Abstract

The invention discloses a control method for a man-machine interaction system. The method includes the steps of obtaining images of a plurality of identification objects, wherein a plurality of identification points are arranged on the identification objects, and the identification points on the different identification objects are in different shapes; obtaining the identification points which are in different shapes from the images; grouping the identification points according to the shapes of the identification points so as to obtain geometric graphs obtained after grouping is conducted; obtaining the movement states of the identification objects by comparing the geometric shape of the current frame of the image with the geometric shape of a previous frame of the image; outputting a corresponding control command to the man-machine interaction system according to the movement states. By means of the method, the control over the man-machine interaction system is achieved at a low cost and through the relatively simple method.

Description

technical field

[0001] The invention relates to the field of human-computer interaction, in particular to a control method for a human-computer interaction system. Background technique

[0002] With the development of science and technology, the virtual reality environment is widely used in fields such as video / computer games, simulators, and computer-aided design tools. Among them, most virtual reality environments allow users to control objects in six degrees of freedom, that is, allow users to control objects to move along the horizontal axis (horizontal), along the vertical axis (vertiacal), along the zoom axis (zoom), and around the Rotate the horizontal axis (pitch), rotate around the vertical axis (yaw), and rotate around the scaling axis (roll).

[0003] In the human-computer interaction system in the virtual reality environment, an existing control method of the human-computer interaction system is: by setting a motion sensor on the tracking target (for example, th...
