Application Of Pen Interaction In Virtual Decorating System

This paper is concerned about the pen application in virtual interior decorating system. It uses the existed gesture recognition technology to go deep into the research of the task, the processed model and the technology for the interaction on the base of the combination of free drawing on pen interaction and sketch design in concept design. The main content involves a knowledge library for gesture and the constraint solving technology of the ramble in the three-dimension. Thus it offers a reference model for the application of pen interaction in the interior decorating system. The system has been put into use and got good effect in the practice.1) The importance of interaction in the virtual interior decorating system is analyzed, and it is summarized that the interaction task in the virtual interior decorating system. The paper studied the consumers' thinking and object model during the virtual interior decorating system. The advantage and disadvantage of multi-modal interaction sketch CAD system interface model is analyzed, and the three-dimensional interaction sculpt paradigm is put forward. In addition, the relationship between sculpt paradigm and pen-paper paradigm is studied. As for pen-paper paradigm the system put forward the multi-modal sketch CAD system interface model based on eye and pen.2) The advantage of pen interaction in the virtual interior decorating system is analyzed. In addition, the task of interaction in the system is given. The interaction technology in the virtual environment is discussed, including technology of gesture recognition, constraint solving technology, real-time feedback technology. Besides the application of interaction technology, the feedback technology of 3D Interaction is analyzed. Finally, the paper studied the process of 3D feedback and romance, the implement strategy and the relevant technology.3) As the application of the above researches, an interior design and demonstrate system Decorator 1.0 is developed. This system has been used in the market and welcomed by consumers.
