The priority of the Chinese Patent Application for "Importing Method and Device of Input Interface", the entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the field of electronic device control technologies, and in particular, to a method and device for switching an input interface. Background technique

With the continuous development and improvement of touch display technology, electronic devices using this technology are becoming more and more common, such as touch show mobile phones, touch show e-readers, and the like. The application of touch display technology in electronic devices has improved and improved the functions of electronic devices, so touch screen devices have gradually become the development trend of electronic devices.

The application of touch screen technology in electronic devices is gradually integrated with various functions of electronic devices. For example, the electronic device acquires external operation information of the electronic device through the touch screen, and controls the electronic device according to the acquired operation information. Among them, a more common application is to provide an input interface for inputting information to the user by the touch display instead of the traditional physical keyboard input interface.

The input interface provided by the touch screen mainly includes a virtual keyboard interface and a handwriting input interface. The virtual keyboard interface mainly refers to a virtual keyboard interface including various buttons on the touch screen of the electronic device. The layout manner of each button in the virtual keyboard mostly inherits the layout mode of the traditional physical keyboard, and the user can click the virtual keyboard interface. The corresponding button on the keyboard is used to input information; compared with the virtual keyboard interface, the handwriting input interface allows the user to input information directly by handwriting on the handwriting input interface, thereby reducing the limitation of the virtual keyboard key to the user input.

At present, the touch screen device can generally support the virtual keyboard interface and the handwriting input interface at the same time, so as to improve the applicability of the touch screen device and meet the input habits of different users. In a touch screen device that supports both a virtual keyboard interface and a handwriting input interface, one of the input interfaces is generally set as the default input interface of the touch screen device, that is, when the user needs to input information to the touch display device, the set default input interface is usually displayed first. . If the user wants to use another input interface for information input, the input interface can be switched manually. For example, the user can switch the input interface by means of a shortcut button, that is, define a specific button on the touch screen as a shortcut button for switching. In general, if the virtual keyboard interface is switched to the handwriting input interface, the specific button on the virtual keyboard is usually set as the shortcut button; if the handwriting input interface is switched to the virtual keyboard interface, the touch display is usually located in the handwriting input. A specific button on a region other than the region is set as the shortcut button. The user can switch the input interface of the touch display by clicking on the shortcut button provided on the touch show. This switching method implemented by the shortcut button reduces the user The complexity of the input interface switching, but in practical applications, there will be the following problems:

On the one hand, the above switching method requires the user to memorize the shortcut button provided by the touch screen device for switching the input interface. Especially in the case of ever-increasing types of touch-display devices, the difference between the model or manufacturer of the touch-display device often results in different shortcut buttons provided by different touch-screen devices. If the user forgets the shortcut button for switching or remembers the shortcut button for switching, it may cause the switch to fail;

On the other hand, the touch display device has a limited touch display size, and each key of the virtual keyboard usually occupies a small area, and the position of each button is relatively compact. In this case, when the user clicks the shortcut button, the click is made. There may be deviations between the area and the area of the shortcut button, so that the touch display cannot accurately sense the user's click operation on the shortcut button. Especially in the case where the deviation is large, the user's operation on the shortcut button is likely to be sensed by the touch screen as the user. The operation of other buttons causes the switch to fail.

In summary, the switching of the touch screen input interface is performed according to the method provided by the prior art, and there is a problem that the switching fails due to the user forgetting or remembering the shortcut key or the wrong operation, and the success rate of the switching is low. Summary of the invention

And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Embodiment 1

Embodiment 1 of the present invention provides a method for switching an input interface, and the method can be applied to a touch screen electronic device, such as a touch display mobile phone, a touch display electronic reader, or the like. The method can automatically realize the switching of different input states of the touch display according to the operation mode of the touch display by the user and the preset switching condition, wherein the switching of the different input states of the touch display mainly includes: switching from the handwriting input interface to the virtual keyboard interface And switch from the virtual keyboard interface to the handwriting input interface.

