Personal Range Finder
The Personal Range Finder is an assistive device that translates physical space into a tactile input on your arm. The goal of this project was to make an affordable mobile machine that is rugged, runs off a common power supply (9volt battery) and easy to use. The range finder utilizes sonar to create a map of the surrounding physical space. This map is then translated to a scaled pressure gradient which is applied to your forearm. In this way you are able to see the surrounding 8 feet of space allowing for informed movement without the use of your eyes.
Materials: Atmel chip, stepper motor, aluminum, hardware.
Exhibited: at the ITP Winter Show in 2006 in New York.
