“…Most research in this category is based on wearable products. Epp et al [11] discussed the role of wearables as an extension of the body and a media of self-expression in a social context. Walmink et al [12] presented an interactive helmet with LED display fuelled by sensor data to explore interaction techniques around wearable safety gear.…”

With the development of sensing technology and the popularization of quantified-self devices, there are increasing types of health-related data that can be sensed, visualized and presented to the user. However, most existing quantified-self applications are designed to support self-management and self-reflection; only a few studies so far have investigated the social aspect of quantified-self data. In this study, we investigated the social role of quantified-self data by introducing the design and evaluation of SocialBike—a digitally augmented bicycle that aims to increase the user’s intrinsic motivation in physical activity through on-site quantified-self data sharing. We conducted a controlled experiment on a cycling simulation system. Two forms of SocialBike’s on-bike display were evaluated with 36 participants. We used the Intrinsic Motivation Inventory to collect quantitative data about users’ intrinsic motivation in physical activity; the cycling simulation system recorded quantitative data about user behavior. Qualitative data was collected through semi-structured interviews. We conducted paired sample t-test to analyze both types of quantitative data; qualitative data were analyzed by the method of thematic analysis. The results show that SocialBike’s front display significantly increased users’ intrinsic motivation in physical activity. A total of nine themes were identified from the qualitative analysis, providing supplementary explanations for the quantitative results and additional insights into the overall design.

Skin is personal and sensitive. As a result, design and placement of on-body physical interfaces need to be well thought out. One way of "getting the design right" is to quickly sketch a multitude of designs to be modified, adjusted and elaborated on. To date, on-body rapid prototyping methods do not afford these "quick-and-dirty" design processes. We propose using piezo-resistive kinesiology tape as a low-cost and versatile resource for sketching functional on-skin interfaces. Our method uses pretreated kinesiology tape, which is made piezo-resistive through polymerization, and serves as touch, pressure and stretch sensor. We illustrate ketching techniques with both pretreated and untreated tape for iterative design of on-skin interfaces. In addition, we contribute a set of sensor primitives that facilitate various input modalities for creating interactive sketches.

Our interactions with technology do not just shape our individual experiences. They also affect people around us. Although previous research has addressed such "witness" experiences, the actual effect of interaction design on the witness experience remains largely unknown. In an online study (n = 407), we explored how witnesses perceive mid-air gesture-based interactions with a hearing aid, using four video vignettes. We studied witnesses' subjective visibility of manipulations and effects (following Reeves and colleagues' taxonomy), perceived form of interaction, subjective experience, and relationships between these measures. Although visibility patterns matched the intended form, they did not lead to the supposed experience (i.e., "suspenseful" gestures did not lead to suspenseful experiences). The paper illustrates gaps in current research about witness experiences, demonstrates the need to overcome basic hiding/revealing profiles, and indicates a path forward by focusing on aesthetic forms and experiences.
