Next, please refer to FIG. 10, which is a flowchart of a method for guiding brain waves in an embodiment of the present invention. The method includes the following steps: (S100) measuring a first brain wave signal of the wearer; (S200) executing a predetermined stimulation mode to provide an initial stimulation signal with stimulating effect; (S300) measuring the wearer's A second brain wave signal; (S400) According to the first brain wave signal and the second brain wave signal, obtain a brain wave change degree; (S500) According to the brain wave change degree and the third brain wave signal currently obtained , Corresponding to provide a guided stimulation signal to influence the wearer’s current brain waves.

In the embodiment of FIG. 10, the current brain wave changes degree of the wearer is first measured when the wearer is subjected to a certain degree of external stimulation. Based on this pre-test, the current brain wave state of the wearer can be determined In other words, it is possible to understand the extent to which the wearer can be guided at the moment to determine which guided stimulation mode to guide the wearer.

Based on the type of dominant brain wave (α, β, δ, θ), it can correspond to different states of consciousness. When alpha wave is dominant, it represents a state of bridge consciousness that is between waking and relaxed; when beta wave is dominant, it represents a state of conscious consciousness. This type of state usually occurs in a state of anxiety, thinking, or mental concentration while waking. Brain waves; when delta waves are dominant, it means that you are in an unconscious state, and this type of brain waves usually appear during non-rapid eye movement sleep; when theta waves are dominant, it means you are in a subconscious state, usually during deep dreaming or deep meditation This type of brain wave appears.

Accordingly, after the difficulty of guiding the brain waves is judged by first giving the stimulus, the wearer can be given a better stimulation mode to reach the preset guiding target, and the guiding efficiency can be improved.

Further, the predetermined stimulation mode and the guided stimulation signal provide a corresponding predetermined acousto-optic test mode to the wearer, and the predetermined acousto-optic test mode includes providing light parameters and the frequency difference between the left and right ears in a specific time period. The change. The changes in the light parameters and the frequency difference between the left and right ears include at least the change sequence of the light from reddish light, yellowish, greenish to blue light, and the reverse change sequence, or the change of the left and right ear frequency difference from 12 Hz to 2 Hz. The order and its reverse change order.

Among them, the change of high frequency frequency difference corresponds to the change of each ear between 200~210Hz (but the frequency difference is gradually adjusted from 12 Hz to 2Hz or the reverse order is gradually adjusted), and the frequency difference change of low frequency is for example the change of the sound frequency Between 170~173Hz (but the frequency difference is gradually adjusted from 12 Hz to 2Hz or the reverse order is gradually adjusted), there is a better effect. The light changes are divided into orange (reddish) corresponding to the refreshing state of shallow consciousness, orange (yellow) corresponding to the subconscious relaxed state, blue-green (green) corresponding to the light sleep guide, and the corresponding deep sleep guide Blue-green (blueish), according to the predetermined acousto-optic test mode, the light stimulus is gradually given from the current measured brain wave state, and the light is gradually changed to the target state based on the target state of the predetermined guidance The light should be given.

Taking the example of guiding the wearer to sleep, the brain wave changes corresponding to the smooth sleep state of consciousness are in order of β wave, α wave, θ wave, and δ wave. If the wearer’s brainwave changes are normal (that is, it is not difficult to be guided), and the third brainwave signal is α brainwave, that is, when the corresponding current state of consciousness is the bridge state of consciousness, then the control mode is set Group 50 controls the light parameters given within a certain period of time (for example, 5 minutes, 10 minutes) and the change in the frequency difference between the left and right ears from the alpha wave frequency band to the θ wave frequency band. For example, the frequency of light flashes per second changes from 10 Hz to 5 Hz. , And/or the frequency difference between the left and right ears changes from 10Hz to 5Hz.

Accordingly, the head-mounted device HD of this embodiment can guide the wearer's brain waves by light and sound, and assist the wearer to enter a specific state of consciousness (such as light sleep, deep sleep, etc.). It helps the wearer to enter the sleep phase faster, and thus achieves a better rest effect; in addition, by using the headset HD to sense the wearer’s brain waves in real time, it can determine where the wearer is currently A state of consciousness, which in turn leads to a state of consciousness toward deep sleep, thereby improving the wearer's sleep quality.

Correspondingly, in addition to guiding the wearer to a deep sleep state of consciousness, it can also be operated in the reverse direction to make the wearer tend to a waking state of consciousness, which can be used as a wake-up function.

Accordingly, the control module 50 of the head-mounted device HD in the embodiment of the present invention can be based on the first brain wave signal S20 received from the brain wave detection module 20, and based on the brain wave guide The module 30 is operated in a predetermined stimulus mode, and the control module 50 calculates a degree of brain wave change obtained from the signal returned by the brain wave detection module 20, so that the brain wave guides the module 30 Provide a guided stimulation signal. According to the current brainwave conditions of different wearers, a better guidance mode can be applied to improve the guidance efficiency.
