A method and device for switching an input interface

technical field

The invention relates to the technical field of electronic equipment control, in particular to a method and device for switching an input interface.

Background technique

With the continuous development and improvement of touch screen technology, the touch screen technology is more and more widely used in electronic devices, for example, touch screen mobile phones, touch screen e-readers, and the like. The application of touch screen technology in electronic equipment improves and improves the functions of electronic equipment. Therefore, touch screen equipment has gradually become a development trend of electronic equipment.

The application of touch screen technology in electronic equipment is gradually integrated with various functions of electronic equipment. For example, electronic equipment obtains external operation information on electronic equipment through the touch screen, and controls electronic equipment according to the acquired operation information. A common application is to provide a user with an input interface for inputting information through a touch screen, instead of a traditional physical keyboard input interface. The input interface provided through the touch screen mainly includes a virtual keyboard interface and a handwriting input interface. The virtual keyboard interface mainly virtualizes a virtual keyboard interface including various keys on the touch screen of an electronic device. With the layout of the traditional physical keyboard, users can click the corresponding buttons on the virtual keyboard interface to realize information input; the handwriting input interface, compared with the virtual keyboard interface, reduces the restrictions on user input by the buttons, and the user can click on the handwriting input interface. Enter information directly by handwriting.

At present, a touch screen device can generally support a virtual keyboard interface and a handwriting input interface at the same time, so as to improve the applicability of the touch screen device and satisfy input habits of different users. In a touch screen device that supports a virtual keyboard interface and a handwriting input interface at the same time, since the input method of the virtual keyboard interface is similar to that of a traditional physical keyboard, the virtual keyboard interface is generally used as the default input interface of the touch screen device, that is, the user needs to provide When a touch screen device inputs information, the virtual keyboard interface is usually displayed first. If the user wishes to perform handwriting input, the virtual keyboard interface can be manually switched to the handwriting input interface, wherein the user manually switches the virtual keyboard interface to the handwriting input interface , mainly through shortcut keys, that is, define a specific key on the virtual keyboard as a shortcut key for switching, and the user can switch the input interface from the virtual keyboard interface to the handwriting input interface by clicking the shortcut key. This switching method realized by shortcut keys reduces the complexity of the user switching the input interface, but in practical applications, there are the following problems:

On the one hand, the above switching method requires the user to memorize the shortcut keys provided by the touch screen device to switch from the virtual keyboard interface to the handwriting input interface. The shortcut keys provided are also different. If the user forgets or misremembers the shortcut key for switching, the switching may fail;

On the other hand, the size of the touch screen of a touch screen device is limited, each key of the virtual keyboard usually occupies a relatively small area, and the position of each key is relatively compact. In this case, when the user clicks a shortcut key, the clicked area and There may be deviations in the area of the shortcut keys, which may cause the touch screen to fail to accurately sense the user's click operation on the shortcut keys. operation, resulting in switching failure.

To sum up, in the prior art, when switching the input interface of the touch screen from the virtual keyboard interface to the handwriting input interface, there is a problem that the switching fails due to reasons such as the user forgets the shortcut key or makes a wrong operation, and the success rate of the switching is low.

Detailed ways

In order to provide an implementation plan for improving the success rate of switching input interfaces of touch screen devices, embodiments of the present invention provide a method and device for switching input interfaces. The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that The preferred embodiments described here are only used to illustrate and explain the present invention, not to limit the present 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 one

Embodiment 1 of the present invention provides a method for switching input interfaces, and the method is applicable to touch-screen electronic devices, such as touch-screen mobile phones, touch-screen electronic readers, and the like. The touch screen electronic device can automatically determine whether to switch the touch screen to the handwriting input interface based on the acquired sliding track information of the touch screen being slid.

Fig. 1 shows a schematic flow diagram of implementing the switching of the input interface provided by Embodiment 1 of the present invention. As shown in Fig. 1, the process of realizing the switching of the input interface mainly includes the following steps:

Step 101. Obtain the sliding track information of the sliding operation performed on the touch screen displaying the virtual keyboard interface, and the sliding track information is used to represent the sliding track corresponding to the sliding operation.

In this step 101, when the touch screen is in the virtual keyboard interface, if the user needs to enter the handwriting input interface, then directly perform a sliding operation on the touch screen, and obtain the sliding track information of the area where the touch screen is slid according to the performed sliding operation. The trajectory information generally includes the coordinate values of each point on the sliding trajectory, and preferably may include generation time information of each point on the sliding trajectory.

