Problems solved by technology

However, limited by the size of the touch screen, input errors occur from time to time
[0003] During the input process, most of the input errors are caused by a certain deviation between the user's touch area and the actual button area, and such errors cannot be effectively corrected according to the existing sound-type error correction methods
For example, the existing pinyin input method can obtain the optional term "neutralization" after correcting "zonghe"; but if the user misuses the "Z" key and clicks the "X" key by mistake, the input becomes "xhonghe", then the existing technical solutions cannot prompt the option word "neutralization"
When multiple characters in a string are misplaced at the same time, the existing technical solutions are more difficult to effectively correct errors

[0134] Figure 6 It is a flowchart of a character string input method in the fourth embodiment of the present invention. This embodiment provides a preferred method for calculating the first weight of an approximate character string based on the foregoing embodiments, such as Figure 6 As shown, the method includes:

[0135] 601. Sequentially read a replacement character in the approximate character string.

[0136] 602. Obtain a similarity weight of the replacement character relative to the corresponding input character.

[0137] 603. Use the product of the first weight and the above similarity value as a new first weight, where the first weight is initialized to 1.

[0138] 604. Determine whether the replacement character is the last replacement character in the approximate character string: if yes, go to 605; otherwise, go to 601.

[0139] 605. Return the calculated value of the first weight.

[0140] For example, the string zn is an approximate string of the input stri...

Abstract

The invention discloses a character string input method and a character string input device. The method comprises the following steps of: acquiring an input character corresponding to an input instruct; acquiring a substitute character corresponding to the input character; adding the input character into a current character string; acquiring the input character and the substitute character of the input character in the current character string; generating an approximate character string corresponding to the current character string; calculating a first weight value of the approximate character string; acquiring a second weight value of the approximate character string according to difference between the approximate character string and a standard character string in a word database; calculating a total weight value of the approximate character string; sequencing the approximate character string; and displaying the approximate character string according to a sequence result. According to the method and device, correct input character string can be still acquired from selectable character string options even due to clicking or contacting other keys around an expected key by mistake during character string input at a client.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a character string input method and input device. Background technique [0002] With the continuous development of mobile communication terminals, various portable electronic devices appear on the market, such as personal computers, mobile phones, and tablet computers. With the rapid development of touch screen technology, more and more electronic devices use virtual keyboards. However, limited by the size of the touch screen, input errors occur from time to time. [0003] During the input process, most of the input errors are caused by a certain deviation between the user's touch area and the actual button area, and such errors cannot be effectively corrected according to the existing sound-type error correction methods . For example, the existing pinyin input method can obtain the optional term "neutralization" after correcting "zonghe"; but if the user misuses the "Z...