FIG. 1 is a schematic flowchart of a method for switching an input interface according to Embodiment 1 of the present invention. As shown in FIG. 1 , the method for switching the input interface mainly includes the following steps:

Step 101: After detecting that the touch screen is performed, the electronic device acquires a touch event of an operation currently performed by the touch screen. Since the "event" is often composed of various kinds of information, in particular, the electronic device may acquire touch event information for the operation currently performed by the touch screen. In the embodiment of the present invention, "the operation of the touch screen currently being performed" The touch event "can be equivalent to "touch event information for an operation currently performed by the touch screen", which is not further distinguished below.

In step 101, the touch event of the touch screen is used to represent the operation performed by the touch screen, that is, the touch screen senses the outside world.

(usually refers to a finger or a touch pen) operations on the touch screen, for example, external click operations on the touch screen, sliding operations, and the like.

Step 102: Determine an operation performed by the touch screen represented by the currently acquired touch event.

In this step 102, the operation performed by the touch event represented by the touch event mainly includes a click operation and a sliding operation.

Step 103: Control switching of the touch screen input interface according to the determined operation performed by the touch screen and the input interface currently displayed by the touch screen.

At this point, the switching process of the input interface ends.

In the step 103 included in the process corresponding to FIG. 1, the switching operation mode of the touch screen input interface is also different according to the difference in the operation performed by the touch screen represented by the acquired touch event and the input interface currently displayed on the touch screen, for example, in the step. When the touch screen represented by the touch event is performed, the operation performed by the touch screen is a click operation, and the subsequent touch event of the touch screen is continued to be used, and the subsequent touch event is used to represent the subsequent operation of the touch screen after the click operation is performed, until the operation is performed. After the subsequent touch event is characterized by the subsequent operation of the touch screen being performed to satisfy the corresponding switching condition, the control input interface switches. Hereinafter, each control mode will be described with reference to specific embodiments.

Specific embodiment 1

DETAILED DESCRIPTION The embodiments described above a given operation is determined in step ₁₀₂ is executed show touch slide operation when the specific control mode in step 103. According to the first embodiment, if the touch screen is subjected to the sliding operation, the subsequent control manner needs to be further determined according to the input interface currently displayed on the touch screen, specifically:

If the input interface currently displayed by the touch display is a handwriting input interface, the process is processed according to the prior art, that is, the operation is determined as the input information of the outside touch screen, and the switching process of the input interface is not performed;

If the input interface currently displayed on the touch screen is a virtual keyboard interface, a switching process of the input interface is required, that is, the touch display is switched from the virtual keyboard interface to the handwriting input interface, wherein the touch display is switched from the virtual keyboard interface to the handwriting input interface. For the existing functions of the touch display device, it will not be described here.

According to the first embodiment, when the touch screen displays the virtual keyboard interface, if it is detected that the outside world performs a sliding operation on the touch screen, the touch screen is switched from the virtual keyboard interface to the handwriting input interface.

Further, the first embodiment further provides a preferred embodiment, by setting the number of times that the touch screen is continuously detected to be performed, and continuously obtaining the sliding operation indicating that the touch screen is performed. When the number of touch events reaches the set threshold, the touch screen is switched from the virtual keyboard interface to the handwriting input interface, otherwise it does not switch. With the preferred embodiment, the switching of the touch screen input interface is performed when the sliding operation is performed a plurality of times when the touch display is detected, and unnecessary switching due to the user's erroneous operation is avoided.

Specific embodiment 2

The second embodiment of the present invention provides the control mode of the above step 103 when the operation performed by the above-mentioned step ₁₀ 2 is a click operation and the input interface currently displayed on the touch screen is a virtual keyboard interface.

According to the control needs, it is necessary to preset a switching condition that should be satisfied when the touch display is switched from the virtual keyboard interface to the handwriting input interface (for convenience of description, which is hereinafter referred to as a first switching condition), the first switching condition is specifically: the touch screen is executed The operation is a sliding operation, that is, when the acquired touch event characterizes that the touch screen is subjected to the sliding operation, it is determined that the first switching condition is satisfied.

