Fujitsu Ltd launched a service using the "Ontenna" wearable device, which converts ambient sound into vibration and light for people with hearing disabilities.
Sound converted into 256 levels of vibration, light
The Ontenna converts 60-90dB sound into vibration and light in real time. The strength of vibration changes in tandem with the strength of light, and there are 256 levels of the strengths.
The length and weight of the device are about 6cm and 25g, respectively. Equipped with a clip, it can be attached to hair (like a hairpin), collar, sleeve, etc. It does not transmit the contents of sound such as words and music but notifies the user that sound is being generated.
By operating a switch located on the lateral side of the Ontenna, the device can be switched to the "smart mode." In the smart model, the device can communicate with a microphone-equipped device called "controller," and the strength and rhythm of sound detected by the controller's microphone can be simultaneously transmitted to multiple units of the Ontenna that are located within 50 meters from the controller.
For example, if the controller is placed near a ping-pong table, the sound generated by athletes hitting the ball can be transmitted to multiple Ontenna users in the space for the audience.
Also, it is possible to vibrate multiple units of the Ontenna by using a button on the controller. For example, this function can be used for transmitting rhythm at the time of teaching how to play a music instrument.
There are no manufacturer's suggested retail prices for the Ontenna and controller, but their expected retail prices are about ¥25,000 and 30,000, respectively.
