[0024] Reference will now be made in detail to the presently preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and description to refer to the same or like parts.

[0025] See also Figure 1 , which depicts a schematic diagram of a first electronic device and a second electronic device according to an embodiment of the present invention. In various embodiments, the first electronic device 10 and the second electronic device 11 may be implemented as any smart device and / or computer device. In some embodiments, one of the first electronic device 10 and the second electronic device 11 may be implemented as a host device (e.g., an HMD), and the other of the first electronic device 10 and the second electronic device 11 may be one of reference devices (e.g., a wearable device) connected to the host device.

[0026] For example, the first electronic device 10 may be an HMD for providing visual content (e.g., VR / MR content) corresponding to a reality service (e.g., VR / MR service), and the second electronic device 11 may be a wearable tracker (e.g., a wearable wrist tracker) connected to the HMD. In this case, when the user experiences visual content provided by, for example, an HMD worn on the user's head or interacts with the visual content, the user may wear the second electronic device 11 on a corresponding body part (e.g., a wrist), and the second electronic device 11 may provide motion data corresponding to the movement of the corresponding body part (e.g., a wrist) to the HMD, so that the HMD may adjust the presented visual content accordingly, but the present invention is not limited thereto.

[0027] In some embodiments, the motion data may be detected by a motion detection circuit on the device under consideration (e.g., the first electronic device 10 and / or the second electronic device 11). For example, the motion detection circuit may be an inertia measurement unit (IMU), and the corresponding motion data may be IMU data measured by the IMU, but the present invention is not limited thereto.

[0028] In other embodiments, there may be other reference devices connected to the host device. Figure 1 For example, in an embodiment where the first electronic device 10 is a host device, the first electronic device 10 can be connected to other reference devices in addition to the second electronic device 11, and the other reference devices can be, for example, other wearable trackers (e.g., wearable ankle trackers), but the present invention is not limited thereto.

[0029] exist Figure 1In the embodiment, the storage circuit 102 is one or a combination of a static or mobile random access memory (RAM), a read-only memory (ROM), a flash memory, a hard disk or any other similar device, and records multiple modules and / or program codes that can be executed by the processor 104.

[0030] The processor 104 may be coupled to the memory circuit 102, and the processor 104 may be, for example, a general-purpose processor, a special-purpose processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) circuit, any other type of integrated circuit (IC), a state machine, etc.

[0031] The structure of the second electronic device 11 (and / or other electronic devices mentioned below) may have the same / similar structure as the first electronic device 10 .

[0032] In an embodiment of the present invention, the processor 104 may access the modules and / or program codes stored in the storage circuit 102 to implement the power management method provided in the present invention, which will be further discussed below.

[0033] See also Figure 2 , which depicts a flow chart of a power management method according to an embodiment of the present invention. The method of this embodiment can be Figure 1 The first electronic device 10 in the embodiment is executed and will be used hereinafter Figure 1 Description of the components shown in Figure 2 Details of each step in the.

[0034] In step S210 , the processor 104 obtains a first communication quality between the first electronic device 10 and the second electronic device 11 .

[0035] In some embodiments, the first communication quality may be characterized by at least one of a received signal strength indicator (RSSI) and a data loss rate. In other embodiments, the first communication quality may be a statistical value of RSSI and / or data loss rate in a measurement window, such as an average RSSI and / or an average data loss rate, but the present invention is not limited thereto.

[0036] In one embodiment, a reference device among the first electronic device 10 and the second electronic device 11 may send a signal to a host device among the first electronic device 10 and the second electronic device 11, and the host device may measure the RSSI and / or data loss rate associated with the reference device as the first communication quality considered in step S210.

[0037] For better understanding, the following discussion will assume that the first electronic device 10 and the second electronic device 11 are a host device and a reference device (eg, a wearable device), respectively, but the present invention is not limited thereto.

[0038] In this case, the second electronic device 11 (e.g., a wearable wrist tracker) may send a signal to the first electronic device 10 (e.g., an HMD), and the first electronic device 10 may measure the RSSI and / or data loss rate of the signal sent from the second electronic device 11 as the first communication quality, but the present invention is not limited thereto.