2 is a schematic flow chart of controlling touch screen switching when the operation performed by the touch screen determined in step 102 is a click operation and the input interface currently displayed by the touch screen is a virtual keyboard interface, as shown in FIG. As shown in Figure 2, it mainly includes the following steps:

Step 201: Acquire the touch event of the touch exhibition again.

In this step 201, the operation of the touch screen characterized by the touch event of the touch screen acquired again is performed, and the operation performed after the operation of the touch screen characterized by the touch event last acquired is performed. Moreover, the interval between the time when the touch event is acquired again and the time when the touch event was last acquired should be smaller than the first set threshold, which is used to identify the time when the user inputs a character (or is called character recognition). Time), that is, if the interval between the time when the touch event is acquired again and the time when the touch event was last acquired is less than the first set threshold, it is determined that the user input has not been completed, otherwise, it is determined that the user input information is completed.

Step 202: Determine whether the operation performed by the touch screen represented by the touch event acquired again meets the first switching condition, and if yes, execute step 203, and if no, perform step 204. In this step 202, it is determined whether the operation performed by the touch screen characterized by the touch event acquired again meets the first switching condition, that is, whether the operation performed by the touch screen represented by the touch event acquired again is a sliding operation, and if it is a sliding operation, determining The first switching condition is met, otherwise it is not satisfied. The first switching condition refers to a condition that the touch display needs to be switched from the virtual keyboard interface to the handwriting input interface, and the setting of the condition is as described above, and details are not described herein again.

Step 203: Switch the virtual keyboard interface displayed by the touch display to a handwriting input interface.

In this step 203, the manner in which the touch screen is switched from the virtual keyboard interface to the handwriting input interface is an existing function of the touch screen device, and details are not described herein again.

Step 204: Determine an operation performed by the touch screen represented by the touch event that is acquired again as a click operation, and determine click position information on the touch screen corresponding to the click operation according to the touch event, and save, and then return to step 201.

At this point, the process of controlling the touch show switching ends.

In step 204 of the corresponding process of FIG. 2, the main purpose of saving the click location information is to assist in determining the information of the user's handwriting input, and after switching the virtual keyboard interface of the touch display display to the handwriting input interface according to the saved click location information, The process of determining the information input to the touch screen is further performed. As shown in FIG. 3, the process of determining the information input to the touch screen mainly includes the following steps:

Step 301: Acquire a touch event for characterizing that the handwriting input interface of the touch screen display is performed.

In the step 301, the acquired touch event indicates a touch event corresponding to the operation of the user inputting information through the handwriting input interface after the touch screen is switched from the virtual keyboard interface to the handwriting input interface.

Step 302: Determine whether the user inputs the input, and if yes, go to step 303, otherwise return to step 301.

In step 302, it is determined whether the user has finished inputting, that is, whether the touch event is acquired again within the set time length after acquiring the touch event, and if not, determining that the user input is completed, wherein the setting is The length of time identifies the time (or referred to as the character recognition time) at which the user has entered a character, which may be equal to the first set threshold described above.

Step 303: Determine, according to the operation of the handwriting input interface displayed by the touch screen represented by the acquired touch event, and the saved click position information, determine the information input to the touch exhibition.

At this point, the process of determining the information input to the touch show ends.

In step 301 of the corresponding process of FIG. 3, the interval between the time when the touch event is acquired by the handwriting input interface for the first time and the time when the last time the sliding event for characterizing the touch screen is performed is less than the second set threshold. And in addition to the touch event acquired through the handwriting input interface for the first time, the interval between the time when the touch event is acquired through the handwriting input interface and the time when the touch event is acquired through the handwriting input interface is less than The second set threshold. Here, the second set threshold is substantially the same as the first set threshold, that is, a time for identifying that the user inputs a character (or a character recognition time), and the second set threshold may be the first Set the threshold to be the same, or you can match different values according to the requirements of different input interfaces. According to the flow corresponding to FIG. 3, by saving the click position information of the point at which the touch screen is switched from the virtual keyboard interface to the point before the handwriting input interface, the touch display can be used to determine the accuracy of the information input by the user, in order to better understand the determination. The process of inputting information to the touch exhibition, a specific example is given below:

