Embodiment Construction
[0020] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0021] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.
[0022] Visual evoked potential is when visible light stimulates the retina at an artificially coded frequency, and produces an EEG signal similar to the coded frequency in the visual cortex of the occipital lobe of the human brain. Taking the Steady State Visual Evoked Potential (SSVEP) as an example, when the visual stimulus is a steady 3.7-75Hz flicker, the visual cortex in the occipital lobe of the human brain can detect...

Description
technical field [0001] The present invention relates to an information interaction device, in particular to a navigation system and device based on a visually evoked potential brain-computer interface. Background technique [0002] Brain-computer interface is a means of communication that has made remarkable progress in brain science research in recent years. By encoding and decoding behavioral intentions in brain activities, brain-computer interfaces can establish direct communication and control channels between the brain and external devices. According to the different ways of collecting signals, brain-computer interfaces can be divided into two types: invasive and non-invasive. Non-invasive brain-computer interfaces are more widely used. Do more work. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggesti...
