The wearable device 110 and the mobile terminal 120 can communicate with each other through a wireless network and transmit signals and data by using a wireless communication method, such as Bluetooth, Zigbee, or WIFI. In an actual implementation, the mobile terminal 120 can be, but is not limited to, a smart phone or a tablet, and the wearable device 110 can be, but is not limited to, a head mounted wear device.

In this embodiment, the smart sleep assisting method performed by the smart sleep assisting system 100 may include the following steps: the wearable device is worn on the user's head and activated (step 220); the mobile terminal is connected to the wearable device ( Step 230); the touch display module displays the application page and receives the set time data (step 240); the brain wave detection module continuously detects the user's brain wave signal and transmits the signal to the transmission module (step 250) The transmitting module receives and transmits the brain wave signal of the user to the mobile terminal (step 260); the memory module continuously receives and stores the brain wave signal from the wearing device, wherein each brain wave signal corresponds to an additional time stamp ( Step 270); the second processing module analyzes each brain wave signal received by the memory module to determine whether the user is in a sleep state or an awake state (step 280); and when the second processing module determines that the user is in a sleep state And outputting a sleep signal to the transmission module (step 290); when the second processing module determines that the user is in the awake state, according to the currently analyzed brain wave signal Adding a time stamp and setting time data, outputting a situation signal to the transmission module, and transmitting a reminder signal to the touch display module display (step 300); when the transmission module receives the situation signal, the first processing module is based on The context signal controls the playing module to play the corresponding sleep assisting sound signal (step 310); when the transmitting module receives the sleep signal, the heartbeat measuring module measures the heart rate variability (step 320); when the heart rate variability is sympathetic When the ratio of the neural and parasympathetic activity is greater than a certain value, the playback module is controlled to play a relaxed sound signal (step 330).

In step 220, the wearable device 110 can be worn on the user's head and powered on (ie, activated) in a helmet-style manner. Next, the mobile terminal 120 can open a wireless network connection with the wearable device 110 between or after the applications it has (ie, step 230). In step 240, a page is displayed on the touch display module 122 of the mobile terminal 120 to enable the user to input the expected sleep time (ie, the touch display module) through the touch display module 122. 122 receives the set time data input from the user).

After the wearable device 110 is activated, the brain wave detecting module 112 can continuously detect the brain wave signal of the user and transmit the signal to the transmitting module 111 (ie, step 250), so that the transmitting module 111 can receive and transmit the signal. The brain wave signal is transmitted to the mobile terminal 120 (ie, step 260). Therefore, the memory module 124 can continuously receive and store brainwave signals from the wearable device 110, wherein each brainwave signal can correspond to an additional time stamp, and the time stamp can include the brainwave received by the memory module 124. The time of the signal (ie step 270).

In step 280, the second processing module 126 can analyze each brain wave signal received by the memory module 124 to determine whether the user is in a sleep state or an awake state. In more detail, when the user is in a sleep state, the brain wave signal may include a delta wave and/or a θ wave; when the user is in an awake state, the brain wave signal may include an alpha wave and/or a beta wave, and thus, when When the brain wave signal analyzed by the second processing module 126 includes the delta wave and/or the θ wave, the user can be judged to be in a sleep state; when the brain wave signal analyzed by the second processing module 126 includes the alpha wave and / or β wave, it can be judged that the user is awake.

And transmitting the reminder signal to the touch display module 122 for display; when the transmission module 111 receives the context signal, the first processing module 115 controls the play module 114 to play the corresponding sleep assist sound signal according to the received context signal. In more detail, when the second processing module 126 determines that the user is in the awake state, the second processing module 126 compares the time stamp corresponding to the currently analyzed brain wave signal (ie, the memory module 124 receives the time). The time of the brain wave signal is set with the time when the user sets the expected sleep time (ie, the touch display module 122 receives the set time data input from the user), and according to the time included in the time label and the time the user is expected to sleep. The time between the different distance signals is output to the transmission module 111, and the different warning signals are transmitted to the touch display module 122 for display, so that the first processing module 115 controls the playing module 114 according to different context signals. Play the corresponding sleep assist sound signal. For example, when the time interval between the time included in the time stamp and the time when the user sets the expected sleep time is one and a half hours, the second processing module 126 outputs the preliminary sleep signal to the transmission module 111 to make the first processing. The module 115 controls the playing module 114 to play the corresponding sleep assisting sound signal according to the preliminary sleeping signal, and the second processing module 126 transmits the corresponding reminding signal to the touch display module 122 to display the words "preparing to sleep". To remind the user to start sorting things done at hand to help fall asleep at the estimated time of sleep; when the time interval between the time stamp and the time the user sets the expected sleep time is half an hour, the second treatment The module 126 outputs the sleep signal to the transmission module 111, so that the first processing module 115 controls the playing module 114 to play the corresponding sleep assisting sound signal according to the bed-sleep signal, and the second processing module 126 transmits the corresponding reminder. The signal is applied to the touch display module 122 to display a text such as "go to bed" to remind the user that they can proceed to pick up the hand Things ready for bed.

