Multi-mode immersive synchronous acquisition system based on eye movement tracking and brain function activity detection

Abstract

The invention discloses a multi-mode immersive synchronous acquisition system based on eye movement tracking and brain function activity detection. The multi-mode immersive synchronous acquisition system includes VR display equipment, the VR display equipment is internally provided with a display module, an eye movement acquisition module, a brain blood oxygen acquisition module and a communication module, the eye movement acquisition module is used for collecting tested eye images, the brain blood oxygen acquisition module is used for collecting a brain oxygen signal of a tested head, and theVR display equipment, the eye movement acquisition module and the brain blood oxygen acquisition module respectively realize data transmission and clock synchronization with external terminal equipment through the communication module. According to the multi-mode immersive synchronous acquisition system, the VR display equipment with virtual immersion experience is adopted in the whole acquisition system, in the whole process of testing and data collection, the interference of the external environment on tested personnel can be completely avoided, meanwhile the multi-mode immersive synchronous acquisition system takes into account simultaneous acquisition of eye movement and the brain blood oxygen signal, data transmission is conducted through the communication module directly with the external terminal equipment, and a clock synchronization mode is adopted to solve the synchronization problem of real-time characteristics and multi-mode signals.

Description

technical field [0001] The invention relates to the technical field of cognitive neuroscience, in particular to a multi-mode immersive synchronous acquisition device based on eye movement tracking-brain function activity detection. Background technique [0002] Electroencephalogram (electroencephalogram, EEG) is the spontaneous and rhythmic electrical activity of brain cell populations recorded by electrodes, which contains a large amount of physiological and pathological information, and is one of the methods of neurological function examination. EEG reflects the electrical activity and various functional states of brain tissue, and its basic characteristics include amplitude, period, phase, etc. EEG signals at specific locations can also reflect cognitive abilities. Eye tracking technology is a technology that measures the movement of the pupils of the human eye through eye movement measurement equipment, and then estimates the direction and position of the human gaze. A ...
