Effective gazewriting with support of text copy and paste

Gaze writing (text entry by eye gaze) is an indispensable way of communication for motor-disabled people. While many interfaces for gaze writing are available today, the purpose of these interfaces is just a replacement of a keyboard. In order for users to communicate more efficiently, this paper introduces an interface for text copy and paste into a gaze writing system. The interface enables a user to specify a copy range and paste text to a desired position with only gaze interaction. To overcome the lack of accuracy of gaze pointing, the proposed system adopts a model of two step cursor control, which processes initial cursor setting and adjustment in turn. The experimental results have shown that the proposed interface makes gaze writing more efficiently.
