ChamBadge

A wearable accessible cell phone device developed as part of the Talking Braille ubiquitous computing system for indoor wayfinding. The ChamBadge combines a cell phone with a bone-conduction headset, an infrared transceiver, and wireless networking capabilities, worn behind the user's neck. It communicates with nearby Cyber Crumb nodes via infrared to receive location-specific navigation information, which is then spoken to the user through the bone-conduction headset. The device represents an early example of wearable assistive technology designed specifically for orientation and mobility of people with vision loss.
