T4: A two-tap based user interface system using a touch-type device for motor-impaired company employees

This paper presents a two-tap based user interface system (T4) to reduce the burden on motor-impaired company employees by using a touch-type device such as a tablet or smartphone. The system allows the workers to send any text to an application on a daily-use PC via a Web browser, and to customize the key layout to fit their needs. The effectiveness of the system was revealed in the preliminary experiment for the motor-impaired company employees. Due to its usefulness, they expressed in an interest in implementing it at their places of business.
