New Device Could Overcome Low Vision

Johan Jonasson cites a story at Wired which reads in part: "Low vision can't be corrected with medical procedures, glasses or contact lenses. But a new product from Microvision that uses lasers to 'paint' rows of pixels directly onto the eye is helping people with low-vision see clearly again." "The device, called Nomad, consists of two pieces: a small control module worn clipped on to a belt, and the head-worn display. The control module receives a video signal from a computer -- a desktop, laptop or a wearable computer -- which processes this signal to drive a low-power laser. The light is then scanned by a small mirror to create images." Essentially, it's the same type of display that many wearables come with, but with the image enhanced to compensate for the low-vision user's greater needs.
