About the study

The challenge of outdoor wayfinding, critical for People with Visual Impairments (PVI), consists in helping users safely walk to a pre-determined nearby destination. The main focus of existing solutions from research and industry is to leverage the user's smartphone to receive safe moving directions either from a remote operator or smart app. However, multiple paths may exist to connect users with their destination, each one with unique characteristics in terms of accessibility and safety. Unfortunately, little to no attention has been paid in helping PVI decide, before even starting to walk, which path to take based on their accessibility. Thus, a barrier identified is that the followed path may not be accessible because sidewalk features such as potholes, uncontrolled crossing, interrupted sidewalks, and objects are not known in advance. The investigators' goal is to develop a mobile live, local, outside map framework called VisionWay, customized for PVI-user as a wayfinding tool to analyze, before starting to walk, the accessibility of candidate paths and choose one to the destination.
