Evaluation of a Google Glass App for Smartphone Screen Zoom

Screen magnification is one of the main accessibility features used by many low-vision smartphone users. However, due to the limited screen size, interacting with magnified displays may be challenging, as the users can frequently lose context. We have developed a Google Glass app that can receive screen images of a smart phone in real time via Bluetooth connection and project the images on the Glass display in a magnified scale such that, instead of scrolling with fingers on the phone touch screen, the users could move their heads to access different screen locations. A preliminary evaluation was conducted to evaluate this technique to be used in future as a visual aid.
