The study will begin with an explanatory/training session where individuals with low vision will learn to use the V-NAV (Vortant NAVigation tool) indoor navigation app, and will have the opportunity to try it for a few representative tasks. The main activity includes a take-home trial, an extended unstructured period to emulate the post-purchase experience of users, during which participants will have the opportunity to use the V-NAV in their everyday lives. Data will be collected from the users to measure the relative advantage of V-NAV compared to the user's current indoor navigation method.
