Random Idea: Kinect and Microsoft Glass Game

The screen would have a layer of fog obstructing your view.  Your phone can see through it and lead you on your way.

It’s like the Wii U, just different set of technologies.  http://www.youtube.com/watch?v=09apkk58Ju8Imagine playing an Alan Wake style rail shooter like this.  Your phone is the flash light.  Your other hand is the gun.
