Problems solved by technology

[0005] In the existing technology, evoked potentials are used to realize the combination of brain-computer interface technology and virtual reality technology. The user is relatively passive when controlling, and needs virtual reality to provide specific scenes and actions for stimulation, so as to generate evoked potentials and then perform scene control. Control mode Relatively simple, generally it is to judge whether an evoked potential is generated, and then carry out related control

Abstract

The invention provides a VR electroencephalogram idea control interface system, which comprises an electroencephalogram acquisition module used for acquiring motor imagery electroencephalogram signalsactively generated by the cerebral cortex of a tester; an electroencephalogram feature extraction module which is used for filtering the acquired electroencephalogram signals and extracting electroencephalogram features; a machine learning classification module which is used for classifying the filtered electroencephalogram signals and the extracted electroencephalogram features through a pre-trained machine learning model; and a virtual reality module which is used for acquiring a classification result of the electroencephalogram signal to control a virtual reality scene. The system is moreactive to a tester, does not depend on the stimulation of a virtual reality scene, is more diversified in control method, and improves the flexibility and practical value of the system.

Description

technical field [0001] The invention belongs to the technical field of brain-computer interface, and in particular relates to a VR brain-electricity idea control interface system. Background technique [0002] Brain-Computer Interface technology (Brain-Computer Interface, BCI) is achieved by collecting electrical signals of brain cortical activity, using electrical signal data as input to the computer, and then converting it into output information and commands to specific applications or peripherals to proceed further. [0003] Virtual Reality (VR) is an experience in a simulated and immersive virtual environment, which can be similar to the real world or completely different from the real world. Applications of virtual reality can include entertainment (ie gaming) and educational purposes (ie medical or military training). In addition, different types of virtual reality technologies include augmented reality (Augmented Reality, AR) and mixed reality (Mixed Reality, MR). ...