When the user inputs the information "河", the stroke input first is a point, and the stroke can be touched by the touch screen as a click operation, because the virtual keyboard interface is switched to the handwriting input interface after detecting the sliding operation, at this time, if the click is not saved The click position information of the operation, the information input by the user sensed through the handwriting input interface is "may", that is, the "';" input by the user before the input interface is switched to the handwriting input interface cannot be perceived by the handwriting input interface, and may appear The problem that the information touched by the touch screen does not match the information actually entered by the user. Therefore, in order to avoid the problem that the information sensed after the touch-over switching does not match the information actually input by the user, it is necessary to pre-save the click position information corresponding to the click operation before the switching, that is, record the position information of the point included in the input information, After the touch display is switched from the virtual keyboard interface to the handwriting input interface, the user can continue the handwriting input, so that after the user inputs through the handwriting input interface, the "';" information recorded before the switching can be obtained and the "can" obtained after the switching. The information is combined as the basis for the text generation in the text selection box to determine the information entered by the user as "river". When the user selects a text, the system automatically clears the recorded click position information.

According to the above processing manner provided by the second embodiment of the present application, when the user inputs using the virtual keyboard interface, if the user wants to input using the handwriting input interface, the user does not need to touch the shortcut button or enter the input interface setting window to change the input interface to the handwriting input interface. Instead, the handwriting input is directly performed on the touch screen, and the system automatically recognizes that the user is performing handwriting input according to the above method, thereby automatically switching to the handwriting input interface.

In the practical application, the technical solution provided by the second embodiment of the present invention identifies a specific method for the user to perform handwriting input: 3⁄4:

When the user operates on the touch screen, the touch screen device senses the corresponding touch event. For example, click (down->up), slide (down->move->up), long press, etc. In general, the stroke input is a sliding operation, so it can be determined whether there is a stroke input by waiting for a touch event for characterizing the sliding operation. If there is a sliding operation, it is determined that the user is performing handwriting input, and automatically cancels the virtual keyboard interface. , Open the handwriting input interface. After the touch screen device senses the user's operation, it automatically determines whether the user's operation is a click, a slide, or a long press. If it is an operation, the touch screen device will respond in the defined callback function, that is, once the sliding operation occurs, the corresponding callback function will be triggered and the operation will be performed in the function (ie, the virtual keyboard interface is switched to the handwriting input). Interface), the specific callback function is as follows:

Private void onMoveEvent(){

switchTomanuscript(); This callback function means to switch the virtual keyboard interface to the handwriting input interface. During the opening of the handwriting input interface, the user can continue to perform handwriting input without interrupting the operation. When the user stops the handwriting operation to reach the set text recognition In the case of (for example, 0.5 seconds), the user is determined to complete the input of the text, and a text selection box pops up for the user to select the text. The foregoing Embodiment 1 and Embodiment 2 both implement control of switching the touch screen from the virtual keyboard interface to the handwriting input interface. The second embodiment is related to the foregoing specific implementation manner, because the click operation is saved before the switching. The corresponding click position information can accurately display the Chinese characters whose starting stroke is a point.

FIG. 4 is a schematic diagram of a process for inputting a Chinese character input according to the switching method of the input interface provided in the second embodiment. As shown in FIG. 4, the process of implementing the Chinese character input mainly includes the following steps:

Step 401: After detecting that the touch screen is performed, the electronic device acquires a touch event of an operation currently performed by the touch screen;

Step 402: Determine whether the touch operation represented by the touch event is performed as a click operation, and if yes, execute step 403, if no, perform step 404;

Step 403, according to the acquired touch event, record the click position information of the touch exhibition corresponding to the click operation, and return to step 401;

Step 404: Determine whether the acquired touch event representation of the touch screen is performed as a sliding operation, and if yes, perform step 405, if no, return to step 401;

Step 405: Switch the touch exhibition from the virtual keyboard interface to the handwriting input interface.

Step 406: After determining that the user stops inputting, obtain the saved click location information, and display the information input by the user for the user to select.

At this point, the process of implementing the Chinese character input ends.

