This document contains information on the basic concepts behind Cyberspacevisualization and interaction techniques.1.1. Introduction:Introduction: DefiningDefining InterfaceInterface the lag is especially noticeable

For example,a lag between when you turn your head and when the screen updates is quite disturbing.Another possibility which is introduced with Cyberspace is sensory overload. Individual learning and preformance styles differ greatly, and without pro
6、per calibration an “immersive“ experience can be confusing and even disturbing.According to Bricken, there are four general categories of VR behavior that have to be considered when designing the interface:RelocationRelocation - simple movementManipulationManipulation - modification of environmentCo

Without the keyboard there is no “hot-keys“. All traditional methods of interface are not possible inside the virutal world. New
8、 methods of interaction for the above four catagories must be designed - that is the challenge of cyberspace interface design.3.3. ProcessProcess VisualizationVisualization3.1.3.1. SurfaceSurface ActivationActivationMost current views of Cyberspace seem to point towards a polygon-based environment.
9、Therefore,in order to keep the experience immersive, no menus can “magically“ pop-up. Instead, the polygons themselves must be used as an interface method. Since a single shape may have more than one function, it is therefore logical to assign function activation to the surfaces of the object.Each s

This could mean that while youre evaluating a certain button, it would also be evaluating you. To make the interface more friendly, surfaces could “announce“ (through text messages or perhaps digit
11、ized sound) what their function is. It also follows, that the surface would “highlight“ itself in order to indicate to the user that it is about to be activated, or has been activated.For example, picture a text editor as a box. To edit the file within it you would approach the top, to check the spe
12、lling you would approach another side, to delete it- yet another side. This may seem a bit cryptic, but with appropriate labeling (either graphic, sound, or text) it would be far easier than current interface methods.Surfaces could have a variety of functions - from sending a file or activating a pr

A primary factor in how an object physically appeared would then be based upon the functionality of its surfaces - this could be imp

It is recommended to answer the following questions in order to provide a thorough description of the exhibit: What is unique abo

By including the answers to these questions in the virtual tour, the audience should be able to understand what makes the exhibit so memorable. Descriptions in a virtual tour have

This can also be useful for visually impaired people who benefit from description.

There are two basic ways to go about creating guidance in a virtua
