Abstract—This paper proposes a physical interaction based travel aid system for the visually impaired. The proposed system connects two steered wheels to the waist of the user through telescopic rods. These wheels are controlled to avoid obstacles or dents in the ground, detected via two sensing modules: a depth camera and a passive fork mechanism for the wheels. When steering control is applied, the resisting force on each wheel from the ground changes and the difference between the forces makes the user unconsciously change walking direction. In this paper, we describe the navigation system and confirm its possibility of safe guidance.
