Overview
Signage is standard in public buildings and shows directions toward points of interest to help visitors find their way, but it has little benefit for blind people.
Our one-shot wayfinding method assists blind people indetermining the correct direction to a destination by taking a one-shot image.
This wayfinding method recognizes surrounding signage in all directions from an image captured using a 360-degree smartphone camera.
Our method provides text-to-speech feedback of the estimated direction to the destination and gives vibration alerts when the blind user faces the indicated direction.
