[0032] This disclosure can be applied to wearable devices (e.g., head-mounted displays, watches, wristbands, bracelets, etc.), terminal devices, servers, and other electronic devices, which can operate in conjunction with numerous other general-purpose or special-purpose computing system environments or configurations. Wearable devices, terminal devices, servers, and other electronic devices can be described in the general context of computer system executable instructions (such as program modules) executed by a computer system. Typically, program modules can include routines, programs, object programs, components, logic, data structures, etc., which perform specific tasks or implement specific abstract data types. The computer system / server can be implemented in a distributed cloud computing environment, where tasks are performed by remote processing devices linked via a communication network. In a distributed cloud computing environment, program modules can reside on local or remote computing system storage media, including storage devices.

[0033] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0034] Figure 1 is an exemplary system architecture applicable to embodiments of the method or apparatus for controlling wearable devices disclosed herein. This system architecture may include a display screen 1, a connection portion 2, a controller 3, and a sensor 4. The connection portion 2 can provide a medium for a communication link between the display screen 1, the controller 3, and the sensor 4. The connection portion 2 may include various connection types, such as wired or wireless communication links, or fiber optic cables, etc.

[0035] The aforementioned display screen 1 can be the display screen of a wearable device, and the controller 3 can be an MCU (Microcontroller Unit) or other component with corresponding control functions on the wearable device. Alternatively, the controller 3 can be a component in an external device connected to the wearable device. External devices can include adapters, mobile phones, tablets, computers, servers, etc. The sensor 4 can include at least one of the following: capacitive sensor, Hall sensor, pressure sensor, IMU, magnetometer, accelerometer, angular velocity sensor, speed sensor, image sensor, etc.

[0036] Wearable devices can be devices with only image display capabilities, allowing users to view flat or three-dimensional images or videos. Wearable devices can also be electronic devices that combine image display and audio playback capabilities. Wearable devices include head-mounted displays, which include, but are not limited to, augmented reality (AR) devices, virtual reality (VR) devices, and mixed reality (MR) devices.

[0037] Controller 3 can perform various controls on the wearable device. For example, when the wearable device is powered on, controller 3 controls the display screen of the wearable device to turn on; when sensor 4 detects that the wearable device meets the pre-configured screen-off conditions, controller 3 controls the display screen of the wearable device to turn off.

[0038] Exemplary methods

[0039] Figure 2 is a flowchart illustrating a method for controlling a wearable device according to an exemplary embodiment of this disclosure. Embodiments of this disclosure can be applied to electronic devices. As shown in Figure 2, the method includes the following steps:

[0040] Step 210: When the wearable device is powered on, control the display screen of the wearable device to turn on.

[0041] In some alternative embodiments of this disclosure, the wearable device may be a device that includes a power source.

[0042] In some alternative embodiments of this disclosure, the wearable device may be a device that does not contain a power source.

[0043] In some optional embodiments of this disclosure, when the wearable device includes a power source, it can be powered on by its own power supply. For example, a power switch can be provided on the wearable device, and powering on the wearable device is achieved by turning on the power switch. When the wearable device does not include a power source, it can be powered on by an external device. For example, the wearable device can be connected to an adapter, mobile phone, host, or other external device, which then powers the wearable device. For example, Figure 3 is a schematic diagram of the connection between a wearable device and an external device provided in an exemplary embodiment of this disclosure. As shown in Figure 3, the wearable device is a head-mounted display device, and the external device is an adapter. The head-mounted display device is connected to the adapter, which includes a power source, or the adapter can be connected to a power source. After the head-mounted display device is connected to the adapter, the adapter powers the head-mounted display device. In practical applications, the wearable device is not limited to a head-mounted display device, and the external device is not limited to an adapter.

[0044] In some alternative embodiments of this disclosure, the wearable device may include at least one display screen. For example, taking a head-mounted display device as an example, the head-mounted display device may include two displays: a first screen and a second screen.

[0045] In some optional embodiments of this disclosure, the wearable device's display screen can be controlled to light up once it is powered on.

[0046] In some optional embodiments of this disclosure, the display screen of the wearable device can be turned on to display preset content (or preset screen, initial display content).

[0047] Step 230: When the wearable device is detected to meet the pre-configured screen-off conditions, control the display of the wearable device to turn off.

[0048] In some optional embodiments of this disclosure, the pre-configured screen-off conditions may include conditions corresponding to a preset detection method. The preset detection method may include at least one detection method. For example, the preset detection method may include a method for detecting the wearing state of the wearable device, a method for detecting the movement state of the wearable device, and a method for detecting the displayed content of the wearable device. The wearing state may include an approach state, a distance state, etc. For example, when the wearable device is in a distance state, it indicates that the user wants to remove the wearable device, and the wearable device meets the screen-off conditions, so the display screen of the wearable device can be controlled to turn off. The movement state may include a stationary state and a non-stationary state. Normally, when a user wears a wearable device, it is difficult for the wearable device to remain stationary. When the wearable device is in a stationary state, it can be assumed that the user is not wearing the wearable device, and the display screen of the wearable device can be controlled to turn off. The displayed content may include a changing state and a non-changing state. Normally, when a user uses a wearable device, the displayed content of the wearable device does not remain the same. When the displayed content is in a non-changing state, it can be assumed that the user is not using the wearable device, and the display screen of the wearable device can be controlled to turn off.

[0049] In some optional embodiments of this disclosure, the preset detection method may include detection using a capacitive sensor on the wearable device, detection using an inertial measurement unit (IMU) on the wearable device, and so on. The detection value of the capacitive sensor can characterize the user's wearing status of the wearable device. Based on the detection value of the capacitive sensor, the display screen of the wearable device can be turned off in a timely manner when the user removes the wearable device or is not wearing it, to avoid power consumption or screen burn-in. IMU data on the wearable device can characterize the movement of the wearable device. If the wearable device is stationary, it can be inferred that the wearable device is not being worn by the user. Based on IMU detection, the display screen of the wearable device can be turned off in a timely manner when the wearable device is stationary, to avoid power consumption or screen burn-in. In practical applications, the detection methods are not limited to those described above.