[0039] In one embodiment, the second electronic device 11 may send the above signal by using a first initial transmission power, and the first initial transmission power may be a predetermined transmission power set by a corresponding manufacturer.

[0040] In another embodiment, the processor 104 may determine the first initial transmit power based on the following first embodiment and / or second embodiment.

[0041] In the first embodiment, before step S210 , the processor 104 may further determine a first initial transmission power of the reference device based on a first relative position between the first electronic device 10 and the second electronic device 11 .

[0042] In a first embodiment, the processor 104 may determine where the reference device is placed. In one embodiment, the processor 104 may provide a user interface for the user to select a location to place the reference device. In some embodiments, the reference device may be placed at some specific locations. For example, if the reference device is a wearable device, the wearable device may be worn on a specific body part of the user, but the present invention is not limited thereto.

[0043] In one embodiment, in response to determining that the reference device is placed at a first position, the processor 104 may determine the first initial transmission power based on a first predetermined power corresponding to the first position. In another embodiment, in response to determining that the reference device is placed at a second position, the processor 104 may determine the first initial transmission power based on a second predetermined power corresponding to the second position, wherein a first distance between the first position and the host device is longer than a second distance between the second position and the host device, and the first predetermined power is higher than the second predetermined power.

[0044] In the first embodiment, the second electronic device 11 (i.e., the reference device under consideration) may be a wearable device. In this case, in response to determining that the wearable device is worn on a first body part of a user of the host device, the processor 104 may determine a first initial transmission power based on a first predetermined power corresponding to the first body part. In addition, in response to determining that the wearable device is worn on a second body part of the user of the host device, the processor 104 may determine the first initial transmission power based on a second predetermined power corresponding to the second body part. In the first embodiment, the first distance between the first body part and the host device is longer than the second distance between the second body part and the host device, and the first predetermined power is higher than the second predetermined power.

[0045] From another perspective, in response to determining that the second electronic device 11 (e.g., a wearable device) is worn on a body part far away from the first electronic device 10 (e.g., an HMD), the processor 104 may determine that the first initial transmission power is a higher power (e.g., a first predetermined power). On the other hand, in response to determining that the second electronic device 11 (e.g., a wearable device) is worn on a body part closer to the first electronic device 10 (e.g., an HMD), the processor 104 may determine that the first initial transmission power is a lower power (e.g., a second predetermined power), but the present invention is not limited thereto.

[0046] In a second embodiment, the processor 104 may request the user wearing the wearable device to maintain a predetermined posture within a predetermined time interval. In various embodiments, the predetermined posture may be any posture based on the designer's requirements, such as a natural standing posture (e.g., standing upright with hands down), but the present invention is not limited thereto.

[0047] Subsequently, the processor 104 may determine the received signal quality associated with the wearable device within a predetermined time interval. In one embodiment, the wearable device may use a predetermined transmission power set by the corresponding manufacturer to send some signals, and the processor 104 may measure the average RSSI within the predetermined time interval as the received signal quality, but the present invention is not limited thereto.

[0048] In this case, the processor 104 may determine the first initial transmission power of the wearable device based on the received signal quality, wherein the first initial transmission power is negatively correlated with the received signal quality associated with the wearable device. That is, the higher the received signal quality, the lower the determined first initial transmission power, and vice versa.

[0049] After determining the first initial transmission power, the processor 104 may control the reference device to use the first initial transmission power to send a signal, and the processor 104 may accordingly obtain the first communication quality in step S210 , but the present invention is not limited thereto.

[0050] See also Figure 3 , which illustrates an application scenario according to the second embodiment of the present invention. Figure 3 , it is assumed that the first electronic device 10 is an HMD and the second electronic device 11 is a wearable device on the wrist of the user 399. In an embodiment, the processor 104 may request the user 399 to maintain a predetermined posture 31 within a predetermined time interval T1.

[0051] In this case, the processor 104 may determine the received signal quality (eg, average RSSI) associated with the wearable device within a predetermined time interval T1 and determine a first initial transmission power of the second electronic device 11 (eg, a reference device) accordingly.

[0052] Then, the user 399 may typically interact with the visual content provided by the first electronic device 10 within time interval T2 and time interval T3, and the processor 104 may determine the first communication quality based on the (average) RSSI and / or data loss rate measured within time interval T2 and / or time interval T3, but the present invention is not limited to this.

