....the region of interest on the model surface is placed at the center of the view. We call our techniques user centric because the haptic tool indicates where the user wants to view the object from, rather than where the object should be. 5. 1 Grabbing Operation In the typical grabbing operation [RH92] the object is moved preserving the transformation between the virtual probe and the grabbing point. At the instant of grabbing, two points are picked: A, a point in the object, and B, the current position of the virtual probe. The transformation TBA from the probe to the object is set constant ....

....1 Introduction Three dimensional (3D) interaction has been explored in computer graphics, virtual reality (VR) user interface and scientific visualization. A number of techniques for 3D interaction have been developed, including object selection 97a] flying, grabbing and manipulating [RH92] worlds in miniature [PBBW95] combination of different modes of speech, gesture and gaze at the interface to allow real time interaction with a graphics display, two handed interaction 97, CFH97] and exploiting proprioception [MBS97] Among them, haptic visualization, as an augmentation to ....

Early important work on intelligent navigation upon which we build includes that of Mackinlay et al. 9] and Phillips et al. 10] as well as motion control systems like those of Ware and Osborne [16] Drucker et al. 5] and Robinett and Holloway [11]. The addition of intelligent interfaces is illustrated by the work of Billinghurst and Savage [2] The acquisition of cognitive maps, a special and limited application of constrained navigation, has attracted a great deal of attention as well, as described in the work of Thorndyke, Goldin, and ....

Multiple Coverings. Another fundamental technique is the multiple covering navigation surface. Readers with mathematical backgrounds will recognize this as a relative of Riemann surfaces in complex variable theory. Here, one creates a surface that may come back to the same point by many ....

....world doesn t have to bother or know whether or not an object name denotes an LOD node (or one of its children) Navigation. The most basic interaction with a virtual world is navigating through it. We won t go into a thorough discussion of different techniques here. That can be found in [2, 8, 16, 14]. Instead, we will just state that a VR system must be easily configurable, and able to switch to a broad variety of devices such as mouse, spacemouse, boom, glove and HMD, microphone, etc. For these different devices, the VR system must provide different navigation paradigms, such as ....

In addition, tools are added as their desirability becomes apparent during use of the system. When used immersively, fixed lighting sources have proved sufficient, as the user s head position relative to the surface and light determines specular highlighting. By moving about in the scene, the ....
