Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a method for processing a touch operation according to an embodiment of the present invention, where the method may be performed by a touch operation processing apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a mobile terminal. As shown in fig. 1, the method includes:
For example, the mobile terminal in this embodiment may be specifically a device such as a smart phone and a tablet computer, which is integrated with a touch screen.
For example, the first object may include an object that can be recognized by the touch screen, such as a finger, a palm, and a web of a user, and may further include other objects such as a touch pen, a glove, and a cloth of a trousers pocket.
The touch screen adopted by the existing mobile terminal comprises a resistance type touch screen, a capacitance type touch screen, a piezoelectric type touch screen and the like, when a first object touches the touch screen, the touch screen can acquire touch information, and therefore the touch screen is detected to be touched by the first object. Taking a capacitive touch screen as an example, the touch screen can sense the change of capacitance, when a first object touches the touch screen, the touch screen senses the change of capacitance, and then obtains touch information, where the touch information includes x and y coordinates of a touch position, a size (including length and width) of a contact surface, a touch pressure value, and other touch data.
For example, in this step, it may be detected whether the touch screen is touched by the first object through the driving layer, and when the touch screen is detected to be touched, a DOWN event is reported to an upper layer. The upper layer described in the embodiments of the present invention may be a frame layer.
Optionally, when reporting the press event to the upper layer, the method further includes: and starting to report the touch data of the touch screen when the touch screen is touched to the upper layer. When the touch screen is touched by the first object, the driving layer can report the acquired touch data to the frame layer in time, so that the frame layer can quickly execute corresponding operation according to the touch data at a proper time. Before the first object leaves the touch screen, the touch screen can sense the touched object in real time, so the driving layer can also acquire touch data in real time and report the acquired touch data to the frame layer in time.
And 102, reporting false touch information to an upper layer when judging that the current touch area of the first object and the touch screen is larger than a first preset threshold value.
Generally, a user uses a finger to operate on the touch screen, and the contact area between the finger and the touch screen is limited and generally smaller than a certain value. However, when the palm or the skin of a tiger's mouth or other objects touch the touch screen carelessly, the contact area between the palm or the skin of the tiger's mouth or other objects and the touch screen is usually large, so that whether the false touch operation occurs or not can be judged according to the touch area.
For a touch operation, when the driving layer detects that the touch screen is touched, the driving layer reports a press-down event to the frame layer, when the driving layer detects that an object leaves, the driving layer reports a lift-UP (UP) event to the frame layer, and the frame layer responds to the touch operation according to the received press-down event and lift-UP event.
In the prior art, a scheme for preventing false touch exists, when it is detected that an object touches a touch screen, whether the current touch area of the object and the touch screen is larger than a certain threshold value is judged, if so, the false operation is judged, and a pressing event is not reported; if not, judging normal touch, and reporting a pressing event. The inventor finds that the false touch prevention scheme has the following defects: because the parts such as the palm usually have a gradual change process when contacting the touch screen, that is, the touch area is changed from small to large, and the touch area is smaller than the threshold value when the palm is initially contacted, a press-down event can be reported, and a lift-up event can still be reported when the palm leaves the touch screen, so that the frame layer responds to the misoperation.
In the embodiment of the invention, after the press-down event is reported, the driving layer can judge whether the current touch area of the first object and the touch screen is larger than a first preset threshold value in real time, if so, the driving layer can indicate that the mistaken touch occurs, and report the mistaken touch information to the frame layer. The contact area between the finger and the screen during normal touch can be determined by means of investigation or sampling and the like, and then a first preset threshold value is set; the first preset threshold may also be set according to a user's touch habits. The embodiment of the present invention does not limit the specific setting manner and the specific value of the first preset threshold. The false touch information may be embodied in the form of a flag bit, for example, when a false touch occurs, the set flag bit has a value of 1, and when a false touch does not occur, the set flag bit has a value of 0.
Preferably, when reporting the false touch information to the upper layer, the method further includes: and stopping reporting the touch data of the touch screen when the touch screen is touched to the upper layer. The method has the advantages that when the current touch area of the first object and the touch screen is judged to be larger than the first preset threshold value, the mistaken touch is determined to occur, the reporting of touch data is stopped, the frame layer can be prevented from responding to misoperation such as long press or sliding caused by the mistaken touch, and the more comprehensive mistaken touch preventing effect is achieved. In addition, the power consumption loss caused by data reporting can be reduced by stopping reporting the touch data.
And 103, when the first object is detected to leave the touch screen, reporting a lifting event to an upper layer.
For example, when the driving layer detects that the first object leaves the touch screen, it indicates that this false touch operation is finished, and may report a lift-up event to the frame layer, so that the frame layer performs corresponding false touch prevention processing on the false touch operation corresponding to this press-down event.
And step 104, performing corresponding false touch prevention processing on the touch operation corresponding to the pressing event through the upper layer according to the false touch information and the lifting event.
Illustratively, when the frame layer receives the false touch information, it is known that the touch event at the beginning of the touch and the subsequent lift event are events that may cause the false operation of the touch screen, and then the frame layer may adopt a corresponding strategy to perform the false touch prevention processing on the false operation, so as to avoid the false operation of objects such as a palm on the touch screen.
For example, since different touch positions correspond to different operation objects on the screen, the operation objects may be application icons, buttons, desktop and website links, and the like. Different operation pairs may have different response mechanisms to the touch operation, some operation objects may respond to the touch operation after the frame layer receives the lift-off event, and some operation objects may respond to the touch operation before the frame layer receives the lift-off event, so that targeted anti-false touch processing is required.
