detailed description

The invention will be described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 , an embodiment of the present invention provides a playback control method for a mobile terminal, including:

S11. Acquire a physical parameter of the user.

S12. Perform playback control on the mobile terminal according to the physical parameter.

The playback control method for the mobile terminal provided by the embodiment of the present invention can acquire the user's The physical parameters, and the playback control of the mobile terminal according to the acquired physical parameters, so that the music or other programs played by the mobile terminal can be controlled and changed according to the user's physical state and feeling, so that the played content and The playback mode is more in line with the user's state and mood, thus greatly improving the user experience.

Specifically, in step S11, various types of sensors capable of sensing human body vitality parameters may be provided on the mobile terminal or an accessory such as a headset thereof, and the mobile terminal is set when the user holds the mobile terminal or uses the earphone to listen to the music program. Or the sensor on the headset can collect one or more of the user's physical parameters. For example, in an embodiment of the present invention, the user's physical parameters such as the user's heart rate and/or the user's body temperature may be acquired through an infrared sensing device on the earphone that is matched with the mobile terminal. The optical heart rate sensor built into the earphone measures the heart rate through the skin under the ear canal. The principle is similar to that of a finger heart rate monitor commonly used in hospitals. Heartbeat detection uses a common method to change the heart rate according to the blood volume of the capillaries as the heart beats.

Since the heart rate is closely related to the physical state and mood of the person, the physical state or mental state of the user can be determined according to the heart rate of the user, thereby selecting an appropriate playing program or playing form to improve the user experience.

For example, in an embodiment of the present invention, in order to prevent the user from wearing the earphone to listen to music and falling asleep, the user's hearing and sleep are affected. In step S12, the playing control of the mobile terminal according to the physical parameter may specifically include:

Determining, if the user heart rate is less than a resting threshold, whether the user heart rate is less than a sleep threshold; wherein the sleep threshold is less than the resting threshold;

In a case where the user's heart rate is less than the sleep threshold, the sound playback of the mobile terminal is stopped or the mobile terminal is muted.

It should be noted that the resting threshold refers to the heartbeat frequency in a quiet state in which a normal person is awake and inactive. The sleep threshold refers to the heartbeat frequency of a normal person entering a mild sleep state. In general, people who sleep The physiological indicators are relatively decreased, so the sleep threshold is also less than the resting threshold. When the user's heart rate is less than the resting threshold, the user may be gradually entering the sleep state, and when the user's heart rate is less than the sleep heart rate, the user has entered the sleep state. At this time, the sound playback of the mobile terminal is stopped or the mobile terminal is muted. Make the user sleep more peacefully.

In order to enable the user to play the user's physical state during the process of entering the sleep, the method further includes: after determining whether the user's heart rate is less than a sleep threshold, the method further includes:

Determining a change trend and a change rate of the user's heart rate if the user's heart rate is greater than or equal to the sleep threshold;

The volume of the mobile terminal is decreased when the trend of the heart rate of the user is decreased, and the rate of change of the user's heart rate is greater than a preset change threshold.

Among them, the change trend of the user's heart rate refers to whether the average heart rate of the user is higher or lower than the average heart rate in the previous statistical period, and the rate of change refers to the change speed of the user's heart rate. That is, the heartbeat value increased or decreased per unit time. Specifically, the change threshold refers to the number of times the average heart beats down per minute during normal sleep.

For example, suppose the resting threshold is 72 times / minute, the sleep threshold is 60 times / minute, the change threshold is 5 times / minute, take the average heart rate within the current 2 minutes and the average heart rate in the previous 2 minutes, if the current The user's heart rate is 64 times/min, between the resting threshold and the sleep threshold, and further determining the change trend and the change rate of the user's heart rate, if the average heart rate in the current 2 minutes is 66 times/minute, and the previous one The average heart rate within 2 minutes is 74 beats/min, that is, the change trend is reduced, and the change rate is 8 times/min, so that the volume of the mobile terminal can be appropriately lowered to accommodate the user entering sleep.

It should be noted that the parameters of the resting threshold, the sleep threshold, and the change threshold may be based on statistics on physiological parameters of the general population, but due to differences between the individual and the individual, the mobile terminal may be made before the formal use. Learning and adapting to the user's physical condition and signs, Thereby, various thresholds unique to the user are determined, thereby making the mobile terminal more accurate in judging whether the user is sleeping or not.

