In this paper, we report on the Wii Multimodal system (WiiMS) a system which simulates mouse and keyboard interaction for motor-impaired users. The human interface is made through a head tracking pointer which consist of a Wii Remote control and Infra-Red LEDs attached to a pair of glasses. WiiMS combines the use of head tracking with speech recognition to provide a simple and easy-to-use user interface for users with motor impairments. A user study was carried out to investigate the following: learnability, intuitiveness, user satisfaction and effectiveness of the WiiMS. WiiMS was found to be learnable, effective, satisfactory and intuitive but was not efficient for text entry even though the proposed system was found to be adequate in the context of use.
