Virtual space painting system based on transparency haptic interaction

摘要

The traditional drawing system based on the 2-D mouse can not realize the haptic interaction between operators and virtual environment. This is not available for operator to feel the interaction sensitivity. A virtual space painting system based on transparency haptic interaction is proposed. This system uses the admittance type haptic device as the information interaction interface between operators and virtual environment. This paper presents an implicit force control algorithm to adapt the control of the transparency haptic interaction device. This system use the body contact detection, the virtual force generation and smoothness to build the virtual environment. Finally, a virtual painting experiment is done. The result shows that this system could improve the transparency of the haptic interaction. It means that the real artistic creation could be realized on the computer.
