Implicit interaction system used for computer virtual assembly

Abstract

The invention provides an implicit interaction system used for computer virtual assembly, and belongs to the field of virtual assembly. According to the system, a scene knowledge model and a user knowledge model are established, and an explicit interaction knowledge base and an implicit knowledge base are constructed in combination with the scene knowledge model and the user knowledge model respectively; and an implicit intention of a user is perceived based on a scene task, a scene is perceived and zoomed in according to a position relationship between a scene object and a virtual hand, and the scene object is rotated based on a directional relationship between a characteristic surface of an object oriented bounding box and the virtual hand. According to the system, the perception ability of a virtual assembly system is enhanced and the operation and cognition burdens of the user are reduced.

Description

technical field [0001] The invention belongs to the field of virtual assembly, and in particular relates to an implicit interactive system for computer virtual assembly. Background technique [0002] With the development of information technology, human-computer interaction develops from machine-centered to human-centered, that is, machines need to cooperate with users to interact. Implicit human-computer interaction is a new type of human-computer interaction centered on people. In the implicit interaction mode, users only need to consider the interactive task itself, and do not need to pay attention to the execution method and process of the task. The scene and the user can interact with each other. [0003] In the existing virtual assembly system, human-computer interaction is mostly carried out in the form of explicit interaction. For example, in the collision detection in assembly, the objects in the scene are passively waiting for the user to approach. Manipulation co...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems in the above-mentioned prior art, and provide an implicit interactive system for computer virtual assembly. Based on the problem that the existing virtual assembly system cannot perceive the user's intention and interact with the user, through Establish an explicit interactive knowledge base and an implicit knowledge interactive base, and use the expert system to infer the user's operation intention, which improves the initiative of the scene and facilitates the user to complete the interactive task
