Description

Method for realizing intelligent software keyboard input on screen of electronic equipment

technical field

The invention relates to the field of electronic equipment screens, in particular to the technical field of electronic equipment screen information input, in particular to a method for realizing intelligent software keyboard input on the electronic equipment screen.

Background technique

In modern life, with the continuous development of integrated circuit technology, various electronic devices with touch screens have appeared. ), due to the constraints of factors such as volume and manufacturing cost, it is impossible to be equipped with a perfect hardware keyboard, so the input on this type of equipment is usually completed by software simulation.

Generally, in the prior art, traditional software keyboards bring great inconvenience to users. This is mainly because the area of the touch screen is small and there are many contents to choose from, so the corresponding screen selection area is also small. This makes it impossible for the user to directly accurately click the selection area on the screen with the finger to input, but often needs to rely on other tools with smaller touch resolution, such as a stylus.

In most cases, this requires the user to use both hands simultaneously: one hand to hold the electronic device, and the other hand to tap the touchscreen with a stylus for input. Even so, in some environments, such as a driving car, even with the help of other tools, the user may still be unable to accurately select the content to be input due to the influence of the environment, such as vibration.

Please refer to FIG. 1 , generally on a similar device 100 equipped with a small-area touch screen, the main input is done through the software keyboard 102 . The user completes the input by clicking a key on the keyboard, such as key 104 . And common touch screen software promptly completes the selection of input content when the user presses and clicks the key on the software keyboard. In order to achieve the purpose of precise input, the user usually needs to use some auxiliary tools with a high click resolution, such as a stylus, to perform input. Even so, in some cases, such as when the user is in a bumpy car that is moving, the user may still click the content on the keyboard by mistake for various reasons, resulting in misoperation.

On the other hand, the traditional software keyboard input method only judges the position of the pressed contact, so the amount of information input at one time is only limited to the screen size of the keyboard. For example, on a keyboard with a size of 120×240 pixels, the amount of information is 120×240=28800 (touch points). If the size of each button is 40*40=1600 pixels, only 18 buttons can be accommodated, which is far from meeting the needs of daily input.

Detailed ways

In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

First of all, it should be noted that the method of the present invention is applicable to any electronic device screen with an indication input system, including but not limited to pressure-sensitive touch screens, electromagnetic induction touch screens, and mouse-indicative touch screens. The common feature of these screens is a touch point with coordinate position information and its action equivalent to a press and release operation. For example, the coordinate position information is contained when the touch screen is pressed, and the coordinate position information is also contained when the left mouse button is pressed.

The specific implementation manner of the present invention will be described below by taking a touch screen as an example. However, these implementation methods can be correspondingly applied to other screens that meet the above requirements. For example, the operation of "pressing a touch point on a certain focus area of the screen" may correspond to "moving the mouse to a certain focus area of the screen and pressing the left button". If there is a screen using other operation modes, as long as it has the concept of contact points with coordinate information and press/release operations, it can be applied to the software keyboard of the present invention.

First please refer to Fig. 2, 3a and 3b, the method for realizing intelligent software keyboard input on the electronic device screen, its main feature is that the described method includes the following steps:

(1) The system divides the keyboard area on the touch screen into several focus areas and several content areas; the content displayed in the focus area is: the content information of all associated content areas, or can display all associated content areas The description information of the common features of the content; the content area also includes a fuzzy area that can contain various possible input content;

(2) Establishing an association relationship between the several focus areas and several content areas; the association relationship may be: a peripheral principle association relationship, that is, a focus area is associated with all content areas around the focus area;

Can also be:

Overlap principle association relationship, that is, a focus area is associated with all content areas that the focus area overlaps;

At the same time, the above-mentioned association relationship may also include:

A focus area is associated with the corresponding lowercase/uppercase letters in all content areas surrounding the focus area;

(3) The system performs the keyboard area initialization operation, and the keyboard area on the touch screen is set in the focus selection mode;

(4) The system continuously detects the operation of the user touching the screen;

