This would be pretty cool for a Descent clone, since the game is all about 6 degrees of freedom moving your tablet around to fly through a space would feel pretty natural.

Where this fails however is that it doesn’t seem to track the user’s face in order to properly render a parallax effect, so it does not really feel like a true portal.

I tried that and it made the gameplay worse since it harmed your ability to control the camera precisely with your hand. The goal of this is primarily to enable gameplay, and secondarily to deliver a portal effect.
