Smartphone App for Visually Impaired to Detect Direction using Vanishing Point

Abstract

Visually impaired people may encounter accidents such as colliding with obstacles or falling due to steps when going out. In particular, falling from a station platform poses a significant danger. One cause of such falls is losing their sense of position and direction. To address this issue and support visually impaired people in navigating safely, this study aims to develop a smartphone application that determines the vanishing point from camera images and tell that direction. Furthermore, this study will verify the usefulness of direction guidance by vanishing point in various environments and investigate the optimal detection methods.
