SoniWeight Shoes: Investigating Effects and Personalization of a Wearable Sound Device for Altering Body Perception, Behavior and Emotion
説明
Changes in body perception influence behavior and emotion and can be induced through multisensory feedback. Auditory feedback to one's actions can trigger such alterations; however, it is unclear which individual factors modulate these effects. We employ and evaluate SoniWeight Shoes, a wearable device based on literature for altering one's weight perception through manipulated footstep sounds. In a healthy population sample across a spectrum of individuals (n=84) with varying degrees of eating disorder symptomatology, physical activity levels, body concerns, and mental imagery capacities, we explore the effects of three sound conditions (low-frequency, high-frequency and control) on extensive body perception measures (demographic, behavioral, physiological, psychological, and subjective). Analyses revealed an impact of individual differences in each of these dimensions. Besides replicating previous findings, we reveal and highlight the role of individual differences in body perception, offering avenues for personalized sonification strategies. Datasets, technical refinements, and novel body map quantification tools are provided.

EcoSanté Lifestyle Intervention: Encourage Reflections on the Connections between Health and Environment
説明
EcoSanté is a mobile lifestyle intervention that encourages individual behavior change while also helping participants understand the deep connections between daily lifestyle choices and our collective impact on the planet. Informed by research on “small” intervention approaches, we sent participants daily behavioral challenges that demonstrated connections between personal health and environmental impact at large. Through a 20-day mobile intervention study, 139 participants uploaded 1,920 submissions documenting their attempts to engage in these challenges. We found that participants’ self-reported healthy eating behavior and general self-efficacy improved significantly immediately after the intervention. Moreover, 30 days after the intervention, participants’ self-reported eating, exercise, and general self-efficacy all significantly improved compared to the beginning of the study. Participants had a more negative reaction when being asked to come up with their own challenges. Based on quantitative and qualitative findings, we provide implications for future researcher on mobile behavior intervention research.

Exploring the Lived Experience of Behavior Change Technologies: Towards an Existential Model of Behavior Change for HCI
説明
The majority of behavior change and persuasive technologies are exclusively addressed to modify a specific behavior. However, the focus on behavior may cloud the “existential aspects” of the process of change. To explore the lived and meaning-laden experience of behavior change, we interviewed 23 individuals who have used behavior change technology in their everyday life. The study findings highlight that behavior change is tied to meanings that point to existential matters, relates to a nexus of life circumstances, and unfolds over long periods of time. By contrast, the technology used by the participants appears mostly to focus on the present target behavior, ignoring its links to the participants’ life “context” and “time,” also providing scarce help for sense-making. Based on these findings, we surface a preliminary “existential model of behavior change,” identify several barriers that may prevent the modification of behavior and propose some design suggestions to overcome them.

Me, My Health, and My Watch: How Children with ADHD Understand Smartwatch Health Data
説明
Children with ADHD can experience a wide variety of challenges related to self-regulation, which can lead to poor educational, health, and wellness outcomes. Technological interventions, such as mobile and wearable health systems, can support data collection and reflection about health status. However, little is known about how ADHD children interpret such data. We conducted a deployment study with 10 children, aged 10 to 15, for six weeks, during which they used a smartwatch in their homes. Results from observations and interviews during this study indicate that children with ADHD can interpret their own health data, particularly at the moment. However, as ADHD children develop more autonomy, smartwatch systems may require alternatives for data reflection that are interpretable and actionable for them. This work contributes to the scholarly discourse around health data visualization, particularly in considering implications for the design of health technologies for children with ADHD.
