Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a method, apparatus, wearable device, and medium for determining calorie consumption. Background Technology

[0002] As users pursue personalized experiences, wearable devices are also diversifying their functions. Fitness tracking is a standard feature of wearable devices, allowing users to calculate calories burned based on their posture and motion algorithms, thus aiding in training. Currently, calorie expenditure is primarily measured using a G-sensor to detect posture along three axes. However, as exercise progresses, the user's body temperature changes, and calorie expenditure fluctuates accordingly. If calorie expenditure only considers posture-detected motion parameters without taking into account body temperature variations, the calculated calorie expenditure will be inaccurate.

[0003] For user body temperature detection, wearable devices such as smartwatches typically integrate body temperature monitoring functions to collect user body temperature parameters. However, the body temperature parameters detected by smartwatches are the user's surface temperature. Since surface temperature is greatly affected by external environment, sweat, etc., the measurement of calorie consumption based on surface temperature is not accurate, which reduces the user's experience.

[0004] Therefore, improving the accuracy of calorie consumption data in wearable devices is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0025] Preferably, it further includes:

[0040] To more clearly illustrate the embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0043] Figure 3 This is a structural diagram of a wearable device provided in an embodiment of the present invention. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present invention.

[0045] The core of this invention is to provide a method, apparatus, wearable device, and medium for determining calorie consumption, thereby improving the accuracy of calorie consumption in wearable devices.

[0046] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] It should be noted that the method for determining calorie consumption provided by this invention is applicable to wearable devices, such as headphones, true wireless stereo (TWS) headphones, smart bracelets, smart sports watches, etc.

[0048] Figure 1 A flowchart illustrating a method for determining calorie consumption provided in an embodiment of the present invention is shown below. Figure 1 As shown, applied to wearable devices, the method includes:

[0049] S11: Acquire the temperature value of the ear cavity collected by the earphone, wherein the earphone has a temperature sensing probe for use in the ear cavity.

[0050] It is understood that the headphones in this embodiment can be bone conduction headphones, in-ear headphones, and semi-in-ear headphones. In-ear and semi-in-ear headphones can collect the temperature value of the ear cavity, and bone conduction headphones have a temperature sensing probe built into the ear cavity, which can also collect the temperature value of the ear cavity.

[0051] The earphones are placed inside the ear canal. Because the ear canal is less exposed to the external environment and avoids contact with sweat, the temperature inside the ear canal is less affected by the external environment and sweat compared to the temperature value collected by the temperature sensor on the body surface. This makes the determination of calorie consumption more accurate. The earphones have a temperature sensor inside that can collect temperature values ​​from the ear canal.

[0052] S12: Acquire the attitude values ​​collected by the attitude sensor.

[0053] Specifically, the wearable device acquires the attitude values ​​collected by the attitude sensor. This wearable device can be headphones or other wearable devices, such as a smartwatch. When using headphones (as described in step S11), the headphones have an internal attitude sensor and a temperature probe to collect attitude values ​​and ear canal temperature values. When using other wearable devices, these devices need to have an internal attitude sensor to collect attitude values. Finally, the temperature values ​​from step S11 and the attitude values ​​from this embodiment are applied to the motion algorithm to obtain calorie consumption.

[0054] The attitude sensor is a high-performance three-dimensional motion attitude measurement system based on Microelectro Mechanical Systems (MEMS) technology. It includes auxiliary motion sensors such as a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass. It outputs calibrated angular velocity, acceleration, magnetic data, etc. through embedded low-power random access memory (RAM). It performs motion attitude measurement through quaternion-based sensor data algorithms and outputs zero-drift three-dimensional attitude data in real time, expressed in quaternions, Euler angles, etc.

[0055] S13: Determine calorie consumption based on posture and temperature values.

[0056] After obtaining the attitude value in step S12, the calorie consumption is determined based on the attitude value and temperature value. Specifically, when the wearable device is an earphone, the calorie consumption can be determined within the earphone. In this case, it can be announced via voice or the data can be transmitted to a terminal device for display. This invention does not impose any specific limitations.

