Application study of immersion interaction technologies in operation training simulation system

According to functions and application features of data glove and space orientation equipment, methods that controlling virtual hand and that controlling virtual arm and real arm to move synchronously have been studied and implemented. In order to achieve simulation validity, during interaction process in virtual environment, user's interaction behavior and objects' movement in virtual environment must be restricted that is implemented by using collision detection technology. Put forward concrete means that use BUMP method to implement the collision detection between virtual hand and virtual parts, use Z method to implement the collision detection between virtual human and ground, use LOS method to implement the collision detection between virtual human and other virtual objects when virtual human marches forward.
