Description

[0002] As wireless control devices, remote controls typically emit specific signals (e.g., infrared, radio waves) to remotely operate electronic devices (e.g., televisions), thus providing convenience for controlling electronic devices. However, remote controls are generally battery-powered and lack a switching component. After leaving the factory, the remote control remains continuously powered (i.e., the battery continuously supplies power to the components included in the remote control). This continuous power supply can cause the remote control's battery to deplete rapidly. Therefore, users may need to frequently replace batteries or recharge the remote control, leading to a decrease in user satisfaction with its use.

Capacitor 1414 can stabilize the voltage between the base and emitter of switching element 1412.

[0070] Processor 110 can output an enable signal EN2 with a high voltage or a low level to turn on or off the switching circuit 141. In response to processor 110 outputting the low-level enable signal EN2, the base-emitter voltage difference of switching element 1412 may not exceed a threshold voltage, and switching element 1412 may be turned off. When switching element 1412 is turned off, the source voltage of switching element 1411 may be equal to the gate voltage. In this case, the source-gate voltage difference of switching element 1411 may not exceed a threshold voltage, and switching element 1411 may be turned off. Power supply assembly 160 cannot supply power to positioning assembly 140.

[0071] In response to the processor 110 outputting a high-level enable signal EN2, the base-emitter voltage difference of the switching element 1412 can exceed the threshold voltage, allowing the switching element 1412 to conduct. When the switching element 1412 is on, the gate voltage of the switching element 1411 can drop significantly, while the source voltage of the switching element 1411 can remain unchanged. In this case, the source-gate voltage difference of the switching element 1411 can exceed the threshold voltage, allowing the switching element 1411 to conduct. The power supply assembly 160 can then supply power to the positioning assembly 140.

[0072] The remote control 100 shown in Figure 1A may include an absolute pointing remote control. The absolute pointing remote control can use absolute pointing interaction technology to directly and precisely align the remote control's pointing with the target, eliminating the need to repeatedly switch between different icons, thus greatly improving operational convenience. The absolute pointing interaction technology can perform attitude calculation based on motion data detected by the motion detection component 120 and positioning calculation based on position data detected by the positioning component 130. By fusing motion and position data, the absolute pointing remote control can enable menu selection by pointing, eliminating the need for the up, down, left, and right buttons of a regular remote control, further enhancing the user experience. For example, users can use the absolute pointing remote control to perform interactive methods such as swiping, dragging, and selecting on the screen of the controlled electronic device, similar to those found on mobile phones, achieving a "point-and-see" touch control effect. However, those skilled in the art will understand that the absolute pointing remote control is merely an example, and the remote control 100 according to this disclosure may also include other types of remote controls; this disclosure is not limited to these.

[0073] Figure 2 shows a flowchart of a control method for a remote controller according to an embodiment of the present disclosure. As shown in Figure 2, the control method 200 includes steps S220-S230.

[0074] In step S210, the processor 110 can determine whether the remote control 100 is in a stationary state via the motion detection component 120. Whether the remote control 100 is in a stationary state can, to some extent, indicate or imply whether the remote control 100 is being used by a user. According to one embodiment of this disclosure, the remote control 100 being in a stationary state may indicate that the remote control 100 is not currently being used by a user; for example, the remote control 100 may be placed on furniture such as a tabletop. According to one embodiment of this disclosure, the remote control 100 being in a non-stationary state may indicate that the remote control 100 is currently being used by a user; for example, the remote control 100 may be being manipulated by a user to control an electronic device such as a television.

[0075] In step S220, the processor 110 may activate the light detection component 130 in response to the remote control 100 being in a stationary state to determine whether the ambient light is below a brightness threshold. Whether the ambient light is below the brightness threshold can, to some extent, indicate or suggest whether the remote control 100 is in a normal or abnormal working environment. A normal working environment may indicate that the probability of the user using the remote control 100 is relatively high, while an abnormal working environment may indicate that the probability of the user using the remote control 100 is relatively low. The controlled electronic device may include a television or a monitor, etc. According to one embodiment of this disclosure, if the ambient light detected by the light detection component 130 is not below the brightness threshold, it can be indicated that the remote control 100 is in a normal working environment. A normal working environment may include the controlled electronic device being powered on. For example, the backlight component of the controlled electronic device may be on, so the user is likely to use the remote control 100 to operate it. According to one embodiment of this disclosure, if the ambient light detected by the light detection component 130 is below the brightness threshold, it can be indicated that the remote control 100 is in an abnormal working environment. An abnormal working environment may include the controlled electronic device being powered off. For example, an abnormal operating environment could instruct the backlight assembly of the controlled electronic device to be turned off and other lighting devices (e.g., room lights) to be turned off, so the user does not need to use the remote control 100. An abnormal operating environment could include the controlled electronic device being stored in a container. For example, an abnormal operating environment could instruct the remote control 100 to be stored in a container such as a drawer, so the user cannot use the remote control 100.

