Apple’s new patent shows how its AR glasses could help those with impaired vision see again

The U.S. Patent and Trademark Office (via Apple Insider) has just granted Apple a patent for technology that could be used with the company’s smartglasses. Titled Augmented reality device to warp images, the patent reveals how Apple Glasses (as the product could be named) might be helpful to those considered visually impaired. Consumers with vision issues due to age or diabetes might be able to don a pair of the company’s smartglasses in order to see something that they couldn’t normally view.

For example, if a person has a floater that blocks a portion of their view, the glasses can use a warping technique that would allow them to see what they are missing. This would be accomplished by sending the image through a processor. The technology used in the glasses would help track the user’s line of sight to keep the warp effect enabled even when he or she starts looking elsewhere. Those without an obstruction could also benefit as the image could be magnified making it easier to see. Users with normal vision can zoom in on the fine print to make sure that they aren’t getting ripped off before signing a contract.

Apple is doing something similar with the FaceTime Attention Correction that is part of the iOS 13 update. This new feature will allow those engaged in a FaceTime video chat to look down at the screen while appearing to be looking straight into the camera to those on the other side of the chat. The fake eye contact is created by mapping the user’s face and adjusting his or her eyes during the processing of the image. Like the technology discussed in the patent, this is done in real-time.
While the illustrations in the patent show the user holding an AR device to help him/her read a display on a phone or tablet screen, the same technology can be applied to a pair of AR smartglasses.
