....Navigation metaphors are supported within the specification and can be scripted in VRML if the default behaviours do not suffice. However as mentioned in Section 3.3. 5, there is a definite bias towards desktop metaphors and several authors have noted the difficulty of supporting immersive viewing [22,21,20]. No world construction facilities are directly provided, but tools to accomplish this can be scripted. For example, although still in preliminary development VermelGen [23] is a set of Java classes that use the External Authoring Interface, to provide editing tools for many of the VRML nodes. ....

....of the application and they are not designed to explore large databases. Finally, two papers mention the mirror as a possible metaphor that deserves consideration. Ishii al. 13] present several optical metaphors and mention the mirror as a direction for future research while Edwards al. [7] discuss the implementation of several new nodes to enhance the VRML scene graph. A mirror is presented as an application of these nodes and used as a map view. 3 The Magic Mirror Tool like approaches are very attractive for user interface techniques because tools are common in real life. Tools ....

....in depth knowledge of the world geography. More elaborated solutions are based on the display of a global, simplified view of the world added in the user s field of view. 13] proposes the concepts of World In Miniature . 12] studied how 2D maps could help users to navigate in virtual buildings. [4] presents the concept of map view , a tool that allow the user to monitor its position (viewed from some satellite position) on a small virtual screen embedded in the 3D world. Although there are differences among these methods, the basic idea is to include in front of the user a small ....

....a small overall view of the world and a marker showing the position of the user in that world. For orientation awareness, 10] has pointed out the importance of the knowledge of the vertical direction and presented some upward cues such as ground planes, backdrops and directional illumination. [4] has proposed the concept of trailblazing . The basic idea is to allow the user to leave graphical markers (that act as user defined landmarks) in the 3D world. The use of landmarks can be compared to the use of hyperlinks in HTML (HyperText Markup Language) documents, trailblazers being some ....

....application. This is due to the fact that no browser supports any other devices. Work is going on by Hand to provide web support for other interaction devices e.g. HMD and 6 degree of freedom input devices, however the resulting solution is based on an in house browser rather than a standard one [63]. There are other ways around this problem as we saw in the Peloton system however they are not efficient yet. With the recent availability of Java 3D, it will be possible to support other devices in the near future. Because we adopt a server based approach, communication becomes vital for our ....

....views, a pursuit tracking mechanism i.e presenting both the target and the current position is essential. On the other hand, egocentric views are better utilised when supported by compensatory tracking mechanism, where the magnitude and direction of the divergence from the target is indicated [105, 63]. There are a number of techniques that have been adopted to solve the problem of getting lost in an environment. One way is to use trailblazing, which is to drop marks during navigation to find previous locations. Another way is to use maps to plan your route [63] Object manipulation Changing ....

....reality over the Internet. There are several limitations in this standard that prevents it from achieving its ultimate goal. One of the major drawbacks in VRML that keeps its applications chained to a desktop configuration is its user interface which does not support immersive VR. Work done by [Edwards 1996] transfers part of the VRML Distributed VR Training System for Endovascular Procedures 113 113 interface from the browser to the virtual environment, which provides the flexibility of adding interface objects as needed and from different web locations. By utilising VRML more in building VR ....
