Google Glass allows you to view notifications by a simple glance

Google is now experimenting with a feature for Google Glass where users can open and view the full notifications by simply glancing at the screen. Prior to this update, whenever a notification chime was heard, users either had to nod their head or touch on the touchpad to open up the notification alert. With this update, Google Glass becomes even more hands-free and users can just look at the screen and Glass will let you know what surprises are awaiting your attention.
