Augmented reality for the blind

LookTel- augmented reality for the blind

Now here’s a ray of sunshine on a cloudy day. LookTel is an object identifier – you point it at something and it tells you what it is. You can teach it to recognize new objects and by aiming it at a product, the program can tell what it is using real speech and when you need to ID something on the fly, you can stick on an image sticker and read that sticker. It’s more or less a barcode and QR scanner with some image recognition thrown in, but it really could be a boon to those with failing – or failed – eyesight.

The system needs a little more computing power than is available in the average smartphone so you need a local PC to help ID some things.

Blindsight – the ability to recognize facial expressions while blind

Researchers began examining him and discovered that despite his blindness, he had maintained the ability to detect emotion on a person’s face. He responded appropriately?—?with emotions such as joy, fear, and anger?—?to a variety of facial expressions. Observed activity in his amygdala?—?the part of the brain responsible for processing emotions?—?confirmed the curious results.

TN’s rare condition is known as blindsight. Because his stroke damaged only his visual cortex, his eyes remain functional and as a result can still gather information from his environment. He simply lacks the visual cortex to process and interpret it. Sight has changed for TN from a conscious to a largely subconscious experience. He no longer has a definitive picture of his surroundings, but he has retained an innate awareness of his position in the world. He is, to some degree, able to see without being aware that he is seeing.

Seed: A blind man shocks researchers with what he sees.
