Blind guidance system using situation information and activity-based instruction

This study presents a situation-based wayfinding system for the visually impaired. The goal of our system is to guide visually impaired people to and from their destinations of choice. The proposed system was implemented on iPhone 4, which has embedded camera and inertial sensors. To assess the effectiveness of the proposed system, it was tested with 4 participants and the result confirmed the feasibility of the proposed system as a wayfinding aid for the visually impaired.
