Abstract
The authors have developed a simulator to help with the design and evaluation of assistive interfaces. The simulator can predict possible interaction patterns when undertaking a task using a variety of input devices and estimate the time to complete the task in the presence of different disabilities. This paper presents a study to evaluate the simulator by considering a representative application of searching icons, which was being used by able-bodied, visually impaired and mobility-impaired people. The simulator predicted task completion times for all three groups with statistically significant accuracy. The simulator also predicted the effects of different interface designs on task completion time accurately. The simulator is used to develop inclusive digital TV interfaces. A case study is presented to investigate accessibility requirements of a representative digital TV interface.