The above embodiment describes the use of the physical parameter of the user's heart rate to adjust the playback volume of the mobile terminal when the user sleeps, but the present invention is not limited thereto. In other embodiments of the present invention, other physical parameters collected by the sensor may also be utilized to implement playback control in other states of the user, such as volume control of the mobile terminal during running, and selection of a play program. To achieve the purpose, the playing control of the mobile terminal according to the physical parameter may include:

Establish a database of correspondence between music style and physical parameters;

The music whose music style corresponds to the physical parameters is played.

Music stored on a mobile terminal or music that is listened to online from the Internet will have some additional music information, such as singer, release time, style, genre, and so on. Among them, the music style can include: sadness, quietness, dance music, nostalgia, passion, classical, country and so on. People's heart rate and body temperature will be different under different sports conditions or emotions. In order to match the state at that time, people prefer to listen to programs of different musical styles. Therefore, the physical parameters such as heart rate and body temperature are matched with the music style. When the sensor monitors the corresponding physical parameters, the corresponding program is called from the database, which avoids the user's cumbersome search and switching, greatly improving the user experience. .

The playback control method for the mobile terminal provided by the present invention will be described in detail below through specific embodiments.

As shown in FIG. 2, in this embodiment, the play control is implemented by the earphones matched by the mobile terminal. Related devices include: a detection module and a control module. The detecting module is implemented by attaching a photoelectric sensor 101 to the outside of the earphone matched with the mobile terminal, and the control module has a built-in control chip 102 through the earphone. Among them, the earphone can be either a wired earphone or a bluetooth earphone.

The detection module is configured to collect the heartbeat information of the user. The earphones have an optical heart rate sensor that measures the heart rate through the skin under the ear canal. The principle is similar to that of a finger heart rate meter commonly used in hospitals. Heartbeat detection is a common way to change this physiology according to the blood volume of the capillaries as the heart beats. Features, using the photoelectric conversion principle to complete the measurement of heart rate.

The control module, the built-in control chip of the earphone, is responsible for processing the collected pulse signal, calculating the heart rate, analyzing the heart rate data, and determining the command for sending the volume adjustment according to the preset strategy to the terminal (smartphone or other playback device) connected to the earphone.

According to the physiological characteristics of the blood volume of the capillaries changing with the heart beat, the heart rate can be measured by the photoelectric conversion principle. The flow of data in the detection module and the control module during heart rate detection can be shown in Figure 3.

A certain working voltage is applied to both ends of the infrared light sensor 201, and the output voltage thereof changes according to the change of the illumination intensity of the infrared light after receiving the blood vessel reflection, thereby generating a voltage signal. The voltage signal is filtered by a low pass filter 202 to filter out the residual signal. The signal amplifier 203 amplifies the signal and converts the waveform to obtain a pulse signal. The pulse signal is input to the control chip 204, and the control chip 204 combines the clock to calculate the pulse interval to obtain more accurate heart rate data.

As shown in Figure 4, the volume adjustment operation of the playback process is as follows:

The device starts first into the calibration phase:

S301. The sensor in the detection module detects heartbeat information and sends the information to the control module.

S302. The control module receives heartbeat data detected by the sensor.

S303. The control module calculates a frequency of the heartbeat. Specifically, the frequency of the heartbeat is calculated from the average interval of heartbeats detected within a predetermined period of time (for example, within 20 seconds).

In S304, it is judged whether or not the calibration is currently completed. If the calibration is not completed, the process returns to S301, and the process ends.

Specifically, the criterion for judging whether the calibration is finished is that the heartbeat conforms to the normal resting heart rate range and lasts for more than 30 seconds. Or the calibration time is more than 5 minutes and forced to end. The current heart rate is obtained as the resting heart rate threshold after the calibration is completed. Continue to monitor your heart rate.

S305. Calculate a resting threshold.

S306. The sensor in the detection module detects heartbeat information and sends the information to the control module.

S307. The control module receives the heartbeat data detected by the sensor.

S308. The control module calculates a frequency of the heartbeat and a curve of the time period;
