Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The application scenarios of the present invention are as figure 1 As shown, the reference numeral 10 represents a position transmitter, and the reference numeral 20 represents a position tracker, that is, a sensor. figure 2 It is a coordinate system conversion diagram according to an embodiment of the present invention;

[0036] The user operates the immersive virtual reality system, and the stereoscopic projection system, for example, uses a desktop CAVE stereoscopic projection system to generate a spatial stereoscopic image in the angle formed by the three-sided projection screen. A position tracker 20 is used in the system for head and hand tracking respectively. After the system is running, the spatial menu generated by the stereoscopic projection system is presented in front of the user. The user can dire...

Abstract

The invention relates to a method for achieving a space menu in an immersive virtual reality system. The method for achieving the space menu in the immersive virtual reality system comprises: step 1, building a space menu category and a button category and instantiating an object in the system operation process according to different demands; step 2, utilizing a position tracker to detect a manipulation means position; step 3, performing mapping match to a coordinate system of an emitter emitting the position detected by the position tracker and a coordinate system of a three-dimensional space, setting the position of the menu in the three-dimensional space according to the viewpoint position and mapping a coordinate of a manipulation means into the three-dimensional space; step 4, detecting the position of the manipulation means and an inclusion relation of a menu item and controlling the system. By means of the method, the menu can be achieved in the immersive virtual reality, and a three-dimensionally displayed virtual menu can be directly operated by fingers. The stereoscopic vision and direction operation of the finger can be integrated together, the shortcoming of a traditional method can be made up, and reality sense in the system operation can be improved.

Description

technical field [0001] The invention belongs to the field of virtual reality applications, and in particular relates to a method for realizing a three-dimensional spatial menu that can directly use fingers to control and interact in an immersive virtual reality system. Background technique [0002] Virtual Reality (VR) technology enables people to immerse themselves in a computer-generated virtual realm by simulating human sensory functions such as vision, hearing, and touch, and to interact with it in real time through natural ways such as language and gestures. It enables users to "immerse themselves" in the objective physical world reproduced by the computer, and realizes an advanced computer human-machine interface with immersion, interaction and imagination as its basic features. [0003] The characteristics of the immersive virtual reality system emphasize the sense of immersion that the system brings to the user. A general immersive virtual reality system usually pro...
