The Aerial Object Detection app addresses the fact that standard low-tech apparatuses for the visually impaired are seriously lacking in functionality and the facility of safety. A walking stick or a can may feel out a clear path along a floor or the pavement, but it will not be able to discern any obstacles found at hip height or higher.
To make it work, this smartphone app requires the blind user to wear his handset around his neck, enabling the built-in 3D camera to receive information about the environment in front of him. Accounting for the person's pace and arrangement of surfaces, the app calculates the risk of collision and sends out an alert before such a thing can occur. The Aerial Object Detection app can sense everything from open cupboards to tree branches.
