What technologies did David develop?

David Eagleman developed a technology involving a vest with vibratory motors designed for deaf individuals. This vest captures sound and converts it into patterns of vibration on the skin, mirroring the frequency range that the inner ear processes. This allows people to 'hear' through their skin. Eagleman's research demonstrates that the brain can adapt to receive and interpret information via unconventional sensory inputs by making correlations with other senses 1.
