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.
