Young people who have complex physical disabilities and good cognition may face many barriers to learning, communication, personal development, physical interaction and play experiences. Physical interaction and play are known to be important components of child development, but this group currently has few suitable ways in which to participate in these activities. Technology can help to facilitate such experiences. This research aims to develop a technologybased tool to provide this group with the potential for physical interaction and physical play, by providing a means of manipulating objects. The tool will be used to develop the target group's knowledge of spatial concepts and the properties of objects. It will utilise eye gaze technology, robotics and haptic feedback (artificial sensation) in order to simulate physical control and sensations. Throughout this study, there will be a strong focus on Human Computer Interaction, as the target group has complex usability requirements.