[0053] In step S220 , the processor 104 obtains first motion data of a reference device among the first electronic device 10 and the second electronic device 11 .

[0054] In an embodiment, the first motion data may be IMU data detected by an IMU on the reference device under consideration, but the present invention is not limited thereto.

[0055] In step S230 , the processor 104 manages a first transmission power of a reference device among the first electronic device 10 and the second electronic device 11 according to the first motion data and the first communication quality of the reference device.

[0056] In a third embodiment, the processor 104 may determine whether the first communication quality is better than a first quality threshold and whether the first change of the first motion data is lower than a first change threshold.

[0057] In an embodiment of the present invention, the first quality threshold may be set high enough to define a quality of high communication quality. In an embodiment where the first communication quality is characterized by RSSI and / or data loss rate, if RSSI and / or data loss rate indicate that the first communication quality is higher than the first quality threshold, then the first communication quality may be determined to be of high quality, but the present invention is not limited thereto.

[0058] In addition, the first change threshold value may be set low enough to define a change with low change. In one embodiment, the first change of the first motion data may be characterized by a standard deviation of the first motion data, but the present invention is not limited thereto. In this case, if the standard deviation of the first motion data indicates that the first change of the first motion data is below the first change threshold value, then it may be determined that the first motion data has a low change.

[0059] In one embodiment, in response to determining that the first communication quality is better than a first quality threshold and the first change of the first motion data is lower than a first change threshold, the processor 104 may reduce the first transmit power of the reference device.

[0060] That is, if the first communication quality is high quality and the first motion data has low variation, it may indicate that the first transmit power of the reference device may not be too high. In this case, the processor 104 may manage the first transmit power of the reference device by reducing the first transmit power, so that the power consumption of the reference device can be reduced.

[0061] In a fourth embodiment, the processor 104 may determine whether the first communication quality is worse than a second quality threshold and whether the first change of the first motion data is higher than a second change threshold, wherein the first quality threshold is better than the second quality threshold and the first change threshold is lower than the second change threshold.

[0062] In an embodiment of the present invention, the second quality threshold may be set to be sufficiently low to define a quality of low communication quality. In an embodiment where the first communication quality is characterized by RSSI and / or data loss rate, if RSSI and / or data loss rate indicate that the first communication quality is below the second quality threshold, then the first communication quality may be determined to have low quality, but the present invention is not limited thereto.

[0063] In addition, the second variation threshold can be set high enough to define a variation with high variation. In an embodiment where the first variation of the first motion data is characterized by a standard deviation of the first motion data, if the standard deviation of the first motion data indicates that the first variation of the first motion data is above the second variation threshold, then the first motion data can be determined to have a high variation.

[0064] In one embodiment, in response to determining that the first communication quality is worse than a second quality threshold and the first change of the first motion data is higher than a second change threshold, the processor 104 may increase the first transmit power of the reference device.

[0065] That is, if the first communication quality is low quality and the first motion data has a high variation, it may indicate that the first transmission power of the reference device should be higher to achieve better communication quality. In this case, the processor 104 may manage the first transmission power of the reference device by increasing the first transmission power, so that the communication quality between the first electronic device 10 and the second electronic device 11 may be improved.

[0066] Based on the third embodiment and the fourth embodiment, if the first communication quality is between the first quality threshold and the second quality threshold, it can be determined that the first communication quality has a medium quality.

[0067] Similarly, in an embodiment where the first variation of the first motion data is characterized by a first standard deviation of the first motion data, if the standard deviation of the first motion data indicates that the first variation of the first motion data is between a first variation threshold and a second variation threshold, then it can be determined that the first motion data has a medium variation.

[0068] In response to determining that the first communication quality is between the first quality threshold and the second quality threshold and the first change in the first motion data is between the first change threshold and the second change threshold, the processor 104 may maintain the first transmit power of the reference device.

[0069] That is, if the first communication quality is medium quality and the first motion data has a medium variation, it may indicate that the power consumption of the reference device and the communication quality between the first electronic device 10 and the second electronic device 11 are appropriate. In this case, the processor 104 may manage the first transmission power of the reference device by maintaining the first transmission power so that the communication quality between the first electronic device 10 and the second electronic device 11 may be maintained.

