S.T.A.R. OPS is designed to show off the capabilities of the Structure Sensor as a six degrees of freedom (6DoF) positional tracker for virtual world experiences. Download it here.
To get the full S.T.A.R. OPS experience, make sure you try it in a space where you have room to move around. After all, part of the fun is being able to walk around in the real world, while simultaneously experiencing a completely different virtual world in your iPad.
Try crouching down. Picking up items. Even picking up items and throwing them (just make sure to hang on to your iPad!).
Hit a wall? Hold a finger in the center of the screen and rotate your body towards open space.
Other than these instructions, you're on your own. Can you beat the clock and save the world as we know it?
