The primary purpose of this study is to evaluate the overall quality of haptic user interfaces designed to support various science learning activities in order to obtain usability and performance data. The result showed that haptic interface could significantly affect impaired students' user performance. Audio & Tactile interface can produce significantly better user performance than the Tactile interface. Meanwhile, the learning effect could be greatly enhanced and students enjoyed the hands-on experience very much. This study should provide invaluable empirical data and some insight for the future research.
