Abstract: Purpose: To investigate the feasibility of using tablet device as user interface for students with upper extremity disabilities to input mathematics efficiently into computer.
Methods: A touch-input system using tablet device as user interface was proposed to assist these students to write mathematics. User-switchable and context-specific keyboard layouts were designed to streamline the input process. The system could be integrated with conventional computer systems only with minor software setup. A two-week pre¡Vpost test study involving five participants was conducted to evaluate the performance of the system and collect user feedback.
Results: The mathematics input efficiency of the participants was found to improve during the experiment sessions. In particular, their performance in entering trigonometric expressions by using the touch-input system was significantly better than that by using conventional mathematics editing software with keyboard and mouse. The participants rated the touch-input system positively and were confident that they could operate at ease with more practice.
Conclusions: The proposed touch-input system provides a convenient way for the students with hand impairment to write mathematics and has the potential to facilitate their mathematics learning.
