With VE techniques, we have the flexibility to actually highlight the selected object. Most examples so far have used three-dimensional extensions of two-dimensional highlighting techniques, quite than simply doing what the term implies; applying special lighting to the chosen object. A crucial decision in designing the interaction is the choice of conceptual strategy. Specifically, ought to researchers give attention to ways during which the prevailing two-dimensional expertise may be enriched, or should the place to begin be the special attributes and challenges of three-dimensional immersive environments? Some researchers are recreating the 2-dimensional graphic user interface (GUI) desktop metaphor in three dimensions by placing buttons and scroll bars within the setting together with the consumer.
While we imagine that there’s nice promise in inspecting the very successful two-dimensional desktop metaphor as a source for ideas, we additionally consider that there are risks due to the totally different sets of problems in the two environments. Relying solely on extensions of our expertise with two dimensions would not present adequate solution approaches to 3-dimensional interaction wants, similar to flying and navigation or to points related to body-centered coordinates techniques and contours of sight. When oblique manipulation is employed, the user performs direct manipulation on an object in the VE, which in flip controls some other facet of the setting. This is an extension to VE of the idea of a widget, that is, a two-dimensional interface management used in graphics interface design. Thus one could immediately manipulate a slider that controls the background … Read More
