Research on Interaction Technologies in Desktop Virtual Maintenance System of Certain Weapon
In the desktop virtual maintenance system of certain weapon, the whole interaction process is divided into pickup, drag and release three phases with common interaction devices as 2-d mouse and keyboard. As the mouse only consists of 2-d screen coordinate information and the virtual entities have 3-d world coordinate, it is necessary to put up a mapping between screen coordinate system and 3-d world coordinate system. Based on the mapping, the key technologies of each phase are given including acupuncture pickup method, rough area judgment method, drag and release control methods etc. The methods of pickup, drag and release of 3-d virtual entities are applied to certain weapon desktop virtual maintenance system, and it is to be proved both the performance of real-time and the sense of reality are increased effectively.
