Abstract: In traditional shooting theater system, only one single scene image can be presented to all the players, and the interaction based on simulation guns is limited. In this paper, we describe a novel shooting theater system for freely moving players, which is equipped with two-view projecting system, individual surround-stereo earphone and user-customized simulation gun. To provide friendly user interaction, a new-designed strategy of simulation gun is introduced. In the end, a tennis game system is given to show the extensibility and practicability of our system.
