The Atlas Developer Kit utilizes the iPhone's gyroscope, accelerometer, and camera to gather external information by referencing markers placed on the floor. This allows it to capture your movement data in the real world, enabling a true synchronization between the player and the character in the game.
By wearing an Oculus Rift, carrying a laptop on your back, and holding a gun modified from a Razer Hydra, you can transform real space into a virtual battlefield. Simply place specific markers evenly on the ground, then open the Atlas app on your iPhone to scan these markers. Afterward, secure the iPhone to your chest, where it will identify the markers and output the player's positional data. By wearing the Oculus Rift, using the Razer Hydra gun, and connecting all devices via WiFi, you can start the game with everything synchronized.
