Detailed ways

In various embodiments of the present invention, by acquiring the current touch operation information on the touch screen, the level to which the current touch operation information belongs is determined according to the touch operation information and the stored touch operation information threshold interval, and according to the Level adjustments on the touchscreen keyboard.

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

The present invention realizes the automatic adjustment method of a kind of touch screen keyboard, as shown in Figure 1, this method comprises the following several steps:

Step 101: The touch screen acquires current touch operation information.

Taking the Android (Android) operating system as an example below, the present invention will be further described in detail.

Specifically, when the user uses the touch screen keyboard, touches the screen, and the Android operating system analyzes the touch event. Described parsing specifically comprises: Andrews android layer is processed through event concentrator EventHub of local layer frame Nativeframwork and the keyboard input device KeyInputDevice of Java layer framework Java framework --> key event KeyEvent (be original input event RawInputEvent --> mobile event MotionEvent when sliding ) after processing, report the touch event to the application in the form of: key down onKeyDown/release key onKeyUp or touch event onTouchEvent/trackball event onTrackballEvent, and report the MotionEvent object containing the current touch operation information.

MotionEvent contains all information related to the current touch operation, including the value of the touch area used to determine the thickness of the touch track. For example, use size to indicate the touch area of the touch track. When the touch screen keyboard of the touch screen keyboard is processing touch events, the value of the touch area size is obtained through the getSize() method in MotionEvent.

Step 102: The processor determines the level to which the current touch operation information belongs according to the touch operation information and the stored touch operation information threshold interval.

The threshold intervals corresponding to the size values are stored in advance, for example, the size value corresponding to the first interval is 0-0.3, the size value corresponding to the second interval is 0.3-0.6, and the size value corresponding to the third interval is 0.6-1. This embodiment only sets three example intervals. In other embodiments, in order to avoid the situation that the touch screen keyboard area exceeds the touch screen range or the touch screen keyboard area covers the text input area, the touch screen keyboard can be called according to different screen sizes and application scenarios , to increase or decrease the corresponding threshold interval.

Compare the size value acquired in step 101 with the stored threshold interval, determine the interval where the current size is located, and determine the level of the touch track according to the interval where the current size is located, for example, the touch track corresponding to the first interval is normal , represented by a level value of 1, the touch track corresponding to the second interval is thicker, represented by a level value of 2, the touch track corresponding to the third interval is represented by a level value of 3, and the obtained determination result is saved.

Step 103: The processor adjusts the touch screen keyboard according to the level to which the current touch operation information belongs.

When the user starts to input on the touch screen keyboard, the touch screen keyboard receives the key event and processes it, obtains the current touch screen information and the current touch screen keyboard information, determines the touch screen keyboard adjustment parameters according to the current touch screen information and the current touch screen keyboard information, and adjusts the parameters according to the touch screen keyboard Adjust the touch screen keyboard with the level of the current touch operation information obtained in step 102. The adjustment content includes increasing or decreasing the height of the keyboard, expanding or reducing the size of the keys, expanding or reducing the response area of the keys, etc.

Below, the adjustment of the touch screen keyboard will be described in detail in conjunction with the accompanying drawings.

In the Android system, the touch screen keyboard configuration file is preset with touch screen keyboard height keyboardHeight, key width keyWidth, key height keyHeight, horizontal spacing horizontalGap, vertical spacing verticalGap and other information. The value of these information can be obtained by reading the configuration file, for example, the corresponding configuration value can be obtained through the ResourceUtils.getDimensionOrFraction method for obtaining dimensions or fractions in the resource utilities provided by the Android system. Obtain current touch screen information such as touch screen height screenHeight, touch screen width screenWidth, and input area height inputHeight from the Android system. The touch screen keyboard adjustment parameters are determined according to the acquired current touch screen information and touch screen keyboard information, and the touch screen keyboard is adjusted according to the determined adjustment parameters and the level of the current touch operation information determined in step 102 .

As shown in FIG. 2 , it is a schematic diagram of increasing the height of the keyboard of the touch screen according to the embodiment of the present invention.

Obtain the height of the touch screen keyboard stored in the touch screen keyboard configuration file as keyboardHeight. According to the determined current touch track corresponding level value is 2, that is, the touch track greater than the preset is a normal level value of 1. It is determined that the touch screen keyboard needs to be adjusted .