[0076] In step S230, the processor 110 may, in response to ambient light levels below a brightness threshold and the remote control 100 being stationary, control the remote control 100 to enter a first low-power mode. In the first low-power mode, the processor 110 may disable a first function of the motion detection component 120, which includes the motion detection component 120 waking up the processor 110 from sleep mode based on the remote control 100 being in a non-stationary state. When the remote control 100 is stationary and the ambient light is below the brightness threshold, the remote control 100 may not be used by the user for an extended period. For example, a user may place the remote control 100 on furniture while resting at night and turn off the controlled electronic devices and other lighting. Alternatively, a user may store the remote control 100 in a drawer. In these cases, the remote control 100 may enter the first low-power mode. Since the user will not use the remote control 100 for a short period, the first function of the motion detection component 120 can be disabled, thereby further saving power and increasing standby time.

[0077] Figure 3 shows a flowchart of another control method for a remote controller according to an embodiment of the present disclosure. As shown in Figure 3, the control method 300 includes steps S310-S390.

[0078] In step S310, hardware initialization can be performed on the remote controller 100. According to one embodiment of this disclosure, hardware initialization may include disconnecting the communication connection between the processor 110 and the controlled electronic device, disabling the motion detection component 120, disabling the light detection component 130, and disabling the positioning component 140.

[0079] In step S320, a first low-power state can be entered. According to an embodiment of this disclosure, when the remote controller 100 is manufactured, its processor 110 and the controlled electronic device can be in a state of disconnected communication to save power. The processor 110 can send control signals to the motion detection component 120 to disable a first function and a second function of the motion detection component 120. For example, the processor 110 can send a control word 1 to disable the first function and a control word 2 to disable the second function to the motion detection component 120 via SPI. The processor 110 can disable at least one of the light detection component 130 and the positioning component 140. The processor 110 can send an enable signal EN1 with a low level to the switching circuit 131 and an enable signal EN2 with a low level to the switching circuit 141 to disconnect the switching circuits 131 and 141, thereby de-energizing the light detection component 130 and the positioning component 140.

[0080] In step S330, it can be determined whether a power-on operation should be performed. According to one embodiment of this disclosure, the power-on operation can be performed by operating the user input component 150. For example, the power-on operation can be performed by pressing one or more buttons in the user input component 150, but those skilled in the art will understand that the power-on operation can also be performed in other ways. In response to not performing a power-on operation, the remote control 100 can remain in the first low-power mode.

[0081] In response to performing the power-on operation, the process can proceed to step S340. In step S340, the remote control can enter the normal operation mode. According to an embodiment of this disclosure, in the normal operation mode, the processor 110 can enable the communication function and establish a communication connection with the controlled electronic device. For example, the processor 110 can enable the Bluetooth protocol stack, so that the Bluetooth function of the remote control 100 is in normal broadcast state. The user can start the controlled electronic device and establish a communication connection between the remote control 100 and the controlled electronic device. The processor 110 can determine whether the remote control 100 has established a communication connection with the controlled electronic device. If the communication connection has not been established, the processor 110 can try to connect again. In response to determining that the remote control 100 has established a communication connection with the controlled electronic device, the processor 110 can enable the first and second functions of the motion detection component 120 and the positioning component 140. According to an embodiment of this disclosure, the processor 110 can instruct the motion detection component 120 to enable the first function using control word 1 and the motion detection component 120 to enable the second function using control word 2. According to one embodiment of this disclosure, the processor 110 may send an enable signal EN1 with a high level to the switching circuit 141, thereby powering the positioning component 140 to enable the positioning component 140 to perform a positioning function.

[0082] In normal operating mode, the processor 110 can receive motion data from the motion detection component 120 and position data from the positioning component 140, and transmit the motion data and position data to the controlled electronic device via a communication connection. The controlled electronic device, using a positioning fusion algorithm, can calculate the position pointed to by the remote control 100 and display the cursor on its screen in real time. In this way, the remote control 100 can be used to point at the device to select menus, and the menus can be opened and confirmed by operating the user input component 150 of the remote control 100.

