Applications of Google Glass for the Visually Impaired

 

A number of low vision aids based on head mounted displays (HMDs) have been developed and even commercialized over the last 2 decades. These systems apply a few principles; Magnification with adjustable zoom has been the main approach. Basic contrast enhancement has been implemented in the commercial units, and superimposing of detected edges over the ambient scene was proposed as an augmented reality enhancement method (wideband enhancement). The same augmented reality approach using minified edges was shown to be effective aids for people with tunnel vision. Google Glass provides a unique platform that can be easily extended to become a vision enhancement tool for people with impaired vision. It is an attractive system, light weight and simple to operate, and does not interfere with eye contact in social interactions. It is easy to program and using apps will provide an attractive low cost and flexible alternative for prior designs and new concepts. The system lends itself to easy experimentation due to the high flexibility. We have embarked on a program of developing such apps implementing prior approaches as well as novel ideas. I will describe already implemented apps and others that are in development.
