....Figure 2. The optical tracker in the VizRoom an overview 5. Optical tracking in virtual reality systems Virtual Reality tracking technology includes mechanical, ultra sonic and optical systems [11] However, the dominant trackers are still the electromagnetic trackers mentioned previously. In [4], Chance et al. describe a wide area tracking system in 3 DOFs based on stereo imagery, with two CCD (Charged Coupled Device) cameras and a light bulb on the user s backpack. In [24] Welch et. al describe the development of an 6 DOF optical tracker called HiBall, for HMDs. The system was motivated ....

....retrieving information by remembering where it was seen. Users manage multiple windows on the monitor in order to bring information to themselves. Chance et al. have shown that people have better memory of locations in 3D space if they turn their bodies rather than turning the world about them [3]. The presence of vestibular, proprioceptive, and somesthetic cues strongly affects spatial memory. Several interfaces, such as the Rooms metaphor [7] and Data Mountain [11] provide spatial cues by presenting a 3D space behind the single 2D display surface. However, these interfaces have had ....

Motricity BSA will be associated with the exploited artifacts, to facilitate mental I of the person. 3.6.3 The orientation on the railways The orientation poses a delicate problem. Experiments [8] showed that the real rotation of the body on itself was relatively significant for the orientation (contrary to the translations) Will the user be able to be always well oriented if a 1D travelator is exploited Tests are envisaged to analyze the solutions. 3.6.4 The visual immersion The ....

....In either case, the method of travel is important in determining spatial orientation. The studies mentioned above all assumed a simple travel technique in the VE conditions, such as constant velocity gaze directed steering (the user moves in the direction she is looking) However, a recent study (Chance et al., 1998) addresses the importance of the travel technique in a path integration task, by comparing techniques that differed in their level of similarity to movement (walking) in the physical world. They found that, in general, a technique more similar to real walking (physical translations and or ....

....spatial awareness but also reduce cognitive load levels on the user. 3 EXPERIMENT The goal of this evaluation was to compare the spatial orientation of users after traveling through an immersive virtual environment (using a HMD) using certain travel techniques. As noted in the introduction, Chance et al. (1998) found that using a physical translation technique produced better spatial orientation, although the absolute error measurements they report were still relatively high. As in their study, we chose to use a maze traversal task followed by a pointing task to measure spatial orientation. The mazes ....

....the question: How successfully then can a virtual reality system replace the natural experience of exploring an environment . Humans are able to use path integration[13, 6, 10, 1] and it is known that navigation performance is improved and cybersickness minimized when real walking is allowed[2]. Using Trike we can precisely monitor and manipulate the sensory information available during navigation tasks. Virtual Reality systems, which augment or modify one of these sensory systems, may confound our overall sensation of motion in various ways. A common result of this confusion is nausea ....

....Similarly, Loomis and his colleagues showed that Spatial representations of virtual mazes p. 3 increasing the fidelity of the VE interface (by including kinesthetic and vestibular input) significantly improved the accuracy of people s memory about short paths that they had recently traversed (Chance, Gaunet, Beall, Loomis, 1998; Klatzky, Loomis, Beall, Chance, Golledge, 1998) It is important to realize that route memory of the type studied by Witmer et al. and by Loomis et al. is largely mediated by perceptual and motor processes and generally does not require one to form a flexible mental representation of the ....

....with other experiments. To compare our results with other studies that did not use circular statistics, we calculated mean absolute error for the pointing judgments. The mean absolute error averaged over all conditions is 41:8 ffi , and for the best condition was (Northwest) 27:0 ffi . Chance et al. 1998 tested different motion models and compared the accuracy of the pointing judgments. The tested environments were not visible from one vantage point, the size of the maze was 3m by 5m. The subjects judged the directions relative to a virtual guide in minutes on an imagined clock face (i.e. 60 ....

....could only move with the joystick, the mean error was about 70 ffi . For the real walk condition, where the subjects actually had to walk, the mean absolute error was a little bit below 50 ffi . Our pointing results seem to be comparable, if not more accurate than the pointing results of Chance et al. 1998), although the subjects in our experiment had only visual and proprioceptive (VR bike) information. In comparison, the subjects in Chance et al. real walk condition had additional vestibular information available. In the following studies, it is not clear how the direction estimates have been ....
