Puzzle Game

Abstract

The idea of the project was build at the University of Ljubljana, Faculty of Computer and Information Science, in scope of the course Communication Methods, in collaboration with Academy of Fine Arts and Design. It’s main goal was to build an interactive system between a user and a canvas, using only a projector, infra-red (IR) transmitter and IR camera. In other words, user will be able to play some game with IR transmitter, which will be recognized by IR camera, with the main window of the application displayed on the canvas. The game implemented in the project is a puzzle and it’s just for the purpose of showing, how the system can interact with it’s surroundings. Projector projects the image on to the canvas and the player standing in front of the canvas is choosing the particles of puzzle he wants to exchange. Game has more different puzzle images to be solved, each composed of different number of particles. Number of puzzle particles grows, when the puzzle is solved. The most significant part of the project was to develop a method that recognizes the position of the IR transmitter in the image acquired from the IR camera. We will describe used methods and the difficulties we came across. We will also describe all elements needed, from the software used to hardware. The aplication can be transformed into more complex interactive system
