Eyedraw: a system for drawing pictures with eye movements

This paper describes the design and development of EyeDraw, a software program that will enable children with severe mobility impairments to use an eye tracker to draw pictures with their eyes so that they can have the same creative developmental experiences as nondisabled children. EyeDraw incorporates computer-control and software application advances that address the special needs of people with motor impairments, with emphasis on the needs of children. The contributions of the project include (a) a new technique for using the eyes to control the computer when accomplishing a spatial task, (b) the crafting of task-relevant functionality to support this new technique in its application to drawing pictures, and (c) a user-tested implementation of the idea within a working computer program. User testing with nondisabled users suggests that we have designed and built an eye-cursor and eye drawing control system that can be used by almost anyone with normal control of their eyes. The core technique will be generally useful for a range of computer control tasks such as selecting a group of icons on the desktop by drawing a box around them.
