P. Tolstoi, A. Dippon Towering Defense - An Augmented Reality Multi-Device Game CHI 2015, April 18 - 23, Seoul, South Korea. (bib)
	This game aims to present a modern approach for interaction between multiple devices, such as a large screen tablet and a smartphone, using the example of a simple game like tower defense. The player interacts with the game on the tablet by using simple touch input and on the smartphone by using Augmented Reality and gestures. The position of the smartphone relative to the tablet is tracked by using feature tracking of the image on the tablet. Depending on the position of the smartphone the player can select different towers or different floors of a tower for additional interaction inside. Additionally selecting a resource node allows a player to mine it by executing the mining gesture with his smartphone. After selecting an enemy the user can perform gesture based interaction to deal damage directly to the selected unit.
