Elderly blind people with walking disabilities have difficulties in using common navigation aids like the white cane or a guide dog. Therefore, a smart walker was developed to provide walking assistance and transmit the surrounding information of the position of surrounding objects. The handicapped receive the information via haptic feedback to avoid collisions. Obstacles are detected by a laser range finder and information of the obstacle position is transmitted to the user via a group of vibration motors on a belt around the waist. A self-rotating map was involved to display the global setting and help preplanning the route. First experiments show that after a short training period user can safely avoid collisions with obstacles in a test course.
