A microphone on the vest captures sounds from the environment and feeds them into an Android tablet or smartphone, which extracts the audio relevant to speech and converts it into unique patterns of vibration in about two dozen tiny buzzers (similar to the ones found in a cellphone). They compared two different algorithms for translating words into vibration. The researchers are still collecting data, but preliminary results suggest that both the deaf and hearing participants can learn to interpret spoken words as patterns of vibration on the skin.