(5) If the system detects that the user touches the screen, dynamically switch the keyboard area on the touch screen to the content selection mode, and associate the touch focus area where the user touches the screen point perceived by the touch screen according to the association relationship The associated content area performs a dynamic layout adjustment display processing operation; the dynamic layout adjustment display processing operation can be an enlarged surrounding layout display processing operation, specifically:

Centering on the screen point touched by the user, maintain the original layout relationship of the associated content area to zoom in and display according to the magnification factor preset by the system, and there is no overlap between the various content areas; at the same time, if the user touches the screen point on On the edge position of the touch screen, the enlarged display of the associated content area is limited to the inner side of the screen edge, so as to avoid exceeding the display boundary of the touch screen;

The dynamic layout adjustment display processing operation may also be a parallel layout display processing operation, specifically:

Centering on the point where the user touches the screen, the associated content areas are arranged and displayed in parallel according to the preset sequence rules, and there is no overlap between the various content areas; at the same time, the associated content areas arranged in parallel can also be The area is enlarged and displayed according to the magnification preset by the system; moreover, if the user touches the screen and points on the edge of the touch screen, the parallel arrangement display of the associated content area is limited to the inner side of the screen edge to avoid display beyond the touch screen boundary;

After the above-mentioned step (5), the following steps can also be included:

(51) The system continuously detects the user's operation of moving the position of the screen touch point, and performs a dynamic selection display processing operation according to the movement of the screen touch point; the dynamic selection display processing operation can be:

The system dynamically highlights the content area where the moving position of the screen touch point is located, and normally displays other content areas;

The dynamic selection display processing operation may also include the following steps:

(a) The system sets a corresponding prompt area at the preset corresponding position according to each content area, and displays the content of the corresponding content area in each prompt area; moreover, the system can also set each content area to be invisible;

(b) The system dynamically highlights the prompt area corresponding to the content area where the moving position of the screen touch point is located, and normally displays the prompt area corresponding to other content areas;

The dynamic selection display processing operation can also be:

The system dynamically sets the corresponding prompt area at the preset corresponding position according to the content area where the moving position of the screen touch point is located, and displays the content of the corresponding content area in the prompt area;

(6) The system continuously detects the operation of the user lifting the touch point;

(7) If the system detects that the user lifts the touch point, the content in the content area where the screen touch point is separated from the position sensed by the touch screen is used as the keyboard input information, including the following steps:

(a) The system judges whether the content area where the screen touch point breaks away is a fuzzy area;

(b) if not, directly input the content of the content area into the system, and return;

(c) If yes, the system combines the characters previously input by the user with all possible input content in the fuzzy area, and searches out possible words according to the preset dictionary rules, arranges and displays them according to the preset arrangement rules, and prompts the user Select Confirm;

(d) The system will input the content of the confirmation selection into the system according to the user's selection;

(8) The system dynamically switches the keyboard area on the touch screen to the focus selection mode, and returns to the above step (4).

In summary, the core idea of the present invention is as follows:

Divide the keyboard area into several focus areas and several content areas, and there is an association between the focus area and the content area, that is, one focus area is associated with several content areas, and the keyboard is divided into two working modes: focus selection mode 202 And the content selection mode 204, when the user touches the screen before and at the moment of touching the screen, the keyboard is in the focus selection mode; at this time, the keyboard senses the focus area where the user touches the screen point, and dynamically switches the keyboard mode to the content selection mode 206, which will be connected with the content selection mode 206. The content area associated with the focus area is rearranged and enlarged for display. By moving the touch point on the screen, the user can choose between the displayed content areas. Once the touch point on the screen leaves the keyboard surface, that is, the user lifts the touch point, the keyboard senses the content area where the user lifts the point, and takes the content of the content area as input; meanwhile, the keyboard is switched back to the focus selection mode 208 .

