Abstract

With the Apps being more popular around the world, augmentative and alternative communication (AAC) Apps also becomes an option for people with complex communication disabilities. However, the small icon might make the pointing task more difficult on the small device. This study developed an assessment tool to explore how the size of icon affects the performance of the pointing icons on the smart phone. Eight experienced smart phone users participated in a repeated measured experiment, comprised 5 sizes. The results indicated that with the size increased, the accuracy and speed decreased.
