Augmented reality is a way to enhance mobile games and can be easily implemented on today's powerful smartphones. Developers need to consider additional constraints when choosing the input method for such an AR game. We implemented three control methods for a mobile AR multiplayer fighting game using a virtual joystick, a touch interface and continuous crosshair tracking. We evaluated the effect of the control methods on the game experience with 43 participants and conducted a survey using a questionnaire for intuitive use (QUESI [1]) and individiual interviews. We found significant differences between two of the three implemented input methods, but in the interviews the test persons did not prefer the control method with the highest survey score.