In practical applications, in the focus selection mode, the keyboard is divided into several focus areas, and each focus area is a touch signal perceived by the user. In practical applications, a focus area can correspond to a key position that the user sees, please refer to Figure 4a, which describes a focus area distribution, but what the user actually sees is the key position shown in Figure 4b Distribution; the focus area is not equal to the actual key position, because the focus area is an area perceived by the screen and invisible to the user; while the actual visible key position is a user interface with prompts. For example, the focus area shown in FIG. 4a is slightly larger than each key position shown in FIG. 4b. This is to prevent the user's touch point from falling into the boundary of the key position and cannot input.

In the initial layout of the keyboard shown in Figure 4a, ie in the focus selection mode, the content area is not activated. When the user presses a focus area, its associated content area is activated, while other focus areas are temporarily disabled. These associated content areas undergo dynamic layout adjustments and are enlarged for display. For example, when the focus area 1 is pressed, the content selection mode shown in FIG. 5 is entered. When the user moves the touch point to the designated content area and releases it, an input is completed.

There is a correlation between the focus area and the content area, that is, one focus area is associated with several content areas. Please refer to FIG. 6 , the determination of this association relationship may follow different principles. For example, the "surrounding principle" in the following examples 1 and 2 and the "overlapping principle" in example 3.

Focus area and content area are two different concepts. The focus area is mainly used to sense the contact point of the user pressing the screen, and does not carry content information. The content area carries the actual input content (often characters, symbols, control characters, words or phrases), and is used to sense the user's contact point away from the screen and input the desired content.

In focus selection mode, the content area is not yet active, only the focus area is selectable. When the user clicks on a focus area to enter the content selection mode, the content area is activated and the focus area is temporarily disabled. At this point, the user can move the touch point to switch between content areas. When the user lifts the touch point in a content area, the content of the content area is entered.

Sometimes when the user operates with the thumb, part of the content area is covered. Please refer to FIG. 7 , in order to clearly reflect the current selection, the currently selected content may be displayed near (such as above) the content area, which is called a "prompt area".

As a special case, there can be a "blurred" area in the content area. This area can contain multiple contents, and the final input content is determined by the sequence of other inputs. For example, when inputting an English word "what", when the user inputs the letter "a", the content area of the "fuzzy" input contains both "a" and "s". But by judging the letter sequences "w" and "h" input before this, and the letter "t" input after that, the final input can be determined as "a". A specific description will be given in Example 3 below.

The software keyboard design scheme based on the present invention will be described below in conjunction with several embodiments. These embodiments are based on English input, but the method of the present invention is not limited to language types, and can also be applied to input in various languages such as Chinese, Japanese, and German. Software keyboard versions meeting different language requirements can be designed only by making minor adjustments to the keyboard layout described in the following embodiments.

Example 1

焦点区域和内容区域

focus area and content area

Please refer to Figs. 8a, 8b, and 8c, the keyboard layout described therein bears 26 letters from A to Z. The keyboard 330 describes the keyboard layout seen by the user before pressing the screen; the keyboard 310 describes the division of the focus area of the keyboard; the keyboard 320 describes the division of the content area of the keyboard. In this example, the division of the focus area is exactly the same as the division of the content area. Therefore, there are 26 focus areas and 26 content areas in the keyboard layout, and the contents carried are 26 letters from A to Z. But before the user presses any key, the keyboard is in the focus selection mode, so all content areas have not been activated, and the keyboard 310 only serves as a prompt. Meanwhile, the area 340 seen by the user covers a focus area 350 and a content area 360 .

焦点区域和内容区域的关联

Association of focus area and content area

In this example, the relationship between the focus area and the content area is determined according to the "surrounding principle". That is, a focus area is associated with its surrounding content areas. Please refer to Figures 9a, 9b which illustrate this association. The coordinate system 502 describes the content area associated with the focus area 510, and the coordinate system 504 describes the content area associated with the focus area 510'.

For example, according to the surrounding principle, the content areas associated with the focus area 510' in FIG. 9b are 510', 512', 514', 516', 518', 520' and 522'. The input contents they represent are: 'F', 'D', 'G', 'R', 'T', 'C' and 'V'.

