Embodiment Construction

[0055] A preferred embodiment of the present invention is:

[0056] refer to figure 1 A human-computer interaction method for grasping and throwing a virtual object includes four steps: 1) acquisition method of head and hand data, 2) grasping recognition based on visual perception, 3) throwing recognition based on magnetic tracking, 4) The projectile rotates in real time.

[0057] refer to figure 2 , the two magnetic receivers used in the embodiment of the present invention are installed on the data glove and the helmet respectively to collect data on head and hand movements. This virtual object grabbing and throwing human-computer interaction system includes a head tracking system ①, a hand tracking system ②, and a virtual-real fusion display system ③.

[0058] The steps of the whole working method are as follows image 3 The example detailed flowchart in is shown, including:

[0059] 1) Acquisition of head and hand data

[0060] Through the hand magnetic receiver, the...

Abstract

The invention relates to a human-computer interaction method for grapping and throwing a dummy object and a system thereof. The method provided by the invention has work steps: (1) gaining data of a head and a hand, (2) realizing grapping recognition based on visual perception, (3) realizing throwing recognition based on magnetic tracking, (4) realizing the real rotation of a projectile. The system provided by the invention comprises a grapping recognition subsystem based on the visual perception, a throwing recognition subsystem based on the magnetic tracking and a path display subsystem with the real rotation. The invention can combine the consistency movement of snatching and throwing as an interactive method and uses the augmented-reality technique for taking the dummy object as a target to be snatched and thrown. The realization of the functions only needs an optical see-through helm and a magnetic tracker to be worn (a camera is not used); thereby a user can directly perceive the shocking effect of the scene. The invention has the advantages of natural operation, high real-time, and being economical and practical.

Description

technical field [0001] The invention relates to an interaction technology, in particular to a human-computer interaction method and system for grabbing and throwing virtual objects. Background technique [0002] Augmented reality, also known as mixed reality. It uses computer graphics technology and visualization technology to generate virtual objects that do not exist in the real environment, and accurately "places" the virtual objects in the real environment through sensing technology, and integrates the virtual objects with the real environment with the help of display devices. Human-computer interaction technology refers to the technology that realizes the dialogue between human and computer in an effective way through computer input and output devices. Its emergence and growth are determined by the development of computers: scientific computers -> ubiquitous computers -> human-computer integration to improve interaction efficiency. The ideal human-computer inter...
