Abstract

Users of mouse-replacement interfaces may have difficulty conforming to the motion requirements of their interface system. We have observed users with severe motor disabilities who controlled the mouse pointer with a head tracking interface. Our analysis shows that some users may be able to move in some directions easier than other directions. We propose several mouse pointer mappings that adapt to the user's movement abilities. These mappings will take into account the user's motions in two-or three-dimensions to move the mouse pointer in the intended direction.
