Controlling assistive technology with head movements - a review

A significant proportion of severely disabled people need to use head movements to control assistive equipment such as communication aids, environmental control systems and powered wheelchairs. It is useful to review what head movement interfaces are commercially available or the focus of research and development and their most appropriate clinical application. Such interfaces are usually required by the most severely physically disabled people and members of the rehabilitation team may come across such interfaces rarely and be unsure of their appropriate use in a given situation.
