detailed description

The invention may be illustrated by the following examples. However, the embodiments of the present invention are not intended to limit the present invention to be implemented in any specific environment, application or manner as described in the embodiments. Therefore, the descriptions of these embodiments are only for the purpose of illustrating the present invention, rather than directly limiting the present invention. In the following embodiments and drawings, elements not directly related to the present invention have been omitted and not shown; and the dimensional relationship among the elements in the drawings is only for easy understanding, not to limit the actual ratio.

A first embodiment of the present invention is shown in FIG. 1 , which shows a portable device 1 . As shown in FIG. 1 , the portable device 1 can be a mobile phone, which includes a touch screen 11 and a processor 13 coupled to the touch screen 11 . In other embodiments, the portable device 1 can also be a notebook computer, a tablet computer, a personal digital assistant (PDA) and the like. Optionally, in other embodiments, the portable device 1 may also include a memory module coupled to the processor 13 for storing data.

For example, the touch screen 11 can be a capacitive touch screen, a resistive touch screen, a resistive-capacitive composite touch screen, an electromagnetic induction touch screen, and the like. As shown in FIG. 2 , the touch screen 11 is used to display an input method editor (input methodeditor; IME) 111 including a plurality of virtual keys 2, and these virtual keys 2 may include a plurality of character keys 20 and a plurality of functions Key 22, and other keys of different categories. It should be noted that the shape of the input method editor 111 and the configuration of the virtual keys 2 are only for the purpose of illustrating the present invention, rather than limiting the present invention.

As shown in FIG. 3A , each of the virtual buttons 2 has its own button click range 4 , and the button click range 4 covers a specific rectangular area corresponding to its shape. In other embodiments, the button click range 4 of each virtual button 2 may also cover a specific circular area, and the center of the circular area is located at the center of the corresponding virtual button 2 . As another option, the button click range 4 of each virtual button 2 may also cover an area corresponding to other shapes (such as hexagon, octagon, polygon, etc.).

In the following, it will be explained how the portable device 1 detects an input event 12 triggered through the input method editor 111 and adjusts the key click range 4 of the virtual key 2 in response to the input event 12 . In this embodiment, the input event 12 means that a user intends to input a word through the input method editor 111 displayed on the touch screen 11 . Therefore, the processor 13 will be used to detect the input of a word and adjust the key click range 4 of the virtual key 2 accordingly.

First, the processor 13 is used to determine whether at least one character input through the character key 20 has formed a word. Specifically, the processor 13 can detect the current character input through the character key 20 and determine whether the combination of the current character and its previous character has formed a word. If the at least one character has not yet formed a word, the processor determines that the next input is still a character input rather than a function input. Therefore, as shown in FIG. 3B, the processor 13 enlarges the key click range 4 of the character key 20 and narrows the key click range 4 of the function key 22, so that the user can input the next character of the word more easily.

Otherwise, as shown in FIG. 3C , if the at least one character has formed a word, the processor 13 can enlarge the key click range 4 of the function key 22 and reduce the key click range 4 of the character key 20 . However, a complete word may consist of more than one word or a word and other characters. For example, the complete word "keyboard" is composed of the word "key" and the word "board", and another complete word "viewer" is composed of the word "view" and the characters "e" and "r".

Therefore, when the at least one character has formed a word, the processor 13 can pre-determine whether the word is complete before adjusting the key click range 4 of the virtual key 2 . In other words, after the processor 13 judges that the word is a complete word, it will enlarge the key click range 4 of the function keys 22 and reduce the key click range 4 of the character keys 20 . Thereby, it can be avoided that the next input may be a character, but the button click range 4 of the function button 22 has been enlarged and the button click range 4 of the character button 20 has been reduced.

The processor 13 may include a candidate word engine (not shown in the figure) to generate candidate word information, thereby enhancing the convenience of input. Specifically, the processor 13 can predict the next character according to the input character and provide candidate word information to the user accordingly. Based on the candidate word information, the processor 13 can determine whether the word is complete. It should be noted that the processor 13 can also determine whether the word is complete by other methods known to those skilled in the art, and the description here is not intended to limit the implementation of the present invention.

