Description

Wearable devices and their tapping detection methods [Technical Field]

[0001] This application relates to the technical field of wearable devices, specifically to a method for detecting tapping on a wearable device and a wearable device itself. [Background Technology]

[0002] For wearable devices, tapping is a common interaction, and the device can execute corresponding control commands when it detects a tapping action. In related technologies, wearable devices typically include a detection module that detects tapping by detecting the vibration waveform generated by the tapping action. To more accurately detect the vibration waveform, a higher detection frequency is usually required for the detection module. However, prolonged high-frequency detection leads to significant power consumption. Therefore, how to perform accurate tapping detection with lower power consumption has become a pressing technical problem.

[0003] [Summary of the Invention]

[0004] This application provides a tapping detection method for a wearable device. The method includes: controlling a detection module to operate at a first detection frequency to acquire first kinematic parameters of the wearable device; responding to the first kinematic parameters satisfying a preset wake-up condition, controlling the detection module to operate at a second detection frequency to acquire second kinematic parameters of the wearable device, wherein the second detection frequency is greater than the first detection frequency, and the second kinematic parameters and the first kinematic parameters are parameters of the same type, wherein the wake-up condition is set according to the wearable device's initial kinematic response to a single tapping action; and responding to the second kinematic parameters satisfying a preset tapping judgment condition, generating a corresponding control command, wherein the tapping judgment condition is set according to the wearable device's subsequent kinematic response to a single tapping action.

[0005] In some embodiments, the wake-up condition includes: the rate of change of the first kinematic parameter over time reaches a first preset threshold, wherein the first preset threshold is a positive value.

[0006] In some embodiments, the tapping determination condition includes: within a first preset duration, the rate of change of the second kinematic parameter over time exceeds a first preset threshold and falls back below a second preset threshold, wherein the second preset threshold is a negative value.

[0007] In some embodiments, generating a corresponding control command in response to the second kinematic parameter satisfying the knocking determination condition includes: generating a corresponding control command based on the count value of the second kinematic parameter satisfying the knocking determination condition within a second preset time period, wherein different count values ​​result in different control commands.

[0008] In some embodiments, generating a corresponding control command based on the count value of the second kinematic parameter satisfying the knocking determination condition within a second preset time period includes: in response to the second kinematic parameter satisfying the knocking determination condition, controlling the detection module to stop working within a third preset time period, or not responding to the second kinematic parameter acquired by the detection module.

[0009] In some embodiments, the second preset duration is 400-600ms, and the third preset duration is 200-400ms.

[0010] In some embodiments, after controlling the detection module to operate at a second detection frequency to obtain the second kinematic parameters of the wearable device in response to the first kinematic parameter satisfying a preset wake-up condition, the detection method further includes: controlling the detection module to operate at a first detection frequency in response to the detection module operating at the second detection frequency for a duration reaching a fourth preset duration.

[0011] In some embodiments, the first detection frequency is between 200-350Hz, and the second detection frequency is greater than or equal to 400Hz.

[0012] In some embodiments, the detection module is an acceleration sensor, and the first kinematic parameter and the second kinematic parameter are the acceleration values ​​detected by the acceleration sensor or parameters calculated based on the acceleration values.

[0013] This application provides a wearable device, including a processor and a memory, wherein the memory stores a computer program, and the processor executes the computer program to implement any of the detection methods described above.

[0014] In related technologies, a high detection frequency is required for the detection module to more accurately detect the vibration waveform generated by the tapping action. However, prolonged high-frequency detection leads to significant power consumption. In the solution of this application, when the first kinematic parameter meets the preset wake-up condition, it means that a tapping action may occur. At this time, high-frequency detection is activated. Compared with the solution in related technologies that continuously uses high-frequency detection, this reduces power consumption, thereby enabling accurate tapping detection with lower power consumption.