[0050] The method for controlling wearable devices provided in this disclosure can control the display screen to turn on in response to the wearable device being powered on. After the screen turns on, it detects whether the wearable device meets the pre-configured screen-off conditions. If the wearable device meets the pre-configured screen-off conditions, it controls the display screen to turn off in a timely manner, which can avoid power consumption or screen burn-in.

[0051] Figure 4 is a flowchart illustrating a method for controlling a wearable device provided in another exemplary embodiment of this disclosure.

[0052] In some optional embodiments of this disclosure, based on the embodiment shown in FIG2, as shown in FIG4, after controlling the display screen of the wearable device to turn on, the method of the embodiments of this disclosure may further include:

[0053] Step 220: Detect whether the wearable device meets the screen-off conditions.

[0054] In some optional embodiments of this disclosure, it is possible to detect in real time whether the wearable device meets the screen-off conditions.

[0055] In some optional embodiments of this disclosure, the wearable device may be periodically checked to determine whether the screen-off condition is met.

[0056] In some optional embodiments of this disclosure, whether a wearable device meets the screen-off condition can be detected by at least one of the following methods: determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device; determining whether the wearable device meets the screen-off condition based on the motion data of the wearable device; or determining whether the wearable device meets the screen-off condition based on the display content change information of the display screen of the wearable device.

[0057] In some optional embodiments of this disclosure, it may be possible to determine whether a wearable device meets the screen-off condition based solely on the detection values ​​of the capacitive sensors on the wearable device.

[0058] In some optional embodiments of this disclosure, it may be possible to determine whether a wearable device meets the screen-off condition based solely on the motion data of the wearable device.

[0059] In some optional embodiments of this disclosure, it may be possible to determine whether a wearable device meets the screen-off condition based solely on information about changes in the content displayed on the device's screen.

[0060] In some optional embodiments of this disclosure, the wearable device's screen-off condition can be detected based on two of the three methods described above. For example, the screen-off condition can be determined based on the detection value of the capacitive sensor on the wearable device and the device's motion data. In some optional embodiments of this disclosure, all three methods can be used together to detect whether the wearable device meets the screen-off condition.

[0061] In some optional embodiments of this disclosure, when the wearable device is a head-mounted display device, the electrode plate of the capacitive sensor can be positioned on the wearable device at the location where it contacts the user's ear. When the head-mounted display device has temples, a headband, or other securing components (components for securing the head-mounted display device to the user's head), for example, the electrode plate can be positioned at the location where the securing component contacts the ear. The electrode plate of the capacitive sensor can be a flexible electrode plate. For example, if the securing component is a temple, the temple can be a flexible temple. During the wearing of the head-mounted display device, the electrode plate of the capacitive sensor can contact the skin above the user's ear, thereby allowing the detection value of the capacitive sensor to characterize the user's wearing status of the head-mounted display device.

[0062] In some optional embodiments of this disclosure, the detection value of the capacitive sensor can be the result of processing the data collected by the capacitive sensor. For example, the read capacitance value can be processed according to a pre-configured algorithm logic to obtain a detection value that can characterize the wearing state of the wearable device.

[0063] In some optional embodiments of this disclosure, the capacitance sensor may include a control component (or control circuit) and electrode plates. The control component can acquire the capacitance signal of the electrode plates and process the capacitance signal to obtain a detection value. The electrode plates have two sides; the two electrode plates on the signal side can be used to detect capacitance changes, and the electrode plate on the shielding side can be used to eliminate signal interference. Optionally, the control component may be a control chip, set at a preset position on the wearable device, to acquire the capacitance signal of the electrode plates and process the capacitance signal.

[0064] In some optional embodiments of this disclosure, the wearable device may be determined to meet the screen-off condition based on the relationship between the detection value of the capacitive sensor and a pre-configured threshold.

[0065] In some optional embodiments of this disclosure, motion data from the wearable device can be acquired using sensors on the wearable device. These sensors may include, for example, at least one of an IMU, an accelerometer, an angular velocity sensor, a velocity sensor, a magnetometer, etc.

[0066] In some optional embodiments of this disclosure, corresponding screen-off conditions can be set according to the correlation between motion data and the wearing status of the wearable device, and then the wearable device can be judged based on the motion data to determine whether the screen-off conditions are met.

[0067] In some optional embodiments of this disclosure, the screen-off condition can be preset based on the correlation between the wearable device's motion state and its wearing state. The motion state of the wearable device can then be further determined based on motion data, and subsequently, it can be determined whether the wearable device meets the screen-off condition. For example, if the wearable device is stationary, it indicates that the wearable device is not being worn by the user, and the wearable device is determined to meet the screen-off condition.

[0068] In some optional embodiments of this disclosure, whether the content displayed on the display screen of the wearable device changes can indicate whether the wearable device is being worn or the motion state of the wearable device.

[0069] In some optional embodiments of this disclosure, the motion state can include an absolute motion state and a relative motion state. An absolute motion state can include the motion state of the wearable device relative to a fixed position (e.g., a specified position in a world coordinate system). For example, the wearable device may be moving or stationary relative to the world coordinate system. A relative motion state can include the motion state of the wearable device relative to a mobile platform. The mobile platform may include, for example, a car, a train, an airplane, etc.