If the processor 13 determines that the word is incomplete, it implies that the next input should be a character input rather than a function input. As mentioned above, the processor 13 may further predict a predicted character after the word according to the candidate word information. Then, the processor 13 further determines whether the character key 20 corresponding to the predicted character is arranged adjacent to any one of the function keys 22 .

If the character key 20 corresponding to the predicted character is not set adjacent to any one of the function keys 22, the processor 13 enlarges the key click range 4 of the character key 20 and narrows the key click range 4 of the function key 22, as Figure 3B. Otherwise, if the character key 20 corresponding to the predicted character is set adjacent to any one of the function keys 22, the processor 13 can restore the key click range 4 of the character key 20 and the key click range 4 of the function key 22, As shown in Figure 3A.

The following is an example to further illustrate this embodiment. It should be noted that the following examples are only for the purpose of illustrating the present invention, rather than limiting the present invention. This example will be based on the following condition: a user wants to input the word "DUCK" via the input method editor 111 .

After detecting the first character "D" input via the input method editor 111, the processor 13 determines that the first character "D" has not yet formed a word, so the processor 13 enlarges the key click range 4 of the character key 20 and narrows down the function The button click range 4 of the button 22 is shown in FIG. 3B .

Then, after detecting the second character "U" and the third character "C", the processor 13 judges that both the character combination "DU" and "DUC" have not yet formed a word, so the processor 13 still enlarges the character button 20 The button click range 4 of the function button 22 is narrowed down, as shown in FIG. 3B . Then, after detecting the fourth character "K", the processor 13 determines that the character combination "DUCK" has formed a word (that is, the word "DUCK"), and then the processor 13 can further determine whether the word is based on the candidate word information. whole.

If it is determined that the word "DUCK" is complete, the processor 13 enlarges the key click range 4 of the function keys 22 and reduces the key click range 4 of the character keys 20, as shown in FIG. 3C . If it is determined that the word "DUCK" is incomplete, the processor 13 further determines whether the character key 20 corresponding to a predicted character after the word is set adjacent to any one of the function keys 22 .

For example, the candidate word information implies that the complete word input via the input method editor 111 is the word "DUCKBILL". In this way, the processor 13 determines that the predicted character after the word "DUCK" is "B", and then determines that the character key 20 corresponding to the predicted character "B" is adjacent to at least two of the function keys 22 (that is, the function key "space (space) )” and the function button “circle (circle)”). Then, the processor 13 restores the key click range 4 of the character key 20 and the key click range 4 of the function key 22 , as shown in FIG. 3A .

Furthermore, if the candidate word information implies that the complete word input via the input method editor 111 is the word "DUCKER". The processor 13 determines that the predicted character after the word "DUCK" is "E", and further determines that the character key 20 corresponding to the predicted character "E" is not adjacent to any one of the function keys 22 . Therefore, the processor 13 still enlarges the key click range 4 of the character keys 20 and narrows the key click range 4 of the function keys 22 , as shown in FIG. 3B .

Based on the shape of the input method editor 111 and the layout of the virtual keys 2, once it is determined that the predicted characters after a word are characters "A", "Z", "X", "C", "V", "B", " One of N", "M" and "L", the processor 13 restores the button click range 4 of the character button 20 and the button click range 4 of the function button 22, as shown in FIG. 3A. Otherwise, the processor 13 enlarges the key click range 4 of the character key 20 and reduces the key click range 4 of the function key 22 , as shown in FIG. 3B .

A second embodiment of the present invention can be regarded as the portable device 1 described in the first embodiment. Accordingly, for the same elements as those of the first embodiment, the same reference numerals will be used. For the omitted description, reference may be made to the foregoing embodiments, so details are not repeated here.

Hereinafter, differences between the first embodiment and the second embodiment will be described. In the second embodiment, the input event 12 refers to a user inputting some correct content through the input method editor 111 displayed on the touch screen 11 . The processor 13 is used to detect the touch position corresponding to these correct contents and adjust the key click range 4 of the virtual key 2 accordingly.

Actually, whenever a user intends to touch one of the virtual keys 2 for input, the touched positions corresponding to each virtual key 2 are not always the same. On the contrary, these touch positions are distributed in the button click range 4 of the virtual button 2 . Therefore, the processor 13 is used to detect and collect all touch positions within the key click range 4 of the virtual key 2 .

