PERCEPT-V: Integrated Indoor Navigation System for the Visually Impaired Using VisionBased Localization and Waypoint-Based Instructions

Abstract

In this paper, we introduce PERCEPT-V, an indoor navigation system for visually impaired users that uses vision-based localization and provides real-time navigation instructions to the chosen destination including the landmarks along the path. PERCEPT-V requires no sensor deployment in the physical environment. Based on tests in three different indoor environments, the offline digital map generation process of a new environment takes less than 1 minute per 3 square meters of the environment. The system was successfully tested with 9 blind and visually impaired users. The results show that all participants are satisfied with the system and they all completed all navigation tasks using PERCEPT-V.