[0070] In some optional embodiments of this disclosure, the change information of the display content of the wearable device can be determined based on the similarity between the display content at the current moment and the display content at historical moments. For example, if the display content of the wearable device remains unchanged for a long time, it indicates that the wearable device is not being worn, and it is determined that the wearable device meets the screen-off condition.

[0071] In this embodiment, data such as the detection value of the capacitive sensor, the motion data of the wearable device, and the display content change information of the wearable device's display screen can effectively characterize the wearing status of the wearable device, effectively determine whether the wearable device meets the screen-off conditions, and can control the display screen of the wearable device to turn off in a timely manner to avoid power consumption or screen burn-in.

[0072] In some optional embodiments of this disclosure, determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device may include: determining the user's wearing status of the wearable device based on the detection value of the capacitive sensor; and determining whether the wearable device meets the screen-off condition based on the wearing status.

[0073] In some optional embodiments of this disclosure, the user's wearing state of the wearable device may include an approach state, a distance state, or a removed state. When the configuration state is either a distance state or a removed state, it is determined that the wearable device meets the screen-off condition. The user's wearing state of the wearable device can be determined based on the correlation between the detection value of the capacitive sensor and the wearing state.

[0074] In some optional embodiments of this disclosure, when the wearable device is powered on before the user puts it on, the detection value of the capacitive sensor continuously increases from its initial value. If the detection value increases to a value greater than a specified threshold (referred to as the first threshold), it is determined that the wearable device is in an approach state, i.e., the user is putting on the wearable device, and thus it is determined that the wearable device does not meet the screen-off condition. In this case, the detection value of the capacitive sensor can continue to be monitored to continuously determine whether the detection value decreases. If the detection value decreases to a value less than a second threshold, it can be determined that the wearable device is in a distance state, and thus it can be determined that the wearable device meets the screen-off condition, and the display screen is controlled to turn off. The second threshold is less than the first threshold. Setting the second threshold to be less than the first threshold can prevent the display screen from being mistakenly turned off when the user is wearing the wearable device, but slight movement of the wearable device causes a small fluctuation in the detection value of the capacitive sensor.

[0075] In some optional embodiments of this disclosure, after the wearable device is powered on, if the detection value of the capacitive sensor remains at the initial value or is less than the second threshold for a long time, it can be determined that the wearable device has not been worn for a long time and that the wearable device meets the screen-off condition.

[0076] In some optional embodiments of this disclosure, when the user puts on the wearable device before powering it on, the capacitance sensor's power-on initialization calibration will subtract the capacitance generated by wearing the device as an excess, making the initial value of the capacitance sensor relatively smaller than the initial value when it is not worn. After the user removes the wearable device, the detection value of the capacitance sensor will become very small. In this case, a third threshold can be predefined. After the wearable device is powered on, the detection value of the capacitance sensor is continuously monitored. If the detection value decreases to less than the third threshold, it can be determined that the user's wearing state of the wearable device is the removed state, and thus the wearable device meets the screen-off condition.

[0077] In this embodiment, the wear status of the wearable device can be effectively determined by the detection value of the capacitive sensor on the wearable device. Based on this, the display screen can be turned off in a timely manner when the user removes the wearable device or when it has not been worn for a long time, effectively avoiding power consumption or screen burn-in.

[0078] In some optional embodiments of this disclosure, determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device may include:

[0079] If the detection value of the capacitive sensor is greater than the first threshold, the wearable device is determined not to meet the screen-off condition. If the detection value of the capacitive sensor is less than the second threshold, the wearable device is determined to meet the screen-off condition; the second threshold is less than the first threshold.

[0080] In some optional embodiments of this disclosure, the first threshold and the second threshold can be set based on empirical values ​​under different wearing states of the wearable device. For example, the first threshold and the second threshold can be determined through experimentation.

[0081] In some optional embodiments of this disclosure, the determination of whether a wearable device meets the screen-off condition is not limited to the detection value of the capacitive sensor; the motion state of the wearable device can also be considered. For example, the screen-off condition can be determined when the detection value of the capacitive sensor is less than a second threshold and the head-mounted display is stationary. This is to avoid misjudging that the user has removed the wearable device due to the detection value of the capacitive sensor in special scenarios. Special scenarios may include situations where, after the user wears the wearable device, due to the user's body characteristics (e.g., hair, clothing), there is a certain distance between the wearable device and the user's skin. When the user presses the wearable device towards their body after wearing it, the detection value of the capacitive sensor may misjudge that the user has removed the wearable device.

[0082] In some optional embodiments of this disclosure, the capacitive sensor may be provided with an enable terminal. After the wearable device is powered on, an enable signal can be provided to the enable terminal of the capacitive sensor, causing the capacitive sensor to enter an enabled state. The capacitive sensor is initialized in the enabled state, and the detection value of the initialized capacitive sensor is the initial value.

[0083] In some optional embodiments of this disclosure, if the detection value of the capacitive sensor increases to a value greater than a first threshold, it is determined that the wearable device does not meet the screen-off condition. During the process from when the wearable device approaches the user until the user puts on the wearable device, the detection value of the capacitive sensor increases from its initial value to a value greater than the first threshold (which may be referred to as the proximity threshold). That is, a detection value greater than the first threshold indicates that the wearable device is in a state of approaching the user (referred to as the proximity state). Therefore, based on the detection value being greater than the first threshold, it can be determined that the wearable device does not meet the screen-off condition, and the display screen remains on.

[0084] In some optional embodiments of this disclosure, the case where the detection value of the capacitive sensor is less than the second threshold may include, after the wearable device is powered on, the user wears the wearable device, causing the detection value of the capacitive sensor to increase to greater than the first threshold. The user then removes the wearable device, causing the detection value of the capacitive sensor to decrease from greater than the first threshold to less than the second threshold (which may be referred to as the distance threshold). In this case, it is determined that the wearable device meets the screen-off condition.