[0083] In step S350, it can be determined whether a stationary indication appears in the motion data. In normal operating mode, the motion detection component 120 can continuously detect the motion data of the remote controller 100. According to an embodiment of this disclosure, if a stationary indication appears in the motion data of the remote controller 100 at at least one time point detected by the motion detection component 120, the processor 110 can determine that the remote controller is in a candidate stationary state. Specifically, the stationary indication may include: (1) the difference between the Z-axis acceleration and the gravitational acceleration is less than an acceleration threshold; (2) the difference between the X-axis acceleration and zero and the difference between the Y-axis acceleration and zero is less than an acceleration threshold; (3) the difference between the X-axis angular velocity and zero, the difference between the Y-axis angular velocity and zero, and the difference between the Z-axis angular velocity and zero is less than an angular velocity threshold. That is, the stationary indication may indicate that the Z-axis acceleration of the remote controller 100 is close to gravitational acceleration, and the X-axis acceleration, Y-axis acceleration, and X-axis, Y-axis, and Z-axis angular velocities are very small. In response to the absence of a stationary indication in the motion data, the process can proceed to step S340. The remote control 100 can be in normal operation mode in step S340. In response to a stationary indication appearing in the motion data, the process can proceed to step S360.

[0084] In step S360, a confirmation process for the stationary state can be performed. According to an embodiment of this disclosure, the processor 110 can confirm the candidate stationary state as a stationary state by performing a confirmation process in response to the remote controller being in a candidate stationary state.

[0085] The verification process 360 will be described in detail with reference to FIG4. FIG4 shows a flowchart of a verification process according to an embodiment of the present disclosure. As shown in FIG4, the verification process 360 may include steps S361 to S366.

[0086] In step S361, the first root mean square error of the X-axis acceleration, Y-axis acceleration and Z-axis acceleration and the first root mean square error of the X-axis angular velocity, Y-axis angular velocity and Z-axis angular velocity during the first time period can be calculated based on the following equations (1)-(6).

[0087] Among them, g z The mean square error (μ) is the variance of the N acceleration data points along the Z-axis of the motion detection component 120 during the first time period. gz This is the average value of N acceleration data points along the Z-axis.

[0088] Among them, g x Let μ be the mean square error of the N acceleration data points along the X-axis of the motion detection component 120 during the first time period. gx This is the average value of N acceleration data points along the X-axis.

[0089] Among them, g y The mean square error (μ) is the variance of the N acceleration data points along the Y-axis of the motion detection component 120 during the first time period. gy This is the average of N acceleration data points along the Y-axis.

[0090] ω x The mean square error (μ) is the variance of the N angular velocity data in the X-axis direction of the motion detection component 120 during the first time period. ωx This is the average value of N angular velocity data points along the X-axis.

[0091] ω y The mean square error (μ) of the N angular velocity data in the Y-axis direction of the motion detection component 120 during the first time period is given by the expression μ. ωy This is the average of N angular velocity data points along the Y-axis.

[0092] ω z The mean square error (μ) of the N angular velocity data in the Z-axis direction of the motion detection component 120 during the first time period is given by the expression μ. ωz This is the average value of N angular velocity data points along the Z-axis.

[0093] In step S362, it can be determined whether the first acceleration mean square error is less than an acceleration mean square error threshold, and whether the first angular velocity mean square error is less than an angular velocity mean square error threshold. According to an embodiment of this disclosure, it can be determined whether the first acceleration mean square errors of the X, Y, and Z axes are each less than an acceleration mean square error threshold Δg1, and whether the first angular velocity mean square errors of the X, Y, and Z axes are each less than an angular velocity mean square error threshold Δω. That is, g is considered less than the following conditions are met: z <Δg1、g x <Δg1、g z <Δg1、ω z <Δω、ω x <Δω、ω y If Δω is less than 0, the process can proceed to S363. If any of the above conditions are not met, the process can proceed to S365. In step S365, it can be determined that the remote control is in a non-stationary state.

