Home Research And Implementation Of The Sketch In The Conceptual Design Of Display Systems Interact

Most traditional Interior Decoration Systems are bounded in the WIMP interactive mode. Users' thoughts are broken by excessive switches among selection of menu, operations on buttons and keyboard input of words.In this paper the interaction technology is discussed based on pen interaction in which gestures can be seen as one kind of interactive resources and sketch can be seen as one kind of information carrier. It can express the design ideas better so as to avoid the trouble operations of menus and buttons in WIMP. As well, it gives a natural and harmonious user interface. The main creative contributions of this paper can be summarized as follows:1. Based on the analysis of the research actuality of Interior Decoration System and its related technology, the solution based on gesture and sketch to implement interactive function in Interior Decoration System is presented.2. The technology of sketch based on a stand-alone terminal is studied. Under the guidance of cognitive psychology, gesture group is devised, expression method and recognition arithmetic of gesture is presented. Based on the analysis of user's interactive semantics, geometric constraint in 2D sketch is summarized and algorithm of interactive semantic based on constraint priority is constructed which can handle constraint and build the topology of home. Horizontal_plane and vertical_plane are constructed to resolve the problem of space mapping from 2D to 3D.3. Issue of interaction in collaborative design environment is discussed. Interaction transaction log mechanism is put forward to reduce the net burden. The definition and computation of Mark-up Face is presented to supply collaborative design environment in which the designer manipulate 3D model and the clients browse the result. Collision check strategy is put forward to resolve collisions in multi-user collaborative design system.4. A prototype is built which validated the theories presented in this paper.
