• The VWDB is currently under development at Ochanomizu University with the aim of realizing a new generation database system for cyberspace applications. A prototype system is constructed by integrating a virtual reality system and an object-oriented database system. Since the VWDB provides a virtual world as the user's database interface, it must support a multi-modal query language. In this paper, we investigate a design of a multi-modal query language of the VWDB. We first analyze features of the multi-modal query interactions in the virtual world and identify that multi-modal interactions cause state transitions of the virtual world. Based on this observation, we introduce a multi-modal interaction model of the VWDB query language. A world algebra and an attribute grammar based approach to characterize the state transition are reported.