[0094] In step S363, after a predetermined time interval, the second root mean square error of the X-axis acceleration, Y-axis acceleration, and Z-axis acceleration, as well as the second root mean square error of the X-axis angular velocity, Y-axis angular velocity, and Z-axis angular velocity during the second time interval, can be calculated. The predetermined time interval can be a few seconds, a few minutes (or longer or shorter). The process of calculating the root mean square error of acceleration and the root mean square error of angular velocity can be referred to the above equations (1)-(6), and will not be repeated here to avoid redundancy.

[0095] In step S364, it can be determined whether the second acceleration mean square error is less than an acceleration mean square error threshold, and whether the second angular velocity mean square error is less than an angular velocity mean square error threshold. According to an embodiment of this disclosure, it can be determined whether the second acceleration mean square errors of the X, Y, and Z axes are each less than an acceleration mean square error threshold, Δg1, and whether the second angular velocity mean square errors of the X, Y, and Z axes are each less than an angular velocity mean square error threshold, Δω. The process of determining whether the second acceleration mean square error is less than the acceleration mean square error threshold and whether the second angular velocity mean square error is less than the angular velocity mean square error threshold is similar to the process of determining whether the first acceleration mean square error is less than the acceleration mean square error threshold and whether the first angular velocity mean square error is less than the angular velocity mean square error threshold in step S362, and will not be repeated here to avoid redundancy. When the second acceleration mean square error is less than the acceleration mean square error threshold and the second angular velocity mean square error is less than the angular velocity mean square error threshold, the process can proceed to step S366. When the second acceleration mean square error is not less than the acceleration mean square error threshold, and the second angular velocity mean square error is not less than the angular velocity mean square error threshold, the process can proceed to step S365. In step S365, it can be determined that the remote control is in a non-stationary state. In step S366, it can be determined that the remote control is in a stationary state.

[0096] In response to the determination in step S365 that the remote control is in a non-stationary state, referring back to Figure 3, the process can proceed to step S340, where the remote control can continue to remain in normal operating mode.

[0097] In response to determining in step S366 that the remote control is in a stationary state, referring back to Figure 3, the process can proceed to step S370. In step S370, the light detection component 130 can be activated to determine whether the ambient light is below a brightness threshold. According to one embodiment of this disclosure, the processor 110 can send an enable signal EN2 with a high level to the switching circuit 131, thereby powering the light detection component 130 to enable the positioning component 140 to perform the light detection function. The light detection component 130 can determine whether the ambient light is below a brightness threshold. According to one embodiment of this disclosure, in response to the light detection component 130 determining that the ambient light is below the brightness threshold, the light detection component 130 can send a signal with a low level to the processor 110 via the I / O interface.

[0098] In response to the processor 110 determining that the ambient light is below a brightness threshold, the process can proceed to step S320, and the remote control can enter the first low-power mode. When the user needs to use the remote control 100 again, the user can perform the power-on operation in step S330 again.

[0099] In response to the processor 110 determining that the ambient light is not lower than a brightness threshold, the process can proceed to step S380. In step S380, in response to the ambient light not being lower than the brightness threshold and the remote control being in a stationary state, the processor 110 can control the remote control 100 to enter a second low-power mode. In the second low-power mode, the first function of the motion detection component 120 can be enabled and the second function can be disabled. In the second low-power mode, at least one of the light detection component 130 and the positioning component 140 can be disabled. In the second low-power mode, the processor 110 of the remote control 100 can be in a sleep mode, and the processor 110 in the second low-power mode can increase the interval of communication between the processor 110 and the electronic device controlled by the remote control 100 and / or reduce the duration of communication. According to an embodiment of this disclosure, the processor 110 can send control signals to the motion detection component 120 to enable the first function and disable the second function. For example, the processor 110 can send a control word 1 to enable the first function and a control word 2 to disable the second function to the motion detection component 120 via SPI. Processor 110 can send a low-level enable signal EN1 to switch circuit 131 and a low-level enable signal EN2 to switch circuit 141 to disconnect switch circuits 131 and 141, thereby de-energizing the light detection component 130 and the positioning component 140. As an example, when processor 110 communicates with a notified electronic device using the Bluetooth protocol, the Bluetooth protocol stack in processor 110 can increase the broadcast interval or shorten the broadcast duration.