[0085] In some optional embodiments of this disclosure, if the detection value of the capacitive sensor remains at or near the first initial value for a prolonged period after the wearable device is powered on, the screen-off condition can be determined to be met. The first initial value is the initial value at which the capacitive sensor is initialized when the wearable device is not worn. For example, the change in the detection value within a preset time period can be determined. If the detection value remains at the first initial value within the preset time period, or the difference between the detection value and the first initial value is within a preset error range, the screen-off condition is determined to be met.

[0086] This embodiment of the invention sets proximity thresholds and distance thresholds, which can accurately determine whether a wearable device meets the screen-off conditions based on the relationship between the detection value of the capacitive sensor and the proximity thresholds and the distance thresholds, so as to control the display screen to turn off in a timely manner when the screen-off conditions are met.

[0087] In some optional embodiments of this disclosure, determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device includes: determining that the wearable device meets the screen-off condition when the detection value of the capacitive sensor is less than a third threshold.

[0088] In some optional embodiments of this disclosure, the third threshold can be set based on the scenario where the user puts on the wearable device before powering it on (hereinafter referred to as "wearing before powering on"). This is because, when the user puts on the device before powering it on, the initial calibration of the capacitive sensor will subtract the capacitance value generated by wearing the device along with the environmental capacitance, making the initial value of the capacitive sensor relatively smaller than the initial value when the device is not worn. After the user removes the wearable device, the detection value of the capacitive sensor will decrease to less than the third threshold. In other words, if the detection value of the capacitive sensor is less than the third threshold after the wearable device is powered on, it indicates that the current scenario is "wearing before powering on," and the user has removed the wearable device, thus determining that the wearable device meets the screen-off condition.

[0089] In this embodiment of the disclosure, for the case where the user wears the device before powering it on, the detection value of the capacitive sensor can accurately indicate whether the user has removed the wearable device by checking if it is less than a third threshold. If the detection value is less than the third threshold, it can be accurately determined that the wearable device meets the screen-off condition, thereby enabling timely control of the display screen to turn off.

[0090] In some optional embodiments of this disclosure, the third threshold is less than the initial value of the capacitive sensor, which is less than the second threshold.

[0091] In some optional embodiments of this disclosure, the initial value of the capacitive sensor is the initial value used to initialize the capacitive sensor when the wearable device is not worn.

[0092] In some optional embodiments of this disclosure, if the user wears the device before powering on, and the detection value of the capacitive sensor is greater than a third threshold, the display screen needs to remain on. The display screen is only turned off when the detection value decreases to below the third threshold, confirming that the screen-off condition is met.

[0093] In this embodiment, the third threshold is understood to be less than the initial value of the capacitive sensor, the initial value of the capacitive sensor is less than the second threshold, and the second threshold is less than the first threshold. By setting the third threshold to be less than the initial value of the capacitive sensor, when the user wears the device before powering it on, the comparison between the third threshold and the detection value of the capacitive sensor can accurately detect when the user removes the wearable device. When the user powers on the device before wearing it, the comparison between the first threshold and the detection value of the capacitive sensor can accurately determine when the user is wearing the wearable device, thus keeping the display screen on. Furthermore, based on the comparison between the second threshold and the detection value of the capacitive sensor, the comparison can accurately determine when the user removes the wearable device after wearing it, triggering the display screen to turn off in a timely manner. This achieves display screen on / off control under different user operations.

[0094] In some optional embodiments of this disclosure, when it is determined that the wearable device meets the screen-off condition, the method of this disclosure may further include: initializing the capacitive sensor to an initial value, wherein the initial value is greater than a third threshold and less than a second threshold.

[0095] In some optional embodiments of this disclosure, for cases where the user wears the device before powering it on, even if the wearable device meets the screen-off condition, the initial calibration of the capacitive sensor is affected by the capacitance value generated by wearing the device. Therefore, even if the user removes the wearable device (which triggers screen-off), the detection value of the capacitive sensor differs significantly from the initial calibration value when the device is not worn. This results in subsequent detection values ​​being unusable to trigger the screen to turn on again. To address this, when the wearable device meets the screen-off condition, the initial value of the capacitive sensor needs to be initialized. Since the user has removed the wearable device at this point, the initial calibration of the capacitive sensor is not affected by the capacitance value generated by wearing the device. This allows the initialized detection value of the capacitive sensor to continue comparing with the first threshold and the second threshold to determine whether the screen should be turned on or off.

[0096] In this embodiment of the disclosure, when the wearable device meets the screen-off condition, the initial value of the capacitive sensor is initialized, so that the detection value of the capacitive sensor returns to normal, eliminating the influence of the capacitance value generated by wearing on the detection value, and so that the detection value of the capacitive sensor can continue to be used for subsequent screen-on and screen-off control.

[0097] Figure 5 is a schematic flowchart of an exemplary embodiment of the present disclosure for detecting whether the screen-off condition is met.

[0098] In some optional embodiments of this disclosure, as shown in FIG5, determining whether the wearable device meets the screen-off condition based on the motion data of the wearable device may include:

[0099] Step 2210: Obtain motion data from the wearable device.

[0100] In some optional embodiments of this disclosure, motion data may include motion-related data such as posture information, angular velocity information, and acceleration information of the wearable device.

[0101] Step 2220: Determine the motion state of the wearable device based on motion data.

[0102] In some optional embodiments of this disclosure, the motion state of the wearable device can include both stationary and moving states. For example, data collected by sensors such as an inertial measurement unit can determine the position change information and angle change information of the wearable device. The motion state of the wearable device can then be determined based on the position change information and angle change information. For instance, if the wearable device satisfies at least one of the following conditions: the position change information is greater than a position threshold, or the angle change information is greater than an angle threshold, the motion state of the wearable device can be determined to be moving; otherwise, the motion state of the wearable device can be determined to be stationary.

