Abstract
Reading and following visual signs remains the predominant mechanism for navigation and receiving wayfinding information in areas without accurate GPS coverage. This puts people who are blind or visually impaired (BVI) at a great disadvantage. There still remains a great need to provide a low-cost, easy to use, and reliable auxiliary wayfinding system within indoor and outdoor spaces that complements existing satellite-based systems. Through both a user study and a quantitative study of GPS accuracies in outdoor environments, this paper highlights the need for auxiliary outdoor wayfinding tools for people with visual impairments. A deep learning-based image localization framework called PathLookup is proposed in this work for accurately providing path advancement information for outdoor wayfinding. Evaluation results show PathLookup to be highly accurate and fast potentially proving to be a valuable tool for future integration into outdoor wayfinding systems.