内容区域的动态布局调整

Dynamic layout adjustments for content areas

Before the user presses a key, the keyboard works in focus selection mode. At this time, the keyboard determines the corresponding focus area according to the position where the user touches the screen. Once the user presses a key, the focus area where the touch point is located can be determined. The keyboard dynamically calculates the content area corresponding to the focus area according to the set association principle between the focus area and the content area, and will re-layout these corresponding content areas to help users conveniently move between content areas. Moving the touch point to select the expected input content is called "dynamic layout adjustment of the content area".

Dynamic layout adjustments for content areas can follow different layout methods. In this embodiment, the dynamic layout adjustment of the active content area follows the "enlarging surrounding layout method", as shown in the coordinate system 504 . For example, when the user presses the "F" key in the keyboard described in 300, the "F" key and the surrounding content area are enlarged by 1.5 times. The magnification factor of the active content area can be determined according to the specific situation of the keyboard, but in principle there is no overlap between the magnified and rearranged content areas, which avoids input ambiguity caused by the user releasing the touch screen on the overlapping area. At the same time, at the edge position, for example, when the user presses the "A" key, the magnification of its content area is limited to the right side of the screen edge, so as not to exceed the boundary.

内容选择模式

content selection mode

After the dynamic layout adjustment of the content area is completed, the keyboard is switched to the content selection mode. In the content selection mode, the user selects input by moving the position of the screen touch point to the content area corresponding to the desired input content, and then releasing the screen touch point. For example, in the coordinate system 504, if the user moves the touch point on the screen to 518' and then releases the touch point on the screen, the keyboard will take the content 'T' represented by 518' as the final input content.

Example 2

焦点区域和内容区域

focus area and content area

The keyboard layout, focus area, and content area in this embodiment are exactly the same as in Example 1: the keyboard layout described therein bears 26 letters from A to Z. The keyboard 310 describes the division of the focus area for the keyboard, and the keyboard 320 describes the division of the content area for the keyboard.

焦点区域和内容区域的关联

Association of focus area and content area

This embodiment is the same as Embodiment 1, and the association between the content area and the focus area follows the "surrounding principle".

内容区域的动态布局调整

Dynamic layout adjustments for content areas

In this example, the dynamic layout adjustment of the content area follows the "parallel layout method". Please refer to FIG. 9 c , for example, the coordinate system 506 describes the dynamically adjusted layout of the content area when the user presses the “F” key where the focus area is located. The 7 content areas surrounding the "F" key are arranged in a row in parallel. At the same time, all content areas are magnified by 1.5 times, and the magnification can be adjusted according to the actual situation.

In a typical arrangement, the coordinates of the position where the user is currently pressing the screen will become the default center position of the currently selected content area, and the position of 530 is calculated based on this principle. The rest of the content areas are arranged around 530 and have the same Y coordinate value as it, that is, "parallel layout". The two directly adjacent content areas 512 ′, 514 ′ on the left and right of the content area 510 ′ are respectively placed at the left and right positions of 530 : 532 , 534 ; The left position: 536; the content area 518' directly adjacent to the upper right is placed at the right position of 534: 538; the content area 520' directly adjacent to the lower left is placed at the left position of 536: 540; The immediately lower right adjacent content area 522 ′ is positioned to the right of 538 : 542 .

Referring to FIG. 10 again, when the selected focus area is located at the edge of the screen, the content area can be dynamically adjusted to one side. For example, when the user presses the "A" key, since "A" is located at the leftmost end of the screen, the layout of the content area is all adjusted to the right of "A", where the dot 1001 represents the current touch point position.

提示区域

Prompt area

In this example, the content area after the dynamic layout can be designed to be invisible, and the corresponding prompt area is displayed right above it. Please refer to Figures 10 and 11, the dotted line part is the invisible content area, when the touch point moves over the content area, the corresponding character in the prompt area is highlighted. In this way, it is possible to prevent the user from covering the selected content area when inputting with a finger, where the dots 1001 and 1002 represent the current contact positions.

