mulTetris-a Test of Graspable User Interfaces in Collaborative Games

Most PC games are limited to a keyboard and a mouse, where the physical capabilities of the human hand are not fully taken advantage of. Based on Tetris, a traditionally single player keyboard-game, mulTetrisbrings a new easy-to-use interface involving a brick-like device as part of a collaborative game. In mulTetris, the controlling brick is tracked by a camera and is used to directly manipulate the tetrominoes. The interface is easy to learn and natural, using either the user’s existing skills, or easily transferable ones. This paper discusses each of development stages of mulTetris, the iterative design, as well as the HCI principles used in the development of the final system.
