The authors wanted to help children with disabilities to draw. They knew that although they are physically handicapped, they can still move their eyes around. Through the use of eye tracking technology, they devised two version of EyeDraw and test both non-disabled and disabled people in both studies. The first version had a minimal set of features: tools for drawing lines and circles, an undo button, a grid of dots to help the user dwell at a chosen location, and a facility to save and retrieve drawings. Version 2 was implemented after feedback from the first test. They also added new features to it. Also, users can stop the group of dots, so they can look around without accidentally issuing commands. Although both groups enjoyed using both versions, the disabled group had more success using the second one.
Analysis
I feel this is an interesting way to help handicapped people draw. However, my experiences with the eye tracker indicates it would not be very useful. Of course, I do not know how precise the eye tracker in the labs are. Also, it seems that after a while, the users will get tired or get a headache.