The hint area is completely optional. The keyboard involved in the method of the present invention can fully realize desired functions without a prompt area, but the prompt area can effectively improve user experience, allowing the focus area and content area model of the method to fully exert its advantages. At the same time, when the prompt area appears, the content area can also be visible at the same time. Hiding the content area is only a design to avoid repetition, and does not affect the essence of the present invention.

内容选择模式

content selection mode

Similar to Embodiment 1, after the dynamic layout adjustment of the content area is completed, the keyboard is switched to the content selection mode. In the content selection mode, the user selects input by moving the position of the screen touch point to the content area corresponding to the desired input content, and then releasing the screen touch point.

Example 3

焦点区域和内容区域

focus area and content area

Please refer to FIG. 12a again, which depicts a keyboard layout actually seen by the user. At this time, the keyboard is divided into 5×3 key positions, and 26 letters from a to z and common symbols are distributed. , meanwhile, in practical application, the key position distribution of the present invention does not need to be limited to this 5×3 layout, and only a realizable example is given here. The keyboard layout is similar to the normal computer keyboard layout, the difference is that every two letters are combined into a key.

Please refer to FIG. 12b, which describes the division of the focus area for the keyboard. Each key corresponds to a focus area.

For each focus area (key), 1 to 6 content areas are associated. Please refer to Figure 12c, taking the focus area 6 as an example, in which letters a, A, s, S and symbols are associated! , a total of 5 content areas; please refer to FIG. 12d again, taking the focus area 12 as an example, letters z, Z, x, and X are associated, and a total of 4 content areas. Since it is close to the bottom of the keyboard, there is no commonly used symbol for this key position; please refer to Figure 12e again, taking the focus area 10 as an example, it is associated with letters 1, L, and a period ".", a total of 3 content areas. Of course this is only a humanized design, and the core idea of the present invention is not limited thereto.

Note that the keyboard is in focus selection mode until the user presses any key. All content areas have not been activated. Only when the user presses the focus area and the keyboard enters the content selection mode, the content area will be activated and displayed after dynamically adjusting the layout.

焦点区域和内容区域的关联

Association of focus area and content area

In this embodiment, the association relationship between the focus area and the content area is determined according to the "overlapping principle". That is, a focus area is associated with the content area it overlaps. Due to the characteristics of the keyboard layout in FIG. 12 a , there are 1 to 6 content areas overlapping each focus area on the surface covered by it, that is, there is an overlapping relationship between the focus area and the content area.

Dynamic layout adjustments for content areas

In this embodiment, the dynamic layout adjustment of the active content area follows the six-way layout principle of "upper left, upper right, left, middle, right, and lower". For example, when the user presses the focus area 6 shown in Figure 12b, the keyboard enters the content selection mode, and its content area is dynamically adjusted as shown in Figure 12f. At this time, the entire keyboard enters the content selection mode, and the entire screen area is divided into 6 content areas, while all other focus areas are temporarily invalid. When the touch point is moved to the upper left area and released, the input is a capital letter "A"; when it is moved to the right area and released, the input is a lowercase letter "s"; is the symbol "!", and so on.

The dot between "a" and "s" represents the position of the touch point when the user first presses it, so the distribution of the visible content area is relative to the position of the touch point at the time of pressing. , and at the same time, in order to avoid the "A" and "a" areas on the left being too small, it is necessary to consider reserving a space between the focus area 6 and the edge of the screen in the initial layout of the keyboard.

Similarly, when the user presses the focus area 12 shown in Figure 12b, its content area is dynamically adjusted as shown in Figure 12g. At this point, the screen area of the entire keyboard is divided into five content areas. When the touch point is moved to the left area and released, the input is the lowercase letter "z".

In Figure 12f and Figure 12g, the content area where the dot "●" 1201 between "a" and "s" is located and the content area where the dot "●" 1202 is located between "z" and "x" is "blurred " input field. For example, in Figure 12f, when the user presses the touch point and releases it at the original place, its content area can represent both "a" and "s". At this time, the character will not be input on the screen immediately, but will automatically find possible words from the dictionary according to the preceding and following characters input by the user, and prompt the user for confirmation. The "fuzzy" area can be a narrow area with a certain distance (for example, 5 pixels on the left and right) from both sides of the initial touch point, so as to avoid misjudgment due to shaking and other reasons.

