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

[0056] This embodiment takes the input of Chinese pinyin to complete the input of Chinese characters as an example. In actual use, of course, various characters such as pinyin letters and English letters can also be input, as long as they have various characters in a specified arrangement order or characters with a code combination. The input object is not specifically limited.

[0057] According to the Chinese pinyin arrangement law, that is, according to the official Chinese pinyin plan of the country, the character set that can follow other pinyins (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. In 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 very few and not commonly u...

Embodiment 2

[0084] Such as Picture 8 As shown, the first embodiment uses Chinese pinyin letters or English pinyin letters as characters for sliding input. The difference from the first embodiment is that this embodiment uses strokes as characters for sliding input. Of course, other character input can also be used. . Using Chinese strokes as characters for sliding input, the Chinese strokes can be divided into several strokes, just use the Chinese strokes as a character set, and establish the association between each Chinese stroke and the direction. For example, according to the national official "Modern Chinese Characters List", the Chinese shape codes are divided into five types of strokes. Of course, they can also be divided into other strokes according to other rules, such as eight types according to the "Eight Methods of Yongzi". In this embodiment, such as Picture 8 As shown, the Chinese strokes are divided into five strokes including dot, horizontal, vertical, fold, and skew, plu...

Embodiment 3

[0086] Such as Picture 9 As shown, the difference from the first embodiment is that the length of the curve segment of the sliding track in the first embodiment does not consider the minimum length, that is, the curve length of the recognized curve segment recognizes the corresponding character regardless of the length. In addition, the first embodiment sets The characters in the character set refer to the characters that can become legal characters, such as Chinese pinyin, English letters, Chinese strokes, etc., but excluding special characters such as numbers, symbols, and function operators. These special characters cannot Form the characters among the legal characters. In order to be able to input these special characters, in this embodiment, special characters are added to the character set, and the special characters are associated with a fixed direction one by one. Picture 9 Including the addition of the "delete" function operator and the "select word" function operator...

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 and processing terminal based on sliding track recognition. Background technique [0002] At present, many electronic devices such as PDAs and smart phones use sliding input on the touch screen, and many commonly used character input (such as input method programs on smart phones) are input by sliding. In the process of user sliding input, the user will not glide input horizontally and vertically, often because the sliding direction is wrong, the result of the last input is not the user's target input. At the same time, even if the sliding trajectory of the next pinyin letter is greater than the previous one The glide trajectory of is longer, but according to the Chinese pinyin arrangement rules, 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 glide t...
