Abstract
When a display area is limited like mobility or ubiquitous environment, there is a problem of hiding windows when there are a lot of windows. The focus switch is necessary to refer to the hidden window. This can be said that the context of work is discontinuous. In this paper, we propose a window operation interface with context continuity. First of all, to keep the continuous context, use of user's head movements is examined. Next, typical head movement of usually work is measured with 3-D magnetic positional sensor. A method of distinguishing intentional movement and other movement is examined. A window positional control method is designed based on the results of examination. And, an evaluation experiment of this control method is conducted and effectiveness is shown. Finally, a method of face recognition by camera which don't use tethered sensor is examined, and evaluated.
