Stalk is a mobile survival game where the player wears a google cardboard or gear vr headset and uses a printed tracker and the device's on board camera to track the user's hand and translate it in world space.
Essentially you have hand presence inside a mobile application using nothing more than paper, cardboard, and a mobile VR headset.
I worked with another developer in creating the tracking integration with Vuforia's api's as well as created the art assets, textures, navigational programming (ai, path planning), and game logic. Tasks were split evenly between myself and my co-developer. His focus was on Vuforia and mine was on Unity specific code and tools, the scene creation, and asset creation.
Stalk is available for both iOS and Android platforms today with hundreds of users as of now.(fall 2016)
