Real-Time Image Processing with Augmented Reality Glasses for Mobile Low-Vision Users

Abstract

We present an unobtrusive wearable assistive technology for people with vision disabilities of central vision loss (CVL) and low contrast sensitivity (LCS) to be used in a mobile situation. Our technology includes a real-time overlay of an enhanced image with tunable magnification, exposure, and digital filtering on augmented reality (AR) glasses. The optical waveguide glass is wireless with simultaneous central vision enhancement with mobility capability. It enables the wearer to continue to use peripheral vision and is failsafe from electronic disruption such as power outages. Our preliminary tests with low-vision patients show that the AR glass improves patients' vision without disrupting mobility, for example, from 20/200 to 20/20 on average and patients were able to navigate through an office building environment.