[0103] In some optional embodiments of this disclosure, the motion state of the wearable device can be comprehensively determined by combining motion data over a certain period of time to ensure the accuracy of the motion state. For example, at the current moment, the motion state of the wearable device can be determined by combining the motion data at the current moment with motion data from at least one historical moment.

[0104] Step 2230: When the motion state is stationary, determine that the wearable device meets the screen-off condition.

[0105] In some optional embodiments of this disclosure, if the motion state of the wearable device is determined to be stationary, it can be indicated that the wearable device is not being worn by the user. Therefore, it can be determined that the wearable device meets the screen-off condition.

[0106] In this embodiment of the disclosure, the motion state of the wearable device is determined by motion data. The motion state can effectively determine whether the wearable device meets the screen-off conditions, so that the display screen can be turned off in a timely manner when the screen-off conditions are met.

[0107] In some optional embodiments of this disclosure, as shown in FIG5, the method of the embodiments of this disclosure may further include:

[0108] Step 2240: When the wearable device is in motion, if it is on a mobile platform, acquire the motion data of the mobile platform.

[0109] In some optional embodiments of this disclosure, the mobile platform may include equipment such as automobiles, high-speed trains, and aircraft. Motion data of the mobile platform can be obtained from sensors on the mobile platform or from other electronic devices that can characterize the motion of the mobile platform. The motion data of the mobile platform can be used to determine the pose, velocity, angular velocity, etc., of the mobile platform.

[0110] Step 2250: Based on the motion data of the mobile platform and the motion data of the wearable device, determine the relative motion state of the wearable device relative to the mobile platform.

[0111] In some optional embodiments of this disclosure, the pose change information of the mobile platform can be determined based on the motion data of the mobile platform. The pose change information of the wearable device can be determined based on the motion data of the wearable device. Based on the pose change information of the wearable device and the pose change information of the mobile platform, the relative motion state of the wearable device relative to the mobile platform can be determined. For example, if the pose change information of the wearable device is consistent with the pose change information of the mobile platform, the relative motion state of the wearable device relative to the mobile platform can be determined to be relatively stationary. Conversely, if they are inconsistent, the relative motion state of the wearable device relative to the mobile platform can be determined to be relative motion. Whether the pose change information of the wearable device is consistent with the pose change information of the mobile platform can be determined by whether the difference between the pose change information of the wearable device and the pose change information of the mobile platform is less than a threshold. If the difference between the pose change information of the wearable device and the pose change information of the mobile platform is less than the threshold, it indicates that the position and angle changes of the wearable device are very similar to those of the mobile platform, therefore, the wearable device is determined to be stationary relative to the mobile platform.

[0112] In some optional embodiments of this disclosure, the pose information of the wearable device relative to the world coordinate system can be determined based on the motion data of the wearable device. The pose information of the mobile platform relative to the world coordinate system can be determined based on the motion data of the mobile platform. The pose information of the wearable device relative to the mobile platform can be determined based on the pose information of the wearable device and the pose information of the mobile platform. By combining the pose information of the wearable device relative to the mobile platform at different times, the relative motion state of the wearable device relative to the mobile platform can be determined.

[0113] Step 2260: When the relative motion state is relatively stationary, determine that the wearable device meets the screen-off condition.

[0114] In some optional embodiments of this disclosure, if the wearable device is relatively stationary relative to the mobile platform, it indicates that the wearable device is placed on the mobile platform and is not being worn by the user. Therefore, it can be determined that the wearable device meets the screen-off condition.

[0115] In this embodiment, when the wearable device is on a mobile platform, if the wearable device is in motion, the relative motion state between the wearable device and the mobile platform can be further determined by combining the motion data of the mobile platform. If the wearable device is stationary relative to the mobile platform, it indicates that the wearable device is not being worn, meeting the screen-off condition, and the screen can be triggered in a timely manner, improving the accuracy and timeliness of triggering the screen-off. This avoids situations where the wearable device is placed on the mobile platform for a long time without being worn, while the display screen remains on.

[0116] In some optional embodiments of this disclosure, as shown in FIG5, the method of the embodiments of this disclosure may further include:

[0117] Step 2270: In the absence of motion data from the mobile platform, determine whether the wearable device meets the screen-off condition based on the changes in the display content of the wearable device's screen.

[0118] In some optional embodiments of this disclosure, the display content change information can characterize whether the wearable device is being worn, because the display content usually changes when the user is wearing the wearable device. Therefore, when determining the wearable device's movement based on its motion data, if the motion data of the mobile platform is unavailable, the display content change information of the wearable device's screen can be used to determine whether the wearable device meets the screen-off condition.

[0119] In this embodiment of the disclosure, when the motion of the wearable device is determined based on the motion data of the wearable device, it is also possible to further determine whether the wearable device meets the screen-off condition based on the display content change information of the display screen of the wearable device, so as to ensure that the wearable device can control the screen-off in a timely manner when it is on a mobile platform, and avoid the situation where the wearable device is placed on a mobile platform for a long time without being worn, while the display screen remains on.

[0120] Figure 6 is a flowchart illustrating the process of detecting whether the screen-off conditions are met, provided in another exemplary embodiment of this disclosure.

[0121] In some optional embodiments of this disclosure, determining whether the wearable device meets the screen-off condition based on the display content change information of the wearable device's display screen may include:

[0122] Step 310: Determine the relative change information of the display content at the current moment relative to the historical display content at at least one historical moment.

[0123] In some optional embodiments of this disclosure, the content displayed on the screen at the current moment can be obtained from the display controller of the wearable device. The content displayed at the current moment can be the image, pixel data, etc., currently displayed on the screen.

