[0025] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0026] The flowcharts shown in the drawings are only illustrative, not necessarily including all the contents and operations / steps, and not necessarily executed in the described order. For example, some operations / steps can be decomposed, combined or partially merged, so that the actual execution order can be changed according to the actual situation.

[0027] The present application provides a boot and standby wake-up system AR glasses.

[0028] Some embodiments of the present application will be described in detail below with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0029] Please refer to Figure 1 , Figure 1 The structure diagram of a boot and standby wake-up system provided by an embodiment of the present application.

[0030] As shown in Figure 1 , the present application provides a boot and standby wake-up system, which comprises:

[0031] A display module, the display module comprises an optical engine and a waveguide lens, the optical engine and the waveguide lens are correspondingly arranged, and the optical engine is used to project image information to the waveguide lens after receiving a boot signal and a standby wake-up signal;

[0032] An inertial measurement module, the inertial measurement module is used to obtain motion state change information;

[0033] A first control module, the first control module is electrically connected with the inertial measurement module and the optical engine, and is used to respond to the motion state change information in the shutdown or standby state, and generate a boot signal and a standby wake-up signal when the motion state change information exceeds a first preset threshold;

[0034] A power module, the power module is connected with the optical engine, the inertial measurement module and the first control module, and is used to supply power to the optical engine, the inertial measurement module and the first control module.

[0035] Exemplarily, the booting and standby wake-up system provided by the embodiments of the present application can be used on AR glasses, of course, is not limited thereto, and can also be applied to other smart devices, such as a smart helmet. Taking AR glasses as an example, the display module emits visible light through an optical engine, and the visible light emitted by the optical engine is totally reflected and transmitted to the human eye through the waveguide lens, so that the user wearing the AR glasses can observe the preset virtual image. However, the display module has a large power consumption, and in the case that the user does not use the AR glasses for a long time, the display module will stop displaying the virtual image until the smart glasses enter the wake-up state; since the user usually has the action of picking up and unfolding the legs of the AR glasses before wearing the AR glasses, the AR glasses generate certain motion state change information, and the motion state change information obtained by the inertial measurement module is used to determine whether the user has the action of picking up and wearing the AR glasses, and then it is determined whether the display module of the AR glasses needs to be woken up, thereby improving the intelligence and rationality of the booting and standby wake-up system.

[0036] Exemplarily, the number of the inertial measurement module is not limited, and the number of the inertial measurement module can be one or more. The inertial measurement module can be an inertial measurement unit (IMU). Specifically, the inertial measurement module includes an acceleration sensor and an angular velocity sensor, the acceleration sensor is used to measure the linear acceleration of an object in three spatial axes, and the angular velocity sensor is used to measure the angular velocity of the object around three spatial axes, so as to obtain the motion state change information of the object.

[0037] Exemplarily, since the inertial measurement module has extremely low power consumption, it can continuously monitor the motion data without causing a large consumption of the AR glasses power even in the standby state of the AR glasses.

[0038] In some embodiments, the inertial measurement module includes an acceleration sensor and a gyroscope, the first preset threshold includes a first acceleration threshold and / or a first angular velocity threshold, the value range of the first acceleration threshold is 120 mg-2g, and the value range of the first angular velocity threshold is ± 15-± 125 dps.

[0039] Exemplarily, the first control module can determine whether to send a booting signal and a standby wake-up signal to the display module according to the first preset threshold. Since the inertial measurement module can measure the acceleration and angular velocity of an object, the first preset threshold can include at least one of a first acceleration threshold and a first angular velocity threshold.

[0040] Specifically, the user can set the sensitivity of standby wake-up according to actual needs. When the user needs high sensitivity, for example, in the scenario of reading in a study, the system for starting up and standby wake-up can only judge the motion state change information through the first acceleration threshold or the first angular velocity threshold, and when the motion state change information meets either of the first acceleration threshold and the first angular velocity threshold, the first control module generates the start-up signal and the standby wake-up signal. Conversely, when the user needs low sensitivity, for example, in the scenario of running, swimming and the like, the system for starting up and standby wake-up can judge the motion state change information through the first acceleration threshold and the first angular velocity threshold, and only when the motion state change information meets both the first acceleration threshold and the first angular velocity threshold, the first control module generates the start-up signal and the standby wake-up signal.

