Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic devices, and particularly to a low-power air gesture operation method for an electronic device. Background Art
[0002] With the popularization of electronic devices, such as mobile phones, tablets, watches and other electronic devices gradually integrating into people's lives, the use of electronic devices all operates on a touch display screen. However, in special cases, when wanting to operate the device, due to residues such as water or oil stains on both hands, it is inconvenient to directly operate the touch display screen, resulting in a poor user experience. To solve this problem, many manufacturers have added the function of air gesture operation to electronic devices, improving the user experience.
[0003] The existing air gesture operation functions all use a camera to record gesture actions, cooperate with complex algorithms to identify gestures, and control the electronic device to perform operations corresponding to the gestures, so as to achieve the operation of the electronic device without touching the screen. However, the existing solutions are achieved through the cooperation of a camera and complex algorithm detection. The cost of the camera is relatively high, and the requirement for the algorithm recognition ability is relatively high, which even affects the power consumption of the electronic device and is not conducive to improving the competitiveness of the product. Summary of the Invention
[0004] To solve the problems in the prior art, the present invention provides a low-power air gesture operation method for an electronic device.
[0005] A low-power air gesture operation method for an electronic device according to the present invention includes the following steps:
[0006] S1: Turn on the air gesture switch function, and set gesture parameters and control instructions;
[0007] S2: The distance sensor on the electronic device detects whether it is in an occluded situation;
[0008] S3: If it is occluded, obtain the occlusion time and send the occlusion time to the controller of the electronic device;
[0009] S4: The controller of the electronic device determines whether to execute a preset control instruction according to the occlusion time;
[0010] S5: If the occlusion time corresponds to the gesture parameters, the system of the electronic device performs corresponding air operations;
[0011] S6: The air operation is completed.
[0012] The present invention is further improved. In step S1, the gesture parameters include occlusion time and occlusion distance value.
[0013] The present invention is further improved by further including the following steps between step S1 and step S2:
[0014] A01: Set up application software that requires gesture control;
[0015] A02: Determine whether the current interface is an application software that can be controlled by gestures;
[0016] A03: If yes, the distance sensor performs judgment and recognition; if no, the distance sensor performs recognition without judgment and recognition.
[0017] The present invention is further improved, and the steps for determining the shielding time in step S4 are as follows:
[0018] B01: Determine whether the occlusion time value matches the preset occlusion time;
[0019] B02: When the blocking time is greater than or less than, the controller of the electronic device does not execute the control instruction.
[0020] The present invention is further improved in that the shielding distance value may be gradually increased or gradually decreased.
[0021] The present invention is further improved in that the distance sensor can be an infrared distance sensor or a laser distance sensor.
[0022] The present invention is further improved by setting the occlusion frequency time and the occlusion frequency value in step S1. When the distance sensor in step S2 appears a number of times greater than or equal to the occlusion frequency value within the occlusion frequency time range, it is judged that the current electronic device is unstable, and a prompt is given to place the electronic device still before performing the air gesture operation.
[0023] Compared with the prior art, the beneficial effect of the present invention is that the use of its mechanism can effectively solve the problems of high power consumption and high cost in the existing methods of realizing air-to-air operation. By using this method, the distance sensor provided by the electronic device can be combined with a simple threshold comparison to realize air-to-air gesture control, which reduces the power consumption of the device while effectively controlling the cost of the product, greatly improving the user experience.

The terms "first", "second", etc. in the description and claims of the present invention or the above drawings are used to distinguish different objects and not to describe a specific order.
[0027] Referring to "embodiments" in the present invention means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in the present invention can be combined with other embodiments.
[0028] In order to enable those skilled in the technical field to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings.
[0029] As Figure 1 shown, the low-power air gesture operation method for an electronic device of the present invention is applied to an electronic device with a distance sensor. The electronic device described below is a mobile phone. The operation method is as follows:
[0030] 1. Turn on the air gesture switch function and set gesture parameters and control instructions.
[0031] Before using this function, first turn on this function on the mobile phone. After turning on this function, then set the gesture parameters and control instructions, and the gesture parameters and control instructions are in one-to-one cooperation.
[0032] The gesture parameters include the occlusion time and the occlusion distance value.
[0033] The occlusion distance value can gradually increase or gradually decrease, which is set according to requirements. For example, for the quick slide-down instruction, the condition is that the occlusion distance value decreases significantly in a short time (the hand approaches quickly) and then recovers (the hand leaves), and for the page hover operation instruction, the condition is that the occlusion distance value remains stable at a low rate (the hand moves slowly or is stationary). Both can be operated through this parameter.
