Crash response system for virtual hand force feedback interaction

Abstract

The invention discloses a collision response system for virtual hand force feedback interaction, comprising a model construction module, a master-slave control module, a visual feedback module and a force feedback module. The model construction module is used for constructing a cylindrical model of a virtual hand and a spherical tree model of a virtual object. Based on the constructed model, the subsequent visual display and physical thread calculation are carried out. The master-slave control module controls the finger posture motion of the virtual hand through the posture matrix operation, and reads the interactive data of the virtual hand and the virtual object; and the master-slave control module controls the finger posture motion of the virtual hand through the posture matrix operation. The visual feedback module obtains the virtual hand position and posture graphics without penetration constraint according to the interactive data. The force feedback module processes the posture of the virtual hand model according to the interactive data to obtain the feedback force or moment, and transmits the feedback force or moment to the finger end of the operator through the force feedback device. The system can realize the visual graphics of the virtual hand without penetration, and meet the requirements of continuous and real interaction, thus enhancing the interactive authenticity.

Description

Technical field [0001] The present invention relates to the technical field of virtual reality and force feedback, in particular to a collision response system for virtual hand force feedback interaction. Background technique [0002] At present, as an important part of virtual reality technology, virtual hand interaction provides a possibility for people to touch the virtual world. Through data gloves or tracking collection devices, the advantages of human hands can be fully utilized in the human-computer interaction of the computer, and the interaction is improved. Naturalness and interactive efficiency. The appearance of wearable interactive devices such as data gloves not only means a new input channel in the process of interacting with computers, but also means that people can get more diverse feedback information from the virtual world.
