....on the application. Typically, the joystick is used to navigate through environments that are larger than the CAVE itself, such as in architectural walk throughs. The buttons can be used to change modes, or bring up menus in the CAVE, or to grab a virtual object. A fish tank desktop system [1] would probably be the best alternative for those wanting a currently affordable hardware platform, allowing the user to see stereoscopic images using a computer monitor and stereo shutter glasses. However, since the visualization is written using VRML, a simple desktop computer can also be used ....

.... viewing to be a powerful technique for displaying depth information [Hubona et al. 1997; McAllister 1993; Wickens et al. 1989; Yeh and Silverstein 1990] and stereo viewing has been used as a control condition, or baseline, for studying other 3D display techniques [Sollenberger and Milgram 1993; Arthur et al. 1993]. Many of the studies do indicate the benefits of stereoscopic viewing in perceiving, recognizing, grasping and or understanding object shapes [Hubona et al. 1997; McWhorter et al. 1991; Sollenberger and Milgram 1993; Brown and Gallimore 1995; Ware and Franck 1996; Zhai et al. 1996] although some ....

Overbeeke and Stratmann [1988] and Smets [1992] demonstrated that the motion cue can be introduced through the observer s own head movement. Arthur et al. 1993] and Ware and Arthur [1993] found that the use of head tracking displays (to introduce the motion cue) had effects as powerful as stereo viewing on task completion times. Moreover, they reported that the effects of head tracking were more powerful than stereoscopic viewing on reducing error ....

....two implications on concurrency control. 1. Response time is important the time taken to access data, modify data, or notify users of changes must be as short as possible. It has been shown that a delay in the action result cycle of more than 250 msecs will deter users from using the system [Arth93]. The user may initiate an event, such as updating the geometry of an object in a scene, and expects the effect of that action to be visible within a bounded time. This time depends on the type of operation being carried up by the user, more frequent operations require shorter response times. 2. ....

....networks. For the sorts of network displays in the Document Explorer there is an increase in users abilities to perceive structure and perform three dimensional interaction tasks, as found in a number of recent studies of stereoscopic network viewing, both with and without head position tracking[69, 5]. Recent attention to immersive interfaces has focused on head mounted displays (HMDs) Such displays typically provide the user a wide field of stereoscopic view and use head position tracking to determine view. Though HMDs can be quite effective in evoking the feeling of presence necessary for ....

....movements easily and naturally change viewpoint to look around the objects. This viewing paradigm has been called fish tank virtual reality and human factors experiments indicate enhanced perception and interaction in three dimensional tasks for HTS viewing compared to flat screen presentations[5]. The Document Explorer provides stereoscopic viewing together with untethered head position tracking for HTS viewing. The enhanced three dimensional perception and interaction supplied by this display addresses the needs in our system to aid the user in perceiving structure and interacting with ....

....chooses MaxIT according to the freshness requirement of the data being disseminated. Shortening MaxIT results in fresher data, but more network traffic. For entities with strict real time delivery requirements, MaxIT must be small. For DIS terrain entities that change infrequently, recent research [3] suggests that a 1=4 second MaxIT is required to provide acceptable real time visual performance. In the Log Based Receiver reliable Multicast (LBRM) approach, illustrated in Figure 2, reliability is provided by a logging server that logs all transmitted packets from the source. When a receiver ....

....head position and using this information to estimate the actual viewpoints for both eyes. With this information, it is possible to create a set of virtual objects in the vicinity of the monitor screen such that moving around them is like moving around real 3D objects (Deering, 1992, Ware, Arthur and Booth, 1993). The apparatus we use is illustrated in Figure 1. A position tracker is mounted on the stereo glasses and this tracking information is used to estimate the positions of the user s two eyes. This is then used to construct two perspective views, one for each eye. A hand held positioning device ....