Step 102. Select a set number of points from the sliding track corresponding to the sliding operation represented by the sliding track information.

In this step 102, the set number is greater than or equal to 2, and the selected point is specifically a pixel point on the touch screen. According to the sliding track information, the starting point or ending point of the sliding track corresponding to the sliding operation can be directly determined. Considering that when the sliding track is a similar situation of a circle, the starting point and the ending point of the sliding track coincide, so this technology In the scheme, when the set number of points selected on the sliding track corresponding to the sliding operation is 2, the selected points do not include the starting point and the ending point of the sliding track at the same time, that is, one point can be selected from the starting point or the ending point One point, the other point can choose any point on the sliding track except the starting point and the ending point; or, both points can choose a point on the sliding track except the starting point and the ending point. When the set number of selected points on the slide track corresponding to the slide operation is greater than 2, the selectable points include any point on the slide track.

Step 103, when it is determined that the distance between at least two points among the set number of points is greater than the set threshold, switch the virtual keyboard interface displayed on the touch screen to a handwriting input interface.

In this step 103, after selecting a set number of points on the sliding track corresponding to the sliding operation, the distance between two points is further calculated according to the coordinate values of the selected points. In a preferred embodiment, It can calculate the distance between two adjacent points on the sliding trajectory of the selected point. If the calculated distance is greater than the set threshold, it can be determined to switch the virtual keyboard interface displayed on the touch screen to the handwriting input interface. , there is no need to continue to calculate the distance between other adjacent points, so as to reduce the calculation amount when determining the distance between the selected points and improve the switching efficiency.

In step 103, the set threshold can be determined according to the size of the touch screen, for example, for a general mobile phone screen, a value between 5 and 10 pixels can be selected.

So far, the process of implementing the switching of the input interface ends.

Through the process corresponding to Figure 1, when the touch screen displays the virtual keyboard interface, according to the obtained sliding track information of the touch screen where the sliding operation is performed, a set number of points are selected on the sliding track corresponding to the sliding operation, and the selected When the distance between at least two points among the set number of points is greater than the set threshold, the virtual keyboard interface displayed on the touch screen is switched to a handwriting input interface. According to this technical solution, the touch screen electronic device can actively switch the virtual keyboard input interface of the touch screen to the handwriting input interface according to the sliding track information of the touch screen being slid. The problem of switching failure caused by forgetting or misremembering the shortcut key for switching the input interface. On the other hand, when the technical solution realizes the operation of switching the touch screen input interface, there is no need to click the shortcut key, which reduces the need for the user to operate the shortcut key area. Limitation, thereby overcoming the switching failure problem caused by the mismatch between the user operation sensed by the touch screen and the user's actual operation, thereby improving the success rate of switching the input interface of the touch screen device.

In step 102 included in the process corresponding to FIG. 1 , a set number of points are selected from the sliding trajectory corresponding to the sliding operation represented by the sliding trajectory information. The following preferred implementation methods can be implemented. When the following preferred implementation methods are implemented in detail, It can be combined with each other to select a set number of points on the interactive trajectory, as follows:

Preferred Embodiment One

In the first preferred embodiment, a set number of points located at the center of the track width of the slide track are selected from the slide track corresponding to the slide operation represented by the slide track information of the slide operation performed on the touch screen.

The track width of the sliding track refers to the width of the sliding track. Since the user's touch operation on the touch screen is generally performed by a finger or a touch pen, the touch operation on the touch screen usually corresponds to an area on the touch screen, including multiple points. Therefore, in order In order to determine the distance of the selected points, in the first preferred embodiment, a set number of points can be selected from the points at the center of the track width. Fig. 2 shows a schematic diagram of the sliding track, as shown in Fig. 2, there are multiple points on the track width of the sliding track of the sliding operation, and the first central point shown in Fig. 2 is a point located at the center of the track width of the sliding track, According to the set number, the point at the center of the track width corresponding to other positions of the sliding track can be continuously selected, such as the second center point shown in FIG. 2 .

Preferred Embodiment Two

In the second preferred embodiment, according to the generation time information corresponding to each point on the slide track corresponding to the slide operation represented by the slide track information, a set number of points corresponding to different generation times are selected from the slide track.

