Reflections on 5 Years of Personal Informatics: Rising Concerns and Emerging Directions
The real world use and design of personal informatics has been increasingly explored in HCI research in the last five years. However, personal informatics research is still a young multidisciplinary area of concern facing unrecognised methodological differences and offering unarticulated design challenges. In this review, we analyse how personal informatics has been approached so far using the Grounded Theory Literature Review method. We identify a (1) psychologically, (2) phenomenologically, and (3) humanistically informed stream and provide guidance on the design of future personal informatics systems by mapping out rising concerns and emerging research directions
Informing the Design of Personal Informatics Technologies for Unpredictable Chronic Conditions
Personal informatics technologies, such as consumer
fitness tracking devices, have an enormous potential to
transform the self-management of chronic conditions.
However, it is unclear how people living with relapsing
and progressive illnesses experience personal
informatics tools in everyday life: what values and
challenges are associated with their use? This research
informs the design of future health tracking
technologies through an ethnographic design study of
the use and experience of personal informatics tools in
multiple sclerosis (MS) self-management. Initial
findings suggest that future health tracking
technologies should acknowledge people’s emotional
wellbeing and foster flexible and mindful self-tracking,
rather than focusing only on tracking primary
Uncovering Bias in Personal Informatics
Personal informatics (PI) systems, powered by smartphones and wearables,
enable people to lead healthier lifestyles by providing meaningful and
actionable insights that break down barriers between users and their health
information. Today, such systems are used by billions of users for monitoring
not only physical activity and sleep but also vital signs and women's and heart
health, among others. %Despite their widespread usage, the processing of
particularly sensitive personal data, and their proximity to domains known to
be susceptible to bias, such as healthcare, bias in PI has not been
investigated systematically. Despite their widespread usage, the processing of
sensitive PI data may suffer from biases, which may entail practical and
ethical implications. In this work, we present the first comprehensive
empirical and analytical study of bias in PI systems, including biases in raw
data and in the entire machine learning life cycle. We use the most detailed
framework to date for exploring the different sources of bias and find that
biases exist both in the data generation and the model learning and
implementation streams. According to our results, the most affected minority
groups are users with health issues, such as diabetes, joint issues, and
hypertension, and female users, whose data biases are propagated or even
amplified by learning models, while intersectional biases can also be observed
Enhancing Personal Informatics Through Social Sensemaking
Personal informatics practices are increasingly common, with a range of consumer technologies available to support, largely individual, interactions with data (e.g., performance measurement and activity/health monitoring). In this paper, we explore the concept of social sensemaking. In contrast to high-level statistics, we posit that social networking and reciprocal sharing of fine-grained self-tracker data can provide valuable context for individuals in making sense of their data. We present the design of an online platform called Citizense Makers (CM), which facilitates group sharing, annotating and discussion of self-tracker data. In a field trial of CM, we explore design issues around willingness to share data reciprocally; the importance of familiarity between individuals; and understandings of common activities in contextualising one's own data
How dangerous is your life? Personalising Government open crime data
This paper discusses the use of Government Open Data and how public services based on this data can and should encourage data personalisation. We present our case study Fearsquare, an application that allows people to interact with public UK crime statistics in a way that is specific to their own, individual, everyday life by leveraging the popular social media service FourSquare. This service is used as an example of how Open Data can be tailored for used in the field of personal informatics. Results suggest that the ability to personalise Government Open Crime Data using Foursquare user location history data provides an added value to an already publically available dataset
How do technological properties influence user affordance of wearable technologies?
© John Benjamins Publishing Company. The Internet of things (IoT) affords people plenty of opportunities and a higher quality of life as well as drives a huge amount of data. By drawing on the concept of affordances, this study examines the user experience of personal informatics focusing on the technological and affective nature of affordance. A multi-mixed approach is used by combining qualitative methods and a quantitative survey. Results of the qualitative methods revealed a series of factors that related to the affordance of personal informatics, whereas results of the user model confirmed a significant role for connectivity, control, and synchronicity affordance regarding their underlying link to other variables, namely, expectation, confirmation, and satisfaction. The experiments showed that users\u27 affordances are greatly influenced by personal traits with interactivity tendency. The findings imply the embodied cognition process of personal informatics in which technological qualities are shaped by users\u27 perception, traits, and context. The results establish a foundation for wearable technologies through a heuristic quality assessment tool from a user embodied cognitive process. They confirm the validity and utility of applying affordances to the design of IoT as a useful concept, as well as prove that the optimum mix of affordances is crucial to the success or failure of IoT design
