detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

At present, the touch technology of the mobile terminal is a technology in which two capacitive sensors of mutual capacitance and self capacitance are simultaneously operated in the touch screen. The mutual capacitance is used to implement the normal traditional direct touch touch. The touch function can accurately implement the touch operation, but partially or completely block the content displayed on the touch screen during the execution of the touch operation; In the floating touch function on the top of the touch screen, the touch function can avoid blocking the content displayed on the touch screen (for example, hovering at a certain position can enlarge the display content of the position), but the false touch rate is high.

Therefore, in general, the floating touch function implemented by the self-capacitance belongs to the auxiliary touch function, and the user usually turns off the hovering touch function in order to avoid a high false touch rate. An embodiment of the present application provides a The hovering touch method aims to provide a hovering touch method with a low false touch rate. The hovering touch method provided by the embodiment of the present application performs a hovering touch operation by using more condition detection, at least including a condition that the coverage area of the hovering touch operation is greater than a threshold, and the method is not for avoiding displaying content on the touch screen. The occlusion is to perform a corresponding response operation by a hovering touch operation on the top of the touch screen when the user is inconvenient to use the physical button touch (for example, doing housework).

Please refer to FIG. 1 , which is a schematic structural diagram of a mobile terminal 100 according to an embodiment of the present invention. For example, the mobile terminal 100 can be a smart phone, a tablet computer, an e-book reader, an MP3 (English: Moving Picture Experts Group Audio Layer III, MP3) player, and an MP4 (English: Moving Picture Experts Group Audio Layer IV, Abbreviation: MP4) player and laptop portable computer, etc.

Please refer to FIG. 2A , which is a flowchart of a floating touch method provided by an embodiment of the present invention. In this embodiment, the method is applied to the mobile terminal shown in FIG. 1 as an example. The floating touch method includes:

Step 201: Acquire a hovering touch operation of the user on the top of the touch screen;

The touch screen senses a user's hovering touch operation within a certain range above the touch screen, and the hovering touch operation affects the capacitor array in the horizontal electrode and the vertical electrode in the touch screen, so that the capacitance in the touch screen changes, thereby triggering the touch screen pair. The change in capacitance generated by the hovering touch operation is processed. The touch screen acquires touch coordinates of the hovering touch operation in the horizontal electrode and the vertical electrode of the touch screen according to the change of the capacitance.

A user refers to an object located above a touch screen, which may be a user's finger, a user's palm, a stylus, a conductive object, and the like.

Within a certain range above the touch screen is a range in which the floating touch operation above the touch screen can cause the capacitance to change.

The touch screen sends the touch coordinates, the trigger time, the signal strength, and the capacitance change of the touch point triggered by the hovering touch operation to the processor.

Step 202: Detect whether the hovering touch operation meets the response condition, and the response condition includes at least the coverage area of the hovering touch operation is greater than the first threshold;

After acquiring the hovering touch operation, the touch screen sends the touch coordinates, the trigger time, the signal strength, and the capacitance change of the touch point triggered by the hovering touch operation to the processor.

The processor obtains a coverage area of the hovering touch operation according to the touch coordinates of the acquired touch touch operation in the horizontal electrode and the vertical electrode of the touch screen, and the processor compares the coverage area of the hover touch operation with the first threshold. It is detected whether the coverage area of the hovering touch operation satisfies the response condition.

Optionally, the first threshold is a pre-set area size.

Optionally, when the hovering touch operation generates a change in capacitance in the horizontal electrode and the vertical electrode on only one touch coordinate in the touch screen, the hovering touch operation is only a single touch on the touch screen. In single touch, only one touch point has a change in capacitance.

When the hovering touch operation produces a change in capacitance of the lateral electrodes and the vertical electrodes on the plurality of touch coordinates in the touch screen, the hovering touch operation is a continuous multi-touch operation on the touch screen. In multi-touch, there will be changes in the capacitance of multiple touch points.