[0100] Since the first function of the motion detection component 120 is enabled, the motion detection component 120 detects whether the remote control is moved, thereby determining in step S390 whether the remote control 100 is in a stationary state. In response to the remote control 100 being in a stationary state, the process can proceed to S380, where the remote control 100 continues to maintain the second low-power mode. In response to the remote control 100 being in a non-stationary state, the process can proceed to S340, where the remote control 100 can switch to a normal operating mode. As mentioned above, the remote control 100 is more likely to be used when it is in a normal operating environment. If the ambient light detected by the light detection component 130 is not lower than the brightness threshold, it can be indicated that the remote control 100 is in a normal operating environment. A normal operating environment may include the controlled electronic device being powered on. For example, the backlight component of the controlled electronic device may be on, in which case the stationary or unused state of the remote control 100 may be temporary. For example, a user may use the remote control 100 to operate the device and then watch content played on a television or monitor without using the remote control 100 during the viewing period. In this case, the remote control 100 may be in the second low-power mode. After a user has watched the content for a period of time, the user can operate the remote control 100 again to, for example, switch or adjust the content being played. When the user operates the remote control 100, the remote control 100 is not in a stationary state, so the remote control 100 can enter the normal operation mode through the wake-up signal sent by the motion detection component 120. Table 1 below shows the enabling and disabling of the corresponding components of the remote control 100 in different modes.

[0101] Table 1

[0102] Figure 5 shows a schematic diagram of another remote control according to an embodiment of the present disclosure. The remote control 500 in Figure 5 differs from the remote control 100 in Figure 1A in that the remote control 500 also includes a touch detection component 510 and a switching circuit 511. Components identical to those in Figure 1A in Figure 5 will not be described again to avoid redundancy.

[0103] Touch detection component 510 may include one or more of an infrared touch sensor, a capacitive touch sensor, a resistive touch sensor, an ultrasonic touch sensor, and an optical touch sensor. In an embodiment where touch detection component 510 is an infrared touch sensor, the infrared touch sensor may be based on the temperature difference between a thermally radiating object and its surrounding environment. For example, a user's human body can radiate infrared radiation, which can be received by the infrared touch sensor when the human body approaches or touches the remote control 500. The infrared touch sensor may include a pair of infrared emitting diodes and infrared receiving diodes. The infrared emitting diodes emit infrared radiation, while the infrared receiving diodes receive infrared radiation emitted by the human body. When a human body approaches or touches the remote control 500, the emitted infrared radiation is absorbed or reflected by the human body, causing the received infrared signal to weaken. The receiving diodes can detect this signal change and convert it into an electrical signal output. Touch detection component 510 may receive electrical power from power supply component 160 via switching circuit 511. Touch detection component 510 can detect whether a user touches the remote control 500 and can send data indicating whether the remote control 500 is touched (e.g., held by the user) to processor 110 via an I / O interface. For example, in response to the touch detection component 510 detecting a user touch the remote control 500, the touch detection component 510 may send a low-level signal to the processor 110 via, for example, an I / O interface. In response to the touch detection component 510 not detecting a user touch the remote control 500, the touch detection component 510 may send a high-level signal to the processor 110 via, for example, an I / O interface.

[0104] The processor 110 can send an enable signal EN3 to the switching circuit 511 to turn it on or off. According to one embodiment of this disclosure, the processor 110 can send a high-level enable signal EN3 to turn on the switching circuit 511 to power the touch detection component 510, and can send a low-level enable signal EN3 to turn off the switching circuit 511 to power off the touch detection component 510. The structure of the switching circuit 511 can be similar to that of switching circuits 131 and 141, and will not be described again here to avoid redundancy.

[0105] Figure 6 shows a flowchart of another control method for a remote controller according to an embodiment of the present disclosure. As shown in Figure 6, the control method 600 includes steps S601 to S610. The control method 600 can be applied to the remote controller 500. Parts in Figure 6 that are the same as or similar to those in Figure 3 will not be described again.

[0106] In step S601, hardware initialization can be performed on the remote controller 500. According to one embodiment of this disclosure, hardware initialization may include disconnecting the communication connection between the processor 110 and the controlled electronic device, disabling the motion detection component 120, disabling the light detection component 130, disabling the positioning component 140, and disabling the touch detection component 510.

[0107] In step S602, a first low-power state can be entered. According to an embodiment of this disclosure, when the remote controller 500 is manufactured, its processor 110 and the controlled electronic device can be in a state of disconnected communication to save power. The processor 110 can send control signals to the motion detection component 120 to disable a first function and a second function of the motion detection component 120. For example, the processor 110 can send a control word 1 to disable the first function and a control word 2 to disable the second function to the motion detection component 120 via SPI. The processor 110 can disable at least one of the light detection component 130, the positioning component 140, and the touch detection component 510. The processor 110 can send a low-level enable signal EN1 to the switching circuit 131, a low-level enable signal EN2 to the switching circuit 141, and a low-level enable signal EN3 to the switching circuit 511 to disconnect the switching circuits 131, 141, and 511, thereby de-energizing the light detection component 130, the positioning component 140, and the touch detection component 510.

