A basic experience where holograms or AR entities appear to break through the physical walls.
This simple experience only has one method of gesture input - the single Air Tap.

When wearing the HMD, the hands occlude the visualizations, so your hands appear on top of the robot holograms.
The second method of input is audible, saying "X-ray" shows you where the opponent are "inside the wall."

Outside of this simple application, you can give audible commands to Cortana, the Hololens system AI agent (like Siri but smarter). And you can use the only other Hololens recognized hand gesture - Bloom - to call up the main menu.
