Abstract

The invention discloses a head-mounted brain evoked potential visual stimulation system based on a VR head display, comprising a wearable VR device which can be worn on the eyes of a user; And a visual stimulus setting module for setting a specific form and parameters of the presented visual stimulus; A VR presentation module for presenting the set visual stimulus as a picture; A user feedback module for collecting a fatigue index of a user under a particular visual stimulus and feedback adjusting parameters of the visual stimulus setting module. A method for evoke visual potentials use that system described above is also provided. The visual stimulation system of head-mounted brain evoked potential based on VR head display and the use method have the advantages of being portable, real scene, providing multiple stimulation paradigms, and being able to adjust stimulation parameters according to user fatigue condition, and have good popularization prospect.

Description

technical field [0001] The invention relates to the technical field of brain-computer interface and virtual reality interaction, in particular to a head-mounted brain-evoked potential visual stimulation system and method based on a VR head display. Background technique [0002] Brain Computer Interface (BCI) is a new external information exchange and control technology that establishes between the human brain and computers or other electronic devices that does not rely on conventional brain information output pathways (peripheral nerves and muscle tissue). The purpose of researching the BCI system is to provide a way for patients with neurological and motor system diseases to communicate with the outside world, allowing patients to control external devices with their own thinking and consciousness, and further improving the quality of life of patients. As the research on this technology gradually deepens, the brain-computer interface will play a greater application value in ...
