Description

Touch screen control method, device and mobile terminal

technical field

Embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a method and device for controlling a touch screen, and a mobile terminal.

Background technique

At present, the touch screen has become the standard configuration of mobile terminals such as smartphones. Mobile terminal users can easily realize various controls on the mobile terminal by performing touch operations such as clicking, long pressing, and sliding on the touch screen with fingers.

When a user uses a mobile terminal to make a call, the face, ears or other parts of the head often touch the touch screen, causing misoperation and even termination of the call. In order to avoid false touches during a call, existing mobile terminals are usually equipped with a proximity sensor. When the proximity sensor detects that an object is close to the screen of the mobile terminal during a call, the screen is turned off and the touch operation of the object on the touch screen is shielded. To a certain extent, the probability of the above-mentioned misoperations is reduced.

However, in the existing call anti-false touch solution, limited by the detection angle of the proximity sensor and the influence of environmental light and other factors, the proximity sensor will make a misjudgment, and the screen will light up at this time. When the part touches the screen, it will not shield the touch operation, making the function of preventing false touch invalid. Therefore, the existing call anti-false touch solution is prone to misjudgment, and the accuracy of anti-false touch is not high.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

FIG. 1 is a schematic flowchart of a touch screen control method provided by an embodiment of the present invention. The method can be executed by a touch screen control device, wherein the device can be implemented by software and/or hardware, and can generally be integrated in a mobile terminal. As shown in Figure 1, the method includes:

Step 101. Acquire touch data when a touch operation on the touch screen is detected when the mobile terminal is in a call state.

Exemplarily, the mobile terminal in this embodiment may specifically be a terminal device such as a smart phone, a tablet computer, and a smart watch.

In this embodiment, the mobile terminal being in a call state specifically refers to that the mobile terminal is not in the earphone call mode, nor in the hands-free call mode, but is in a normal call mode, and needs to put the mobile terminal to the ear to make a call. At this time, the touch screen is generally in a display state, and the touch sensing function of the touch screen is turned on, so that it can detect whether the touch screen is touched.

When the mobile terminal is in a call state and detects a touch operation on the touch screen, the touch data is acquired. Wherein, the touch data may contain different data due to different types of touch screens. Taking the capacitive touch screen as an example, the touch data can include the capacitance value detected by the touch screen at each position of the screen (or the parameter value corresponding to the capacitance value converted by the touch screen), and can also include specific touch position data, statistically The generated touch point distribution data and touch area data and so on. Specifically, the touch data can be collected by a touch chip (Integrated Circuit, IC).

Step 102, acquiring a preset head touch parameter model.

Exemplarily, the preset head touch parameter model may include the touch parameter data that can be measured by the touch screen when the face, ears and other parts contained in the head touch the touch screen when a person uses a mobile terminal to make a call, Specifically, it may include the capacitance value detected by the touch screen at each position of the screen (or the parameter value corresponding to the capacitance value converted by the touch screen), and may also include specific touch position data, touch point distribution rule data generated after statistics, and Touch area data and more.

Exemplarily, there may be many ways of setting the preset head touch parameter model. For example, the touch data of most users when their heads are in contact with the mobile terminal can be obtained through surveys or simulations, and then the preset head touch parameter model can be set; The touch data is collected for the user of the mobile terminal, and the touch data when the user's head is in contact with the mobile terminal is obtained when the user is using the mobile terminal to make a call, and then a preset head touch parameter model is set. Preferably, the preset head touch parameter model includes: a data model established in advance according to the touch screen touch parameter data corresponding to the current user's call habits when the user's head is in contact with the touch screen.

Step 103, matching the touch data with the preset head touch parameter model, and controlling whether the touch screen responds to the touch operation according to the matching result.

Exemplarily, after matching the touch data with the preset head touch parameter model, if they match (that is, when the touch data matches the preset head touch parameter model), it can be explained that the user's head contact If the touch screen is touched and a false touch occurs, the touch screen can be prohibited from responding to the touch operation; if it does not match, it can indicate that the current touch operation is a normal touch operation of the user, and the touch screen can be controlled to respond to the touch operation. Further, when the touch data matches the preset head touch parameter model, the user can also be prompted for a false touch, such as controlling the mobile terminal to emit a prompt sound or controlling the mobile terminal to generate vibration.