[0041] The values of the first acceleration threshold and the first angular velocity threshold can be determined according to the sensitivity set by the user, wherein the value of the first acceleration threshold is between 120 mg and 2 g, and the value of the first angular velocity threshold is between ± 15 and ± 125 dps (degree per second).

[0042] In some embodiments, the first preset threshold further includes a first time threshold, and the first time threshold is 10 seconds.

[0043] For example, in order to improve the accuracy of standby wake-up and avoid the device from being mistakenly woken up when it moves strongly in a short time, the first preset threshold further includes a first time threshold, which can be 10 seconds for example. The first control module generates the start-up signal and the standby wake-up signal only when the duration of the motion state change information exceeding the first preset threshold is greater than 10 seconds.

[0044] Please refer to Figure 2 , Figure 2 A structural schematic diagram of an intelligent glasses is provided for an embodiment of the present application.

[0045] As Figure 2 shown, in some embodiments, the system for starting up and standby wake-up further includes a second control module, which is connected with the power module, the inertial measurement module and the optical-mechanical-electrical module, and is used for responding to the motion state change information in the start-up state and generating a shutdown signal or a standby hibernate signal when the motion state change information does not exceed a second preset threshold.

[0046] Exemplarily, the booting and standby wake-up system provided by the embodiment of the present application can also control the display module to enter the shutdown state or the standby hibernation state through the second control module. Specifically, the light engine in the display module stops projecting image information to the waveguide lens after receiving the shutdown signal or the standby hibernation signal of the second control module.

[0047] Exemplarily, in the case that the motion state change information detected by the inertial measurement module indicates that the device is relatively static, the second control module generates the shutdown signal and the standby hibernation signal, and the display module stops projecting image information to the waveguide lens after receiving the shutdown signal or the standby hibernation signal.

[0048] In some embodiments, the second preset threshold is a second acceleration threshold and a second angular velocity threshold, the second acceleration threshold is 100 mg, and the second angular velocity threshold is ±10 dps.

[0049] Exemplarily, the second preset threshold includes a second acceleration threshold for judging the acceleration information detected by the inertial measurement module and a second angular velocity threshold for judging the angular velocity information detected by the inertial measurement module. The second control module generates the shutdown signal and the standby hibernation signal to control the display module to stop projecting image information to the waveguide lens in the case that the motion state change information meets the second acceleration threshold and the second angular velocity threshold at the same time, thereby avoiding the display module from frequently entering hibernation and causing poor user experience.

[0050] Specifically, the second control module generates the shutdown signal or the standby hibernation signal in the case that the acceleration detected by the inertial measurement module is less than 100 mg and the angular velocity is less than ±10 dps.

[0051] In some embodiments, the second preset threshold further includes a second time threshold, and the second time threshold is 30 seconds.

[0052] Exemplarily, in order to avoid the device from frequently entering the shutdown state and the standby hibernation state, the second preset threshold further includes a second time threshold, and the second control module generates the shutdown signal and the standby hibernation signal only in the case that the duration of the motion state change information exceeding the second preset threshold is greater than the second time threshold.

[0053] Specifically, the second control module generates the shutdown signal or the standby hibernation signal in the case that the duration of the acceleration detected by the inertial measurement module being less than 100 mg and the angular velocity being less than ±10 dps is greater than 30 seconds.

[0054] Please refer to Figure 3 , Figure 3 FIG. 1 is a structural schematic diagram of an intelligent glasses provided by an embodiment of the present application.

[0055] AsFigure 3 In some embodiments, the power-on and standby wake-up system further comprises a touch control module connected to the first control module, the second control module, and the power module, configured to generate a first touch control signal in response to a touch control operation on a touch area when the motion state change information exceeds the first preset threshold value; the touch control signal is a control signal other than the power-on signal, the power-off signal, the standby sleep signal, and the standby wake-up signal.

[0056] For example, the user can also control the device through the touch control module. For example, the user can perform single-click, double-click, swipe, long press, and other operations on the touch control module, so that the touch control module generates and sends a first touch control signal to any one of the first control module and the second control module, so that the first control module and the second control module perform corresponding control operations.

[0057] The touch control module can obtain the touch control operation of the user based on a capacitive sensor. When a human body touches the surface of the capacitive sensor, the capacitance of the capacitive sensor will change due to the conductivity of the human body. By detecting the change in capacitance and converting it into an electrical signal output, the function of touch control is realized.

