Photo Shooting - Too Much Reality in Mixed Reality?

Can and should Mixed Reality (MR) be applied to all kinds of applications? Are there cases that are not suited for tangible interaction, e. g. violent games? Violence in games is certainly a technically simple, easy to comprehend, and conceptually effective way to foster player interaction, but how far are we willing to go with tangible interfaces? The game Photo Shooting plays with the analogy between shooting a photograph and shooting a gun. It is a MR game for two players. Both players try to shoot objects of a certain color with their gun cams. The first player to score a hit wins. While the game’s title, the graphics and the action may suggest violence, in the end, all that is done is taking pictures. The game’s aim is to spark a discussion between players about the role of the mimetic representation of violence in games and may serve as possible base for an emperical evalutation. Based on Huizinga’s game theory, some arguments are shortly outlined here.
