Background
A common interactive input mode for touch screen devices (such as mobile phones, tablet computers, conference machines, electronic blackboards, and the like) is a virtual keyboard, where a touch design of a general virtual keyboard is to allocate a fixed touch area (as shown in fig. 2) to each key according to a virtual keyboard UI (User Interface, Interface design) setting area (i.e., a display area of a key displayed on a display screen, as shown in fig. 1), and the touch area of each key is larger than the display area of each key displayed on the display screen. When a user executes touch operation in a designated area on a touch screen, if the area touched by the user is in the virtual keyboard, the touch program acquires touch coordinates of the user in the virtual keyboard area, and if the touch coordinates are in the touch area of a certain key, a touch event of the key is triggered, so that the touch operation of the key is realized. However, the touch area of each key is allocated based on the UI setting area of the virtual keyboard in a unified manner, and thus the method is not suitable for different touch habits of different users, and is poor in user experience.

The operation habit of the user can be fully embodied by the deletion frequency corresponding to the current touch position of the user, so that the frequency of clicking the deletion key by the user corresponding to the touch coordinate is exponentially increased by setting the preset value, the change of the value of each weighted value is increased, and the touch area is convenient to adjust.
With reference to the technical solution provided by the first aspect, in some possible implementation manners, before the obtaining the touch coordinate and the current weight value of each first key on the virtual keyboard adjacent to the touch coordinate, the method further includes: determining a weight value of the touch coordinate and each first key adjacent to the touch coordinate on the virtual keyboard based on a center line between the adjacent first keys and a position relation between the touch coordinate and the center line.

It should be noted that the dynamic adjustment method for the touch area of the key provided in the embodiment of the present application is not limited to the sequence shown in fig. 4 and the following. The method comprises the following steps: step S101-step S103.

That is, the embodiment of the present application realizes learning the touch control habit of the user based on the delete operation of the user, and then adjusts the touch control area of the key.
The above method is described in detail with reference to specific examples.
Step S101: and after the deletion operation corresponding to the deletion key is triggered, acquiring a touch coordinate corresponding to a touch position clicked on the virtual keyboard by a user at the moment before the deletion key is clicked.
The touch control habit learning method and device are mainly based on the user deleting operation to learn the touch control habit of the user. It can be understood that, when the user touches the virtual keyboard, for example, the touch position of the user is located at a point a between the key 1 and the key 2 (as shown in fig. 5), and the point a is located in the touch area of the key 1. When the touch position of the user is a, the number displayed on the display screen of the user is 1. If the user does not execute the deleting operation, it indicates that the number 1 is the one that the user wants to select currently, and if the user executes the deleting operation, it indicates that the number 1 may not be the one that the user actually wants to select. For example, the user's operation habit is to like the upper left corner of the touch key, and although the touch position a of the user falls into the touch area of the key 1, the user actually wants to go to the touch key 2. Therefore, the touch habit of the user can be learned based on the deleting operation of the user.
That is, in the embodiment of the present application, the first step is to obtain the touch coordinate corresponding to the touch position clicked on the virtual keyboard by the user at the previous moment when the delete key is clicked after the delete operation corresponding to the delete key is triggered.
Wherein the previous time may be understood as the previous time. That is, obtaining the touch coordinate corresponding to the touch position clicked on the virtual keyboard at the time before the user clicks the delete key may be understood as obtaining the touch coordinate of the touch position clicked on the virtual keyboard one time before the user clicks the delete key. For example, after the user touches the point a, the user clicks the delete key, where a is the touch position clicked on the virtual keyboard at the time before the user clicks the delete key, and the coordinate of a is the touch coordinate corresponding to the touch position clicked on the virtual keyboard at the time before the user clicks the delete key.
Step S102: according to a weight distribution rule, the touch coordinate and the weight value of each first key adjacent to the touch coordinate on the virtual keyboard are adjusted, so that the value of the highest weight value between the touch coordinate and the first key is reduced; wherein the weight value represents an association between the touch coordinate and the first key.
After the touch coordinate is obtained, the touch coordinate and the weight value of each first key adjacent to the touch coordinate around the touch coordinate are adjusted according to a weight distribution rule.
It can be understood that the weight value represents the association between the touch coordinate and the key. The larger the weight value between the touch coordinate and the key is, the greater the relevance between the touch coordinate and the key is, and the touch coordinate is allocated to the touch area of the key. That is, the touch area is determined according to each touch coordinate and the key with the largest weight value.
