In this paper we propose and evaluate a framework that enables a touch-screen mobile phone to be used as a wireless game controller for multiplayer desktop-based games.
The framework is highly customizable, allowing virtual keys to be properly positioned in the device, in order to give the best layout to fit the desires of the player, which almost is impossible to achieve on devices that use physical keys like older mobile phones.
Three different schemes, based on Key Touch, Motion and Screen Touch are implemented and compared using a developed 2D shooting game in a case study of participants with minor and major experience using these kinds of devices.
