Augmented Reality(AR) is a hot topic nowadays. To bring a better user experience which combining beautiful animation and actual interaction on reality. Base on this topic, we built a game named “AR Tower Defence” as a prototype of AR game which can touch control button without touching mobile screen. On this game, two players can compete each other in order to protecting their own mother castle, building some solider like magician and huge dragon to fight for win. Players are playing this game without using mobile phone or computer but just touching the game field which is a paper. Player can control the whole by touching the ‘paper’ and watch animation by mobile phone to have better experience on playing.
