  • Mô tả: We systematically investigated the overall quality of haptic user interfaces designed to support visually impaired students' science learning through sensorial feedback in order to investigate task performance and user behavior. Fourteen, 6 th – 11 th grade students with visual impairments recruited from a state-funded blind school were asked to perform three main tasks (i.e., menu selection, structure exploration, and force recognition) using haptic user interfaces and a haptic device. This study used several dependent measures that are categorized into three types of variables: (1) Task performance including success rate, workload, and task completion time; (2) User behavior defined as cursor movements proportionately represented from the user's cursor positional data; and (3) User preference. Results showed that interface type has significant effects on task performance, user behavior and user preference, with varying degree of impact to participants with severe visual impairments performing the tasks. The results of this study as well as a set of refined design guidelines and principles should provide insights to the future research of haptic user interfaces that can be used when developing haptically enhanced science learning systems for the visually impaired. Article just-accepted.
