Abstract
Aiming at the problem of imperceptible sense of interaction in existing human-computer interaction system
a control scheme based on distributed system for dynamic collision detection and virtual force interaction is presented. Force perception interaction system uses distributed design
including four parts
human-computer interaction interface management
spatial configuration solution and motion control and collision detection unit. In the process of interaction
the collision effect is processed in a hierarchical manner. The virtual force perception is constructed according to the relative geometric position of the virtual space where the model is located and the state of motion after the collision. It is mapped by the interaction management unit to physical interaction device and is perceived by the operator. The dynamic collision detection simulation system is constructed with PHANTOM omni device and Visual Studio 2010
and the virtual force interaction experiments is completed. Experimental results show that the operator can achieve force perception and interaction by force feed-back devices
and it effectively solves the problem of insufficiency of force perception effect in the interaction process.