[0034] And by jointly judging with the occlusion time and the occlusion distance value, the accuracy is higher. For example, the above actions need to be triggered within a set range.
[0035] Under the condition of increasing hardware costs, the algorithm complexity of implementing the above operations is also relatively low, resulting in cost reduction and power consumption reduction.
[0036] The distance sensor can be an infrared distance sensor or a laser distance sensor.
[0037] Since distance sensors can generally detect obstacles within a specified range, when any obstacle blocks the distance sensor within the specified range, the sensor will identify it as an occluded state at this time.
[0038] When the user makes relevant air gesture operations (such as swiping up, spreading the palm, etc.), it is generally detected by the distance sensor that there is an occlusion. Therefore, functions such as swiping and muting required by the user can be simply implemented through the detection of the distance sensor.
[0039] For example, when the distance sensor is not occluded and detects that the occlusion time is less than the 500ms threshold (it is preset that the user's gesture swipe occludes the sensor for less than 500ms, and this value can be modified), the system determines that the current user has performed an air gesture operation at this time, and the system performs corresponding simulation operations (such as swiping up) to implement a simple air operation function.
[0040] If the detected occlusion time exceeds a certain threshold, no processing is done, which can avoid misjudgment operations when the mobile phone is placed down on the desktop in the pocket.
[0041] For another example, if the occlusion time exceeds 3 seconds, the system automatically mutes (the same principle can be implemented. When the phone is ringing and the user's hand is inconvenient to pick up the phone, just place the hand above the distance sensor for 3 seconds to achieve the air mute operation).
[0042] For the occlusion distance value, in order to use it more efficiently, hierarchical operations can also be implemented.
[0043] For example, multiple distance intervals (such as 10cm, 20cm, 30cm) are set to correspond to different operation levels.
[0044] 20cm - 30cm: Hand hovering triggers the preview mode (such as the music cover unfolds), 10cm - 20cm: Swipe-down gesture triggers the page-turning operation, less than 10cm: Quick approach triggers the confirmation command (such as click).
[0045] For the gesture parameters, a signal strength parameter can also be added to improve the recognition accuracy, and the infrared signal reflection intensity difference of the distance sensor is used to judge the hand movement direction.
[0046] When the hand swipes from left to right, the signal strength of the left sensor decays earlier than that of the right sensor, and the horizontal swipe is judged according to the change of the signal strength.
[0047] 2. The distance sensor on the electronic device detects whether it is in an occluded situation.
[0048] Before detecting with the distance sensor, the following steps are also included:
[0049] (1) Set the application software that requires gesture control.
[0050] (2) Determine whether the current interface is an application software that can be gesture-controlled.
[0051] (3) If so, the distance sensor makes a judgment and identification. If not, the distance sensor makes an identification without making a judgment.
[0052] By identifying the current application software, the occurrence of false triggering can be effectively reduced.
[0053] Before the distance sensor detects, by setting the occlusion frequency time and the occlusion frequency value, when the distance sensor detects, if the number of times is greater than or equal to the occlusion frequency value within the set occlusion frequency time range, it is determined that the current electronic device is unstable, and it is prompted to place the electronic device stationary and then perform an air gesture operation, further reducing the occurrence of false triggering.
[0054] Of course, setting the occlusion frequency time and the occlusion frequency value can also activate the air operation function. For example, when occluded twice within 2 seconds, the function of cutting the next song in the music playing software is performed by air gesture. When occluded three times, the function of cutting the previous song in the music playing software is performed by air gesture.
[0055] 3. If it is occluded, obtain the occlusion time and send the occlusion time to the controller of the electronic device.
[0056] The controller of the electronic device judges the parameter of the occlusion time.
[0057] 4. The controller of the electronic device determines whether to execute a preset control instruction according to the occlusion time;
[0058] The judgment steps of the occlusion time are as follows:
[0059] (1) Judge whether the occlusion time value matches the preset occlusion time;
[0060] (2) When the occlusion time is greater than or less than, the controller of the electronic device does not execute the control instruction.
[0061] By simple judgment, the activation of the corresponding air operation control instruction can be realized.
[0062] 5. If the occlusion time corresponds to the gesture parameter, the system of the electronic device performs the corresponding air operation.
[0063] 6. The air operation is completed.
[0064] In summary, a low-power air gesture operation method for an electronic device provided by the present invention can effectively solve the problems of high power consumption and high cost existing in the existing methods for realizing air operation. By using this method, the distance sensor built in the electronic device can cooperate with a simple threshold comparison to realize air gesture control, reducing the power consumption of the device while effectively controlling the cost of the product and greatly improving the user experience.
[0065] The above specific implementation manners are the preferred implementation manners of the present invention, and do not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
