At ATR, we have been researching the subject of "Communication with Realistic Sensations",which fits in this paradigm. This paper is based on the point of view that, although manipulation and representation have been the central issues of virtual reality research, the bottleneck lays in the difficulty of generating and modifying virtual objects interactively. Hence, there is a need to provide a means for virtual environment participants (e.g.,a team of automobile designers) to create and modify, virtual objects in real-time, in a realistic manner to convey ideas that may be difficult to express otherwise. For instance, we consider it "realistic" to describe modification of an automobile model by placing one's hand in front of its virtual image and saying "elongate to here" or by stretching the object with both hands. We have achieved some results for manipulation of virtual objects and scenes with hand gestures and natural-like language (NLL);however, this paper contributes further by introducing the idea of geometric, visual, qualitative and functional concept sets, i.e. ontologies, to describe virtual objects and the actions performed on them. Based on these ontologies, the paper proposes an interactive approach for virtual object generation, manipulation and modification with NLL, hand gesture and 2D sketch input and describes an architecture for its implementation.AN00349328全国大会講演論文集第47回データ処理3853861993-09-272015-01-20
