Problems solved by technology

During the user's sliding input process, the user does not perform horizontal and vertical sliding input, and often the final input result is not the user's target input due to the wrong sliding direction. The gliding track is longer, but according to the rules of Chinese pinyin arrangement, the latter pinyin letter cannot follow the previous pinyin letter, which makes the latter pinyin letter not put into the target input result although the gliding track is longer, which leads to The existing taxi trajectory-based recognition rate is low and the input efficiency is low

Embodiment 1

[0054] This embodiment takes inputting Chinese pinyin as an example to complete the input of Chinese characters. In actual use, of course, various characters such as pinyin letters and English letters can also be input, as long as there are various characters in a predetermined sequence or characters of coded combinations. The input object is not specifically limited.

[0055] According to the rules of Chinese Pinyin, that is, according to the official Chinese Pinyin scheme, the character set that can follow other Pinyin (such as initials or other letters) in Pinyin is {a,e,g,h,i,m,n ,o,r,u,ü}, where ü is represented by v in the computer. During specific implementation, this character set can be adjusted according to the required character set, or all Chinese pinyin letters can be used as the character set. For example, m as a non-initial letter of pinyin will only follow h, and the Chinese characters corresponding to hm are rare and not commonly used, so m can not be added t...

Embodiment 2

[0082] like Figure 8 As shown, Embodiment 1 uses Chinese Pinyin letters or English Pinyin letters as characters for sliding input. The difference from Embodiment 1 is that this embodiment uses strokes as characters for sliding input. Of course, other characters can also be used for input. . Using Chinese strokes as characters for sliding input, Chinese strokes can be divided into several strokes, only need to use Chinese strokes as a character set, and establish the association between each Chinese stroke and direction. For example, Chinese font codes are divided into five stroke classes according to the regulations of the national official "Modern Chinese General Character List", and can certainly be divided into other strokes according to other rules, such as being divided into eight according to "Yongzi Bafa". In this example, if Figure 8 As shown, the Chinese strokes are divided into five strokes including dot, horizontal, vertical, fold, and apostrophe, plus a wildcar...

Embodiment 3

[0084] like Figure 9 As shown, the difference from Embodiment 1 is that the length of the curve segment of the taxiing track in Embodiment 1 does not consider the minimum length, that is, the length of the curve segment of the identified curve segment recognizes the corresponding character regardless of the length. In addition, Embodiment 1 sets The characters in the character set refer to characters that can be legal characters, such as Chinese pinyin, English letters, Chinese strokes, etc., but do not include special characters such as numbers, symbols, and functional operators. These special characters cannot Characters that form legal characters. In order to be able to input these special characters, in this embodiment, special characters are added to the character set, and special characters are associated with fixed directions one by one, Figure 9 Including the addition of the "delete" function operator and the "word selection" function operator, the "word selection" ...

Abstract

The invention relates to an input method based on sliding track recognition and a processing terminal. The input method comprises the following steps: obtaining a character set, dividing the characterset into a plurality of groups of sub-character sets, establishing a one-to-one mapping relation between the sub-character sets and directions, and establishing a one-to-one mapping relation betweenthe sub-character sets and a slope range. The method comprises the following steps: receiving an initial position signal of a user; receiving a sliding signal input by a user by taking the initial position as a starting point to obtain a sliding track; performing operation to obtain all legal combined characters; calculating the curve length of each curve segment; and calculating the track effective rate of each legal combined character, taking the legal combined character corresponding to the maximum track effective rate as an input character, and finishing input. The target characters needing to be input are obtained according to the track efficiency, the track length of sliding input of each character does not need to be limited, the recognition accuracy of sliding input is obviously improved, the use difficulty of a user is reduced, and the fault tolerance is better.

Description

technical field [0001] The invention relates to the technical field of sliding input methods, in particular to an input method based on sliding track recognition and a processing terminal. Background technique [0002] At present, many electronic devices such as handheld computers and smart phones use sliding input on the touch screen, and many commonly used character inputs (such as input method programs on smart phones) are input by sliding. During the user's sliding input process, the user does not perform horizontal and vertical sliding input, and often the final input result is not the user's target input due to the wrong sliding direction. The gliding track is longer, but according to the rules of Chinese pinyin arrangement, the latter pinyin letter cannot follow the previous pinyin letter, which makes the latter pinyin letter not put into the target input result although the gliding track is longer, which leads to The existing taxi trajectory-based recognition rate i...
