Fujitsu is working on an accessory called Ontenna for the hearing impaired. It’s a simple premise, the device vibrates more aggressively the louder a nearby sound is. For example, if you are at the movies and the scene includes an explosion, Ontenna will vibrate at maximum capacity.
The Ontenna is clipped onto a person’s hair or ear so that vibrations can be felt in place of sound for the hearing impaired.
The clip can be attached anywhere someone would want the vibration to be felt. In the hair and on the earlobe.