First, it should be noted that, in the initial state of the virtual keyboard, the touch coordinate and the weight value of each adjacent key are determined based on a central line between the adjacent keys and a position relationship between the touch coordinate and the central line. That is, the point on the center line is used as the dividing point to distribute the weight, the adjacent area of the two keys is 50%, the adjacent area of the three keys is respectively distributed with 33.3%, and the adjacent area of the four keys is respectively distributed with 25%. For example, with continued reference to fig. 5, for example, the weighted value between the point B on the center line between the key 1 and the key 2 and the key 1 and the key 2 is 50%. For another example, the weight values between the intersection C of the central lines between the keys 1, 2, 3, and 4 and the keys 1, 2, 3, and 4 are all 25%. And then determining the touch coordinate and the weight value of each adjacent first key based on the position relation between the central line and the touch coordinate. For example, if the distance between the key 1 and the key 2 is ten coordinate points, the distance between the middle line and the key 1 and the key 2 is five coordinate points, and the point on the middle line and the weight value between the key 1 and the key 2 are 50%, assuming that the distance between the point a in fig. 5 and the middle line is two coordinate points, the point a is located on the left side of the middle line, i.e., on the side close to the key 1, it may be determined that the weight value between the point a and the middle line is 70% based on the distance between the point a and the middle line and the point a is located on the left side of the middle line, and accordingly, the weight value between the point a and the key 2 is 1-70% — 30%. That is, the weight value of each touch coordinate and each connected first key is determined directly according to a linear distribution mode. Similarly, the weight values between each point located in the dashed line frame and the four keys can be determined based on that the weight values between the point C and the keys 1, 2, 3 and 4 are all 25% according to a linear distribution mode.
In the embodiment of the application, the touch coordinate and the current weight value of the second key are reduced by the preset value, and the reduced weight values are averagely distributed to the touch coordinate and the weight values of other first keys except the second key, so that the reasonable distribution of the weight values is realized.
Of course, in other embodiments, the weight value of each touch coordinate and each key connected to the touch coordinate may be determined based on a curve distribution manner. That is, the longer the distance between the touch coordinate point and the central line is, the larger the weight value changes, rather than linearly changing. For example, the distance between the point a and the central line is two coordinate points, the point a is located on the left side of the central line, and the weight value between the point a and the key 1 is 70%. However, by adopting the curve distribution method, the weight values of the point a and the key 1 may be 75%, 80%, and the like, and the application is not limited.
The weight distribution of each touch coordinate may be a weight distribution graph as shown in fig. 6. Each touch coordinate is adjacent to at most 4 keys and at least one key. Thus, 22 in fig. 6 indicates that such touch coordinates are adjacent to four keys (two above, two below). W (1) represents the weight value of the key at the upper left corner, W (2) represents the weight value of the key at the upper right corner, W (3) represents the weight value of the key at the lower left corner, and W (4) represents the weight value of the key at the lower right corner. 1 in fig. 6 indicates that such touch coordinates are adjacent to 1 key, and the weight value of such touch coordinates and the adjacent key is 100%. NA in fig. 6 indicates no other weight value. Fig. 6 shows that 11 indicates that such touch coordinates are adjacent to the upper and lower keys, W (5) indicates the weight value of the upper key, and W (6) indicates the weight value of the lower key. 110 in fig. 6 indicates that such touch coordinates are adjacent to the left and right keys, W (7) indicates the weight value of the left key, and W (8) indicates the weight value of the right key. The 12 in the figure indicates that there is an adjacent key above and two adjacent keys below the touch coordinate. W (9) represents the weight value with the upper key, W (10) represents the weight value with the lower left key, and W (11) represents the weight value with the lower right key. Fig. 6 at 21 indicates that there are two adjacent keys above and one adjacent key below such touch coordinates. W (12) represents a weight value with respect to the key at the upper left corner, W (13) represents a weight value with respect to the key at the upper right corner, and W (14) represents a weight value with respect to the key below.
Optionally, the weight distribution rule specifically includes: acquiring a touch coordinate and a current weight value of each first key adjacent to the touch coordinate on the virtual keyboard; reducing the touch coordinate and the current weight value of the second key by a preset value, and averagely distributing the reduced weight values to the touch coordinate and the weight values of other first keys except the second key; the second key is the key with the highest weight value between the first key and the touch coordinate.
That is, after the touch coordinate and the current weight value of each first key adjacent to the touch coordinate on the virtual keyboard are determined in the above manner, a preset value is subtracted from the highest weight value, and the reduced weight values are averagely distributed to the weight values of other keys adjacent to the touch coordinate.
Wherein the allocation formula is:
wherein, in the formula (1), W (k)0T-1) represents the current weight value between the second key and the touch coordinate, W (k)0T) the weighted value after adjustment between the second key and the touch coordinate;
representing a preset value; in the formula (2), W (k)nT-1) represents the current weight value between the key N and the touch coordinate, and the value of N is 1-N; n represents the number of first keys adjacent to the touch coordinates; n is greater than or equal to 1 and less than or equal to 4; the key n is one of the first keys except the second key; w (k)nT) represents a weighted value after adjustment between the key n and the touch coordinate;
representing a preset value.
In addition, W (k)0T) and W (k)nAnd t) is kept varying between 0 and 1.
When W (k)0T) to zero, in equation (2)
The weight value of (k) is W (k)0T-1) to 0 to ensure W (k)nT) will not overflow (over 1). And W (k)0T) and W (k)nAnd the sum of t) equals 1.
