Blowatch
Wei‐Hung Chen · 2015
The emergence of smart devices promises to bring enhanced convenience to common communication and information retrieval tasks. However, disabled users often have trouble operating touch sceens. We introduce Blowatch, a novel input method for smartwatches and potentially for other mobile devices, which provides hands-free interaction and avoid the occlusion problem. Users blow air on the smartwatches so as to invoke several operations, such as adjusting the music volume, taking a picture or answering the call. In this paper, we explore the input dimension of blowing-gesture set and examine potential usage of the gestures with a simple user study. Finally, to illustrate the potential of our approach, we developed a series of example applications for our blow-based gestures.
