For decades, wearable research has explored different output modalities (e.g. screens, lights, scents, thermal, vibrotactile, shape change) implemented in wearable form factors. With these output modalities, prior research addresses a wide range of issues from information representation to self-expression and social cohesion. However, the close proximity of wearables to our bodies makes their design a complex task that requires attention to functional, social, and cultural aspects. Wearables are not just practical artifacts (e.g. conveying concise information for the user or the observer) but have a potential effect on our appearance and social interactions. In this workshop, we look into informative aspects and social challenges around designing different output modalities on bodies. By bringing together researchers and practitioners, we see particular potential in providing a broader perspective on the practical and social aspects of designing wearable output modalities.
