Embodiment 1

[0022] figure 1 It is a flow chart of a method for content interaction in virtual reality provided by Embodiment 1 of the present invention, specifically including steps S101 to S103, which are described in detail as follows:

[0023] S101. Acquire brain wave signals.

[0024] Electroencephalography (EEG) signals are the external manifestations of neural currents when the brain is active. It records the changes in electrical waves during brain activity and is the overall reflection of the electrophysiological activities of brain nerve cells on the surface of the cerebral cortex or scalp.

[0025] Specifically, the brainwave detection device is used to detect and obtain brainwave signals.

[0026] The brain wave detection device can be installed in the head fixing device of the virtual reality device, such as a fixed headband, or it can be an independent detection device.

Abstract

The invention, which is suitable for the technical field of the computer, provides a method and device for content interaction in virtual reality, so that problems that virtual environment control by the user is limited to a body movement or manual instruction range and the virtual environment only receives a control instruction from a user passively to carry out interaction feedback can be solved. The method comprises: acquiring a brain wave signal; analyzing the brain wave signal to obtain emotion cognition information corresponding to the brain wave signal; and according to the emotion cognition information, executing corresponding content interaction on the virtual environment. Therefore, on the premise that no body movement of manual instruction needs to be carried out, the virtual environment control is completed by using the brain wave signal directly; the emotion cognition of the user is sensed by analyzing the brain wave signal, so that the virtual environment carries out interaction feedback with the user actively; and the interaction behavior is not limited to image and touching and both the emotion state and attention state can be used as interaction ways.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for content interaction in virtual reality. Background technique [0002] Virtual Reality (VR) is a computer system that can create and experience a virtual world (VirtualWorld). Its specific connotation is: the comprehensive utilization of computer graphics system and various interface devices such as reality and control to provide immersive technology in an interactive three-dimensional environment generated on the computer. Among them, an interactive three-dimensional environment generated by a computer is called a virtual environment (Virtual Environment, VE). Virtual reality technology is a technology that can create and experience a computer simulation system in a virtual world. It uses a computer to generate a simulated environment, and uses the interactive three-dimensional dynamic scene and entity behavior system simulation of multi-source informat...
