All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention.

Please refer to FIG. 1, which is a flowchart of a method for controlling operation of an intelligent terminal by pressing force according to a first embodiment of the present invention. The method for controlling the operation of the intelligent terminal by pressing force according to the first embodiment of the present invention includes the following steps:

Step 100: setting a pressure level corresponding to the pressing force through the smart terminal, and setting an operation instruction corresponding to each pressure level;

In step 100, the manner in which the pressure level is set includes:

1. Set the pressure value threshold of the pressing force, and set the corresponding pressure level according to the pressure value threshold; for example, when the pressure value threshold is set to 100 (unit: gram), the pressure level corresponding to the pressing force is When the pressure value threshold is set to 400, the pressure level corresponding to the pressing force is the heavy pressure level; in actual operation, when the pressure value of the pressing force is greater than 100 and less than 400, it is determined that the pressing force corresponds to The pressure level is a light pressure level; when the pressure value of the pressing force is greater than 400, it is determined that the pressure level corresponding to the pressing force is a heavy pressure level.

2. Set the pressure value interval of the pressing force, and set the pressure level according to the pressure value interval; for example, set the pressing force of the pressure value range of 100-200 to the light pressing level, and press the pressure value range of 400-500. The strength is set to the weight level, so that the user can grasp or distinguish the pressing force to accurately perform the corresponding operation. In the embodiment of the present invention, the pressure level includes but is not limited to the light pressure level and the heavy pressure level, and the set number of the pressure level may be set to multiple according to the operation requirement, for example, the first pressure level, the second pressure level, and the third. Level pressure level, etc. Each pressure level corresponds to an operation command, and the user can set a more frequent operation instruction according to the usage habit, so that the operation is faster and more convenient; the operation instruction includes but is not limited to an on/off operation, a solution/lock screen, and an open/close application. Wait.

In step 100, the user can also set different operation commands corresponding to different pressure levels in different screen states according to usage habits. For example, in the lock screen state, the operation command corresponding to the soft pressing level is set to open the browser. The operation command corresponding to the set weight level is to open the music player; in the bright state (unlocked state), the operation command corresponding to the light pressure level is set to return to the main interface, and the operation instruction corresponding to the set weight level is turned on. Camera, etc.

Step 110: When the user touches the fingerprint chip, determine the current screen state of the smart terminal, if the current screen state is the lock screen state, step 120 is performed; if the current screen state is the bright screen state, step 130 is performed;

Step 120: Collecting a fingerprint image through the fingerprint chip, and performing fingerprint matching on the collected fingerprint image, and unlocking the smart terminal through the fingerprint matching result; at the same time, collecting the pressing force of the user touching the fingerprint chip through the fingerprint chip, and calculating the pressure of the pressing force Value, and perform step 140;

Step 130: Collect the pressing force of the user currently touching the fingerprint chip through the fingerprint chip, and calculate the pressure value of the current pressing force;

In the step 120 and the step 130, when the user touches the fingerprint chip with different pressing force, the fingerprint data collected by the fingerprint chip is different. In the embodiment of the invention, the fingerprint data of the fingerprint chip without finger pressing is separately collected by the fingerprint chip. The fingerprint data when the finger is pressed is compared and the fingerprint data when the finger is pressed is compared with the fingerprint data when the finger is pressed, and the pressure value when the user touches the fingerprint chip is calculated.

Converted to digital signal rawdata (raw data); the fingerprint data difference of base-rawdata is recorded as diff (diff represents the difference between the fingerprint data when no finger is pressed and the fingerprint data when there is a finger press), and the diff value will follow The change in the pressing force changes. In the embodiment of the present invention, the functional relationship between the diff and the finger pressing force is analyzed by using the point method, and the function relationship expression is solved by the method of the piecewise polynomial fitting, and the following functional relationship (1) is obtained:

In the functional relationship (1), pres represents the pressure value (unit: gram), diff represents the difference between the fingerprint data when there is no finger press and the fingerprint data when there is a finger press, a1=1.01, a2=0.39, a3= 0.21, a4=0.43, b1=10.36, b2=132.77, b3=225.15, b4=-161.22, D1=202, D2=593, D3=1697, D4=2715. By collecting the fingerprint data of the user touching the fingerprint chip, according to the function relation (1), the pressure value of the pressing force when the user touches the fingerprint chip can be obtained.

In the embodiment of the present invention, in order to avoid erroneous operation, a time threshold may be set by the smart terminal, and the fingerprint chip collects the pressing force of the user touching the fingerprint chip, and obtains the duration of the pressing force, if the pressing force continues If the time reaches the set time threshold, the pressing force is considered to be a valid value; if the pressing force lasts for less than the set time threshold, the pressing force is considered to be an erroneous operation and ignored.

Step 140: Match the pressure level corresponding to the current pressing force according to the pressure value, and obtain an operation instruction corresponding to the pressure level;

Step 150: Execute the operation instruction on the smart terminal;

In step 150, for example, the current screen state is a lock screen state, and the pressure value calculated by the fingerprint chip according to the current pressing force is 150, and the pressure level corresponding to the current pressing force is considered to be a light pressure level, and the light lock state is obtained when the lock screen state is obtained. The operation command corresponding to the pressure level is to open the browser, and the fingerprint chip automatically opens the browser after unlocking the smart terminal, without manual operation after the user unlocks, which simplifies the operation steps of searching and clicking the browser, thereby saving operation time.

For example, if the current screen state is a bright screen state, and the pressure value calculated by the fingerprint chip according to the current pressing force is 500, the pressure level corresponding to the current pressing force is considered to be a heavy pressing level, and the heavy pressing level corresponding to the bright screen state is obtained.