[0058] In some embodiments, the power-on and standby wake-up system further comprises a sensitivity adjustment module, the sensitivity adjustment module comprising a plurality of sensitivity levels, the plurality of sensitivity levels corresponding to different values of the first acceleration threshold value and / or the first angular velocity threshold value.

[0059] and / or a parameter adjustment module configured to obtain the motion state change information and dynamically adjust the first acceleration threshold value and / or the first angular velocity threshold value based on the motion state change information.

[0060] For example, different values of the first acceleration threshold value and / or the first angular velocity threshold value are set for each sensitivity level, and the user can adjust the first acceleration threshold value and / or the first angular velocity threshold value by adjusting the sensitivity level. Because different users have different habits when using the device, in order to avoid frequent false wake-ups or to make the device not respond when standby wake-up is needed, the user can adjust the values of the first acceleration threshold value and / or the first angular velocity threshold value according to their own usage habits by adjusting the sensitivity level. Specifically, for users who move lightly, the values of the first acceleration threshold value and / or the first angular velocity threshold value can be appropriately reduced to make it easier to wake up the device; for users who move more, the values of the first acceleration threshold value and / or the first angular velocity threshold value can be increased to avoid false wake-ups of the device.

[0061] Exemplarily, the values of the first acceleration threshold and / or the first angular velocity threshold can also be dynamically adjusted by the parameter adjustment module according to the use habits of the user. For example, when the user first wears the AR glasses, the motion information of the user during normal use can be obtained through the inertial measurement module within a certain time period, and the values of the first acceleration threshold and / or the first angular velocity threshold matched with the use habits of the user can be determined according to the motion information. In subsequent use, the parameter adjustment module can also adjust the values of the first acceleration threshold and / or the first angular velocity threshold according to the changes in the use habits of the user every certain period of time, so as to ensure that the wake-up and sleep functions of the device can always maintain the best performance and effect.

[0062] Exemplarily, the start-up and standby wake-up system provided by the embodiments of the present application improves the flexibility and accuracy of the start-up and standby wake-up system by setting the adjustable first preset threshold.

[0063] The embodiments of the present application also provide an AR glass, comprising a frame, a temple, and the start-up and standby wake-up system according to any one of the embodiments of the present application; the inertial measurement module is an inertial measurement unit, and the inertial measurement unit is fixedly assembled in any one of the frame, the temple, and the space formed by the frame and the temple.

[0064] Exemplarily, the start-up and standby wake-up system provided by the embodiments of the present application can be installed in the AR glasses. Specifically, the light machine in the start-up and standby wake-up system can be installed in the temple of the AR glasses, and the waveguide lens in the waveguide lens can be installed in the frame of the AR glasses.

[0065] Exemplarily, through the start-up and standby wake-up system provided by the embodiments of the present application, the user can wake up the display module of the AR glasses when moving or wearing the AR glasses, which improves the convenience of standby wake-up of the AR glasses and thus improves the use experience of the AR glasses.

[0066] In some embodiments, the AR glasses comprise two inertial measurement units, and the two inertial measurement units are fixedly assembled in any two of the space formed by the frame, the space formed by the temple, and the space formed by the frame and the temple.

[0067] Exemplarily, through the two inertial measurement units, the motion state change information of the AR glasses is detected, for example, when the motion state change information of the two inertial measurement units both meet the first preset threshold, the start-up signal and the standby wake-up signal are generated, the light machine is controlled to project the image information to the waveguide lens, and the accuracy of standby wake-up is improved.

[0068] In some embodiments, the inertial measurement unit comprises an acceleration sensor and an angular velocity sensor, which are fixedly assembled in the frame, the temple, or any accommodating space formed by the frame and the temple.

[0069] For example, the inertial measurement unit obtains acceleration information of the AR glasses through the acceleration sensor and obtains angular velocity information of the AR glasses through the angular velocity sensor, thereby improving comprehensiveness of the motion state change information. In this way, the inertial measurement unit can be a 6-axis inertial measurement unit, that is, the acceleration sensor is a 3-axis acceleration sensor and the angular velocity sensor is a 3-axis angular velocity sensor, thereby improving accuracy of the motion state change information.