Wherein the preset value
May be 0.01, 0.02, 0.1, 0.2, etc., and the present application is not limited thereto.
In the embodiment of the application, the touch coordinate and the current weight value of the second key are reduced by the preset value, and the reduced weight values are averagely distributed to the touch coordinate and the weight values of other first keys except the second key, so that the reasonable distribution of the weight values is realized.
Optionally, a preset value
And the times of clicking the deleting key by the user corresponding to the touch coordinate are exponentially increased. That is, a preset value is set according to the deletion frequency of the user at the current touch position
Increasing exponentially. Illustratively, the preset value
The initial value of (a) is 0.01, the base number is 2, and the number of times that the user deletes the current touch position value (e.g., the touch coordinate point a corresponding to the current touch position) is 3, then the preset value is obtained
Of course, the base number may be a numerical value such as 3 or 5, and the present application is not limited thereto.
It should be noted that, because the deletion frequency corresponding to the current touch position of the user can fully reflect the operation habit of the user, the number of times that the user clicks the deletion key corresponding to the touch coordinate is exponentially increased by setting the preset value, so that the value change of each weight value can be increased, and the touch area can be conveniently adjusted.
Optionally, in another embodiment, the weight distribution rule may further include: acquiring a touch coordinate and a current weight value of each first key adjacent to the touch coordinate on the virtual keyboard; and reducing the touch coordinate and the current weight value of the second key by a preset value, and distributing the reduced weight value to the weight value between the touch coordinate and the third key. The second key is the key with the highest weight value between the first key and the touch coordinate. The third key is a key with the second highest weight value between the first key and the touch coordinate.
That is, after the touch coordinate and the current weight value of each first key adjacent to the touch coordinate on the virtual keyboard are determined in the above manner, the highest weight value is subtracted by a reduced preset value, and the reduced weight value is assigned to the second highest weight value.
Of course, in other embodiments, the weight distribution rule may include: acquiring a touch coordinate and a current weight value of each first key adjacent to the touch coordinate on the virtual keyboard; reducing the touch coordinate and the current weight value of the second key by a preset value, and distributing the reduced weight value to the touch coordinate and the weight values of other first keys except the second key according to a preset proportion; the second key is the key with the highest weight value between the first key and the touch coordinate.
The preset ratio may be determined based on the touch coordinates and the weight values of the other first keys except the second key, for example, if the weight values of the touch coordinates and the key 2 are 20% and the weight values of the touch coordinates and the key 3 are 30%, the preset ratio may be 2:3, that is, the reduced weight values are allocated to the weight values of the touch coordinates and the key 2 and the weight values of the touch coordinates and the key 3 according to the ratio of 2: 3.
Therefore, in the specific process of adjusting the weight, which weight distribution rule is specifically selected is not limited in the present application.
According to the method for dynamically adjusting the touch areas of the keys, the touch areas of the keys are adjusted, and the actual display areas of the keys are unchanged, so that a user uses a virtual keyboard to have many errors due to the fact that the touch areas are not matched with the display areas after the touch areas are adjusted, and the touch areas of the keys are preset with safe touch areas. As shown in fig. 7, the area corresponding to the middle dashed box of each key is a safe touch area. The safe touch area represents an area where no adjustment is performed. And when the virtual keyboard is in an initial state, each touch coordinate in the self-adaptive area generates a touch area of each key based on the touch coordinate and the weight value of each adjacent key. That is, in fig. 7, the touch coordinate a point is located at the touch area of the key 1, and the weight value of the key 1 is the highest.
Accordingly, before step S102, the method further includes: determining that the touch coordinates are not within the safe touch area.
That is, only when the touch coordinate is not located in the safe touch area, the touch coordinate and the weight value of each first key adjacent to the touch coordinate on the virtual keyboard are adjusted. And if the touch coordinate is in the safe area, no adjustment is performed.
Step S103: and adjusting the touch area of each first key based on the touch coordinates and the adjusted weight value of each first key, so that the touch coordinates are located in the touch area of the first key corresponding to the adjusted highest weight value.
After the touch coordinate and the weight value of the adjacent first key are adjusted, the touch area of each first key is adjusted based on the adjusted weight value. And adjusting the touch area to which the touch coordinate belongs by using the highest weight value, namely, distributing the touch coordinate to the touch area of the first key with the highest weight value.
By the above method, the touch area of the entire virtual key can be adjusted, and the adjusted touch area of the virtual key can refer to fig. 8. As can be seen from fig. 8, the touch areas of the keys are different, and the touch area of each key is adjusted according to the operation habit of the user.
Optionally, after the touch area of the virtual keyboard is adjusted, the method further includes: saving the virtual keyboard corresponding to the adjusted touch area in a database; wherein the database is associated with an account of the user; and after receiving a click instruction of a user for clicking the input box, calling a virtual keyboard from a database associated with the account of the user, and displaying the virtual keyboard.
