Adaptive 3D navigation user interface design based on rough sets

An adaptive user interface has been developed to enhance the three-dimensional navigation adaptation in this paper. Rough sets are applied to user modeling including uncertainties, namely, vagueness and incomplete information about users during their navigations in the virtual environments. We propose an approach to generate the user types´ decision-making table and identity the types by their interaction behaviors through the core reduction algorithm. Then, to structure the user adaptation templates, system can change the HCI to adapt to users´ navigation knowledge, path-finding ways and other interaction attributes. A prototype system is described at the end, and it can improve the user performances in three-dimensional navigation.
