collection and curation of both
types of data, and there might sometimes be overlap or confusion
about the purpose of collecting specific data. We want to collect
both types of data as we want to learn how to make our design
better and understand our user, while at the same time we want to
deliver a satisfying user experience. For a user, that confusion is
bound to be even bigger, especially when we also start using the
data to change the design that they are using along the way. When
users are asked to provide a lot of research data at the beginning,
they might expect to get a big return in the shape of solution data
as well, or even analysis or interpretation of the data. These
expectations create a continuous back-and-forth between user and
designer which could almost be seen as a negotiation between both
parties: who will get the most (data) out of it?
2.4.2 Reward and risk. The proposed benefits of using data in this
real-time manner–that both sides can use the data–often blur the
line between research and solution data: the user can potentially
get feedback on the personal data that they share, while the design
researchers learn about the context and motivations of the user. The
risk is that the boundary for users to share their data is explicitly
lowered by the design researchers by ofering the users something
in return (i.e., insight into their data and themselves). As users
are ofered something in return, they might not realise that they
are actually allowing the design researchers into some of the most
intimate corners of their lives, and that they are thus giving the
researchers the possibility to understand motives and behaviours
at a far deeper level than they would be comfortable with. When
data is collected and processed across individuals, inter-personal
patterns might emerge that the individual would never want to
share. At the same time, with highly automated data collection
comes the risk of misinterpretation and problematic data analysis
chains. This is compounded by sharing data beyond the design
researcher, perhaps in anonymised form or as a trained model. For
example, users might be more willing to share details about their
exercise patterns with a designer who is committed to designing
something to improve their personal lifestyle than they are willing
to share the same information with their doctor to determine a
treatment plan. However, what they might not realise is that this
doctor will eventually use the data gathering tool that the designer
developed. The designer is thus not a separate, neutral entity, but
complicit in the data gathering goals of their employer or business
client, which might not always be in the user’s best interest. Far
more than for traditional products and research objectives, we need
to be clear and communicate truthfully to our users not only about
the purpose of the research we conduct, but also where the results
of this research could lead us in the future.

    <sec id="sec-8">
      <title>WHAT DESIGN CAN DO</title>
      <p>Design and related disciplines such as data science, engineering,
and politics play a key role in defining how data is being used
in everyday life. The entanglement of many diferent disciplines
in the design of data technology makes the situation inherently
complex. Even more complex is to point out the discipline that is
responsible for the consequences of data technology. As practices
are intertwined, it is inherently important that these diferent
disciplines each take on part of the responsibility for the well-being of
society as well. For design, this includes not only the responsibility
to do well by our users, but also to consider the bigger picture and
the (peripheral) consequences of wide-spread data collection on
diferent aspects of life and society.</p>
      <p>In order to do well by our users and design with their interests
and societal interests in mind, we should actively involve users
not only in our design process but also in our thought process,
considering them as individuals, as groups and families, and as a
heterogeneous collective. This includes clear communication about
our objectives to study participants but also actively seeking out
opinions of potential users, in particular from those opposed to
our ideas. Design education should thus address these processes
in detail and make designers aware of their ethical responsibility,
especially around data, privacy and ways in which data technology
could inflict harm. But perhaps we should take it much further
than that. Beyond only asking users for their opinion, we could
provide them with scenarios to have an opinion about. Being open
about data means proactive confrontation with what could be. After
all, we are the designers and we have a vision for where we want
data and intelligence technology to go. If not, we should seriously
question what we are trying to achieve. Instead of asking users for
consent for cookies once our plan has been rolled out, we should ask
them before whether our terms are something they would consent
to or if they object to (parts of) it, and why.</p>
      <p>Besides an ethical perspective, there are also political and
economic perspectives to take into account. From a political standpoint,
new technology asks for new legislation. Legal and regulatory
processes that are already in place are important safeguards that need
time to be implemented fully and sometimes need to be tested
in courts. We also see that their focus might need to be adjusted.
While current legal processes are aimed at risk assessment, research
quality control and participant safety, their focus might shift more
towards the ‘why?’ and the ‘what for?’ of design research–not so
much in terms of assessing a data need for a study, but to assess
the impact of collected data more broadly. A political question
also arises about whether governments should impose restraints
on health tracking technology that is being used in public health
services.</p>
      <p>
        From an economic perspective, collecting and selling data has
slowly become one of the most efective business models in the tech
industry. As a result, IoT researchers are increasingly looking into
how to design for consumer privacy [
        <xref ref-type="bibr" rid="ref20 ref22">20, 22</xref>
        ]. The question here
is how designers can increase consumer awareness about privacy,
and whether consumers will care enough about their data and
the consequences of sharing it to pay (more) for the products and
services they use. This will be a complex endeavour as by now, so
many free products and services have been made available on the
consumer market.
      </p>
      <p>In light of these diferent perspectives, perhaps it is time for
a new profession, one which exists at the junction of ethics,
design and formal data regulation. Such an expert could go by the
name of ‘data futures designer’. Their tasks would include
informing the public about new innovations and presenting them with
scenarios for future use of data and intelligence. Besides
collecting public opinion, they would also be tasked with investigating
and documenting possible consequences of data collection, data
processing and intelligent technology. On top of consequences for
users, these would also include the consequences for others who are
indirectly afected and society from a broader, futures perspective.
Data transparency is key for the data futures designer, covering
both transparency about data being collected and the ultimate goal
that it is being collected for.</p>
      <p>We should think about which data best captures the situation and
challenge ourselves to find richness in health data by collecting as
little of it as possible. How do we decide which data really matters
and reduce this to the bare minimum to decrease the impact on
user privacy, security and potentially well-being? We should not
shy away from the qualitative data simply because it is dificult to
gather or dificult to process. We should, however, shy away from it
once it becomes invasive or ethically questionable to collect it. “It’s
just for this one time,” or “It’s only for research” can no longer be
arguments when we are collecting real-time data in real contexts
with real people. When conducting data-enabled design, it is never
just for research, and collecting the data will always have an impact
on the research subjects.</p>
      <p>Society is changing, we are finding new ways to interact with
the world around us and navigating through a new data dimension
which is often invisible, but always there. As the world around
us changes, our task as designers changes too, and so do our
responsibilities. We argue that we need to change and boost a new
definition of user experience in design, qualities that transcend
human-product interaction and redirect designers’ attention to
what really matters nowadays–with potentially reinforcing
connections between traditional user experience design and new aspects
that concern the integration of the human individual in the design
and the design process (through their data) and their struggle for
transparency of agency that is currently being lost.

      <title>CONCLUSION</title>
      <p>Data is taking up a prominent position in design practice and
designers are finding new ways to embed it into their design processes.
Tracking technologies are becoming ubiquitous in everyday life.
Future healthcare needs data and intelligence to evolve and to cater
to the changing needs of our connected society. However, we see a
struggle between sharing and protecting personal data that
designers are complicit in and need to respond to. We characterise the
problem by the case of data-enabled design and lay out the various
issues that health data tracking can bring. We argue that these
issues cannot be addressed by legal and ethical processes alone and
suggest a new breed of designer: the data futures designer. The
data futures designer creatively envisions the future and actively
seeks out diverging opinions about it, to point to directions how to
address emergent issues.</p>
      <p>Future work to further this field includes a quest towards ways
in which the data futures design perspective can be embedded in
data-enabled design projects. This will be a continuing search for
the best way to design with data while simultaneously addressing
all the pressing issues around data design. In this light we seek to
conduct interviews with experts in the field of medical data and
self-tracking, as well as experts in the field of data design, data
processing and AI in order to combine them into a data futures
design process.</p>