[0057] When the wearable device is something other than headphones, the posture values ​​collected by the device itself and the temperature values ​​collected by the headphones need to be analyzed and applied to the motion algorithm to determine calorie consumption. In this case, the temperature values ​​collected by the headphones need to be transmitted to the wearable device, which can be done via Bluetooth. There are two Bluetooth connection methods: classic Bluetooth and Bluetooth Low Energy. This invention does not specifically limit which Bluetooth connection method is used, as long as the temperature values ​​can be accurately and timely transmitted to the wearable device.

[0058] This invention provides a method for determining calorie consumption, applied to wearable devices, comprising: acquiring ear canal temperature values ​​collected by earphones, wherein the earphones have a temperature sensing probe for embedding in the ear canal; acquiring posture values ​​collected by a posture sensor; and determining calorie consumption based on the posture values ​​and temperature values. This method uses ear canal temperature values ​​collected by earphones, ensuring that the collected temperature values ​​do not directly contact the external environment and also avoid contact with sweat, thus minimizing the impact of external environment and sweat. Furthermore, it determines calorie consumption based on temperature and posture values, avoiding the inaccuracies of existing methods that rely solely on posture values, or the inaccuracies caused by relying on both posture and body surface temperature values ​​due to the significant influence of external environment or sweat during body surface temperature acquisition. This improves the accuracy of calorie consumption calculations in wearable devices, further enhancing the user experience.

[0059] Based on the above embodiments, when the wearable device is a wearable device other than headphones, step S11 of obtaining the ear canal temperature value collected by the headphones includes:

[0060] Obtain the user's control commands and establish a Bluetooth connection between the headset and the wearable device based on the control commands;

[0061] The temperature value is obtained from the headphones via Bluetooth connection.

[0062] The headphones collect temperature values ​​after establishing a Bluetooth connection.

[0063] Understandably, when the wearable device is something other than headphones, the headphones collect temperature data, while the wearable device collects posture data. To obtain real-time calorie consumption data, the temperature data needs to be acquired in real time. The headphones and wearable device connect via Bluetooth. If the user wants to view calorie consumption during exercise, the Bluetooth connection only needs to remain active during the user's workout. Alternatively, the Bluetooth connection between the headphones and wearable device can remain continuous, only collecting temperature data during the user's workout to determine calorie consumption based on the temperature and posture data.

[0064] To reduce the power consumption of wearable devices, a Bluetooth connection can be established during user activity to collect ear canal temperature data. Therefore, it is necessary to obtain user control commands and establish a Bluetooth connection between the headphones and the wearable device based on these commands.

[0065] The user's control command can be either a command received by the headset that actively sends a request to the wearable device, or a command received by the wearable device that actively sends a connection request to the headset. This embodiment does not make any specific limitations, as long as a Bluetooth connection is established between the headset and the wearable device according to the user's control command.

[0066] The wearable device acquires temperature values ​​collected by the earphone via Bluetooth connection. After establishing a Bluetooth connection, the earphone collects the temperature value of the ear canal. Bluetooth connection methods include single-mode and dual-mode. Single-mode uses only Bluetooth Low Energy, while dual-mode has two built-in Bluetooth versions, running two separate protocol stacks, supporting both classic Bluetooth and Bluetooth Low Energy. This invention does not impose any specific limitations on this.

[0067] The headset establishes a Bluetooth connection with the wearable device based on the user's control commands. When the headset receives a command and actively sends a request to the wearable device, it needs to send a broadcast event to the wearable device to allow the connection, thus establishing a Bluetooth connection. After the connection is established, the headset begins to collect the temperature value of the ear canal. When the wearable device receives a command and actively sends a connection request to the headset, it sends a broadcast event to allow the headset to connect, thereby establishing a Bluetooth connection and notifying the headset to collect the temperature value of the ear canal.

[0068] This embodiment provides a method for obtaining user control commands and establishing a Bluetooth connection between the headphones and the wearable device when the wearable device is other than headphones. Temperature values ​​collected by the headphones are then acquired via Bluetooth. This saves power consumption for both the wearable device and headphones, extends their battery life, and improves the user experience.

[0069] Based on the above embodiments, the user's control commands can be received at the headset or at the wearable device. Therefore, the user's control commands include at least one of the following:

[0070] Commands generated by the user touching the interface of the wearable device;

[0071] Instructions generated based on detected user motion parameters;

[0072] Instructions generated from the user's voice information when preset voice conditions are met.

