The TiM game engine: Development of computer games accessible to blind and partially sighted children

The TiM project intends to develop and to adapt computer games for visually impaired children. This paper presents the game development platform, that allows to develop accessible games that use specific devices like tactile boards, Braille displays or speech synthesisers, as well as standard devices like keyboards and sound devices. The games can be designed without any knowledge of specific devices protocols. The game scenarii are written regardless to the devices and regardless to the language. An XML style sheet contains all raw data for each kind of device, possibly in several languages.