The touch screen control method provided by the embodiment of the present invention matches the acquired touch data with the preset head touch parameter model when the mobile terminal is in a call state and detects a touch operation on the touch screen, and controls the touch screen according to the matching result. Whether the touch screen responds to touch operations. By adopting the above technical solution, using the preset head touch parameter model to identify whether the touch operation during the call is caused by the user's head accidental touch, so that the anti-mis-touch recognition is more targeted, and the anti-mis-touch of the mobile terminal is improved. recognition accuracy.

On the basis of the foregoing embodiments, acquiring a preset head touch parameter model may further include: acquiring a preset finger touch parameter model. Matching the touch data with the preset head touch parameter model, and controlling whether the touch screen responds to the touch operation according to the matching result may specifically include: matching the touch data with the preset The head touch parameter model and the preset finger touch parameter model are respectively matched, and whether the touch screen responds to the touch operation is controlled according to the matching result. Specifically, the matching degree between the touch data and the two preset models can be compared, and when the matching degree with the preset head touch parameter model is higher than the matching degree with the preset finger touch parameter model, it can be explained that the user's head Touch the touch screen and cause a false touch. At this time, the touch screen can be prohibited from responding to the touch operation; when the matching degree with the preset head touch parameter model is lower than or equal to the matching degree with the preset finger touch parameter model, It can be explained that the current touch operation is a normal touch operation of the user, and then the touch screen can be controlled to respond to the touch operation. The specific setting method and principle of the preset finger touch parameter model may be similar to that of the preset head touch parameter model, which may refer to the relevant description above, and will not be repeated here.

Fig. 2 is a schematic flow chart of another touch screen control method provided by the embodiment of the present invention. This embodiment is optimized on the basis of the above embodiment. In this embodiment, the step "detecting the For the touch operation of the touch screen, "get touch data" is optimized to: obtain the detection result of the proximity sensor when the mobile terminal is in the call state; when the touch screen is controlled to be in the bright screen state according to the detection result, detect the touch state of the touch screen; Get the touch data when the touch operation is performed on the touch screen.

Correspondingly, the method of this embodiment includes the following steps:

Step 201. Obtain a detection result of a proximity sensor when the mobile terminal is in a call state.

Exemplarily, an existing mobile terminal is usually configured with a light sensor that packages a proximity sensor and an ambient light sensor together. Therefore, the proximity sensor in this embodiment may also be understood as a light sensor. The most common proximity sensors configured in mobile terminals include infrared proximity sensors. The infrared proximity sensor emits infrared rays outward, and then judges the distance between the object and the sensor by measuring the intensity of the infrared rays reflected back by the object. The stronger the intensity of the received infrared light, the smaller the distance between it and the object. The infrared proximity sensor converts the measured infrared intensity into a measurement value that is directly proportional to it. The larger the measurement value, the smaller the distance between it and the object. In order for the infrared proximity sensor to detect the approaching or moving away of an object, the approaching threshold and the awaying threshold are generally preset. When the measured value is greater than the close threshold value, it can be judged as the close state; when the measured value is less than the far threshold value, it can be judged as the far away state.

After entering the call function, the light sensor's proximity call anti-mistouch function can be automatically triggered. If the detection result of the proximity sensor in the light sensor is close, it can indicate that the mobile terminal may be near the user's head. At this time, the screen can be turned off , and shield the touch-sensing function of the touch screen; if the detection result is far away, it means that the mobile terminal may not be near the user's head, and the user is likely to end the call, dial the extension number or view information on the screen. to light up the screen.

Step 202 : When the touch screen is controlled to be in the bright screen state according to the detection result, the touch state of the touch screen is detected.

