Brainport

Have you ever heard of the BrainPort device? It is a special gadget that helps people who cannot see or hear very well.

So, imagine you have a friend who cannot see or hear very well. They put on the BrainPort device, and it has a tiny camera that takes pictures of what's in front of them. The camera sends these pictures to a small device that looks like a mouthguard, which they wear in their mouth. When they move their tongue around the mouthguard, they feel little vibrations. These vibrations help them "see" in a different way, almost like reading braille.

For example, if the BrainPort takes a picture of a person's face, the person wearing the device would feel different vibrations on their tongue for different parts of the face, like the chin or the forehead. They can learn to interpret these vibrations, kind of like how you learn to read letters and words. This helps them "see" what's in front of them, even if they can't see it with their regular eyes.

Isn't that cool? The BrainPort is like magic that helps people who can't see or hear very well understand the world around them better.
