We propose a novel navigation aid system that assists the visually impaired to travel in unfamiliar indoor environments independently. The main idea of the proposed system is that it does not employ any of indoor positioning techniques. Instead, the system generates shoreline based optimal paths including a series of recognizable landmarks and detailed instructions, which enables the visually impaired to navigate to their destinations by listening the instructions on their smartphones. The paths and instructions are generated on a computer installed on an indoor kiosk where the visually impaired enters his or her destination, and then the generated instructions are wirelessly transfered to the user’s smartphone. To validate the proposed system, we developed an Android-based smartphone App and conducted the user study with three visually impaired participants. The study shows that the proposed idea is feasible, useful and potential.