[0073] Specifically, when the user's control command is a command received by the wearable device, it can be a command generated by the user touching the interface of the wearable device, a command automatically generated based on the detected user's motion parameters, that is, a control command that is automatically activated when the device senses the user's current motion state based on changes in the user's posture value, or a command generated by the user based on the button settings of the wearable device, etc.

[0074] When the user's control command is received by the headset, the command can be generated based on the user's voice information, provided that the voice information meets preset voice conditions. These preset voice conditions can be keyword information; if the user's voice information contains keyword information, it indicates that the preset voice conditions are met and the command can be used as the user's control command. For example, if the voice information is "Turn on sports mode," and its keyword information is "turn on" and "sports," it can be used as a command to establish a Bluetooth connection. The keyword information can be one or more words, and there are no specific restrictions on language, etc.

[0075] The user control commands provided in this embodiment of the invention include at least one of the following: commands generated by the user touching the interface of the wearable device; commands generated based on detected user motion parameters; and commands generated by the user's voice information when preset voice conditions are met. Different motion commands are used to meet the needs of users in different motion scenarios, improve the user experience, and facilitate subsequent Bluetooth connection establishment between headphones and the wearable device.

[0076] Based on the above embodiments, the method further includes:

[0077] Obtain the raw temperature value of the ear canal collected by the headphones;

[0078] When the original temperature value is within the preset temperature range, the original temperature value is used as the temperature value.

[0079] When the original temperature value exceeds the preset temperature range, the original temperature value within the preset temperature range is selected as the temperature value.

[0080] Specifically, when the headphones collect the temperature value of the ear canal, the temperature value may suddenly drop or rise under different sports scenarios or complex environments, and then return to normal in the next temperature value. At this time, it is necessary to filter the temperature value and discard the abnormal temperature value. Therefore, it is necessary to obtain the original temperature value of the ear canal collected by the headphones. When the original temperature value is within the preset temperature range, the original temperature value is used as the temperature value. When the original temperature value exceeds the preset temperature range, the original temperature value within the preset temperature range is selected as the temperature value and transmitted to the wearable device.

[0081] In addition, the collected temperature values ​​can be set according to the pre-set initialization parameters, such as the collection frequency, the accuracy of the collected temperature values, or the number of harmonics and the number of filtering layers, etc. This embodiment does not make specific limitations.

[0082] This invention provides a method for acquiring the raw temperature value of the ear canal collected by an earphone. When the raw temperature value is within a preset temperature range, it is used as the actual temperature value. When the raw temperature value exceeds the preset temperature range, the raw temperature value within the preset temperature range is selected as the actual temperature value. Abnormal temperature values ​​are filtered out to ensure that the collected temperature values ​​are normal, thus making the subsequent calorie consumption data more accurate.

[0083] Based on the above embodiments, after obtaining the attitude values ​​collected by the attitude sensor in step S12, the method further includes:

[0084] Acquire the body surface temperature value collected by the temperature sensor;

[0085] Calorie consumption is determined based on body surface temperature, body temperature, and posture.

[0086] Specifically, the body surface temperature value collected by the temperature sensor inside the wearable device is used for calibration and compensation with the ear canal temperature value collected by the headphones. This is based on the data obtained through experiments regarding the mapping relationship between body surface temperature value and temperature value. Then, the body surface temperature value, temperature value, and posture value are applied to the motion algorithm to obtain calorie consumption.

[0087] It is understood that the motion algorithm mentioned in the embodiments of the present invention is not limited to a specific algorithm, as long as parameters such as body surface temperature value, temperature value and posture value can be input into the motion algorithm to obtain calorie consumption.

[0088] This embodiment provides a method for determining calorie consumption based on body surface temperature, body temperature, and posture. It also provides a reference for collecting ear cavity temperature values, making the obtained calorie consumption data more accurate.

[0089] Based on the above embodiments, and considering user health monitoring, the method further includes:

[0090] When the temperature value meets the first preset condition, the first prompt message is output, wherein the first preset condition is that the temperature value is greater than the first threshold within a preset time.

[0091] When the temperature value meets the second preset condition, the second prompt message is output. The second preset condition is that the temperature value is less than the second threshold within a preset time, and the first threshold is greater than the second threshold.

[0092] Specifically, excessively high or low temperatures during exercise can negatively impact a user's health. Therefore, when the collected temperature value meets a first preset condition, a first prompt message is output, whereby the temperature remains above a first threshold for a preset time period. When the collected temperature value meets a second preset condition, a second prompt message is output, whereby the temperature remains below a second threshold for a preset time period, and the first threshold is greater than the second threshold.

