Vibrating Vest To Let Deaf People ‘Feel’ Sound (VIDEO)

A vest that allows the profoundly deaf to “feel” and understand speech is under development. The vest features dozens of embedded sensors that vibrate in specific patterns to represent words. VEST—Versatile Extra-Sensory Transducer—responds to input from a phone or tablet app that isolates speech from ambient sound.

A team of undergraduates is working on VEST with Scott Novich, a doctoral student in electrical and computer engineering at Rice University who works in the lab of neuroscientist David Eagleman. Novich devised the algorithm that enables the VEST to “hear” only the human voice and screen out distracting sounds.

‘FEELING THE SONIC WORLD’
The low-cost, noninvasive vest collects sounds from a mobile app and converts them into tactile vibration patterns on the user’s torso. Haptic feedback supplants auditory input.

The first VEST prototype put together by the team has 24 actuators sewn into the back. A second version, already in production, will include 40 of the actuators Eagleman calls “vibratory motors.” He described the experience, at least for a hearing person, as “feeling the sonic world around me.” …(read more)
