This device works for both at-home use and mobility rehabilitation training

After an especially severe case of cornea abrasion, Yee Jek Khaw found it difficult to get around—even in spaces that were familiar to him. Now, he is working on a project called Echo, an audio simulation kit that can help visually impaired users navigate a space.

Users activate the device using Wi-Fi and choose an auto track. They then use the nano suction surface of the device to attach it to a wall in a space. Once these are attached to a wall, the user can begin to orient themselves within the space. This allows for the use of another sense, hearing, to provide better spatial awareness to those with visual impairments. The idea is to keep this process simple and easy-to-use so that it can apply to a variety of places and situations.