[0108] In step S603, it can be determined whether a power-on operation should be performed. According to one embodiment of this disclosure, the power-on operation can be performed by operating the user input component 150. For example, the power-on operation can be performed by pressing one or more buttons in the user input component 150, but those skilled in the art will understand that the power-on operation can also be performed in other ways. In response to not performing a power-on operation, the remote control 500 can remain in the first low-power mode.

[0109] In response to the power-on operation, the process can proceed to step S604. In step S604, the remote control can enter the normal operation mode. According to an embodiment of this disclosure, in the normal operation mode, the operation of the remote control 500 can be referred to the content of step S330 in Figure 3, which will not be repeated here.

[0110] In step S605, it can be determined whether a stationary indication appears in the motion data. A detailed description of the stationary indication can be found in step S350 of Figure 3. If no stationary indication appears in the motion data, the process can proceed to step S604. The remote control 500 can enter normal operation mode in step S604. If a stationary indication appears in the motion data, the process can proceed to step S606.

[0111] In step S606, in response to the remote controller 500 being in a candidate stationary state, the touch detection component 510 can be activated to detect whether the remote controller 500 has been touched. According to one embodiment of this disclosure, the processor 110 can send a high-level enable signal EN3 to the switching circuit 511, thereby powering the touch detection component 510 to perform the touch detection function. The touch detection component 510 can determine whether the user has touched the remote controller 500. According to one embodiment of this disclosure, in response to the touch detection component 510 determining that the user has touched the remote controller 500, the touch detection component 510 can send a low-level signal to the processor 110 via the I / O interface to indicate that the remote controller has been touched.

[0112] In response to the remote control 500 not being touched, the process can proceed to step S609. In step S609, the processor 110 can control the remote control 500 to enter a second low-power mode. A description of the second low-power mode can be found in the above description of FIG3. Furthermore, in the second low-power mode, the touch detection component 510 can be disabled. According to one embodiment of this disclosure, the processor 110 can send an enable signal EN3 with a low level to the switching circuit 511 to power off the touch detection component 510. In response to the remote control 500 being touched, the process can proceed to step S607.

[0113] In step S607, a confirmation process for the stationary state can be performed. The confirmation process can be referred to the description above of step S360 in Figure 3 and Figure 4. In response to determining in step S607 that the remote control is in a non-stationary state, the process can proceed to step S604, and the remote control can continue to operate in normal mode.

[0114] In response to determining in step S607 that the remote control is stationary, the process can proceed to step S608. In step S608, the light detection component 130 can be activated to determine whether the ambient light is below a brightness threshold. The process of determining whether the ambient light is below the brightness threshold can be referred to step S370 in Figure 3.

[0115] In response to the processor 110 determining that the ambient light is below the brightness threshold, the process can proceed to step S602, and the remote control can enter the first low-power mode. When the user needs to use the remote control 500 again, the user can perform the power-on operation in step S603 again.

[0116] In response to the processor 110 determining that the ambient light is not lower than a brightness threshold, the process can proceed to step S609. In step S609, in response to the ambient light not being lower than the brightness threshold and the remote control being in a stationary state, the processor 110 can control the remote control 500 to enter a second low-power mode. A description of steps S609 and S610 can be found in the description of steps S380 and S390 in Figure 3.

[0117] Figure 7 illustrates a circuit for performing a first switching operation and a second switching operation according to an embodiment of the present disclosure. Figure 8 illustrates a circuit for performing a second switching operation according to an embodiment of the present disclosure.

[0118] When the remote control will not be used for an extended period, a second switching operation can be performed to switch it from a first low-power mode, a second low-power mode, or a normal operating mode to a power-off mode. In power-off mode, the remote control's battery will not supply power to the remote control's processor, motion detection components, light detection components, positioning components, and touch detection components, thereby minimizing power consumption. Specifically, the second switching operation can be performed by executing actions on the remote control's button set. For example, the second switching operation can be performed by pressing and holding one or more buttons included in the user input components. However, those skilled in the art will understand that the second switching operation can be performed by operating other user input components.