Specifically, whenever the processor 13 detects a touch position located in the key click range 4 of each virtual key 2, the processor 13 can record a two-dimensional coordinate (x, y) of the detected touch position ). The coordinates of the touch position can be stored in a memory module (not shown) coupled with the processor 13 . In this way, the processor 13 can obtain all the touched positions on each of the virtual keys 2 in response to the input event 12 . Then, the processor 13 calculates a touch deviation of each virtual key 2 according to the touch position 6 . Next, the processor 13 adjusts the button click range 4 of each virtual button 2 according to the corresponding touch deviation.

The adjustment of the character keys "Q" and "W" will be further described below with reference to FIG. 4 as an example. Assume that the button click range 4 of each virtual button 2 covers a specific circular area, and the center of the circular area is located at the center of the corresponding virtual button 2 . It should be noted that this example is only for the purpose of illustrating the present invention, not limiting the present invention.

As shown in FIG. 4 , if the user has touched a plurality of touch positions 6 in the button click range 4 of the character keys "Q" and "W", and the processor 13 has detected and recorded these touch positions 6 . The processor 13 can calculate a touch deviation of each of the character keys “Q” and “W” according to the corresponding touch positions 6 . The processor 13 can calculate these touch deviations by calculating various statistical data (such as average values, variables, etc.) of the touch positions 6 of the character keys “Q” and “W”.

In other embodiments, after the statistical data of the touch position 6 is calculated, a part of the touch position 6 with larger deviation may be discarded to obtain a more accurate touch deviation. It should be noted that the numbers of the touch positions 6 of the character keys “Q” and “W” shown in FIG. 4 are only for the purpose of explaining the present invention, not limiting the present invention.

In view of the distribution of touch positions 6 in the key click range 4 of the character key "Q", the processor 13 can determine that when the user intends to input the character "Q" via the input method editor 111, he will always touch the character Keystroke for key "Q" hits somewhere near the right side of range 4. Therefore, the processor 13 dynamically adjusts the key click range 4 of the character key “Q” toward the right side of the key click range 4 of the character key “Q”, as shown in FIG. 4 .

On the other hand, in view of the distribution of the touch positions 6 in the key click range 4 of the character key "W", the processor 13 can determine that when the user intends to input the character "W" via the input method editor 111, he always A key that will touch the character key “W” is clicked somewhere near the lower side of the range 4 . Therefore, the processor 13 dynamically adjusts the key click range 4 of the character key “W” toward the lower side of the key click range 4 of the character key “W”, as shown in FIG. 4 .

It should be noted that in other embodiments of the present invention, all operations described in the second embodiment can be combined with all operations described in the first embodiment and considered as a whole. Those skilled in the art can directly understand the method for the portable device 1 to perform these operations simultaneously based on the descriptions of these embodiments, so details are not repeated here.

A third embodiment of the present invention is the portable device 1 as described in the first embodiment. Accordingly, for the same elements as those of the first embodiment, the same reference numerals will be used. For the omitted description, reference may be made to the foregoing embodiments, so details are not repeated here.

Hereinafter, differences between the first embodiment and the third embodiment will be described. In the third embodiment, the input event 12 indicates that a user makes an erroneous input touch via the input method editor 111 displayed on the touch screen 11 . Therefore, the processor 13 is used to detect and analyze the wrong touch and adjust the button click range 4 of the virtual button 2 accordingly.

In practice, whenever a user wants to touch one of the virtual keys 2 for input, he may not touch the correct virtual key 2 . Instead, he may touch another virtual key 2 adjacent to the correct virtual key 2 . Therefore, the processor 13 is used to detect and analyze the wrong touch and adjust the button click range 4 of the virtual button 2 accordingly.

In the following, two different applications will be described as examples. In the first application, the processor 13 obtains a word input via the input method editor 111 in response to the input event 12 . Next, the processor 13 predicts a reference word corresponding to the word. The processor 13 can predict the reference word according to the candidate word information. Then, the processor 13 compares the word with the reference word to determine whether a first character of the word is different from a second character of the reference word at the same character position.

If at the same character position, the character of the word is different from the second character of the reference word, then the processor 13 judges the virtual key 2 corresponding to the first character because the first character is different from the second character Whether it is set adjacent to the virtual key 2 corresponding to the second character. If the virtual key 2 corresponding to the first character is set adjacent to the virtual key 2 corresponding to the second character, it implies that the user has actually entered the first character by mistake. On the contrary, the first character of the word is only different from the second character of the reference word, rather than a wrong character entered by the user.