[0015] Furthermore, from a temporal perspective, a single tapping action includes a pre-tapping phase and a post-tapping phase. In the solution of this application, the wake-up condition is set based on the wearable device's kinematic response to the pre-tapping phase of the single tapping action, and the tapping determination condition is set based on the wearable device's kinematic response to the post-tapping phase of the single tapping action. In other words, in the solution of this application, the wearable device can wake up high-frequency detection based on the kinematic response of a single tapping action and complete the tapping determination.

[0016] Since wake-up high-frequency detection and tap judgment can be completed based on the kinematic response of a single tap, when a user performs a "single" tap on the wearable device, the wearable device can detect the "single" tap and execute the first control command corresponding to the "single" tap. When the user performs a "double" tap on the wearable device, the wearable device can also detect the "double" tap and execute the second control command corresponding to the "double" tap. The second and first control commands can be used to perform different controls on the wearable device. In the solution of this application, different tap counts can be set to correspond to different control commands, thereby achieving more control functions through tapping actions and improving the user's interaction experience with the wearable device.

Detailed Implementation Methods

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0024] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The terms "first," "second," "third," etc., used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0026] This application provides a method for detecting tapping on a wearable device. The wearable device can be a clip-on earphone. In some embodiments, a clip-on earphone is used as an example, but this application is not limited to this. For example, the wearable device can also be other types of earphones, such as in-ear earphones, ear-hook earphones, behind-the-ear earphones, etc. The wearable device can also be smart glasses or a smartwatch, etc.

[0027] Figure 1 illustrates an embodiment of a wearable device worn on a wearer's ear (EAR). The wearable device can be an ear clip-on earphone 1. As shown in Figure 1, the earphone 1 includes a sound-emitting part 100 for insertion into the concha E12 of the wearer (user), an abutment part 300 for abutting against the back of the wearer's ear, and an ear hook 200 connecting the sound-emitting part 100 and the abutment part 300. In the wearing state, the ear hook 200 can bypass the wearer's auricle E17, the sound-emitting part 100 and the abutment part 300 form a clamping state on both sides of the user's auricle E17, and the sound-emitting part 100 is located within the concha E12.

[0028] The sound-emitting part 100 is a sound playback device used to convert electrical signals into sound signals and play them to the wearer. The abutment part 300 forms a clamping state with the sound-emitting part 100 so that the entire earphone 1 is clamped and worn on the user's ear. A detection module may be provided inside the abutment part 300 for performing tapping detection.

[0029] In some embodiments, the detection module may also be disposed within the sound-emitting part 100. This application does not impose any restrictions on this, and those skilled in the art can choose according to actual needs. In some embodiments, the abutment part 300 may contain devices such as batteries and circuit boards. Of course, the abutment part 300 may also not contain batteries, but the batteries may be installed in the sound-emitting part 100. This is within the scope easily understood by those skilled in the art and will not be elaborated here.

[0030] As shown in Figure 1, the ear hook 200 has a symmetrical surface A1 arranged along its length. Specifically, the difference between the ear hook 200 portions on both sides of the symmetrical surface A1 is minimal or identical. That is, if the ear hook 200 is regularly symmetrical, then the portions on both sides of the symmetrical surface A1 are identical; if the ear hook 200 is not strictly symmetrical, then the difference between the ear hook 200 portions on both sides of the symmetrical surface A1 should be minimal among various division methods. For example, the size of the difference can be distinguished by observing the projection of the ear hook 200 on a plane perpendicular to the symmetrical surface A1. When the ear-clip headphones are in a relatively ideal wearing state, the symmetrical surface A1 can be substantially parallel to the horizontal plane. It should be noted that the "substantially parallel" described in this application allows for an error range of ±15°. It is easy to understand that during use, the ear-clip headphones may slide under their own weight, causing the symmetrical surface A1 to deviate from the horizontal plane.

[0031] As shown in Figure 2, Figure 2 is a flowchart illustrating an embodiment of a tapping detection method for wearable devices. The detection method specifically includes:

[0032] S100: The control detection module operates at a first detection frequency to obtain the first kinematic parameters of the wearable device.