[0070] In one embodiment, the management of the first transmit power may be organized as shown in Table 1 below.

[0071]

[0072] Table 1

[0073] In a fifth embodiment, in response to determining that the first communication quality is worse than the second quality threshold and the first change of the first motion data is lower than the first change threshold, it indicates that the first communication quality is low quality and the first motion data has a low change. In this case, it may be implied that the communication path between the first electronic device 10 and the second electronic device 11 has been blocked.

[0074] In this case, the processor 104 may increase the first transmission power of the reference device to try to improve the communication quality between the first electronic device 10 and the second electronic device 11 .

[0075] In an embodiment assuming that the reference device is the second electronic device 11, after managing the first transmission power of the reference device, the first electronic device 10 may further receive other signals transmitted by using the managed first transmission power from the reference device, but the present invention is not limited thereto.

[0076] In an embodiment of the present invention, in response to determining that the first transmit power of the reference device has been managed (e.g., reduced / increased / maintained), the processor 104 may obtain the first communication quality and the first motion data again, and manage the first transmit power again accordingly. That is, the processor 104 may repeatedly perform steps S210 to S230, but the present invention is not limited thereto.

[0077] In one embodiment, in response to determining that the first communication quality is not managed to be between the first quality threshold and the second quality threshold after the first transmit power has been continuously increased or decreased a predetermined number of times, the processor 104 may stop managing the first transmit power for at least a predetermined time length, wherein the predetermined number of times and / or the predetermined time length may be determined based on designer requirements.

[0078] That is, if the first communication quality cannot be adjusted to medium quality after the first transmission power has been continuously increased or decreased for a predetermined number of times, it may indicate that better communication quality cannot be achieved by adjusting the first transmission power of the reference device, so the processor 104 may stop managing the first transmission power for at least a predetermined time length. In this case, the power consumption of the first electronic device 10 may be reduced.

[0079] From another perspective, the reason why better communication quality cannot be achieved by adjusting the first transmission power of the reference device may be that the communication path between the first electronic device 10 and the second electronic device 11 has been blocked. Therefore, in response to determining that the first communication quality still cannot be adjusted to medium quality after the first transmission power has been continuously increased or decreased for a predetermined number of times, the processor 104 may provide a prompt message to remind (the user) to move at least one of the first electronic device 10 and the second electronic device 11. In this case, the communication path between the first electronic device 10 and the second electronic device 11 may not be blocked, so that the processor 104 can improve the communication quality by adjusting the first transmission power of the reference device, but the present invention is not limited to this.

[0080] In another embodiment, in response to determining that the first communication quality has been managed to be between the first quality threshold and the second quality threshold, the processor 104 may stop managing the first transmit power for at least a predetermined length of time.

[0081] That is, if the first communication quality has been adjusted to medium quality, the processor 104 may stop managing the first transmission power at least for a predetermined time period. In this case, the power consumption of the first electronic device 10 may be reduced.

[0082] In addition, in some embodiments, the managed first transmission power may be stored for future use. For example, if the first transmission power has been managed to make the first communication quality medium quality during the user's experience of the visual content of a specific application (e.g., a VR application), the first transmission power may be stored in the settings of the specific application. In this case, when the specific program is started again, the processor 104 does not have to perform the above management again, but can directly use the stored first transmission power to control the second electronic device 11, or control other electronic devices with a configuration similar to the second electronic device 11, but the present invention is not limited to this.

[0083] In the embodiment where the reference device is assumed to be the second electronic device 11, the operation performed in the above embodiment can be understood as the first electronic device 10 managing the first transmission power of the second electronic device 11 according to the first motion data and the first communication quality of the second electronic device 11. Since the communication between the first electronic device 10 and the second electronic device 11 is bidirectional, the first electronic device 10 can use a similar strategy to manage its own transmission power (referred to as the reference transmission power). That is, the processor 104 can manage the reference transmission power of the first electronic device 10 according to the first motion data and the first communication quality of the reference device.

[0084] The details of managing the reference transmit power may refer to the above-mentioned mechanism for managing the first transmit power, which will not be described in detail here.

