Research on the key techniques and developing trends of multimodal user interface

The aim of user interface research is to provide an efficient way of communication for the user. With the quick development of computer software and hardware and the new introduction of Internet, the traditional user interface WIMP faces new challenges. People have been enlightened by the ideals of multimodal interface and intelligent network interface, and are seeking new generation of interface to solve the special problems resulting from the interaction between human and computer. In this paper, the key problems related to the research of multimodal interface are summarised and the corresponding resolutions are introduced. And then the limitation of these methods is pointed out. Finally, some discussions and prospects on the next generation of user interface are given.