Illustratively, as shown in FIG. 2B, the touch point array is arranged on the lateral electrode and the longitudinal electrode of the touch screen, and the lateral electrode is x and the vertical electrode is y. When the floating touch operation triggers the touch point on the touch screen At 21 o'clock, the capacitance of the horizontal electrode x3 and the vertical electrode y3 of the touch point 21 changes, and the touch screen reports the capacitance change of the touch point 21 to the processor in the form of a touch event, and the touch event includes Trigger time, signal strength, corresponding lateral electrode x3 and longitudinal electrode y3. Similarly, when the hovering touch operation triggers the touch point 22 on the touch screen, the capacitances on the horizontal electrode x8 and the vertical electrode y9 corresponding to the touch point 22 also change. The touch screen reports the trigger time, the signal strength, the corresponding lateral electrode x8 and the vertical electrode y9 of the touch point 22 to the processor in the form of a touch event.

Optionally, according to the above principle, the steps of obtaining the coverage area of the hovering touch operation are as follows:

1. The processor acquires touch coordinates of each touch point that generates a capacitance change in the touch screen, and the touch coordinates include a lateral electrode x and a longitudinal electrode y.

2. The processor acquires the smallest lateral electrode xa and the largest lateral electrode xb of the lateral electrodes x of all the touch coordinates according to the touch coordinates of each touch point; and the smallest of the longitudinal electrodes y that acquire all the touch coordinates The longitudinal electrode yc and the largest longitudinal electrode yd.

Optionally, all touch coordinates refer to touch coordinates corresponding to the touched continuous touch points in the touch screen; or all touch coordinates refer to touch points in the largest connected area among the touched touch points in the touch screen. Corresponding touch coordinates.

For example, the horizontal electrodes corresponding to the triggered continuous touch points in the touch screen include: x2, x3, x4, x5, x6, and x7, and the corresponding longitudinal electrodes include: y3, y4, y5, y6, y7, and y8; The smallest lateral electrode of all touch coordinates is x2, and the largest lateral electrode is x7; the smallest longitudinal electrode of all touch coordinates is y3, and the largest longitudinal electrode is y7.

3. The processor acquires a rectangular area formed by the lateral electrode xa, the lateral electrode xb, the longitudinal electrode yc, and the longitudinal electrode yd, and calculates an area of the rectangular area as a coverage area of the floating touch operation.

As shown in FIG. 2C, among all touch points triggered by the touch touch operation on the touch screen, the smallest lateral electrode is x2 and the largest lateral electrode is x12, the smallest longitudinal electrode is y3 and the largest longitudinal electrode is y8; The rectangular region 23 formed by the lateral electrode x2, the lateral electrode x12, the longitudinal electrode y3, and the longitudinal electrode y8 is obtained, and the area of the rectangular region 23 is calculated as the coverage area of the hovering touch operation.

Optionally, the processor calls the detection module in the memory area of the memory to detect whether the floating touch operation meets the response condition, and the response condition includes at least: the coverage area of the floating touch operation is greater than the first threshold.

Step 203, if the hovering touch operation satisfies the response condition, performing a response operation corresponding to the hovering touch operation;

When the processor detects that the hovering touch operation satisfies the response condition, the processor performs a response operation corresponding to the hovering touch operation.

For example, suppose that the response operation corresponding to the hovering touch operation is to read the short message. When the user is washing clothes, the mobile phone reminder receives a short message. At this time, the user's hand cannot read the short message using the direct contact in the mobile phone, and the user can place the palm on the top of the touch screen. After detecting, the user can Read text messages without touching your phone. As shown in Figure 3.

Optionally, when the hovering touch operation satisfies the response condition, the processor calls the execution module in the memory program area in the memory to perform a response operation corresponding to the hovering touch operation.

Step 204: If the hovering touch operation does not satisfy the response condition, the hovering touch operation is not performed. Response action should be taken.

When the hovering touch operation does not satisfy the response condition, although the hovering touch operation generates a corresponding capacitance change on the touch screen, the processor detects that the hovering touch operation does not satisfy the response condition, and therefore, the processor does not execute the The response operation corresponding to the hovering touch operation.