For example, please refer to Fig. 13a, when the user presses and releases the focus areas 13 (c, v), 6 (a, s), 14 (b, n) , the screen candidate word list will automatically pop up words such as "can", "cab", and "vanity" (which can be arranged in order of word frequency) for the user to confirm.

In addition, users can also perform "fuzzy" and precise mixed input, which can greatly reduce the probability of repeated codes and facilitate the input of custom vocabulary.

For example, please refer to shown in Figure 13b again, when the user will input the word "tea", when he presses (and directly releases) the keys (t, y), (e, r), (a, s) in sequence , only the high-frequency words "yes", "yesterday", and "yeah" may appear in the selection area, and he needs to perform operations such as turning pages to find the word "tea". This is mainly because there are repeated codes for these words.

But if the user enters the precise input "t" (after pressing the key (t, y), move to the content area representing "t" on the left and release it), and then fuzzy input "e" and "a" (press Press the key (e, r), (a, s) and release it at the original position), and "tea" will appear directly in the selection area, as shown in Figure 13c. This is because the user combines precise input ("t"), allowing the input method to narrow the search and improve the accuracy of the word guess.

Referring to Fig. 13d again, when the user wants to input a custom word, such as the word "ETA", if fuzzy input is used, the user will not be able to select the desired word because there is no such word in the thesaurus. At this time, if you want to switch to the letter mode or enter the correction mode, the input efficiency is very low. However, in the keyboard designed by the present invention, due to the concept of the content area, the user can accurately input the word by pressing the focus and moving to the designated content area and releasing it. For example, to enter the custom word "ETA", the user can do the following:

(1) Press the key (b, n) and move to the upper left content area "E" and release it;

(2) Press the key (t, y) and move to the upper left content area "T" and release it;

(3) Press the key (a, s) and move to the upper left content area "A" and release it.

At this point, the custom word "ETA" will automatically appear in the word selection area. The user can click to select the word and it will be automatically added to the thesaurus.

The fundamental reason why the method of the present invention can achieve such a combination of "precise" and "fuzzy" lies in the layout adjustment of the dynamic content area proposed by the present invention. (When the user presses the touch point and releases it, it represents "fuzzy" input; and when the user presses the touch point and moves to other content areas and releases it, it represents "precise" input.) And in the traditional input method , there is no concept of content area at all, and there is no dynamic layout adjustment of content area, so "precise" selection is impossible.

提示区域的显示

The display of the prompt area

In this embodiment, the content area may also be invisible. Therefore, the prompt area can be displayed at n pixels above the focus area (n can be adjusted according to the size of the keyboard). An example of a prompt area (the actual design need not be limited to this) is shown in Figure 14, a circular prompt box appears above the focus area, dynamically displaying the characters in the content area where the current touch point is located. For example, when the user moves to the content area where "A" is located, the character in the prompt area will be automatically displayed as "A"; when the touch point is in the "fuzzy" area, the prompt area will display "a s". Therefore, the user can clearly see the characters to be input very intuitively, and release the touch point after moving to the desired character, which is easy to learn.

Example 4

焦点区域和内容区域

focus area and content area

Please refer to Fig. 15a, which describes a keyboard layout actually seen by the user. The keyboard can be divided into 3×3 key positions, and 26 letters from a to z and common symbols are distributed. This keyboard layout is similar to a normal mobile phone keyboard.

Fig. 15b describes the division of focus areas for the keyboard, and each key corresponds to a focus area.

For each focus area (key), 1 to 10 content areas are associated. Taking focus area 2 as an example, please refer to Fig. 15c, where letters a, A, b, B, c, C and symbols are associated! , and the "fuzzy area" where the dot is located, a total of 8 content areas.

