Abstract: Conventional Human Computer Interaction requires the use of hands for moving the mouse and pressing keys on the keyboard. As a result paraplegics are not able to use computer systems unless they acquire special Human Computer Interaction (HCI) equipment. In this paper we describe a prototype system that aims to provide paraplegics the opportunity to use computer systems without the need for additional invasive hardware. The proposed system is a multi-modal system combining both visual and speech input. Visual input is provided through a standard web camera used for capturing face images showing the user of the computer. Image processing techniques are used for tracking head movements, making it possible to use head motion in order to interact with a computer. Speech input is used for activating commonly used tasks that are normally activated using the mouse or the keyboard. Speech input improves the speed and ease of executing various HCI tasks in a hands free fashion. The performanc e of the proposed system was evaluated using a number of specially designed test applications. According to the quantitative results, it is possible to perform most HCI tasks with the same ease and accuracy as in the case that a touch pad of a portable computer is used. Currently our system is being used by a number of paraplegics. (More)