The first processing module 115 can include a context database 50, and the context database 50 stores various sound signals including sleep auxiliary sound signals corresponding to various different context signals and relaxed sound signals corresponding to the sleep signals. Therefore, the first processing module 115 can search for the corresponding sound signal in the context database 50 after receiving the relevant signal, thereby controlling the playing module 114 to play the sound signal it finds.

In addition, because you have good sleep quality and enough sleep time, users need to know how their sleep is going. After that, they can know when they should sleep and when they can expect to wake up. According to your sleep process, choose your own sleep strategy so that you can have good sleep quality and enough sleep time. In this embodiment, the brain wave detecting module 112 continuously detects the brain wave signal of the user and transmits it to the transmitting module 111, and the transmitting module 111 continues for the user to be in a sleeping state or an awake state. Receiving and transmitting the brainwave signal of the user to the memory module 124 for storage, therefore, the mobile terminal 120 can collect all the data (each of which the user uses the smart sleep assisting system 100 to perform the smart sleep assisting method (including: expected to sleep) Time, brainwave signals and their associated time stamps, sleep signals and the time and context signals they generate and the time they are generated), which in turn analyzes the average sleep cycle of the user and analyzes the user based on brainwave signals in the sleeping state. The quality of sleep, and further from the consultation database (not drawn) to find the corresponding recommendations to provide users with advice on improving sleep quality. When the touch display module 122 displays a page for providing a user to input the time when the user intends to sleep, the information of the page may include sleep cycle data and suggestion materials to provide a reference for the user to input the estimated sleep time.

In the embodiment, the wearable device 110 further includes a sound receiving module 116 for receiving a noise signal, so that the first processing module 115 analyzes the noise signal and then controls the playing module 114 to play and An anti-noise signal that cancels the noise signals. The noise signal may be, but is not limited to, a sound signal that interferes with the user's sleep or sleep, such as the snoring of another person. Through the design of the sound module 116, the user can be free from external noise signals.

In this embodiment, the wearable device 110 can further include a camera module 117 and an attitude module 118. The posture module 118 can be used to obtain an attitude signal and transmitted to the first processing module 115. The camera module 117 can be used as the first When the processing module 115 determines that the change of the attitude signal exceeds the first expected value and the transmission module 111 receives the slow wave signal from the mobile terminal 120, the environment image is captured, and the environmental image is transmitted to the first processing module 115. After analyzing the environmental image, the first processing module 115 controls the playing module 114 to play the corresponding guiding sound signal according to the context database 50. In more detail, since the wearable device 110 is worn by the user, the wearable device 110 can continuously obtain the posture of the user by the posture module 118, and generate a posture signal, wherein the posture module 118 has a gyroscope and a gyroscope. The sensed output is related to the attitude data of each axis in the coordinate system itself, and when the posture of the user changes, the amount of change of the posture data of any axis sensed by the gyroscope exceeds the first expected value (for example, the change from lying down) In the sitting or standing position, and the user's brain wave signal is a θ wave (ie, the second processing module 126 immediately analyzes the brain wave signal as a θ wave and outputs a slow wave signal to the transmission module 111), The camera module 117 can perform an environment image, and analyze the environment image through the first processing module 115 to obtain the state of the surrounding environment, and then according to the state of the surrounding environment. The context database 50 is searched, and since the context database 50 includes various states corresponding to different states, the first processing module 115 can use the contextual resource. The library 50 finds the corresponding instruction, and then controls the playing module 114 to play the corresponding guiding sound signal (ie, the corresponding instruction) to guide the user to restore the original posture of the sleeping state. The operating principle is similar to the usage principle of the SIRI, and the difference is only The input of the present invention is an environmental image captured by the camera module 117 rather than a voice input. Among them, the first expected value can be adjusted according to actual needs.
