Blind people can use their tongues to see objects

According to foreign media, scientists have invented a new device called ' Wicab BrainPort '.

The scientists placed a small digital camera in the lens, taking advantage of the light information from the camera captured by the camera, then using 'Wicab BrainPort' to collect information from the camera and on electrodes, these electrodes are placed on both sides of the tongue. This type of device is designed primarily for blind people and people with very weak eyesight, they can use their tongue through this device to be able to see the immediate sight.

In the article in the American Journal of Science explained the working principle of this device. The light information from the object was captured by the camera in the glasses and transmitted onto a small device like a mobile phone, called Wicab BrainPort.Wicab BrainPort translates the body's light information into pulse circuit signals, like the function of the retina . The retina is behind the eyeball, which can transfer light information from the object to pulse signal, then through the optic nerve to transmit signals to the brain. The device then transmits pulse signals to 144 tiny plates, which are like candy-shaped plates, placed on both sides of the tongue. Pulse signals stimulate the surface of the tongue and transmit these stimuli to the brain.

Although this is one thing that makes it hard for people to believe, the brain of the experimenter sensed those stimuli and created real scenes. In fact, the brain only senses nerve impulse signals transmitted from the eye retina and produces images, which can make us see.

Wicab BrainPort has functions such as changing focus, brightness and controlling light intensity. Users through the joystick can easily find the door, the elevator button, and even read the letter or even see the cup or plate placed above. table. This device seems to have great practical value, especially for blind people and people with poor vision.

Wicab BrainPort can be approved for consumption by the end of the year, expected to cost about $ 10,000 each.
