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

Clinicians need historical information that does not change over time, as well as other information from the notes of others to inform their documentation--to save time, they cut and paste since that is a feature in many conventional EHRs. Copy and paste is a solution to clinicians' needs that has associated downsides including errors. As part of a study of clinicians using an innovative system...

We investigate the usability of an eye controlled writing interface that matches the nature of human eye gaze, which always moves and is not immediately able to trigger the selection of a button. Such an interface allows the eye continuously to move and it is not necessary to dwell upon a specific position to trigger a command. We classify writing into three categories (typing, gesturing, and c...

Eye typing provides a means of communication that is useful for people with disabilities which prevent using their hands for text entry. In this paper, we describe the development of the prototype gaze-controlled speller and discuss its experimental evaluation. Using scrollable virtual keyboard interface, the text input speed of 1.2 wpm was achieved. Keywords—gaze tracking; gaze writing; eye ty...