[0124] In some optional embodiments of this disclosure, the historical display content of at least one historical moment can be cached in real time to ensure that, as time progresses, the historical display content of at least one historical moment prior to the current moment can be obtained at the current moment. For example, if the current moment is denoted as t, the historical display content of n historical moments t-1, t-2, ..., tn can be cached using a time window. Whenever new display content is generated, the earliest display content is discarded and the new display content is stored as the historical display content of the next historical moment required by the time window.

[0125] In some optional embodiments of this disclosure, the relative change information of the displayed content at the current moment relative to the historical displayed content at a historical moment can be obtained by comparing the displayed content at the current moment with the historical displayed content at a historical moment. The comparison method includes, but is not limited to, calculating the distance (e.g., Euclidean distance) and similarity (e.g., cosine similarity) between the displayed content at the current moment and the historical displayed content, etc., and is not specifically limited.

[0126] Step 320: If the relative change information meets the pre-configured static conditions, determine that the wearable device meets the screen-off conditions.

[0127] In some optional embodiments of this disclosure, the pre-configured stillness condition can be set according to the representation of relative change information. For example, when the relative change information is the similarity between the currently displayed content and the historical displayed content, the pre-configured stillness condition can be that the similarity is greater than a similarity threshold. When the relative change information is the distance between the currently displayed content and the historical displayed content, the pre-configured stillness condition can be that the distance between the currently displayed content and the historical displayed content is less than a distance threshold. Specific stillness conditions are not limited. When the relative change information satisfies the stillness condition, it is determined that the wearable device meets the screen-off condition, and the display screen needs to be turned off to avoid power consumption or screen burn-in.

[0128] In some optional embodiments of this disclosure, the relative change information of the current display content with the historical display content at multiple historical times can be combined to comprehensively determine whether the screen-off condition is met, thereby improving the accuracy of the judgment result. For example, if the relative change information of the display content at the current time t with the information at times t-1, t-2, ..., tn all meet the pre-configured static condition, it is determined that the wearable device meets the screen-off condition.

[0129] In this embodiment of the disclosure, since the change information of the display content of the display screen can effectively characterize whether the wearable device is being worn or used, based on the change information of the display content of the wearable device's display screen, it is possible to effectively determine whether the wearable device meets the screen-off conditions, and control the screen-off in a timely manner to avoid power consumption or screen burn-in.

[0130] Figure 7 is a flowchart illustrating a method for controlling a wearable device provided in another exemplary embodiment of this disclosure.

[0131] In some optional embodiments of this disclosure, based on any of the above embodiments, as shown in FIG7, the method of the embodiments of this disclosure may further include:

[0132] Step 410: When the wearable device is powered on, control the capacitive sensor on the wearable device to enter the enabled state so that the capacitive sensor is initialized and enters the working state.

[0133] In some optional embodiments of this disclosure, the capacitive sensor can be initialized and put into operation by providing an enable signal to the capacitive sensor. The initialization principle of the capacitive sensor will not be elaborated upon.

[0134] In some optional embodiments of this disclosure, the capacitive sensor satisfies min after initialization. thr <counts<low thr <high thr Among them, min thrThis represents the third threshold mentioned above. `counts` represents the real-time detection value from the capacitive sensor. The real-time detection value after initialization is the initial value. `low` thr This represents the second threshold mentioned above (i.e., the threshold farthest from the threshold). high thr This represents the first threshold mentioned above (i.e., the proximity threshold).

[0135] In some optional embodiments of this disclosure, for wearable devices, the following four states can be defined:

[0136] Pending state: After the wearable device is powered on and the capacitive sensor is initialized, the current state is unknown and it is in a pending state. At this time, the screen is turned on by default, that is, the display of the wearable device is turned on.

[0137] Approaching state: When counts exceed high thr Afterwards, the wearable device is in a state close to the user's skin (referred to as the proximity state), as long as the counts are not less than low. thr They believe that wearable devices will always be in a near-terminal state, that is, the display screen will remain on.

[0138] Distance state: When the wearable device is in the proximity state, if counts begin to be less than low thr It assumes that the wearable device has entered a remote state and triggers the screen to turn off.

[0139] Reverse state: After the wearable device is powered on and the capacitive sensor is initialized, if counts begin to be less than min... thr The system assumes the wearable device is in a reversed state, corresponding to the user removing the wearable device, triggering a screen-off event. In this case, the third threshold min... thr It can also be called the reverse threshold.

[0140] The reverse state is the state where the user wears the device first and then powers it on, and then removes the device after powering on. The proximity state and the distance state are the states where the user powers on the device first and then wears it, and then the user puts on the device after powering on, putting the device in the proximity state. Then, the user removes the device while it is in the proximity state, and the device changes from the proximity state to the distance state.

[0141] In this embodiment of the disclosure, after the wearable device is powered on, the capacitive sensor is enabled to initialize and then enter a normal working state, providing accurate and effective detection values ​​for the timely screen-off of the display.

[0142] In some optional embodiments of this disclosure, controlling the display screen of a wearable device to turn on may include: controlling the display screen to display pre-configured initial display content.

[0143] Determining whether a wearable device meets the screen-off condition based on information about changes in the display content of its screen can include: determining whether a wearable device meets the screen-off condition if the display content remains at the initial display content.

[0144] In some optional embodiments of this disclosure, the initial display content may be a pre-configured initial interface, images, or other content, and there is no specific limitation.

[0145] In some optional embodiments of this disclosure, if the displayed content remains the initial content, it indicates that the content displayed by the wearable device has not changed since it was powered on. This also suggests that the user is not wearing the wearable device, and the wearable device is in a static or relatively static state. Therefore, it can be determined that the wearable device meets the screen-off conditions, and screen-off can be controlled.