[0119] When a user wishes to use the remote control and the remote control is in power-off mode, the user can perform a first switching operation to switch the remote control from a first low-power mode or power-off mode to a normal operating mode. Specifically, the first switching operation can be performed by executing an action on another set of buttons on the remote control. At least one button in the button set used to perform the first switching operation can be different from the button in the button set used to perform the second switching operation, thereby facilitating user differentiation. According to one embodiment of this disclosure, the buttons used for the first switching operation or the second switching operation can be used for operations other than the first switching operation in normal operating mode. That is, in normal operating mode, the buttons used for the first switching operation and the second switching operation can be used for other functions, such as, but not limited to, volume control, communication connection, etc. In this way, buttons can be saved, thereby reducing costs. According to one embodiment of this disclosure, the first switching operation for switching the remote control from a first low-power mode to a normal operating mode can be different from the first switching operation for switching the remote control from a power-off mode to a normal operating mode; for example, the button sets used to perform the above two first switching operations can be different.

[0120] The process of switching from the power-off mode to the normal operation mode is described with reference to circuit 700 shown in FIG7. In the power-off state, when button 701 is not pressed, the enable signal EN_VCC can be low. In response to receiving the low-level enable signal EN_VCC, the power chip 705 may not convert the battery voltage to the supply voltage VCC used in FIG1A and FIG5. In the power-off state, when button 701 is pressed and held, the battery voltage can be used to charge capacitor 704 through resistor 702 and diode 711. After capacitor 704 is fully charged, a high-level enable signal EN_VCC can be formed on resistor 703 according to the resistance values ​​of resistors 702 and 703. In response to receiving the high-level enable signal EN_VCC, the power chip 705 can convert the battery voltage to the supply voltage VCC to power the relevant components of the remote control (e.g., processor, positioning component, light detection component, motion detection component, and touch detection component, etc.), as well as resistor 709 and transistor 708. After the processor 110 of the remote control receives the supply voltage VCC, the processor 110 can output a power holding signal. Therefore, when the user releases button 701, the power holding voltage can be used to continue to provide a high-level enable signal EN_VCC through resistor 704, diode 710, and resistor 703, thereby continuously supplying power to the remote control to enter normal operation mode.

[0121] In normal operating mode, button 701 can be used for other functions, such as, but not limited to, volume control and communication connection. When button 701 is not pressed, transistor 708 can be turned off, so the second operation signal 1 can be high. When button 701 is pressed, resistors 702, 706, and 707 can form a circuit. The bias voltage formed by resistor 707 can turn on transistor 708. Therefore, the second switching operation signal 1 can be low. The second switching operation signal 1 can be input to processor 110. Through the high and low level changes of the second switching operation signal 1, processor 110 can perform other functions such as volume control and communication connection when the remote control is in normal operating mode.

[0122] Referring to the circuit 800 shown in Figure 8, in normal operation mode, when button 810 is not pressed, circuit 800 outputs a second switching operation signal 2 with a high level to processor 110 through resistors 820 and 830. In normal operation mode, when button 810 is pressed, resistor 830 can be short-circuited, thereby providing processor 110 with a second switching operation signal 2 with a low level. By outputting the second switching operation signal 2 with a high or low level, button 810 can be used for functions other than the first and second switching operations, such as volume control, communication connection, etc.

[0123] According to one embodiment of this disclosure, when both the second switching operation signal 1 and the second switching operation signal 2 are received simultaneously, the processor 110 can perform a second switching operation to switch the remote control from a first low-power mode, a second low-power mode, or a normal operation mode to a power-off mode. Specifically, in response to receiving both the second switching operation signal 1 and the second switching operation signal 2 simultaneously, the processor 110 can output a power holding voltage with a low level. Based on the low-level power holding voltage, the circuit 700 outputs an enable signal EN_VCC with a low level, thereby causing the power chip 705 to stop outputting the supply voltage VCC.

[0124] In other words, the user can perform the first switching operation by pressing and holding button 701, and the second switching operation by pressing both button 701 and button 810. In this way, the user can completely disconnect the power connection of the remote control when it is not used for a long time, thereby further saving energy. Those skilled in the art should understand that the type of user input component operated by the user (e.g., button, toggle, etc.), the number of user input components operated by the user (e.g., one, two, etc.), and the operation method (e.g., long press, press, etc.) during the execution of the first and second switching operations are exemplary, and this disclosure is not limited thereto.
