Problems solved by technology

However, due to the limited ability of game users to complete the generation of motor imagery spontaneous potential, the number of control commands output by the system is limited, and it is impossible to experience richer game content
The commonly used compensation method is to introduce other non-brain control commands, such as voice and manual buttons. This method will not only bring a lot of artifact interference to the EEG signal, but also does not meet the needs of serving disabled people who lack motor ability. idea

Embodiment 1

[0057] The present invention is applied to 3D Tetris game Tetris 3D, in step 3) and step 4) setting left-hand motor imagination is converted into " block group moves to red wall " command, and game control key is " W "; Right hand motor imagination is converted into The game control key is "S" for the command "the block group moves to the yellow wall"; the movement imagination of the feet is transformed into the command "the block group moves toward the blue wall", and the game control key is "A"; the tongue movement imagination is transformed into " The block group moves to the green wall" command, the game control key is "D"; double blinking is converted into the "transform the reference axis of the block group deformation" command, and a single blink is converted into "control the deformation of the block on the selected reference axis" In the original Tetris 3D game, three control keys "Z", "X" and "C" are used to control the deformation of the block group on the "X", "Y" a...

Abstract

The invention discloses a man-machine interaction method supported by the multi-modal non-implanted brain-computer interface technology. The method comprises the following steps: 1) a user carries out all motion imaginations and all eye motions according to prompt signals, and the user's EOG signal and EEG signal are collected; 2) pre-treatment is carried out on the EOG signal and the EEG signal respectively; 3) an electroencephalogram classified result and an electro-oculogram classified result are obtained according to the EOG signal and the EEG signal; 4) when an external device is controlled, the user carries out the corresponding motion imagination and the corresponding eye motion according to the prompt signal, the user's current EOG signal and EEG signal are collected, and pre-treatment is carried out on the user's current EOG signal and the user's current EEG signal respectively; 5) computer control is carried out according to the user's current EOG signal, the user's current EEG signal, the electroencephalogram classified result and the electro-oculogram classified result after pre-treatment. The method can realize complex instruction output of the non-implanted brain-computer interface, and is strong in control capability on the external device.

Description

technical field [0001] The invention belongs to the technical field of multimodal brain-computer interface, and relates to a human-computer interaction method supported by multimodal non-implantable brain-computer interface technology. Background technique [0002] Brain-computer interface studies the direct information exchange between the brain and the outside world. On the basis of knowing the information expression of the human brain, a new revolutionary information and communication method is established. The initial and main research motivation is to provide assistance for patients with neurological and motor diseases. Means of rehabilitation and self-care. However, as this technology gradually enters a mature stage, a variety of emerging paradigms for more specific application requirements have been expanded based on the basic brain-computer interface system. At the same time, the concept of human-computer interaction is integrated into the design of the brain-comput...