The sliding trajectory information includes the generation time information of each point on the sliding trajectory corresponding to the sliding operation. The points corresponding to the generation time information are recorded in the order of generation time, and will be used to represent the coordinates of the specific positions of the points corresponding to the generation time information value is recorded together. According to the above-mentioned generation time information, a set number of points on the sliding track corresponding to the generation time information can be arbitrarily selected. Preferably, according to the generation time sequence of each point on the sliding track, from the generation time corresponding to the starting point of the sliding track to the end Select a set number of points with different generation times in sequence from the generation time corresponding to the point, or select a set number of points with different generation times in sequence from the generation time corresponding to the end point of the sliding trajectory to the generation time corresponding to the start point . The above method of selecting a set number of points with different generation times according to the generation time sequence of each point of the sliding track is a preferred implementation of the first embodiment, and is not limited to the above method.

In the second preferred embodiment, considering that the sliding track corresponding to the sliding operation has a certain track width (as shown in FIG. 2 ), multiple points may correspond to the same generation time. When pointing, preferably, based on the above-mentioned preferred embodiment 1, according to the generation time information corresponding to each point on the slide track corresponding to the slide operation represented by the slide track information, select the track width center of the slide track from the slide track, and correspond to a set number of points at different generation times. However, it is not limited to the above solution, and one point may be arbitrarily selected among multiple points corresponding to the same generation time.

In the second preferred embodiment, when a set number of points corresponding to different generation times are selected from the sliding track, the generation time of each point is recorded together with the coordinate value of each point. Therefore, when selecting different generation times in the generation time information, it only involves From the calculation of reading the generation time information, according to the corresponding relationship between each point on the sliding track and the generation time, the point corresponding to the generation time can be directly obtained. It can be seen that the technical solution corresponding to the second preferred embodiment has a small amount of calculation and can improve the touch screen. The rate at which the electronic device processes the sliding track information corresponding to the sliding operation.

Preferred Embodiment Three

In the third preferred embodiment, on the basis of the second preferred embodiment above, when selecting a set number of points corresponding to different generation times from the slide track, it is preferable to select points corresponding to different times from the slide track corresponding to the slide operation. , and there are a set number of points with a set time interval between adjacent points.

In the above technical solution, after the first point on the sliding track is selected, according to the set time interval, the time interval from the first generation time corresponding to the first point is determined as the second generation time of the set time interval , and select the point corresponding to the second generation time as the second point, and so on, until a set number of points is selected, where the first point and the second point are only used to distinguish different points, not as points order constraints. FIG. 3 shows a schematic diagram of selecting three points on a sliding track corresponding to a sliding operation. As shown in Figure 3, after the first point is selected, according to the set time interval, it is determined that the time interval from the first generation time corresponding to the first point is the second generation time corresponding to the second generation time of the set time interval. Two points, and based on the second generation time, determine the third point corresponding to the third generation time. The second point and the third point shown in Figure 2 are determined according to the set time interval, so the time interval between the generation time corresponding to the first point and the second point, and the generation time corresponding to the second point and the third point The time intervals are the same, because the speed at which the user performs a sliding operation on the touch screen is not uniform, and the distance between two adjacent points of the above three points is not necessarily the same.

Preferred Embodiment Four

In the preferred embodiment 4, a set number of points corresponding to different generation times are selected from the slide track corresponding to the slide operation based on the set position points on the slide track corresponding to the slide operation.

In the above technical solution, the first point is first set on the sliding track corresponding to the sliding operation, and this point can be a point at any specific position on the set sliding track, or it can be within a certain position range set on the sliding track Then, based on the first point of the set position, select other set points corresponding to different generation times, among which, for points corresponding to different generation times, the adjacent points on the sliding track can be equal to The intervals can also be unequal intervals, or the time intervals between adjacent points increase or decrease. The set number of points determined according to the above description corresponds to different generation times, and there is no special limitation on the time interval between the generation times corresponding to two adjacent points.

Figure 4 shows a schematic diagram of selecting four points on the sliding track corresponding to the sliding operation. Three points with increasing time intervals from the first point. In the above-mentioned Figure 4, the scheme of determining the second point, the third point and the fourth point corresponding to different generation times based on the first point of the set position on the sliding track is the preferred scheme of the first embodiment, but it is not limited in this implementation.
