Exploring the Personal Informatics Analysis Gap: "There's a Lot of Bacon".

Personal informatics research helps people track personal data for the purposes of self-reflection and gaining self-knowledge. This field, however, has predominantly focused on the data collection and insight-generation elements of self-tracking, with less attention paid to flexible data analysis. As a result, this inattention has led to inflexible analytic pipelines that do not reflect or support the diverse ways people want to engage with their data. This paper contributes a review of personal informatics and visualization research literature to expose a gap in our knowledge for designing flexible tools that assist people engaging with and analyzing personal data in personal contexts, what we call the personal informatics analysis gap. We explore this gap through a multistage longitudinal study on how asthmatics engage with personal air quality data, and we report how participants: were motivated by broad and diverse goals; exhibited patterns in the way they explored their data; engaged with their data in playful ways; discovered new insights through serendipitous exploration; and were reluctant to use analysis tools on their own. These results present new opportunities for visual analysis research and suggest the need for fundamental shifts in how and what we design when supporting personal data analysis.

Older adults' perceptions of community-based telehealth wellness programs: a qualitative study.

As older adult populations rise in the United States, community-based telehealth programs are gaining momentum because of their ability to provide telehealth services for community-dwelling older adults at a lower cost compared to home-based telehealth services. The success of such community-based telehealth programs heavily depends on end-user engagement and acceptance; however, few studies to date have explored these issues. We conducted an interview study with 14 active and 3 inactive participants of a community-based Telehealth Intervention Program for Seniors (TIPS) to examine older individuals' perceived benefits and barriers to participating in community-based telehealth programs as well as strategies to improve those programs. We found that older adults had a positive experience toward the use of telehealth services in a community setting, including benefits like monitoring health status and enabling socialization. There were no perceived barriers about the telehealth program. Aspects that can be improved include facilitating the management and sharing of historical physiological data, providing additional assessments of cognitive and/or mental status, supporting self-education, and enabling more comprehensive health status tracking. We conclude this paper by discussing the implications of our results to the improvement of community-based telehealth programs for low-income, vulnerable aging populations.