[0146] Figure 8 is a flowchart illustrating a method for controlling a wearable device provided in yet another exemplary embodiment of this disclosure.

[0147] In some optional embodiments of this disclosure, based on any of the above embodiments, as shown in FIG8, after controlling the display screen of the wearable device to turn off, the following further steps are included:

[0148] Step 240: Based on the detection value of the capacitive sensor on the wearable device, determine whether the wearable device meets the screen-on condition.

[0149] In some optional embodiments of this disclosure, since the detection value of the capacitive sensor can characterize the proximity of the wearable device to the user's skin, if the detection value increases again to indicate that the wearable device is in a proximity state again, it can be determined that the wearable device meets the screen-on condition. Therefore, it is possible to determine whether the wearable device meets the screen-on condition based on the detection value of the capacitive sensor.

[0150] Step 250: When the wearable device meets the screen-on conditions, control the display screen of the wearable device to turn on.

[0151] In some optional embodiments of this disclosure, when the wearable device meets the screen-on conditions, indicating that the user is wearing the wearable device again, the display screen of the wearable device can be controlled to light up, so that the user can see the corresponding display content as soon as they put it on, thereby improving the user experience.

[0152] Step 260: When the display screen is on, perform the step of determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device.

[0153] In some optional embodiments of this disclosure, after the screen lights up again, the device can continue to determine whether it meets the screen-off conditions based on the detection value of the capacitive sensor on the wearable device. If the screen-off conditions are met, the device can promptly control the screen to turn off, avoiding power consumption or screen burn-in. The specific method for determining whether the screen-off conditions are met can be found in the foregoing embodiments, and will not be repeated here.

[0154] In this embodiment of the disclosure, after the screen is turned off, it is still possible to determine whether the screen-on conditions are met based on the detection value of the capacitive sensor, so that the screen can be turned on in time every time the user wears the wearable device, thereby improving the user experience. After the screen is turned on, it is possible to detect in time that the user has taken off the wearable device to control the screen to turn off.

[0155] In some optional embodiments of this disclosure, after controlling the display screen of the wearable device to turn off, the method further includes: controlling the wearable device to turn on the screen if the detection value of the capacitive sensor is greater than a first threshold; and controlling the wearable device to turn off the screen if the detection value of the capacitive sensor is less than a second threshold.

[0156] In some optional embodiments of this disclosure, after the display screen is turned off, the detection value of the capacitive sensor can be continuously monitored, and the relationship between the detection value and a first threshold can be determined in real time or periodically. If the detection value is greater than the first threshold, it indicates that the wearable device has entered an proximity state, i.e., the user puts on the wearable device, and the screen of the wearable device is turned on so that the user can see the corresponding display content in a timely manner. After the screen is turned on, the detection value of the capacitive sensor continues to be monitored. If the detection value begins to fall below a second threshold, it indicates that the user removes the wearable device, and the display screen of the wearable device can be turned off to prevent screen burn-in.

[0157] In some optional embodiments of this disclosure, after each screen-off, the detection value of the capacitive sensor can be used to determine whether the screen-on condition is met. After the screen is on, the detection value of the capacitive sensor can be used to determine whether the screen-off condition is met. This process continues until the user turns off the wearable device.

[0158] In this embodiment of the disclosure, after triggering the screen off, the screen can be turned on promptly if the detection value of the capacitive sensor is greater than a first threshold, so that the screen can be turned on promptly every time the user wears the wearable device, thereby improving the user experience. After the screen is turned on, the display screen can be turned off promptly if the detection value of the capacitive sensor is less than a second threshold.

[0159] In some optional embodiments of this disclosure, FIG9 is a flowchart of a method for controlling a wearable device provided in an exemplary embodiment of this disclosure. As shown in FIG9, the process of the method may include the following steps:

[0160] Step 610: Power on the wearable device.

[0161] Step 620: The display screen lights up.

[0162] Step 630: Enable the capacitive sensor.

[0163] Step 640: Initialize the capacitive sensor. Proceed to at least one of the following steps: Step 6510 of Detection Logic 1, Step 6610 of Detection Logic 2, Step 6710 of Detection Logic 3, and Step 6810 of Detection Logic 4.

[0164] Step 6510: Determine whether the detection value of the capacitive sensor is greater than the first threshold. That is, determine whether the detection value of the capacitive sensor has increased to a level greater than the first threshold. If the detection value is not greater than the first threshold, repeat step 6510. If the detection value is greater than the first threshold, proceed to step 6520.

[0165] Step 6520: Keep the screen on.

[0166] Step 6530: Determine whether the detection value of the capacitive sensor is less than the second threshold. That is, while keeping the screen on, continuously check whether the detection value of the capacitive sensor decreases to less than the second threshold. If the detection value is not less than the second threshold, repeat step 6530. If the detection value is less than the second threshold, proceed to step 690 to trigger screen off.

[0167] Step 6610: Determine if the detection value of the capacitive sensor is less than the third threshold. That is, continuously check if the detection value of the capacitive sensor decreases to the third threshold. If the detection value is not less than the third threshold, repeat step 6610. If the detection value is less than the third threshold, proceed to steps 6620 and 690 to trigger screen off.

[0168] Step 6620: Initialize and calibrate the capacitive sensor.

[0169] It should be noted that steps 6620 and 690 are not in any particular order.

[0170] Step 6710: Enable the motion data-based detection algorithm. This involves starting the detection logic 3, which uses motion data to determine whether the wearable device meets the screen-off conditions.

[0171] Step 6720: Determine if the wearable device is stationary. This involves determining whether the wearable device is stationary based on motion data. If the wearable device is not stationary, keep the screen on and repeat step 6720. If the wearable device is stationary, proceed to steps 6730 and 690 to trigger screen off.

