A novel wayfinding system is presented with an aim to increase workplace and life independence for cognitive-impaired patients such as people with traumatic brain injury, cerebral palsy, mental retardation, schizophrenia, and Alzheimer's disease. According to psychological model of spatial navigation and the requirements of rehabilitation professionals, PDA prompting with navigation video at the right time and place can assist cognitively-impaired persons with navigating indoors or on the road. The experimental results show the computer-human interface is friendly and the capabilities of wayfinding are reliable.
