The visually impaired face a variety of practical problems when traveling outdoors as a pedestrian. In recent years, various systems have been researched and developed to help the visually impaired navigate more safely and independently. However, most of them focus on local scope navigation, such as obstacle avoidance guidance, without considering the comprehensive navigation from the current location to the destination. Existing navigation services are also designed for typical people, so the timing of instructions is not appropriate for the visually impaired. So, we created a directional navigation tool for the visually impaired. This tool outputs instructions at a time more suitable for the visually impaired by comparing the location information received by GPS with the transit point obtained from Google map API. In addition to directional navigation at corners, a countdown function to the corner and a directional navigation function for departures are also implemented. Future work is to combine this tool with local scope guidance techniques to create a comprehensive navigation system.