[0172] Step 6730: Disable the motion data-based detection algorithm. That is, stop detection logic 3.

[0173] It should be noted that steps 6730 and 690 are not in any particular order.

[0174] Step 6810: Enable the detection algorithm based on display content. This involves activating the detection logic that uses information about changes in the display content of the wearable device's screen to determine whether the wearable device meets the conditions for screen-off.

[0175] Step 6820: Determine if the wearable device is stationary. This involves determining whether the wearable device meets the screen-off condition based on changes in the displayed content. "Stationary" here can include absolute stillness and relative stillness. For example, if the wearable device is placed on a mobile platform such as a vehicle or airplane, and the displayed content does not change, it indicates that the wearable device is stationary relative to the mobile platform. If the wearable device is not stationary, the screen remains on and step 6820 is repeated. If the wearable device is stationary, proceed to steps 6830 and 690 to trigger screen-off.

[0176] Step 6830: The detection algorithm based on the displayed content is disabled. That is, detection logic 4 is stopped.

[0177] It should be noted that steps 6830 and 690 are not in any particular order.

[0178] Step 690: Trigger screen shutdown. Return to step 6510 of execution of detection logic 1.

[0179] The specific operations for each of the above steps can be found in the corresponding embodiments described above, and will not be repeated here.

[0180] After the wearable device is powered on and the screen is turned on, the initial detection of whether the screen-off condition is met can be performed using one or more of the detection logics 1, 2, 3 and 4 shown in the figure. After triggering the screen-off condition through any detection logic, the system returns to detection logic 1 and performs subsequent screen-on and screen-off control through logic 1.

[0181] In some optional embodiments, detection logic 1, detection logic 2, detection logic 3, and detection logic 4 can be executed in parallel, and the determination of whether to trigger screen off is based on the combined judgment results of the four detection logics. For example, if at least one detection logic determines that the screen off condition is met, screen off can be triggered to ensure timely screen off.

[0182] In some optional embodiments, the four detection logics can be partially executed in parallel, or executed sequentially according to certain triggering conditions. For example, detection logic 1 and detection logic 2 can be executed in parallel to ensure timely screen-off in both cases where the user wears the device before powering on and before wearing it. As another example, detection logic 3 can be enabled first, and if detection logic 3 determines that the wearable device is not stationary, detection logic 4 can be further enabled to determine whether the screen-off condition is met. The specific combination of the four detection logics is not limited.

[0183] In some optional embodiments, a method for controlling a wearable device is provided, the method comprising: when a user wears the wearable device before powering it on, controlling the display screen of the wearable device to light up in response to powering on the wearable device; determining whether the wearable device meets the screen-off condition based on the detection value of a capacitive sensor on the wearable device; and controlling the display screen of the wearable device to turn off when the screen-off condition is detected.

[0184] In some optional embodiments, a method for controlling a wearable device is provided, the method comprising: in the case that the wearable device is powered on first and then the user wears the wearable device, in response to the power-on of the wearable device, controlling the display screen of the wearable device to turn on; determining whether the wearable device meets the screen-off condition based on the detection value of the capacitive sensor on the wearable device and the motion data of the wearable device; and controlling the display screen of the wearable device to turn off when the screen-off condition is detected.

[0185] In some optional embodiments, a method for controlling a wearable device is provided. This method may include the steps of the two methods described above. When the user wears the wearable device before powering it on, the following steps are performed: in response to powering on the wearable device, controlling the display screen of the wearable device to turn on; determining whether the wearable device meets the screen-off condition based on the detection value of a capacitive sensor on the wearable device; and if the screen-off condition is met, controlling the display screen of the wearable device to turn off. When the wearable device is powered on before the user wears it, the following steps are performed: in response to powering on the wearable device, controlling the display screen of the wearable device to turn on; determining whether the wearable device meets the screen-off condition based on the detection value of a capacitive sensor on the wearable device and motion data of the wearable device; and if the screen-off condition is met, controlling the display screen of the wearable device to turn off.

[0186] In some optional embodiments, step 6530 can be step 6530', which includes determining whether the detection value of the capacitive sensor is less than a second threshold, as defined in step 6530, and determining whether the wearable device is stationary, as defined in step 6720. If both conditions are met, the process proceeds to step 690 to trigger screen off. It is understood that in embodiments related to this solution, the motion data-based detection algorithm is always enabled.

[0187] In related technologies, a capacitive sensor is typically used to detect when a user is wearing a head-mounted display device, triggering the device's screen to light up and then keeping it lit until the user turns it off. This method is difficult to adapt to various application scenarios of head-mounted displays, such as the complex scenarios mentioned in this article, and therefore it is difficult to control the screen's on / off state.

[0188] In this embodiment, the display screen can be turned on immediately after the wearable device is powered on. Then, the system uses the detection values ​​from the capacitive sensor, motion data of the wearable device, and changes in the displayed content to determine whether a screen-off operation is needed. This method is applicable to different application scenarios of wearable devices, such as scenarios where the user wears the device before powering on, or vice versa. It can accurately detect whether the user is wearing the wearable device, improving the accuracy of wear detection.

[0189] The embodiments or optional examples disclosed herein can be implemented individually or in any combination without conflict. The specific implementation can be set according to actual needs, and this disclosure does not limit it.

[0190] Any of the methods for controlling wearable devices provided in this disclosure can be executed by any suitable device with data processing capabilities, including but not limited to: terminal devices and servers. Alternatively, any of the methods for controlling wearable devices provided in this disclosure can be executed by a processor, such as by a processor executing any of the methods for controlling wearable devices mentioned in this disclosure by calling corresponding instructions stored in memory. Further details will not be elaborated upon below.
