What does Wicab BrainPort mean? Why can't these two words be found in the dictionary? expand on

According to foreign media reports, scientists invented a device called "Wicab BrainPort", which is specially used to help blind people and people with low vision, so that blind people and people with low vision can see the scene in front of them with their tongues.

Scientists first install a miniature digital camera in the lens of glasses, and use the camera to shoot the information of light scattered by external objects, and then use the "Wicab BrainPort" to collect the information shot by the camera and transmit it to the electrodes, which are placed on both sides of the tongue in a lollipop-like arrangement.

The article published in the American Journal of Science explains the principle of this device. The camera installed in the lens shoots the information of the scattered light of the object and transmits it to a device the size of a mobile phone, named Wicab BrainPort, which converts the information of the scattered light of the object into an electric pulse signal, which is equivalent to the function of the retina. The retina is located behind the eyes, which can convert the information of light scattered by external objects into nerve impulses signals, and then transmit the signals to the brain through the optic nerve. This device then sends electrical pulse signals to 144 microelectrodes, which are lollipop-shaped and distributed on both sides of the tongue. The electrical pulse signal continuously stimulates the nerves on the surface of the tongue and transmits this stimulation to the brain. Although it seems incredible, the experimenter's brain actually sensed these stimuli and formed the actual scene. In fact, the brain can only perceive nerve impulse signals from the retina and form images, so that we can move freely. Wicab BrainPort has zoom function and light brightness and intensity control function. Through these control keys, users can easily find the gates, elevator buttons and even read letters. On the dining table, users can see cups and knives and forks. This device seems to have great practical value, especially for blind people and people with low vision. Wicab BrainPort may be approved for sale at the end of this year (2009), and the price of each set is about US$ 65,438+00,000. The U.S. Navy has tested this device and is ready to explore its role in the Navy of SEALs.