[0033] In some embodiments, the detection module can be an accelerometer sensor with a built-in spatial coordinate system including an X-axis, a Y-axis, and a Z-axis. The X-axis and Y-axis can both be substantially parallel to the plane of symmetry A1, and the Z-axis can be substantially perpendicular to the plane of symmetry A1 of the earcup headphones. It should be noted that the terms "substantially parallel" and "substantially perpendicular" described in this application allow for an error range of ±15°. The accelerometer sensor can detect the acceleration values ​​of the headphones in the X, Y, and Z axis directions.

[0034] In some embodiments, the first kinematic parameter can be a parameter calculated based on the acceleration values ​​of the headphones in the X, Y, and Z axis directions. In some embodiments, the first kinematic parameter can also be an acceleration value detected by an acceleration sensor in a certain direction, such as any one of the acceleration values ​​in the X, Y, and Z axis directions. This application does not limit this, and those skilled in the art can choose according to actual needs. In some embodiments, the first kinematic parameter can also be a parameter calculated based on any two of the acceleration values ​​of the headphones in the X, Y, and Z axis directions.

[0035] The first detection frequency is relatively low. That is, the acquisition frequency of the first kinematic parameter is relatively low. In some embodiments, the first detection frequency may be between 200-350Hz, for example, the first detection frequency may be 200Hz, 240Hz, 280Hz, 320Hz, or 350Hz.

[0036] S200: In response to the first kinematic parameter satisfying the preset wake-up condition, the control detection module operates at a second detection frequency to obtain the second kinematic parameter of the wearable device. The second detection frequency is greater than the first detection frequency. The second kinematic parameter and the first kinematic parameter are parameters of the same type. The wake-up condition is set according to the wearable device's initial kinematic response to a single tapping action.

[0037] The second detection frequency is greater than the first detection frequency, and the second detection frequency is relatively high, meaning that the acquisition frequency of the second kinematic parameter is relatively high. In some embodiments, the second detection frequency may be greater than or equal to 400Hz, for example, the second detection frequency may be 400Hz, 440Hz, 480Hz, 500Hz, or 550Hz.

[0038] From the machine's perspective based on wearable devices, when the first kinematic parameter meets the preset wake-up condition, it means that a tapping action may occur. At this time, the control detection module works at the second detection frequency, that is, wake-up high-frequency detection, which can more accurately detect the vibration waveform generated by the tapping action, and is conducive to improving the accuracy of tapping detection.

[0039] In the scheme of this application, the second kinematic parameter and the first kinematic parameter are parameters of the same type. The only difference between the two is the acquisition frequency. The first kinematic parameter is acquired at the first detection frequency, and the second kinematic parameter is acquired at the second detection frequency. Therefore, the first kinematic parameter and the second kinematic parameter can be collectively referred to as the kinematic parameters of the wearable device.

[0040] In some embodiments, the second kinematic parameter and the first kinematic parameter can be obtained based on the same acceleration value using the same calculation method. In some embodiments, the second kinematic parameter and the first kinematic parameter can also be acceleration values ​​of the same type. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0041] The vibration caused by a single tapping action typically lasts for a period of time, as shown in Figure 3. Figure 3(a) illustrates the change of kinematic parameters of the wearable device over time during a single tapping action. From a temporal perspective, a single tapping action consists of a pre-tapping phase and a post-tapping phase. The wake-up condition is set based on the wearable device's kinematic response to the pre-tapping phase of the single tapping action.

[0042] In some embodiments, the wake-up condition may include: the rate of change of a first kinematic parameter over time reaching a first preset threshold, wherein the first preset threshold is a positive value. The specific value of the first preset threshold is not limited in this application, and those skilled in the art can select it according to actual needs. Waking up the high-frequency detection when the first kinematic parameter gradually increases over time and the rate of change reaches the first preset threshold helps reduce the possibility of false wake-up of the high-frequency detection.

