Wearable Vision Interfaces: towards Wearable Information Playing in Daily Life

Our objective is to realize wearable interfaces for expanding our information activities in daily life. To implement these interfaces, we employ vision-based systems, including a variety of camera, a head-mounted display and other visual devices. In this paper, we present two wearable vision interfaces; 1) object registration and retrieval and 2) virtual tablet input by fingertip drawing. In both of these interfaces, an active-infrared image sensor is used to obtain depth-dependent imagery information. This information allows the wearable computing system to easily perform the given tasks (e.g., object analysis and measurement as well as finger motion understanding). Experimental results have demonstrated the effectiveness of the proposed interfaces.