内容区域的动态布局调整

Dynamic layout adjustments for content areas

In this embodiment, when the user presses the focus area 2 shown in FIG. 15b, the keyboard enters the content selection mode, and the layout of the content area is dynamically adjusted as shown in FIG. 15d. At this point, the entire keyboard enters the content selection mode, and the entire screen area is divided into 8 content areas, while all other focus areas are temporarily invalid. When the touch point is moved to a content area and released, the input is the character corresponding to the content area.

The dot between "a" and "b" represents the position of the touch point when the user first presses it, so the distribution of the visible content area is relative to the position of the touch point at the time of pressing.

As another example, when the user presses the focus area 9 (w, x, y, z) in Fig. 15b, after entering the content selection mode, the entire keyboard is divided into 10 content area layouts as shown in Fig. 15e.

Similar to Embodiment 3, in Figure 15d and Figure 15e, the content area where the dot "●" between "a" and "b" is located and the content area where the dot "●" is located between "y" and "z" Region is the "fuzzy" input region. For example, in Figure 15d, when the user releases it at the original place, its content area can represent any character in "a", "b", and "c"; in Figure 15e, when the user releases it at the original place, Its content area can represent any character among "w", "x", "y", and "z". At this time, the keyboard will automatically find possible words from the dictionary according to the preceding and following characters input by the user, and prompt the user for confirmation.

More importantly, this input method can realize fuzzy and precise alternate input, thereby reducing the repetition rate, and at the same time better supports the input of custom words.

For example, when the user wants to input the word "pay", he can first input "p" precisely (press the focus area 7, move left to the content area "p" and release it), and then input "a" precisely (press the focus area 2. Move left to the content area "a" and release it), and finally enter "wxyz" in a blur (press the focus area 9 and release it directly). In this way, the word "pay" directly appears in the candidate box, as shown in Fig. 16a for details.

See again as shown in Figure 16b, if the user wants to input a custom word "iPod", he can first input "i" precisely (press the focus area 4, move right to the content area "i" and release it), and then input accurately "P" (press the focus area 7, move to the upper left content area "P" and release it), then input "o" precisely (press the focus area 6, move to the upper right content area "o"), and finally precisely Enter "d" (press focus area 3, move to upper left content area "d"). This way, the custom word "iPod" appears inside the candidate box. Users only need to click on the word to enter it and add it to thesaurus.

The content area associated with the focus area 1 is numbers from 0 to 9 and common symbols. When the user presses the focus area 1 (that is, the "number" key), the keyboard enters the content selection mode, and the layout of the associated content area is dynamically adjusted, as shown in FIG. 17 . After the user moves the touch point to a certain content area and releases it, the user can input the characters corresponding to the content area. In this embodiment, the content area associated with the focus area 1 does not need to be displayed in the initial keyboard layout, but only "number" is used to remind the user of its corresponding content area.

Adopt the above-mentioned method for realizing intelligent software keyboard input on the screen of an electronic device, because it divides the keyboard area into several focus areas and several content areas, and there is an association relationship between the focus area and the content area, that is, a focus area and a number of content areas Several content areas are associated, so the keyboard is divided into two working modes: focus selection mode and content selection mode; before the user touches the screen, the keyboard is in the focus selection mode, and the moment the user touches the screen, the keyboard senses the user's touch screen point In the focus area, dynamically switch the keyboard mode to the content selection mode, rearrange the content area associated with the focus area and enlarge the display, and the user can move and select between the content areas after the dynamic layout by moving the position of the touch screen ;Once the screen contact is separated from the keyboard surface, that is, the user lifts the touch point, the keyboard senses the content area where the user lifts the point, and uses the content of the content area as input. At the same time, the keyboard is switched back to the focus selection mode, which can be convenient and accurate The information input of the touch screen electronic equipment is not only simple in implementation process, but also convenient and quick to use, flexible and changeable; and the method of the present invention will make the user press the position of the touch point (focus area) and release the position of the touch point (content area) ) are combined into input information at the same time, so that the characters that can be input by the electronic device within the same keyboard range are greatly increased, and the fault tolerance is greatly enhanced. At the same time, the working performance is stable and reliable, and the scope of application is relatively wide.

In this specification, the invention has been described with reference to specific embodiments thereof. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