Once it is determined that the first character is wrong and the virtual key 2 corresponding to the first character is set adjacent to the virtual key 2 corresponding to the second character, the processor 13 will respond to the virtual key 2 corresponding to the first character. The key 2 is arranged to be adjacent to the virtual key 2 corresponding to the second character to adjust the key click range 4 of the virtual key 2 corresponding to the first character and the second character.

For example, a user intends to input the word "TEACHER" through the input method editor 111, but he inputs the wrong word "TEACHRR". This example will be further explained below with reference to FIG. 5 . As shown in FIG. 5 , the button click range 4 of each virtual button 2 covers a specific circular area, and the center of the circular area is located at the center of the corresponding virtual button 2 . It should be noted that this example is only for the purpose of illustrating the present invention, not limiting the present invention.

After detecting the wrong word "TEACHRR", the processor 13 predicts the word "TEACHER" according to the candidate word information as a reference word corresponding to the wrong word "TEACHRR". Next, the processor 13 compares the wrong word "TEACHRR" with the reference word "TEACHER", and the processor 13 determines that the wrong word "TEACHRR" and the reference word "TEACHER" have a different character at the penultimate character position. In other words, the penultimate character "R" of the erroneous word (ie, "TEACHRR") is different from the penultimate character "E" of the reference word (ie, "TEACHER").

After comparing the wrong word "TEACHRR" with the reference word "TEACHER", the processor 13 further determines that the virtual key 2 corresponding to the first character (that is, the penultimate character "R" of the wrong word "TEACHRR") is Arranged adjacent to the virtual key 2 corresponding to this second character (ie, referring to the penultimate character "E" of the word "TEACHER"). Therefore, the processor 13 determines that the user mistakenly input the penultimate character "R" of the wrong word "TEACHRR", and the correct character should be the character "E". This implies that the user may have touched a position within the key click range 4 of the character key “R” when intending to touch the character key “E”.

Accordingly, the processor 13 may shift the key click range 4 of the virtual key 2 corresponding to the second character (ie, the character “E”) toward the virtual key 2 corresponding to the first character (ie, the character “R”), And narrow down the key click range 4 of the virtual key 2 corresponding to the first character (ie, the character "R"), as shown in FIG. 5 .

In the second application, the processor 13 obtains a first character input via the input method editor 111 in response to the input event 12 . The processor 13 also obtains a second character input through the input method editor 111 and used to replace the first character in response to the input event 12 . Next, the processor 13 determines whether the virtual key 2 corresponding to the first character is set adjacent to the virtual key 2 corresponding to the second character. If the virtual key 2 corresponding to the first character is set adjacent to the virtual key 2 corresponding to the second character, the processor 13 adjusts the button clicks of the virtual key 2 corresponding to the first character and the second character Range 4.

For example, a user wants to input the word "TEACHER" through the input method editor 111, and he has input the character combination "TEACH". Then, the user mistakenly inputs the character "R" as the input of the character combination "TEACH", and then deletes the wrong character "R" and re-enters the correct character "E" to replace the wrong character "R". This example will also be described below with reference to FIG. 5 . It should be noted that this example is only for the purpose of illustrating the present invention, not limiting the present invention.

In this example, the processor 13 is used to obtain a first character input via the input method editor 111 (ie, the wrong character “R”), and then obtain a character input via the input method editor 111 to replace the first character. The second character of a character (ie, the correct character "E"). After acquiring the first character and the second character, the processor 13 further determines that the virtual key 2 corresponding to the first character is set adjacent to the virtual key 2 corresponding to the second character. This implies that the user touches a position in the key click range 4 of the character key “R” when he intends to touch the character key “E”.

Accordingly, the processor 13 may shift the key click range 4 of the virtual key 2 corresponding to the second character (ie, the character “E”) toward the virtual key 2 corresponding to the first character (ie, the character “R”), And narrow down the key click range 4 of the virtual key 2 corresponding to the first character (ie, the character "R"), as shown in FIG. 5 .

Those skilled in the art can directly understand the method for the portable device 1 to perform these operations simultaneously based on the descriptions of these embodiments, so details are not repeated here.