[0043] Please refer to Figure 3. Figures 3(a) and (b) are schematic diagrams showing the changes in the kinematic parameters of the wearable device over time. As shown in Figure 3(a), at time t1, the rate of change of the first kinematic parameter Slope over time reaches the first preset threshold K1, satisfying the wake-up condition, and at this time, high-frequency detection is activated. As shown in Figure 3(b), at time t2, the rate of change of the first kinematic parameter Slope over time reaches the first preset threshold K1, satisfying the wake-up condition, and at this time, high-frequency detection is activated.

[0044] S300: In response to the second kinematic parameter satisfying the preset knocking judgment condition, a corresponding control command is generated, wherein the knocking judgment condition is set according to the wearable device's kinematic response to the latter part of a single knocking action.

[0045] From the machine's perspective of the wearable device, when the second kinematic parameter meets the preset knocking judgment condition, it means that a knocking action has been detected. At this time, a corresponding control command is generated to control the wearable device accordingly.

[0046] In some embodiments, the knocking determination condition includes: within a first preset duration, the rate of change of the second kinematic parameter over time exceeds a first preset threshold and then falls back below a second preset threshold, wherein the second preset threshold is a negative value. In some embodiments, the first preset duration may be between 30-100 ms, for example, the first preset duration may be 30 ms, 50 ms, 70 ms, 90 ms, or 100 ms. The specific value of the second preset threshold is not limited in this application, and those skilled in the art can select it according to actual needs. Responding to the second kinematic parameter first gradually increasing with time within the first preset duration, and the rate of change exceeding the first preset threshold, and then gradually decreasing with time, and the rate of change being less than the second preset threshold, a knocking action is determined to have been detected. This helps to avoid false detection of knocking actions and improves the accuracy of knocking detection.

[0047] Please refer to Figure 3. As shown in Figure 3(a), within the first preset duration T1, the rate of change of the second kinematic parameter Slope exceeds the first preset threshold K1 and falls back below the second preset threshold K2, satisfying the knocking judgment condition, meaning that a knocking action was detected. As shown in Figure 3(b), within the first preset duration T1, the rate of change of the second kinematic parameter Slope exceeds the first preset threshold K1, but does not fall back below the second preset threshold K2, not satisfying the knocking judgment condition, meaning that no knocking action was detected.

[0048] In related technologies, a high detection frequency is required for the detection module to more accurately detect the vibration waveform generated by the tapping action. However, prolonged high-frequency detection leads to significant power consumption. In the solution of this application, when the first kinematic parameter meets the preset wake-up condition, it means that a tapping action may occur. At this time, high-frequency detection is activated. Compared with the solution in related technologies that continuously uses high-frequency detection, this reduces power consumption, thereby enabling accurate tapping detection with lower power consumption.

[0049] Furthermore, from a temporal perspective, a single tapping action includes a pre-tapping phase and a post-tapping phase. In the solution of this application, the wake-up condition is set based on the wearable device's kinematic response to the pre-tapping phase of the single tapping action, and the tapping determination condition is set based on the wearable device's kinematic response to the post-tapping phase of the single tapping action. In other words, in the solution of this application, the wearable device can wake up high-frequency detection based on the kinematic response of a single tapping action and complete the tapping determination.

[0050] Since wake-up high-frequency detection and tap judgment can be completed based on the kinematic response of a single tap, when a user performs a "single" tap on the wearable device, the wearable device can detect the "single" tap and execute the first control command corresponding to the "single" tap. When the user performs a "double" tap on the wearable device, the wearable device can also detect the "double" tap and execute the second control command corresponding to the "double" tap. The second and first control commands can be used to perform different controls on the wearable device. In the solution of this application, different tap counts can be set to correspond to different control commands, thereby achieving more control functions through tapping actions and improving the user's interaction experience with the wearable device.

[0051] It should be noted that, in the description of this application, "single tap" means that the user performs only a single tap within the second preset duration; "double tap" means that the user performs two consecutive taps within the second preset duration. In some embodiments, the second preset duration is between 400-600ms, for example, the second preset duration can be 400ms, 450ms, 500ms, 550ms, or 600ms.

