Chip Allows Blind People To See

crabel writes "3 blind people have been implanted with a retinal chip that allowed them to see shapes and objects within days of the procedure. From the article: 'One of the patients surprised researchers by identifying and locating objects on a table; he was also able to walk around a room unaided, approach specific people, tell the time from a clock face, and describe seven different shades of gray in front of him.'"

Re:This is actually pretty cool

I can only assume no one's that excited by huge sight-replacing devices with 512 "taxel" resolution*, except as a step toward better things.

*I've tried to imagine this and even asked Google to come up with an image that showed what this might 'look' like and come up with nothing

What I found indicated that the 512 taxels are arranged in a 32x16 grid (a 4x2 arrangement of 8x8 separate electrode grids).

Obviously it’s tactile, not visual, but I took an image off google images, reduced it to 32x16, grayscaled it, and scaled it back up using the Sinc (Lanczos3) method. This was the result.