Embodiment 3

The third embodiment shows the control mode of the above step 103 when the operation performed by the above-mentioned step 102 is a click operation and the input interface currently displayed by the touch display is a handwriting input interface.

According to the control needs, it is necessary to preset a switching condition that should be satisfied when the touch display is switched from the handwriting input interface to the virtual keyboard interface (for convenience of description, which is hereinafter referred to as a second switching condition), the second switching condition may be: The setting button on the virtual keyboard interface is clicked to set the number of times, that is, when the acquired touch event characterizes that the setting button on the virtual keyboard interface of the touch display pre-display is clicked by the set number of times, it is determined that the second switching condition is satisfied.

FIG. 5 is a schematic flow chart of controlling touch screen switching when the operation performed by the touch screen determined in step 102 is a click operation and the input interface currently displayed on the touch screen is a handwriting input interface, as shown in FIG. As shown in Figure 5, it mainly includes the following steps:

Step 501: Pre-switch the handwriting input interface displayed on the touch screen to a virtual keyboard interface displayed with transparency greater than the set value.

In the step 501, the handwriting input interface of the touch display is pre-switched to a virtual keyboard interface displayed with transparency greater than the set value, that is, the area of the virtual keyboard is pre-displayed on the touch show, and the virtual keyboard interface is displayed in a semi-transparent state. Determining whether to display the virtual keyboard interface completely or to cancel the virtual key displayed in the semi-transparent state according to the input of the subsequent user Disk interface. The greater the transparency, the more transparent the pre-displayed virtual keyboard is. The virtual keyboard interface is displayed in a semi-transparent state, mainly to reduce the interference to the user when the user does not want to switch from the handwriting input interface to the virtual keyboard interface. .

Step 502: Acquire the touch event of the touch display that is pre-displayed with the virtual keyboard interface.

In step 502, the touch operation performed by the touch event representation of the touch display of the virtual keyboard interface is displayed again, and the operation performed after the operation of the touch screen represented by the last acquired touch event is performed.

Step 503: Determine whether the operation performed by the touch screen represented by the touch event that is acquired again satisfies the second switching condition. If yes, go to step 504. If no, go to step 505.

Step 504: Switch the virtual keyboard interface displayed with transparency greater than the set value to the virtual keyboard interface of the non-transparent display.

In the step 504, the manner in which the handwriting input interface of the touch display is switched to the virtual keyboard interface is an existing function of the touch display device, and details are not described herein again.

Step 505: Restore the touch screen to a handwriting input interface.

At this point, the process of controlling the touch show switching ends.

In the above step 503, the second switching condition refers to a condition that the touch display needs to be switched from the handwriting input interface to the virtual keyboard interface, and the second switching condition may be as follows: the setting on the virtual keyboard interface of the touch preview pre-display The set button is clicked to set the number of times, wherein the set button can be 1 button, and the number of times of being clicked can be multiple times, for example:

When the case on the translucent virtual keyboard is clicked 5 times in a row, after selecting 5 letters, it automatically switches to the virtual keyboard interface. Here, the clicked letters are not set in advance, and the user can continuously input according to the Chinese character pinyin to be input, and the number of consecutive clicks can be set.

When the fixed letters on the virtual keyboard are continuously clicked in the set order (for example: ABCD), the virtual keyboard interface is automatically switched; the fixed letters can be set, and the number of selected letters can be flexibly set, for example, 4-8 letter.

The specific way can be set flexibly, no longer here - enumeration.

According to the foregoing third embodiment of the present invention, when the user inputs information by using the handwriting input interface, if the user wishes to input information using the virtual keyboard interface, the input interface is not changed to the virtual keyboard interface by touching the shortcut button or entering the input interface setting window. Instead, click on the touch screen directly. When the system finds that the user is clicking, the virtual keyboard is rendered in a semi-transparent manner, and the user can click the designated button on the semi-transparent keyboard. Once the click rule meets the set switching condition requirements, the input interface is automatically switched to the virtual keyboard interface, the virtual keyboard is fully rendered, and the characters that the user has entered are retained.