Determine the touch screen keyboard adjustment parameters according to the current touch screen keyboard height keyboardHeight, touch screen height screenHeight and input area height inputHeight, that is, the height H2 that the touch screen keyboard can increase is:

H2=screenHeight-keyboardHeight–inputHeight

Adjust the touch screen keyboard height to keyboardHeight+H2;

Record the new height keyboardHeight=keyboardHeight+H2 of the touch screen keyboard.

When the value of H2 that can increase the height of the touch screen keyboard is 0, that is, according to the current total height of the touch screen and the height of the input area, there is no room to increase the height of the touch screen, you can expand the height of the touch screen keyboard while maintaining the original height of the touch screen keyboard The size of the touch-screen keyboard keys can be used to improve the input accuracy, and the size of the touch-screen keyboard keys can also be enlarged while increasing the height of the touch-screen keyboard.

As shown in FIG. 3 , it is a schematic diagram of expanding the keys of the touch screen keyboard according to the embodiment of the present invention.

Expand the touch screen keyboard keys are divided into two types: horizontal direction and vertical direction, among them, the total space that can be expanded vertically in the vertical direction of the touch screen keyboard can be used

vertical=keyboardHeight-((keyHeight*key rows)+(verticalGap*key rows))

Calculate, where keyboardHeight is the height of the current touch screen keyboard, keyHeight is the height of the current touch screen keyboard keys, and verticalGap is the vertical distance between the current touch screen keyboard keys.

On average, the vertical space of each touch button can be expanded nvertical can be used

nvertical=vertical/key row number

Calculation.

Correspondingly, the nhorizontal space that can be expanded horizontally for each touch button can be used

nhorizontal=horizontal/number of key columns

Calculation.

Among them, the horizontally expandable total space horizontal can be used

horizontal=keyboardWidth-((keyWidth*key columns)+(horizontalGap*key columns))

Calculate, where keyboardWidth is the width of the current touch screen keyboard, keyWidth is the width of the current touch screen keyboard keys, and horizontalGap is the horizontal spacing between the current touch screen keyboard keys.

According to the determination result in step 102, for example, the corresponding level value of the touch track determined according to the current touch area is 2, that is, the level value greater than the preset touch track is normal level value 1, then the high keyHeight of the key, the wide keyWidth of the key Make adjustments. Specifically, adjust the width nkeyWidth of the key to:

nkeyWidth=keyWidth+nhorizontal

Adjust the height of the key nkeyHeight as:

nkeyHeight=keyHeight+nvertical

After adjustment, save the new touch-screen keyboard key width nkeyWidth and touch-screen keyboard key height nkeyHeight as the current touch-screen keyboard key width and height.

What is shown in FIG. 3 is only an example of enlarging one touch screen key, and in other embodiments of the present invention, multiple or all touch screen keys may be adjusted simultaneously.

When the expandable vertical or horizontal space of the touch screen keyboard keys is 0, that is, according to the current touch screen height, the height of the input area and the interval between the touch screen keyboard keys, there is no space to increase the height of the touch screen keyboard or expand the size of the touch screen keyboard keys, The input accuracy can be improved by expanding the response area of the touch screen keyboard keys while keeping the height of the original touch screen keyboard unchanged, or the response area of the touch screen keyboard keys can be expanded while expanding the size of the touch screen keyboard keys.

As shown in FIG. 4 , it is a schematic diagram of expanding the response area of the touch screen keyboard according to the embodiment of the present invention.

According to the determination result in step 102, specifically, for example, according to the current touch area shown in the black dotted shaded area in FIG. If the value is 1, it is determined to adjust the original response area of the touch screen keyboard shown in the mesh shaded area in Figure 4, for example, to expand the original response area of the touch screen keyboard shown in the mesh shaded area in Figure 4 according to the preset ratio Specifically, the response area of the touch screen keyboard is set to 130% of the original response area, or 150% of the original response area, or 200% of the original response area in combination with the corresponding level value of the touch track determined in step 102. The adjusted touch screen keyboard response area is shown in the slanted shaded area in Figure 4, so that the touch screen keyboard can more accurately respond to the user's touch key input with thicker fingers, improving input accuracy and user experience.

If the touch track changes when the user uses it next time, the corresponding touch track level is determined according to the newly acquired size value, and the touch screen keyboard is adjusted according to the determined value.

In another embodiment of the present invention, it is considered that if the touch screen keyboard is adjusted during the user input process, the problem of input errors may be caused due to sudden changes in key positions. In order to avoid this situation, the touch screen keyboard can be automatically adjusted when the touch screen keyboard is reloaded (for example, when the touch screen keyboard is turned off and then turned on again, the landscape and portrait screens are switched, etc.).
