Figure 1. Multi-Touch Kit enables electronics novices to easily implement high-resolution capacitive multi-touch sensing using a commodity microcon troller (a). This supports rapid prototyping of multi-touch surfaces that are customized in dimensions, shape and materials, for applications such as paper-based interaction (b), textile multi-touch sensing with a Lilypad (c), multi-touch input on 3D printed objects (d) and everyday objects (e).
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.

Figure 1: BodyStylus combines design and fabrication of functional on-body interfaces into one integrated activity performed directly on the body. A handheld device combines the ease and directness of free-form drawing with digital assistance; visual cues provide guidance while constraints dynamically restrict inking to prevent errors. BodyStylus enables drawing on one's own body (a), as well as collaborative design (b), to realize functional epidermal interfaces (c).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