In summary, the hovering touch method provided by the embodiment obtains a hovering touch operation of the user above the touch screen; and detects whether the hovering touch operation satisfies the response condition, and the response condition includes at least the coverage area of the hovering touch operation is greater than a threshold value; when the hovering touch operation satisfies the response condition, performing a response operation corresponding to the hovering touch operation; and solving the problem that in the prior art, the hovering touch technology can identify the user within a certain range of the surface, resulting in false triggering The problem of high rate is achieved; when the floating touch operation above the touch screen satisfies the response condition, the response operation corresponding to the hovering touch operation is performed, and the probability of occurrence of false triggering is reduced.

In the embodiment shown in FIG. 2A, it is detected whether the hovering touch operation satisfies the response condition, wherein the response condition includes that the coverage area of the hovering touch operation is greater than the first threshold. As another possible implementation manner, the response condition may further include The duration of the hovering touch operation is greater than the second threshold.

Please refer to FIG. 4 , which is a flowchart of a hovering touch method according to another embodiment of the present invention. In this embodiment, the method is applied to the mobile terminal shown in FIG. 1 as an example. The floating touch method includes:

Step 401: Receive a setting instruction.

The touch screen receives a setting instruction triggered by the user at the mobile terminal. The touch screen sends the set command to the processor.

Step 402: Generate and store a correspondence between the hovering touch operation and the response operation according to the setting instruction.

The processor, according to the received setting instruction, calls an execution module included in the memory program area, generates a response operation corresponding to the setting instruction, and stores a correspondence between the floating touch operation and the response operation to the storage data area.

The corresponding relationship between the hovering touch operation and the response operation is not necessarily a one-to-one correspondence. For different display interfaces, the same hovering touch operation can correspond to different response operations; when the processor acquires the hovering touch operation According to the corresponding relationship in the storage data area, if there is a corresponding response operation in the hovering touch operation, a response operation corresponding to the hovering touch operation is performed; if there is no response operation corresponding to the hovering touch operation, The processor does nothing.

For example, the response operation of staying for 3 seconds above the touch screen is to read the short message; when the currently displayed interface is the short message receiving interface, the corresponding response operation for staying for 3 seconds above the touch screen is to view the short message content; The response operation corresponding to one track is to answer the call and the like.

Step 403: Acquire a coverage area of a hovering touch operation of the user above the touch screen.

The touch screen senses a user's hovering touch operation within a certain range above the touch screen, and the hovering touch operation affects the capacitor array in the horizontal electrode and the vertical electrode in the touch screen, so that the capacitance in the touch screen changes, thereby triggering the touch screen pair. The hovering touch operation produces a change in capacitance for processing. The touch screen acquires a coverage area corresponding to the touch coordinates of the floating touch operation in the horizontal electrode and the vertical electrode of the touch screen according to the change of the capacitance.

Within a certain range above the touch screen means that the hovering touch operation above the touch screen can produce a range in which the capacitance changes.

For example, the hovering touch operation allows the user to continuously place the palm of the hand within a certain range above the touch screen for a certain period of time. After the touch screen is sensed, the user's palm is obtained according to the change and duration of the capacitance in the lateral electrode and the vertical electrode on the touch screen. Coverage area and duration above the touch screen.

Optionally, the steps for obtaining the coverage area of the hovering touch operation are as follows:

2. The processor obtains the smallest lateral electrode xa and the largest lateral electrode xb of the lateral electrodes x of all the touch coordinates according to the touch coordinates of each touch point; and obtains the smallest vertical direction of the longitudinal electrodes y of all the touch coordinates. Electrode yc and maximum longitudinal electrode yd.

Step 404: Detect whether a coverage area of the hovering touch operation is greater than a first threshold;

The processor compares a coverage area of the floating touch operation on the touch screen with a first threshold, and detects whether a coverage area of the floating touch operation is greater than a first threshold.

