I now have the gym ball, the main controller for the game. During code development I have been using an AIBO ball, as it is very similar in terms of hue and saturation. The AIBO ball has been extremely useful, not only because of it’s colour related properties, but also because of it’s size. The AIBO ball is far smaller than the gym ball and is therefore easier to use when sitting at the computer working on the code.The larger gym ball will be used for the game, as planned, as I believe it offers the player a more interesting gaming experience than playing with the AIBO ball. Playing with the larger ball requires the player to stand further from the screen on which the game is displayed and in turn offers the opportunity to include more players at one time as the ball can be moved anywhere within the cameras viewing range.
