An investigation of Bare-HandS-Interaction in traditional 3D game genres
Recently, stable markerless 6 DOF video-based hand-tracking devices became available. These devices simultaneously track the positions and orientations of both user hands in different postures with at least 40 frames per second. Such hand-tracking allows for using the human hands as natural input devices. To exploit these devices for interaction with an application, suitable interaction interfaces and techniques are required. Especially in the field of 3D gaming further developments and analyses of bare-handed interaction are needed. Therefore, we introduce a novel general interface for gaming purposes and analyzed various interaction modes/metaphors by coupling it to four popular 3D games (see Figure 1): two racing games, a flight simulator and a first-person shooter. Furthermore, we performed a user study based on game play in these different game genres. We present a discussion of the user study and conclude with some design principles for bare-handed interaction.