Optionally, the step may include: judging whether touch operation corresponding to the pressing event is executed or not through the upper layer; if yes, recovering to the state before the touch operation is executed; and if not, shielding the touch operation. For example, the restoration to the state before the touch operation is performed may be understood as eliminating the influence of the touch operation on the mobile terminal, for example, as a result of performing the touch operation, the first button is triggered, and an operation corresponding to the triggered event of the first button is performed, such as switching from the first interface to the second interface, the restoration to the state before the touch operation is performed is switching from the second interface back to the first interface, as if the first button is not triggered. For example, masking the touch operation may be understood as preventing the touch operation from being performed, i.e. the touch operation that is about to be triggered by the lift-off event is not performed although the lift-off event is received.
According to the touch operation processing method provided by the embodiment of the invention, when the bottom layer of the mobile terminal detects that the touch screen is touched by a first object, a pressing event is reported to the upper layer, when the current touch area between the first object and the touch screen is judged to be larger than a first preset threshold value, false touch information is reported to the upper layer, when the first object is detected to leave the touch screen, a lifting event is reported to the upper layer, and finally, corresponding false touch prevention processing is carried out on the touch operation corresponding to the pressing event through the upper layer according to the false touch information and the lifting event. By adopting the technical scheme, the error touch operation of parts except fingers or other objects caused by large-area touch of the screen can be effectively avoided.
Optionally, on the basis of the above technical solution, when it is detected that the touch screen is touched by the first object, reporting a press event to an upper layer includes: when the touch screen is detected to be touched by a first object, if the current touch area between the first object and the touch screen is judged to be smaller than a second preset threshold value, reporting a pressing event to an upper layer. The setting mode of the second preset threshold may be similar to that of the first preset threshold, and the specific numerical values may be the same or different. The advantage of this optimization is that if the touch area of the first object just contacting the touch screen is smaller than the second preset threshold, it indicates that normal touch is possible, so the press event is reported to the upper layer. If the current touch area of the first object and the touch screen is judged to be larger than or equal to the second preset threshold value, which can be indicated as false touch, the pressing event cannot be reported to the upper layer, the false touch prevention work is completed from the moment of the first false touch, and the system resources are saved.
Fig. 2 is a schematic flow chart of another touch operation processing method according to an embodiment of the present invention, where the method includes the following steps:
And step 203, reporting the false touch information to the framework layer.
And step 204, reporting a lifting event to the frame layer when the first object is detected to leave the touch screen.
For example, many different applications may be loaded in the mobile terminal, the starting mechanisms of the applications may be different, some applications may be started when a press event is received, and some applications may be started when a lift event is received, so that the targeted anti-false-touch processing may be performed according to different starting mechanisms of different applications.
For example, whether the touch operation corresponding to the pressing event is an operation for starting the application program may be determined according to whether the coordinate or the area corresponding to the touch area includes the icon of the application program.
For example, the process corresponding to the started application program may be closed, that is, the process corresponding to the started application program is killed, specifically, the framework layer may first obtain the process name of the process corresponding to the application program to be started, and kill the corresponding process according to the process name. It can be understood that, when the time of reporting the false touch information is close enough to the time of reporting the press event, although the application program is started by receiving the press event, a certain time is required from the start to the display of the application interface (for example, the interface of the application program usually needs a certain drawing time, and is sent to the display screen for display after the drawing is completed), if the process of the application program is closed before the display of the application interface, the user does not perceive that the application program is already started, and the interference of the false touch on the user can be effectively eliminated. In addition, if the application interface of the application program is displayed, after the step is executed, the application program which the user does not want to start can be automatically closed, manual closing operation of the user is reduced, and a good false touch prevention effect is achieved.
And step 208, preventing the application program to be started from being started.
For example, although a lift-off event is received, the operation of starting the application program that is about to be triggered by the lift-off event is not performed.
And 209, performing corresponding false touch prevention processing on other types of touch operations corresponding to the press-down event through the frame layer according to the false touch information and the lift-up event.
By adopting the technical scheme, when the user wants to start a certain application program through the error touch operation, the embodiment of the invention can carry out targeted error touch prevention processing according to the starting type of the application program, thereby avoiding the error starting of the application program due to the error touch.
Fig. 3 is a schematic flowchart of a processing method of another touch operation according to an embodiment of the present invention, where the method includes the following steps:
For example, this step may further include setting the touch data upload state of the touch position to a suspend state, taking the current object as the current object when it is detected that the touch position is touched by an object after the current object is detected to leave the touch screen, and returning to perform step 302.
For example, the touch data uploading state of the touch position is in a suspended state, that is, the drive layer does not report the touch data of the touch position to the frame layer.
And step 304, reporting the pressing event to the frame layer, starting to report touch data of the touch screen when the touch screen is touched to the frame layer, and executing step 305.
And step 306, reporting the false touch information to the frame layer, and stopping reporting the touch data when the touch screen is touched to the frame layer.
It should be noted that the touch data that is stopped reporting to the frame layer is touch data generated when the current object is in contact with the touch screen in step 305, and uploading of touch data when other positions of the touch screen are touched is not affected by this step.
And 307, reporting a lifting event to the frame layer when the current object is detected to leave the touch screen.
And step 312, performing corresponding false touch prevention processing on other types of touch operations corresponding to the press-down event through the frame layer according to the false touch information and the lift-up event.
By adopting the technical scheme, the embodiment of the invention can comprehensively identify the false touch and timely perform false touch prevention treatment, and particularly can effectively prevent the application program from being started by mistake due to the false touch.
