What does a successful 3D interface design entail?

The successful 3D interface design should apparently be based first, “on existing research on human factors in computing systems” Second, “it should reuse interaction techniques and ideas developed be researchers.” Third, “it has to employ creativity and simple approaches that help to invent interfaces and new interaction techniques.” Finally it must use existing design models and strategies of 3D interface design.” However, there is no standards set for designing 3D interfaces. “there are still no cohesive 3D interface paradigms similar to paradigms in 2D desktop user interfaces.”