Step 405: If the coverage area of the hovering touch operation is greater than the first threshold, obtain a duration of the hovering touch operation of the user above the touch screen;

When the processor detects that the coverage area of the hovering touch operation is greater than the first threshold, the touch screen generates a capacitance change duration of the capacitor array in the lateral electrode and the vertical electrode according to the hovering touch operation, and acquires a floating touch of the user above the touch screen. The duration of the control operation.

If the coverage area of the hovering touch operation is less than the first threshold, then step 403 is entered.

Step 406: Detect whether the duration of the hovering touch operation is greater than a second threshold;

The processor compares the duration of the hovering touch operation over the touch screen with a second threshold to detect whether the duration of the hovering touch operation is greater than a second threshold.

The second threshold is a predetermined duration set in advance.

Step 407, if the duration of the hovering touch operation is greater than the second threshold, determining a response operation according to the hovering touch operation and the currently displayed user interface;

When the processor detects that the duration of the hovering touch operation is greater than the second threshold, the processor calls the operating system in the memory to obtain the currently displayed user interface, and the processor determines the floating touch with the hovering touch operation and the currently displayed user interface. The response operation corresponding to the control operation.

For example, the hovering touch operation is for the user to place the palm of the hand in a certain range above the touch screen. When the operating system obtains that the currently displayed user interface has a phone access, the processor determines the corresponding according to the hovering touch operation and the phone access interface. The response operation is an operation of answering the phone; when the operating system obtains the currently displayed user interface as the short message receiving interface, the processor determines the corresponding response operation as the operation of reading the short message according to the hovering touch operation and the short message receiving interface.

Optionally, if the duration of the hovering touch operation is greater than the second threshold, the response operation is determined according to the duration of the hovering touch operation, and each of the durations corresponds to one response operation.

The different durations of the hovering touch operation correspond to different response operations.

Exemplarily, the correspondence between the duration of the hovering touch operation and the response operation is as follows in Table 1:

悬浮触控操作的持续时间Duration of the hovering touch operation	响应操作Response operation
3秒3 seconds	读取短信Read text message
6秒6 seconds	接听电话answer the phone
9秒9 seconds	查看电话本View phone book

Table I

When the processor detects that the duration of the hovering touch operation is greater than the second threshold, the processor is suspended according to the The duration of the floating touch operation determines the corresponding response operation.

For example, as shown in Table 1, when the user is inconvenient to use the direct contact touch, if the user needs to read the short message, the palm can be placed on the top of the touch screen for 3 seconds, and the processor is removed after the palm is removed. 3 seconds to determine the corresponding response operation "read SMS"; if the user needs to answer the phone, the palm is placed on the top of the touch screen 6 seconds and then removed, the processor will determine the corresponding response operation after 6 seconds of the palm "received" If the user needs to view the phone book, the palm is placed on the top of the touch screen for 9 seconds and then removed. After the palm is removed, the processor will determine the corresponding response operation “View Phonebook” according to 9 seconds.

If the duration of the hovering touch operation is less than the second threshold, step 405 is performed.

Step 408, performing a determined response operation;

After determining the response operation corresponding to the hovering touch operation, the processor calls the execution module stored in the program area in the memory to perform the determined response operation.

For example, the duration of the hovering touch operation is 6 seconds. After the hovering touch operation meets the response condition, the processor determines that the corresponding response operation is answered according to the duration of the hovering touch operation. Telephone, at this time, the processor controls the mobile terminal to answer the call.

In summary, the hovering touch method provided by the embodiment receives a setting command, generates and stores a correspondence between a hovering touch operation and a response operation according to the setting command, and acquires a hovering touch operation of the user on the touch screen; Detecting whether the hovering touch operation satisfies the response condition, and the response condition includes that the coverage area of the hovering touch operation is greater than the first threshold and the duration of the hovering touch operation is greater than the second threshold; when the hovering touch operation satisfies the response condition, according to the hovering touch The control operation and the currently displayed user interface determine the response operation; perform the response operation; and solve the problem in the prior art that the floating touch technology can identify objects within a certain range of the surface, resulting in a high false trigger rate; The response operation corresponding to the hovering touch operation is performed only when the hovering touch operation above the touch screen satisfies the response condition, thereby reducing the probability of occurrence of the false trigger.

