For a better understanding of the present disclosure and to show how to realize the present disclosure, examples are herein described with reference to the attached drawings, wherein:
It should be noted that throughout the attached drawings, similar reference numerals and signs refer to corresponding parts.
The following detailed description is made with reference to the attached drawings, and the following detailed description is provided to facilitate comprehensive understanding of various exemplary embodiments of the present disclosure. The following description includes various details to facilitate understanding. However, these details are merely considered as examples, not for limiting the present disclosure. The words and phrases used in the following description are only used to enable a clear and consistent understanding of the present disclosure. In addition, for clarity and brevity, descriptions of well-known structures, functions, and configurations may be omitted. Those of ordinary skill in the art would realize that various changes and modifications can be made to the examples described in the present specification without departing from the gist and scope of the present disclosure.
As stated before, people have been increasingly using various kinds of audio/video playback devices in daily life. For example, people listen to audio programs or watch video programs to relax before falling asleep, and may fall asleep during listening or watching. Especially for some people who have difficulties in falling asleep, playing a video or audio program before falling asleep will make them relax and help them fall asleep. In this case, there may be situations where the listener or viewer has fallen asleep while the audio/video playback device is still playing. Usually, people will set the audio/video playback device to an automatic shutdown mode when they are sleepy and want to sleep. In the automatic shutdown mode, the audio/video playback device will automatically shut down after a predetermined time, and this can avoid the situation where the listener or viewer has fallen asleep and the audio/video playback device cannot be turned off.
However, in an existing automatic shutdown mode, when a predetermined time has passed, the audio/video playback device will immediately shut down, and the audio volume value or the brightness value of the playback screen will immediately drop to zero. This sudden change in the audio volume value or the brightness value of the playback screen may cause interference to the user who has fallen asleep or is about to fall asleep. The user may be awakened and unable to fall asleep or have to turn on the audio/video playback device again to get ready to fall asleep again. Therefore, this automatic shutdown mode is not friendly to users who have difficulties in falling asleep or who are easily awakened. These users cannot use this automatic shutdown mode of the audio/video playback device to help them fall asleep.
The technical solutions of the present disclosure provide a device or a method for automatically turning off an audio device or a video device by gradually changing the brightness value or the volume value to help users fall asleep. In one or more embodiments according to the present disclosure, the change of the brightness value or the volume value may be selected according to different situations. For example, a suitable brightness value or volume value change may be selected according to a user's sleep history data to maximize the help to sleep.
Next, the embodiments of the present disclosure will be described in detail with reference to the attached drawings.
The electronic device 100 may be used to implement various embodiments of the method according to the present disclosure. The electronic device 100 may comprise a processing subsystem 110, a memory subsystem 112, and a networking subsystem 114. The processing subsystem 110 comprises one or a plurality of devices configured to execute computing operations.

Furthermore, in some embodiments, the electronic device 100 may include one or more additional subsystems not shown in
The exemplary network environment 200 may comprise an AP 210 and one or a plurality of client devices 220A, 220B, and 220C (hereinafter, collectively referred to as client device 220 for simplicity). The electronic device 100 shown in

As shown in
According to another embodiment of the present disclosure, the request for entering the sleep mode may be received from a wearable device that monitors physiological parameters of a user. For example, the user can wear a bracelet that monitors the user's physiological parameters. When the bracelet detects that the user has not moved within a predetermined period of time, or the physiological parameters collected by the bracelet that monitors the user's physiological parameters indicate that the user may be about to fall asleep, the bracelet can send a request for entering the sleep mode to a device executing a method.
Returning to
In another embodiment according to the present disclosure, physiological parameter values of a user during the sleep mode are obtained as sleep history data from a wearable device that monitors the physiological parameters of the user. The expected time to fall asleep may be determined based on the sleep history data. For example, the sleep history data may include a plurality of recorded values of the time from sending a request for entering the sleep mode by the user to falling asleep. Exemplarily and not restrictively, the average value of the plurality of recorded values may be determined as the expected time to fall asleep. For example, if the sleep history data from a wearable device that monitors the physiological parameters of the user indicates that the user usually falls asleep about 30 minutes after requesting to enter the sleep mode, the expected time to fall asleep may be set to 30 minutes when the user requests to enter the sleep mode next time so as to better suit the user.
Back to
In 304, a decay type is selected. The decay type refers to the way in which the volume value and/or brightness value of the playback device is decreased to enter the shutdown state. According to one or more embodiments of the present disclosure, the decay types may include one or more of a linear decay, a parabolic decay, a Gauss decay, and an exponential decay. In the linear decay, the amount of decrease of the volume value and/or brightness value per unit time is the same. In the exponential decay, the volume value and/or brightness value decreases rapidly at the beginning and then slows down. In the Gauss decay, the volume value and/or brightness value decreases slowly at the beginning and then decreases rapidly. Those skilled in the art will understand that the decay types listed are only exemplary and not restrictive.
According to an embodiment of the present disclosure, the decay type may be selected according to user input. For example, the user may select a suitable decay type according to the user's experience on use.
In another embodiment according to the present disclosure, the decay type may be determined based on the sleep history data. For example, the sleep history data may include a plurality of recorded values of the time from sending a request for entering the sleep mode by the user to falling asleep when a certain decay type is used. Exemplarily and not restrictively, an average time to fall asleep may be determined corresponding to the used decay type. A short average time to fall asleep indicates that the user can fall asleep better under this decay type, and thus it is possible to select the decay type with the shortest average time to fall asleep for the user.
Returning to
The decay type can be expressed by a linear function, which can be represented by the following formula:
f(t)=Value1−m*t
where f(t) represents the brightness value or volume value that changes with time, Value1 represents the brightness value or volume value at the time a request for entering the sleep mode is made, t represents time, the coefficient m corresponds to the required amount of change per unit time of the brightness value and/or the volume value, and the coefficient m can be determined according to the decay type, expected time to fall asleep, and the volume value and/or the brightness value at the time the request for entering the sleep mode is made.
Those skilled in the art will understand that the schematic diagram of the decay type is only exemplary and not restrictive.
