Design and implementation of a built-in camera based user interface for mobile games
Khoa Nguyen Tran, Zhiyong Huang · 2007
In this paper, we present a novel user interface design for mobile games using its built-in camera. It is motivated by the problem of limited number of keys on the small keypad of mobile devices. We implement two different ways, with and without the use of markers, to study the effectiveness of the design in a 2-dimensional and 3-dimensional game respectively. The algorithms implemented in the design are lightweight enough so that they are executable in real-time and at the same time, able to produce realism for the games.
