Katamari Damacy Mobile
This version of the game uses a unique method of control, by making use of a new software technology called GestureTek EyeMobile to make phones capable of detecting tilt and vibration via the built in camera on the P904i. The player moves the katamari ball forward, backwards, left and right by tilting the phone. There are traditional controls as an option to the default motion controls. "Katamari Damacy Mobile" came pre-installed on P904i model phones. Other phone models needed to download the game through the Bandai Namco Games channel. Gameplay. In "Katamari Damacy Mobile", the player  controls a highly–adhesive ball called the "katamari". The object is to make the katamari as large as possible by running over and collecting objects of increasing size. The more objects players collect, the larger the katamari becomes. Instead of using analog controllers to control the katamari as in the home console "Katamari" games, players roll the katamari by tilting the phone in the direction they want the katamari to go. Criticism. Many have noted similarities between the 904i series of phones using motion controls similar to the Wii Remote. Docomo's 904i series, however, calculates tilt based on digital  camera images; unlike the Wii and PS3 controllers which use different motion sensing technologies. An IGN review of EyeMobile-compatible "3D Tilt-a-World" warns that this type of motion control fails "if your movements are too sudden for the game to translate" and that the setup requires "a well-lit area so the camera can get a good 'fix' on an image".
