[Experiences in using an electronic tutorial device for teaching students with severe motor impairments (author's...

Named "Profi 2", a device has been developed that is the first to enable even students with very severe motor impairments to cope independently with learning material on practically all subjects. The student operates the device by means of a single, and individually adaptable, motion sensor, and, without the teacher, therapist or similar personnel having to be present, receives continual feedback information as to the correctness of how he is proceeding. Additionally, the student's individual steps are stored in order to enable subsequent evaluation to be carried out by the teacher or therapist. The micro-computer component including the capacity to discriminate between voluntary and involuntary movement, impairment-related unintentional activation is practically ruled out.