Exemplarily, when the touch screen is controlled to be in the bright screen state according to the detection result, it means that the mobile terminal may not be near the user's head. If a problem occurs, it may also be interfered by strong light from the external environment. Therefore, the proximity sensor may misjudgment. In this way, when the user answers the phone with his ear, the screen will light up, which may easily cause false touches. Therefore, in this embodiment, in order to prevent accidental touches, when the touch screen is controlled to be in the bright screen state according to the detection result, the touch state of the touch screen is detected.

Step 203, when a touch operation on the touch screen is detected, touch data is acquired.

Step 204, acquiring a preset head touch parameter model.

Step 205, matching the touch data with the preset head touch parameter model.

Step 206 , judging whether the matching result is a match, if yes, execute step 207 ; otherwise, execute step 208 .

Step 207, prohibiting the touch screen from responding to the touch operation.

Preferably, while performing this step, the screen can also be turned off to save power.

Step 208, controlling the touch screen to respond to the touch operation.

The touch screen control method provided by the embodiment of the present invention combines the proximity sensor judgment method and the preset head touch parameter model judgment method, and can more accurately judge the specific usage status of the user when using the mobile terminal to make a call. When a call is made near the head, the touch screen is prohibited from responding to the touch operation, and when the call is away from the head, the touch screen is allowed to respond to the touch operation, which makes up for the lack of misjudgment that is prone to misjudgment when only the proximity sensor is used for judgment in the existing solution , control the operation of the touch screen more reasonably, and save the system power consumption of the mobile terminal on the basis of the above embodiments.

The internal touch parameter model is updated.

Correspondingly, the method of this embodiment includes the following steps:

Step 301. Obtain a detection result of a proximity sensor when the mobile terminal is in a call state.

Exemplarily, the identity of the current user may be obtained when the mobile terminal is started or unlocked, so that the preset head touch parameter model corresponding to the current user may be obtained when the preset head touch parameter model is subsequently obtained. Specifically, the identity of the current user may be acquired through fingerprint identification or other means.

Step 302 , judging whether it is necessary to control the touch screen to be in a bright screen state according to the detection result, if yes, execute step 303 ; otherwise, execute step 309 .

Step 303 , controlling the touch screen to be in a bright screen state, and detecting the touch state of the touch screen.

Step 304, when a touch operation on the touch screen is detected, touch data is acquired.

Step 306 , judging whether the matching result is a match, if yes, execute step 307 ; otherwise, execute step 308 .

Step 307 , prohibiting the touch screen from responding to the touch operation, and returning to step 301 .

Step 308 , control the touch screen to respond to the touch operation, and return to step 301 .

Step 309 , controlling the touch screen to be in a screen-off state, and detecting the touch state of the touch screen.

Step 310, collect touch data when it is detected that the touch screen is touched.

Step 311 , acquire a preset head touch parameter model, and update the preset head touch parameter model according to the collected touch data, and return to step 301 .

In the touch screen control method provided by the embodiment of the present invention, the preset head touch parameter model includes a pre-established data model based on the touch screen touch parameter data when the user's head is in contact with the touch screen corresponding to the current user's call habit, It can be more targeted to judge whether the mobile terminal is near the user's head according to the current user's calling habits, so as to better prevent the occurrence of accidental touches. In addition, the preset head touch parameter model in this embodiment has a self-learning function, that is, during each call of the user, it continuously obtains capacitance parameter values in different areas within the entire touch screen range to enrich its own database. Increase the accuracy of recognition.

Step 401, enter the call function.

The call function in this embodiment is a non-earphone and non-hands-free mode.

Step 402, triggering the anti-mistouch function of the light sensor for proximity calls.

Step 403: Detect whether the screen is turned on during the call, if yes, execute step 404; otherwise, repeatedly execute step 403.

Step 404 , detect whether a touch operation is generated, if yes, execute step 405 ; otherwise, repeatedly execute step 404 .

Step 405 , compare the touch data corresponding to the touch operation with the face model database, and judge whether it conforms to the face model, if so, go to step 406 ; otherwise, go to step 407 .

Wherein, the face model database includes a preset head touch parameter model, and if the touch data matches the preset head touch parameter model, it conforms to the face model.

Step 406, the mobile terminal does not generate a touch operation response.

Step 407, the mobile terminal generates a corresponding touch operation.
