[0002] Functional near-infrared spectroscopy is a technology for evaluating brain function. It uses near-infrared spectroscopy to measure the content of oxygenated hemoglobin and deoxygenated hemoglobin in the cerebral cortex in real time, and has advantages such as a wide range of applications, insensitivity to motion artifacts, good electromagnetic compatibility, high spatio-temporal resolution, and can be used in natural situations. These advantages make it suitable for evaluating the brain function and diseases of adults, such as schizophrenia and psychological disorders, etc.

[0003] In order to better induce and capture the activity patterns of the brain in a specific task state, so that researchers or doctors can observe and analyze the blood oxygen changes and metabolism of the brain when performing specific tasks, patients need to look at icons during the process of near-infrared monitoring of brain function.
