Development of an Effective Gaze Writing System with an Interface for Text Copy and Paste

While many interfaces for gaze writing (text entry by eye gaze) are available today, these interfaces are just a replacement of a keyboard. For more efficient gaze writing, this paper proposes a novel gaze writing system which has two kinds of gaze writing interfaces: (1) an interface for text entry and (2) an interface for text copy and paste. The interface for text entry was selected from conventional interfaces based on experiments of workload evaluation of beginner users. The interface for text copy and paste, which is newly developed in our study, enables a user to specify a text range and paste the text to a desired position with only gaze interaction. To overcome the lack of accuracy of gaze pointing, the proposed system adopts the 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.
