Designing new input modalities for wearables & digitized home

There is a common phenomenon in the development of wearable computers and digitized home system. The computing of these technologies has been developed expeditiously, but they still adopt conventional input methods. The wearable computer uses screen-touch or button and in-home digital objects incorporate switches or remote controllers for input methods. Although a vision based input method has been proposed, it cannot replace previous practices due to occlusion and space constraints. We propose new input modalities which can improve the physical/cognitive cost of interacting with upcoming technologies as well as the social acceptability to lower the barrier of using proposed approach.
