Google Glass may be ideal for various situations but not for driving since it acts as a distraction. Navdy, which is available for pre-order at US $319 with shipping, is a HUD (Heads Up Display) that projects navigation, alerts and notifications from your dashboard to your windshield so you don't have take your eyes off the road and thus minimizing the distraction. Navdy also promises touchless gestures a la Kinect in order to navigate or swipe away incoming calls and it includes voice recognition as well. Navdy will work with iOS and Android phones and can also integrate with a car's computer and existing set-up. This potentially game changing alert, navigation and notification HUD is expected to ship early 2015.
