Project DescriptionThe virtual shooter project recreates the experience of the classic light gun arcade games, while bringing them up to date with today's technology. The gun used to control the game now contains the bulk of the game's muscle, and instead of a long wire stretching back to the game console, ours uses Bluetooth to wirelessly communicate. The big advantage however, is being able to play the game on the big screen, whether it's a projector or flat screen TV, without any additional setup.

The User Interface was designed with hardware functionality and simplicity in mind.  Because the Gun uses color recognition software, the colors were chosen so there is a maximum range between color values.  The UI has a simple design which gives the user a limited number of options on every screen so there is no clutter or confusion while playing.  Adobe Flash was used to develop the UI, a tool commonly used for animations and attractive game interfaces.
