| Abstract: | An electronic guidance system was used to help two multihandicapped blind persons move and carry out activities within a large setting. Both subjects had previously been exposed to a robot-assisted program. The electronic guidance system consisted of three parts: a control unit, infrared light sources, and a portable device. The portable device provided the subjects with direction feedbacks concerning the activity places. Data showed that both subjects learned to use the device and thus could profitably engage in mobility and activity. When allowed to choose between the new system and the robot, one subject preferred the robot, the other the new system. A group of parents, who were shown video-tapes of the two subjects while working with the new system and with the robot, preferred the new system. Efficacy, likableness and cost of this system and of the robot are discussed. |
