For example, the method further comprises: activating the play mode of the sleep aiding device <NUM> in response to receiving the display and play instruction; and adjusting the play mode according to the display and play instruction, so that the play mode matches the physical sign data and the brainwave signal data of the user. For example, by using the method, the play content and the play volume may be adjusted according to the sleep-awake degree of the user. For example, as the user gradually enters into the deep sleep state from the awake state, by using the method, the volume may be gradually lowered and the play content may be switched, until the play mode is deactivated.

In some examples, the generating device <NUM> acquires the physical sign data and the brainwave signal data of the user, and compares and maps the data with a preset data table of respective stages of an awake state and a sleep state of a human body, so as to determine a current sleep-awake degree of the user (e.g., fully awake, shallow sleep, or deep sleep, etc.). For example, when the user's pulse data coincides with pre-stored pulse data when the human body enters deep sleep, and the user's brainwave signal data coincides with pre-stored brainwave signal data when the human body enters deep sleep, the generating device <NUM> determines that the user is in the deep sleep state.

It is worth noting that, the preset data table of respective stages of the awake state and the sleep state of the human body may be obtained in advance through experimental measurements and stored in a memory. For example, by monitoring sleep of a large number of volunteers, physical sign data and brainwave signal data of respective volunteers when they are in different sleep-awake degrees (e.g., fully awake, shallow sleep, or deep sleep) are collected, and the collected data is organized into a tabular form. By taking the pulse data and the brainwave signal data as an example, an exemplary table is shown below:.

Of course, it is also possible to collect the physical sign data and the brainwave signal data related to the user of the sleep aiding device in advance when the user is in different sleep-awake degrees, and then organize the collected data into a tabular form.

The generating device <NUM> generates the display and play instruction according to the current sleep-awake degree of the user. The display and play instruction may instruct the display content (e.g., projected content), image brightness, the play volume, play sound/music genre, and turning on or off of the display and/or play function. The sending device <NUM> sends the display and play instruction to the sleep aiding device <NUM>. Therefore, through the indication of the display and play instruction, both the display mode and the play mode of the sleep aiding device <NUM> may be matched with the current sleep-awake degree of the user.

In some examples, the sleep aiding device <NUM> may send current brightness information of a surrounding environment in which the user is located to the server <NUM>. The generating device <NUM> may determine an amount of brightness of the display image to be adjusted according to the current sleep-awake degree of the user and the current brightness information of the user's surrounding environment, and then generate the display and play instruction accordingly.

For example, the receiving device <NUM> and the sending device <NUM> may be integrated as a transceiving device, which may include, for example, a wireless transceiver or a network adapter, and the like.

In some embodiments of the present disclosure, the receiving device <NUM>, the generating device <NUM>, and the sending device <NUM> may include codes and programs stored in a memory; the processor may execute the codes and the programs to implement some or all of the functions of the receiving device <NUM>, the generating device <NUM> and the sending device <NUM> as described above.

The server <NUM> includes the receiving device <NUM>, configured to receive physical sign data and brainwave signal data of a user; the generating device <NUM>, configured to determine a sleep-awake degree of the user according to the physical sign data and the brainwave signal data, and generate a display and play instruction according to the sleep-awake degree of the user; and the sending device <NUM>, configured to send the display and play instruction. For example, the sleep aiding device <NUM> and the server <NUM> may communicate through a network <NUM>; or, the sleep aiding device <NUM> and the server <NUM> may directly communicate with each other.

<FIG> is a schematic diagram of the sleep aiding device <NUM> provided by an embodiment of the present disclosure. The physical-sign detecting part <NUM> is an arm-bearing physical-sign detecting part mounted on an outer edge of a rest appliance <NUM> (for example, a sofa or a bed). The brainwave detecting part <NUM> is provided in a pillow shape. The display and play part <NUM> is provided in the physical-sign detecting part <NUM>. The display and play part <NUM> is configured to project onto a projection plane <NUM>.

With reference to <FIG>, the physical-sign detecting part <NUM> includes a fixing sub-part <NUM> and a physical-sign detecting sub-part <NUM> (e.g., an armlet). The fixing sub-part <NUM> fixes the armlet itself, and fixes the arm-bearing physical-sign detecting part to the edge of the sofa or the bed. A sensor <NUM> is provided on the inner side of the physical-sign detecting sub-part <NUM>. A signal amplifier <NUM>, a signal transceiver <NUM> and a display device <NUM> of the display and play part <NUM> are all fixed to the physical-sign detecting part <NUM>.

With reference to <FIG>, the pillow apparatus <NUM> of the brainwave detecting part <NUM> is a headrest; the brainwave detecting sub-part <NUM> includes a frame <NUM> (for example, a head frame) and a brainwave detecting electrode <NUM> fixed onto the head frame. When the user is lying down, his/her head is laid on the headrest and the head frame is worn, so that the brainwave detecting electrode in the head frame is in contact with the user's scalp to acquire his/her brainwave signal data.

In summary, the sleep aiding device and the method thereof, the server and the method thereof, and the sleep aiding system provided by the embodiments of the present disclosure, are capable of automatically adjusting the display mode and the play mode according to changes in the sleep-awake degree of the user, so that both the display mode and the play mode match the user's current sleep-awake degree, to help the user fall asleep quickly, and improve the sleep quality.

In the present disclosure, terms such as "first", "second" and the like used in the present disclosure do not indicate any sequence, quantity or significance but only for distinguishing different constituent parts. Also, the terms such as "a," "an," or "the" etc., are not intended to limit the amount, but indicate the existence of at least one. The terms "comprises," "comprising," "includes," "including," etc., are intended to specify that the elements or the objects stated before these terms and encompass the elements or the objects and equivalents thereof listed after these terms, but do not preclude the other elements or objects.
