Eye-Controlled Painting System for Disabled

The paper describes an eye-controlled painting system which enables people with severe mobility impairments to draw just by moving their eyes.We design and implement the system,and also propose some algorithms to improve the performance of eye-tracking interaction.We present a time-domain constrained eye-tracking clustering algorithm to detect fixations,and then identify eye movement behaviors,which can reduce the "Midas touch" problem.We also present a window-adaptive discrete Gaussian smoothing algorithm,which can filter noise and smooth the path of eye-movement in a reasonable way.
