The method can detect a contact area where the side edge of the screen of the terminal device is in contact with the operator; judging whether the contact area meets a preset equipment falling-off early warning condition or not; if the contact area meets the equipment falling early warning condition, prompting preset early warning information to prevent the terminal equipment from falling off from the operation body.
In another embodiment of the present application, on the basis of the foregoing embodiments of step S101 to step S103, step S102 may include step S1021 to step S1023:
and S1021, calculating the contact area of the contact area.
And S1022, judging whether the contact area is smaller than a preset area threshold value.
Wherein, the area threshold value can be preset in the terminal device. Or when the terminal device is used by the operating body for the first time, the terminal device prompts the operating body to simulate the holding action when the terminal device is about to fall off, then the terminal device detects the contact area of the side edge of the screen and the operating body, calculates the area of the detected contact area, and determines the area value as the area threshold value.

Therefore, the area threshold value acquired in advance is targeted for each operation body. The accuracy of the judgment process can be improved by using the area threshold with pertinence.
In another embodiment of the present application, based on the embodiments of the foregoing step S1021 to step S1023, step S1021 may include step S201 to step S202:

The preset contact area may be an area fixedly set on the screen of the terminal device in advance. Or, the preset contact area may be a contact area in which the terminal device prompts the operator to normally hold the terminal device when the operator uses the terminal device for the first time, and then the terminal device detects a contact area in which the side of the screen contacts the operator, determines the detected contact area as the preset contact area, and records the detected contact area.
S202, if the contact area is located in the preset contact area, calculating the contact area of the contact area.
In the embodiment of the application, whether a contact area is located in a preset contact area is judged firstly, and if the contact area is located in the preset contact area, the contact area of the contact area is calculated. This may improve the effectiveness of the contact area.
In another embodiment of the application, on the basis of the foregoing embodiments from step S201 to step S202, the determining whether the contact area meets a preset device drop-off warning condition may further include step S301 to step S304:
and S301, if the contact area is smaller than the area threshold, detecting a contact area where the side edge of the screen of the terminal device contacts the operating body at preset first time intervals within a preset first time range.
Illustratively, the first time range may be 3 minutes. The first time interval may be set to 20 seconds.
For example, the correspondence between the time when the contact area is acquired and the contact area within 3 minutes may be as shown in table 1.
TABLE 1
For example, the contact area S5 where the side edge of the screen of the terminal device is in contact with the operator is detected at 1 st minute and 40 seconds within 3 minutes.
S302, determining a first reduced rate of change based on the plurality of contact areas detected within the first time range.
Specifically, step S302 may include steps S3021 to S3022:
s3021, a contact area of each of the plurality of contact regions is calculated, respectively.
The data in table 1 are exemplified as an example. The plurality of contact areas calculated from the plurality of contact areas may be as shown in table 2.
TABLE 2
| Timing of acquisition of contact area | Contact area | Area of contact | |
| Second 20 | S1 | s1 | |
| 40 th | S2 | s2 | |
| 1 st point of | | s3 | |
| 1 minute and 20 | S4 | s4 | |
| 1 minute and 40 | S5 | s5 | |
| 2 nd point of | | s6 | |
| 2 minute and 20 | S7 | s7 | |
| 2 minute and 40 seconds | | s8 | |
| Score | |||
| 3 | S9 | s9 |
For example, the contact area S5 is calculated from the contact area S5.
S3022, determining a first rate of change of reduction from the first time range and the calculated plurality of contact areas.
Specifically, the time when the contact region is acquired is used as an abscissa, the corresponding contact area is used as an ordinate, the correspondence between the contact area and the time when the contact region is acquired is determined, a fitting function is obtained, and the slope of the fitting function is determined as a first reduction rate of change.
For example, as shown in fig. 5, the correspondence between the contact area and the time of acquiring the contact area is determined according to the abscissa as the time of acquiring the contact area and the ordinate as the corresponding contact area in table 2, and a fitting function L1 is obtained. The slope of the fitting function L1 is the first decreasing rate of change corresponding to the data in table 2.
For example, if the fitting function is y ═ kx + b, where x denotes the time at which the contact region is obtained and y denotes the contact area, k in the fitting function is the first decreasing rate of change.
And S303, judging whether the first reduction change rate is within a preset reduction change rate value range.
The range of the reduction change rate may be (K1, K2). In the process of daily use of the terminal device by the operation body, the terminal device can record the contact area reduction change rate in the falling process of the terminal device. The reduction change rate value range can be determined according to a plurality of contact area reduction change rates recorded by the terminal device. The terminal device may also record a new contact area reduction change rate, and then update the obtained reduction change rate value range with the new contact area reduction change rate.
Specifically, step S303 may be: and judging whether the first reduction change rate is greater than K1, if so, judging whether the first reduction change rate is less than K2, and if so, determining that the first reduction change rate is within the value range of the reduction change rate.
S304, if the first reduction change rate is within the reduction change rate value range, determining that the contact area meets the equipment falling-off early warning condition.
In another embodiment of the present application, on the basis of the foregoing embodiments from step S201 to step S202, the determining whether the contact area meets a preset device drop-off warning condition may further include step S401 to step S405:
s401, if the contact area is smaller than the area threshold, determining a second time range according to the difference between the area threshold and the contact area.
Specifically, step S401 may include steps S4011 to S4012:
s4011, calculating a difference value between the area threshold value and the contact area to obtain a target area difference value.
For example, if the area threshold is s0Contact area of s1Then the difference Δ s of the target area is s0-s1。
S4012, determining a second time range corresponding to the target area difference in the correspondence between the preset area difference and the time range.
The corresponding relationship between the preset area difference and the time range can be shown in table 3.
TABLE 3
| Difference in area | Time horizon |
| Δs1 | (0,t1) |
| Δs2 | (0,t2) |
| Δs3 | (0,t3) |
| Δs4 | (0,t4) |
For example, if the target area difference is equal to Δ s2, the second time range corresponding to the target area difference Δ s2 is (0, t)2)。
Wherein if Δ s1 is smaller than Δ s2, t is1Less than t2. This is because the smaller the difference between the area threshold and the contact area is, the closer the current state of the terminal device is to the drop-off state is, and therefore, the detection of the contact area is completed in a shorter time frame. Conversely, the larger the difference between the area threshold and the contact area is, the larger the difference between the current state and the falling-off state of the terminal device is, and therefore, the detection of the contact area needs to be completed in a longer time range. Therefore, the flexibility and accuracy of the determination process can be improved.
S402, detecting a contact area of the side edge of the screen of the terminal equipment and the operating body at preset second time intervals in the second time range.
Illustratively, the second time interval may be determined from the second time range. If the second time range is smaller, a smaller second time interval may be determined. For example, if the second time range is 1 minute, the second time interval may be set to 10 seconds. If the second time range is 2 minutes, the second time interval may be set to 15 seconds. If the second time range is 3 minutes, the second time interval may be set to 20 seconds.
For example, the correspondence between the time when the contact region is acquired and the contact region within 1 minute may be as shown in table 4.