It should be noted that, in this embodiment, the sequence between step 404 and step 407 is not specifically limited, that is, whether the coverage area of the hovering touch operation is greater than the first threshold and the duration of the hovering touch operation is detected. The execution order in which the time is greater than the second threshold is not specifically limited. When the coverage area and the duration of the hovering touch operation are simultaneously satisfied, the response operation corresponding to the hovering touch operation can be performed. The order of execution in the embodiment shown in FIG. 4 is for illustrative purposes only and is not limited.

In the embodiment shown in FIG. 4, the response condition includes a coverage area of the hovering touch operation is greater than the first The duration of the threshold and the hovering touch is greater than the second threshold. In another possible implementation, the response condition includes that the coverage area of the hovering touch operation is greater than the first threshold and the moving speed of the hovering touch operation belongs to the speed threshold interval and / or the moving distance of the hovering touch operation is greater than the third threshold. In the embodiment shown in FIG. 4, step 404 to step 407 may be replaced by the following steps 501 to 506, as shown in FIG. 5:

Step 501: Detect whether a coverage area of the hovering touch operation is greater than a first threshold;

Step 502: If the coverage area of the hovering touch operation is greater than the first threshold, obtain a moving speed of the hovering touch operation of the user above the touch screen;

When the processor detects that the coverage area of the hovering touch operation is greater than the first threshold, the touch screen generates a frequency change of the capacitance in the capacitor array in the lateral electrode and the vertical electrode according to the hovering touch operation, and acquires a floating touch of the user above the touch screen. Control the movement speed of the operation.

If the coverage area of the hovering touch operation is less than the first threshold, step 403 is performed;

Step 503, detecting whether the moving speed of the hovering touch operation belongs to a speed threshold interval;

The processor compares the moving speed of the hovering touch operation on the touch screen with the speed threshold interval, and detects whether the moving speed of the hovering touch operation belongs to the speed threshold interval.

For example, the speed threshold interval is: 1 cm/s to 5 cm/s; when the moving speed of the hovering touch operation is detected to be 2 cm/s, the moving speed of the hovering touch operation belongs to the speed threshold interval; when the floating touch is detected When the moving speed of the control operation is 7 cm/s, the moving speed of the floating touch operation does not belong to the speed threshold interval.

Step 504: If the moving speed of the hovering touch operation belongs to the speed threshold interval, obtain the moving distance of the hovering touch operation of the user above the touch screen;

When the processor detects that the moving speed of the hovering touch operation belongs to the speed threshold interval, the touch screen generates a capacitance change range of the capacitor array in the lateral electrode and the vertical electrode according to the hovering touch operation, and acquires a floating touch of the user above the touch screen. Control the movement distance of the operation.

If the moving speed of the hovering touch operation does not belong to the speed threshold interval, step 502 is performed.

Step 505: Detect whether a moving distance of the hovering touch operation is greater than a third threshold;

The processor compares the moving distance of the hovering touch operation over the touch screen with a third threshold to detect whether the moving distance of the hovering touch operation is greater than a third threshold.

Wherein, the third threshold is a preset distance, or a distance calculated according to the speed threshold interval from.

Step 506, if the moving distance of the hovering touch operation is greater than the third threshold, determining a response operation according to the moving track of the hovering touch operation, each of the moving tracks corresponding to a response operation;

The different movement trajectories of the hovering touch operation correspond to different response operations.

Exemplarily, the correspondence between the movement trajectory of the hovering touch operation and the response operation is as shown in Table 2 below:

从右向左的滑动轨迹Right to left sliding track	读取短信Read text message
从上向下的滑动轨迹Sliding track from top to bottom	查看电话本View phone book

Table II

When the processor detects that the moving distance of the hovering touch operation is greater than the third threshold, the processor determines a corresponding response operation according to the moving trajectory of the hovering touch operation.

For example, the movement track of the touch screen obtained by the touch screen is a right-to-left sliding track.