[0093] The first alert is issued when the user's temperature is too high, indicating overheating and requiring the user to adjust their exercise intensity. The second alert is issued when the user's temperature is too low, indicating hypothermia and requiring immediate cessation of exercise and monitoring of their physical condition.

[0094] The first and second prompts can be the same or different. In a preferred embodiment, the first and second prompts are different, especially in cases of hypothermia. In the initial mild to moderate hypothermia stages, individuals with hypothermia can still improve their condition by generating their own heat. However, if this is not addressed in the first two stages and progresses to severe hypothermia, the individual can no longer generate enough heat to survive, placing them in an extremely dangerous situation that could even lead to death. In this case, the second prompt needs to be sent more frequently than the first. Wearable devices can even automatically call for appropriate assistance in more severe situations based on the second prompt, using a positioning device.

[0095] The first and second notification messages can be displayed via pop-up windows on the wearable device's interface, vibration via the device's vibration module, or flashing on the interface, among other methods. No specific limitations are made regarding the frequency, period, or stopping method of the notifications. The notifications can be stopped by the user touching the interface after receiving the message, by voice communication, or based on the user's current motion parameters.

[0096] For example, the normal human body temperature ranges from 35℃ to 39℃. If the temperature value is consistently above the first threshold (39℃) within a preset time, it indicates that the user's current temperature is in a state of high fever. If the temperature value is consistently below the second threshold (35℃) within the preset time, it indicates that the user's current temperature is in a state of hypothermia. Regardless of whether the user is in a state of high fever or hypothermia, a warning will be issued to remind them not to overexert themselves to prevent harm to their health.

[0097] In addition, to facilitate users' access to and viewing of temperature changes during exercise, the collected temperature values ​​and their corresponding time can be plotted to generate a curve and displayed on the wearable device's interface. When the wearable device receives the ear canal temperature value collected by the earphone, it needs to add a timestamp to the temperature value, giving it a time attribute and allowing for more flexible use of the data to obtain the corresponding change curve.

[0098] The present invention provides that when the temperature value meets a first preset condition, a first prompt message is output, wherein the first preset condition is that the temperature value is greater than a first threshold within a preset time; when the temperature value meets a second preset condition, a second prompt message is output, wherein the second preset condition is that the temperature value is less than a second threshold within a preset time, and the first threshold is greater than the second threshold, which facilitates monitoring the user's health status and improves the user experience.

[0099] Based on the above embodiments, when the first or second prompt message is output, if the user's current movement is too vigorous or not sensitive enough to perceive the prompt from the wearable device, the method further includes:

[0100] The first and second prompt messages are sent to the headset for notification.

[0101] The first and second prompt messages are sent to the earpiece to provide prompts to the user via voice. It should be noted that in this embodiment, the first and second prompt messages will not appear simultaneously during the user's movement; this embodiment simply sends the first and second prompt messages to the earpiece according to the prompting method.

[0102] The present invention provides a method for sending first and second prompt messages to headphones to provide prompts, further instructing users on the intensity of their exercise and preventing overexertion from harming their health.

[0103] In one preferred embodiment, parameters such as the user's temperature and posture during exercise can be transmitted to a terminal device. The terminal device's comprehensive parameters are then used for health monitoring, allowing the user to view their health data. Data can be transmitted in real-time or after the user finishes exercising; this invention is not specifically limited. During real-time transmission, a Bluetooth dual-mode connection is initiated. This can involve the headphones and wearable device establishing a Bluetooth connection using one protocol, while the wearable device and terminal device establish a Bluetooth connection using another protocol, or the wearable device and terminal device establishing a Wi-Fi connection for transmission.

[0104] The present invention provides a method for transmitting data to a terminal device, which facilitates users to view their own health status, ensures users' physical health, and further enhances the user experience.

It then determines calorie consumption based on the temperature and posture values, avoiding the inaccuracies of existing methods that rely solely on posture values, or the inaccuracies caused by relying on both posture and body surface temperature values ​​due to the significant influence of external environment or sweat during body surface temperature acquisition. This improves the accuracy of calorie consumption determination in wearable devices and further enhances the user experience.
