Description

A Chinese character input method based on a numeric keypad device

Technical field:

The invention relates to a Chinese character input method based on a numeric keypad device, which belongs to the field of computer Chinese information processing.

Background technique:

At present, the development and research of computer Chinese character coding input methods at home and abroad have entered a relatively mature stage. Most of the main methods use large computer keyboards as coding tuples, and are divided into phonetic codes designed based on Chinese character pronunciation rules and Chinese character Shape codes designed with structural rules, such as intelligent ABC and Wubi font input methods, etc., these input methods have played a good supporting role for the application of computer Chinese character information processing.

With the development of modern science and technology, especially computer technology and information technology, Chinese character processing technology has developed into a wider field, and has penetrated into communication equipment (such as mobile phones, telephones, etc.), handheld computers and electronic notepads, household appliances (such as TV, VCD, etc.), digital communication, Chinese character classification and retrieval and other application fields. Since the equipment involved in these applications has the characteristics of small size and convenient operation, it is impossible to have more key arrangements. How to effectively overcome the difficulties of Chinese character input , is a problem that needs to be solved at home and abroad.

The application equipment stated above all has a standard numeric keypad, so designing a standardized, simple and easy-to-learn Chinese character digital input method is a problem that most manufacturers need to solve urgently. At present, these equipment generally adopt stroke input methods and pinyin input methods. Since the average stroke of a Chinese character is 8 strokes, to complete the input of a Chinese character, the stroke input method must complete a Chinese character in a standardized manner, which is not only slow, but also difficult for ordinary people to accept; the pinyin input method corresponds to 3-4 on each number key English letters, and then input according to the full spelling of Chinese characters, the speed is even more unacceptable, and the accuracy rate is also low. Some digital devices provide a handwriting input function, but it is still difficult to solve the problems of speed and accuracy.

With the development of computer information processing technology (especially Internet technology), the amount of input of Chinese character information on digital devices is increasing day by day. Research on simple, easy-to-learn and fast Chinese character digital encoding method has great application prospects and practical significance.

After searching the patent literature, there is no public report identical with the present invention.

Invention content:

The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a kind of code element of each Chinese character encoding only relevant to the stroke classification sequence of each stroke pair combination, and a kind of based on numeral that has nothing to do with the concrete position of each numeral on the keyboard. Chinese character input method for small keyboard devices.

According to the natural structure of Chinese characters, the present invention divides Chinese characters into four structures: four-block characters, three-block characters, two-block characters, and single-block characters. Three types, get the first two strokes that constitute each block of Chinese characters according to the above stroke classification, and correspond to the key position distribution of the numeric keypad to form a 3 * 3 two-dimensional coordinate code (see attached drawing); the font is divided into There are 9 types of single characters, mostly surrounded, half surrounded, generalized left and right, left and right, left middle right, generalized upper and lower, upper and lower, upper middle and lower (among them: the outer surrounding range of mostly surrounded is greater than or equal to three quarters, such as encircled , Kuang, etc.; semi-enclosed outer encirclement range is one-half, such as hall, this, etc.; in a broad sense, left and right are left and right fonts, and the left and right parts can be further split at least; in a broad sense, up and down are upper and lower fonts, of which The upper side and the lower side part can be further split at least), corresponding to numbers 1-9 (see accompanying drawing) respectively.

The maximum code length of the present invention is 5 yards, and wherein the single block word carries out code fetching in pairs according to the total number of strokes of Chinese characters, and what is less than 5 yards is filled with numeral 0 in the middle of stroke combination coding and font code.

Concrete input method and keyboard arrangement of the present invention are:

1, four blocks of characters: (the first stroke of the first block, the second stroke) (the first stroke of the second block, the second stroke) (the first stroke of the third block, the second stroke) (the first stroke of the fourth block, the second stroke) font code;

2, three blocks of characters: (the first stroke of the first block, the second stroke) (the first stroke of the second block, the second stroke) (the first stroke of the third block, the second stroke) (the last stroke of the first block, the third word block last pen) font code;

3, two blocks of characters: (the first stroke of the first block, the second stroke) (the first stroke of the second block, the second stroke) (the first stroke of the first block, the first stroke of the second block) (the last stroke of the first block , the last pen of the second block) font code;

4. Single block characters:

(1) One and two strokes: (first stroke, last stroke) 000 font code;

(2) Three or four strokes: (the first stroke, the second stroke) (the third stroke, the last stroke) 00 font code

(3) five or six strokes: (the first stroke, the second stroke) (the third stroke, the fourth stroke) (the fifth stroke, the last stroke) 0 font code

(4) Characters with seven strokes and above: (first stroke, second stroke) (third stroke, fourth stroke) (fifth stroke, sixth stroke) (seventh stroke, last stroke) font code

According to the above input method design and keyboard arrangement, it can be seen that the present invention, compared with similar digital code input methods, has the characteristics of standard splitting of Chinese characters, simplicity and intuition, short learning period of the coding method, small amount of memory, and the ability to realize blind typing, etc. , which can be applied in the following fields:

1, communication equipment: mobile phone, telephone set etc., existing mobile phone has simple address book function mostly, and the Chinese character input method used is stroke, pinyin etc. generally, and high-grade mobile phone has handwriting input function, but input method is not ideal (such as Stroke input needs to correspond to the digital codes one by one according to the stroke order of Chinese characters, and the speed is relatively slow; because the mobile phone only has a numeric keypad, a number corresponds to several letters, and the operation is more complicated; handwriting input is relatively slow due to the influence of recognition technology, etc.), the present invention technology can solve the above problems.

Traditional telephone only has sound communication and recording (recording telephone) function, developed country is devoting oneself to the development of videophone, as a kind of communication tool, telephone also should have the text record function when not receiving, the present invention can realize Telephone transcripts provide technical support.

2. Pocket PCs and electronic notepads: The progress of science and technology has made computers develop in the direction of miniaturization. As representative products, handheld computers and electronic notepads are a field that is currently being vigorously developed. The sales of notepads are increasing several times every year, but such products are limited by the surface area, and most of them only have a numeric keypad and a small amount of auxiliary keys. If a simple and convenient digital coding method can be provided, it will promote the development of this field.

3. Household appliances such as TVs and VCDs: With the development of computer networks, IP TVs and network VCDs are emerging. This type of equipment mainly has functions such as playback, retrieval, browsing, and short message sending and receiving. and auxiliary keys) for Chinese character information input, and an excellent digital input coding method will play an active role.

4. Digital communication: At present, most communications are transmitted by analog signals (such as ordinary telephones). The development of science and technology will gradually replace analog signals with digital signals. The country is undergoing reconstruction projects in this area, such as IP telephones and cable television networks. etc. In my country's information communication, Chinese character information processing and communication are the main technologies to be solved, and Chinese character digital code input technology is an important aspect to realize the above goals.

5. Character classification and retrieval: There are thousands of commonly used Chinese characters in China. In the specific application of Chinese characters, the classification and retrieval of Chinese characters (such as dictionaries, etc.) is a systematic project. How does this work compare with modern Adapting to the development of science and technology, combining the traditional research of Chinese characters with technological development is a problem that needs to be further solved. The present invention can effectively carry out the application of character classification and retrieval.
