The map system is usually used in public places, it needs more convenient user interface. Some multi-modal interactive methods, such as spoken natural language, gesture, handwriting, etc. have been introduced into the map systems to produce more natural and intuitive user interfaces( Oviatt 1996; Adam Cheyer and Luc Julia 1996).
There is still no persuasive proof, especially the quantitative comparison, to certify that the multi-modal user interface is more natural and efficient than single-modal user interface in the domain of map applications. Although research of multi-modal interface has been around for a long time, the choice of included modalities and their combinations is usually made without any quantitative consideration.
Many studies ( Bekker, M. M., Nes, F. L.van, and Juola, J.F 1995; Ren, X., and Moriya, S 1997) have showed that evaluation experiment could help to solve this problem. The evaluation experiment makes it is possible to do quantitative analysis based on the statistical data of the result and get convictive conclusion about the optimal modality combination mode.
We set up a prototype multimodal map system, where users can use pen, spoken natural language, keyboard and mouse to accomplish some trip plan tasks. For____________________