[0085] In other embodiments where other electronic devices are connected to the first electronic device 10 , the processor 104 may use the above strategy to manage the transmission power of the other electronic devices.

[0086] For example, for a third electronic device among other electronic devices, the processor 104 may obtain a second communication quality between the first electronic device 10 and the third electronic device; obtain second motion data of the third electronic device; and manage a second transmission power of the third electronic device based on the second motion data and the second communication quality.

[0087] The details of managing the second transmission power of the third electronic device may refer to the above-mentioned mechanism of managing the first transmission power, which will not be described in detail here.

[0088] In this case, the transmission power of each of the electronic devices connected to the first electronic device 10 can be properly managed so that interference between the electronic devices can be mitigated. Therefore, the communication quality of the first electronic device 10 and each of the electronic devices connected to the first electronic device 10 can be guaranteed.

[0089] See also Figure 4 , which is a schematic diagram showing the RSSI obtained by an electronic device connected to a first electronic device according to an embodiment of the present invention.

[0090] exist Figure 4 In the example, it is assumed that there are four other electronic devices connected to the first electronic device 10, and the associated communication quality determined in step S210 can be obtained by Figure 4 The RSSI 41 to RSSI 44 on the left side are characterized.

[0091] In an embodiment, Figure 4 The vertical axis in corresponds to the change of RSSI, and Figure 4 The horizontal axis in corresponds to the type of corresponding communication quality, where different types of communication quality may be represented by different types of patterns. For example, RSSI 41 represented by a type pattern of backslashes (i.e., “\”) may have a higher average RSSI than RSSI 42 represented by a type pattern of slashes (i.e., “ / ”), and RSSI 42 represented by a type pattern of slashes (i.e., “ / ”) may have a higher average RSSI than RSSI 43 represented by a type pattern of non-uniform dots. In addition, RSSI 43 represented by a type pattern of non-uniform dots may have a higher average RSSI than RSSI 44 represented by a type pattern of uniform dots, but the present invention is not limited thereto.

[0092] After managing the transmission power of each of the four electronic devices based on the above embodiment, Figure 4 The resulting RSSIs 41 to 44 depicted on the right side of may be more consistent (eg, all RSSIs 41 to 44 are characterized by a slash-type pattern (ie, “ / ”)), indicating that interference between the four electronic devices has been mitigated.

[0093] In addition, although the above embodiments are discussed under the assumption that the reference device is the second electronic device 11, the solution provided by the embodiments of the present invention can also be applied to embodiments in which the reference device is the first electronic device 10. That is, the first electronic device 10 (e.g., a wearable device) can manage its own transmission power based on the first communication quality between the first electronic device 10 and the second electronic device 11 (e.g., an HMD) and the first motion data of the first electronic device 10.

[0094] In this case, the first communication quality may be measured by the second electronic device 11, and the first electronic device 10 may obtain the first communication quality measured by the second electronic device 11 by receiving the first communication quality from the second electronic device 11. In addition, the first electronic device 10 may obtain the first motion data by performing associated motion detection using its own motion detection circuit.

[0095] Then, the first electronic device 10 can manage its own first transmission power accordingly, and transmit other signals by using the managed first transmission power. In addition, after managing its own first transmission power, the first electronic device 10 can further transmit other signals to the second electronic device 11 by using the managed first transmission power, but the present invention is not limited thereto.

[0096] Details can be referred to the above embodiments, which will not be repeated herein.

[0097] The present invention further provides a computer-readable storage medium for executing the power management method. The computer-readable storage medium is composed of a plurality of program instructions (e.g., setting program instructions and deployment program instructions) implemented herein. These program instructions can be loaded into the first electronic device 10 and executed by the first electronic device to perform the power management method and the functions of the first electronic device 10 described above.

[0098] In summary, embodiments of the present invention provide a solution for managing the transmission power of at least one of a first electronic device and a second electronic device, such that interference can be mitigated, power consumption can be reduced, and / or communication quality can be improved.

[0099] It will be apparent to those skilled in the art that various modifications and changes may be made to the structure of the present invention without departing from the scope or spirit of the present invention. In view of the foregoing, it is intended that the present invention covers modifications and changes of the present invention, provided that they fall within the scope of the appended claims and their equivalents.
