Abstract

We investigate a tool to aid the viewing of PC displays by Unilateral Spatial Neglect (USN) observers by preventing overlook of the left side of the focused window. The basic concept of this tool is using observer's requests to magnify an appropriate part of the display. Based on user-interface trials, three techniques are employed: (1) whole window flashing when opening the magnifying window to realize effective attention, (2) temporal control sequence uses same special key (Ctrl, Alt, etc.) followed by normal key for easy operation by hemiplegia users, and (3) a color combination design to emphasize four sides of the focused window frame to ensure attention is paid to the left side. This tool is also effective for users with presbyopia and/or users who want to add more active window effects for presentations.