[0052] Therefore, in some embodiments, generating a corresponding control command in response to the second kinematic parameter satisfying the knocking determination condition includes: generating a corresponding control command based on the count value of the second kinematic parameter satisfying the knocking determination condition within a second preset time period, wherein different count values ​​result in different control commands.

[0053] For example, a wearable device can be equipped with a register to store a count value indicating that a second kinematic parameter meets a tapping condition within a second preset time period. The count value in the register can be preset to 0. When the second kinematic parameter meets the tapping condition, the count value in the register is incremented by 1, and timing begins. Subsequently, in response to the second kinematic parameter meeting the tapping condition, the count value in the register is incremented by 1 until the second preset time period is reached. After the second preset time period is reached, a corresponding control command can be generated based on the count value in the register, and the count value in the register can be reset to 0.

[0054] After the timer reaches the second preset duration, if the count value in the register is 1, a first control instruction corresponding to "single click" can be generated; if the count value in the register is 2, a second control instruction corresponding to "double click" can be generated. The second control instruction and the first control instruction are used to perform different controls on the wearable device.

[0055] After each tapping action, the resulting vibration may lead to false detections of the tap. For example, if a user applies significant force during a single tapping action, the vibration from that single tap may be falsely detected as a second tapping action. To avoid this, a quiet time window can be set after a tapping action is detected. During this quiet time window, the second kinematic parameter is not acquired, or the rate of change of the second kinematic parameter is not detected.

[0056] Therefore, in some embodiments, generating a corresponding control command based on the count value of the second kinematic parameter satisfying the knocking determination condition within a second preset time period includes: in response to the second kinematic parameter satisfying the knocking determination condition, controlling the detection module to stop working within a third preset time period, or not responding to the second kinematic parameter obtained by the detection module.

[0057] The third preset duration corresponds to the quiet time window. In some embodiments, the third preset duration can be between 200-400ms. For example, the third preset duration can be 200ms, 250ms, 300ms, 350ms, or 400ms. The third preset duration is less than the fourth preset duration.

[0058] For example, the detection module can be stopped from working, thereby ceasing to acquire the second kinematic parameters to avoid false detections caused by vibrations generated by the striking action. Alternatively, the second kinematic parameters acquired by the detection module can be ignored, for example, by ceasing to detect the rate of change of the second kinematic parameters, to avoid false detections caused by vibrations generated by the striking action. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0059] As shown in Figure 4, which is a flowchart of another embodiment of the tapping detection method for wearable devices, after step S200, the detection method may further include:

[0060] S400: In response to the detection module operating at the second detection frequency for a duration of a fourth preset duration, the detection module is controlled to operate at the first detection frequency.

[0061] The fourth preset duration can be between 3 and 7 seconds. For example, the fourth preset duration can be 3 seconds, 4 seconds, 5 seconds, 6 seconds, or 7 seconds. After the high-frequency detection continues for the fourth preset duration, the operating frequency of the detection module can be reduced from the second detection frequency to the first detection frequency to further reduce the power consumption of the wearable device.

[0062] In addition, this application also provides a wearable device 500. Please refer to FIG5, which is a schematic diagram of the structure of an embodiment of the wearable device. The wearable device 500 includes a memory 510, a processor 520, and a computer program stored in the memory 510 and executable on the processor 520. When the processor 520 executes the computer program, it implements the steps of any of the tapping detection methods described above.

A general-purpose processor can be a microprocessor, or the processor 520 can be any conventional processor.

[0064] The memory 510 may include random access memory (RAM), read-only memory (ROM), flash memory, erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), registers, hard disk, removable disk, CD-ROM, etc. The memory 510 may store program data, which may include, for example, a single instruction or many instructions, and may be distributed across several different code segments, distributed among different programs, and distributed across multiple memories. The memory 510 may be coupled to the processor 520 so that the processor 520 can read and write information to / from the memory 510. Of course, the memory 510 may be integrated into the processor 520; this application does not limit this, and those skilled in the art can choose according to actual needs.
