Paper Abstract

A liquid crystal display (LCD) recently comes into common use. It is possible for this display unit to provide the same size of displaying area as the image screen on the panel. Thus the conventional display can show only one screen, but it is impossible to enlarge the size of a screen, for example twice. To solve this problem, we presented an enlarging method of display area using a mirror. Our extension method enables the observers to show the virtual image plane and to enlarge a screen area twice. Although the displaying region is doubled, the user cannot touch and point the extended screen in the mirror. In this paper, the authors propose a pointing interface for this virtual display, which realizes to point on a virtual area in the mirror.
