This paper explores the social meaning of clothing-based displays of biosignals. How do friends make sense of their own and each other’s skin conductance display in the context of a conversation? We developed Hint, a dynamic thermochromic t-shirt with ambiguous patterns that change color when its wearer’s skin conductance increases, an indication of sudden arousal. We investigated how pairs of friends, each wearing the shirt, conversed and interpreted the display. Participants shared a broad range of interpretations, and emotions such as joy and embarrassment were associated with an increase in skin conductance. Additionally, participants expressed desires for their skin conductance displays to help validate their feelings and show emotional engagement with others. We explore ambiguity in the context of clothing-based information displays and discuss how skin conductance display became part of social performance in our study. From there, we suggest framing biosignals as social cues along with facial expression, gestures, etc., and begin to question what design territories this might uncover.

This paper explores the role dynamic textile displays play in relation to personal style: What does it mean to wear computationally responsive clothing and why would one be motivated to do so? We developed a novel textile display technology, called Ebb, and created several woven and crochet fabric swatches that explored clothing-specific design possibilities. We engaged fashion designers and nondesigners in imagining how Ebb would integrate into their design practice or personal style of dressing. Participants evaluated the appeal and utility of clothing-based displays according to a very different set of criteria than traditional screen-based computational displays. Specifically, the slowness, low-resolution, and volatility of Ebb tended to be seen as assets as opposed to technical limitations in the context of personal style. Additionally, participants envisioned various ways that ambiguous, ambient, and abstract displays of information could prompt new experiences in their everyday lives. Our paper details the complex relationships between display and personal style and offers a new design metaphor and extension of Gaver et al.'s original descriptions of ambiguity in order to guide the design of clothing-based displays for everyday life.
