A bicycle helmet that allows deaf friends to "hear." The helmet was Inspired by the research of theologian David Eagleman who succeeded in allowing deaf people to "perceive" the world through vibrations by transmitting sound in separate frequencies to an arranged vibration motor.

Any subtle sounds on roads are important. During the research interviews, it was found that deaf and hard-of-hearing friends often hooked off their hearing aids when using helmets due to the lack of audio information.

There are many safety challenges for deaf bicyclists. This design uses the "Sound to Motion" sensory substitution to translate road information into dynamic language, making riding safer and more comfortable.
