With augmented reality technology that can accurately track a smartphone’s motion through 3D space becoming more prevalent, assistive technology researchers saw the opportunity to utilize it for navigation purposes. For the past few years, Paul Ruvolo and his team have been developing Clew, a free iPhone app that helps blind and visually impaired individuals navigate recorded routes indoors. This summer, my work has centered around the addition of rerouting and pausing capabilities for the Clew app. This report will conclude with the discussion of future opportunities and limitations of the app.
