Description
This paper presents workload evaluation of gaze-writing systems. As a method for evaluating user's workload of a gaze-writing system, we used NASA-TLX, a questionnaire-based method for workload evaluation. We partly modified the NASA-TLX questionnaire for users of gaze-writing systems. We experimentally compared the workloads of users of two traditional gaze-writing systems QWERTY and Dasher. The experimental results showed that the workload of QWERTY tended to be lower than Dasher.
