“…In terms of low-cost tracking of an input device in the context of a CAVE environment, Sharlin et al propose a wireless feet tracker that can be assembled for under $200 US, and achieves an accuracy of 10cm at 20Hz [27]. This approach does not detect precise movement, nor does it determine orientation.…”

Abstract. In this paper we present a method to detect the three dimensional position and orientation of a Wii Remote with one or more emissive spheres attached to it, providing an input device that has six degrees of freedom. Unlike other systems, our system can focus in different directions surrounding the user, with a high precision, and at a low cost. We describe the way object-, motionand orientation tracking is done, as well as the applicability of the final product. We further describe how to improve the noisy data that is retrieved from the sensors of the Wii Remote, how to smooth detected positions, and how to extrapolate position and orientation.

“…Several papers have introduced new devices, such as (Sharlin et al, 2000) and (Hinckley et al, 1994), some with detailed user studies about their benefits and characteristics (e.g. (Ware and Balakrishnan, 1994;Mason et al, 2001;Myers et al, 2002)), and some with comparison with other devices in a particular task (Hinckley et al, 1997).…”

“…Although there have been attempts to develop wireless motion tracking [17], bodyposition tracking has yet to be exmnined R_q a possible interface for viewpoint motion control. In this study, we developed a prototype vision-based interface system incorporating a viewpoint control tool using body position into an immersive projection display.…”

We have developed a vision-based interface based on body position for viewpoint control in an immersive projection display. The 3D position of the arms and head of the user axe tracked by image processing without the need to attach devices to the user. This provides freedom of movement and increases the immersion in the virtual environment. Images are captured using two high-sensitivity monochrome cameras suitable for the dark condition in the projection display. The edges of both hands and the top of the head are tracked in order to control the user's viewpoint by estimating the variance of the pesition. We evaluated the utility of the interface in an experiment where subjects performed walkthrough trials in 3D space, comparing the body-position interface with a joystick. The results indicate that the performance of the body-position interface is comparable to that of the joystick in terms of viewpoint control, but enhemces the sensation of speed. The developed system is applicable as a non-contact user interface for moving around in a virtual environment.
