Problems solved by technology

This type of solution is represented by the existing pinyin input method on the touch screen. Its disadvantages are: the user needs to switch the virtual keyboard frequently, and needs to click the virtual keyboard key multiple times frequently, which not only increases the fatigue and complexity of the operation, but also reduces the user experience. input efficiency, which increases the error rate
This type of solution is represented by the technology disclosed in the patent document with application number 201010542968.9. Its disadvantages are: due to the unpredictability of the input, it is necessary to identify and select the follow-up content, thereby reducing the input speed, and it is necessary to stare at the touch screen for a long time. Cause eye fatigue and affect vision health
The disadvantages are: crowded button layout, high requirements for touch screen space and touch screen resolution, long gliding path, you must keep an eye on the keyboard to operate accurately, and require complex algorithms to track touch trajectories
[0007] In-depth analysis of the root cause of the low input efficiency and high error rate of the existing technology is: the number of click operations based on the touch screen is too frequent, or the path of the touch operation is unpredictable, and the touch track is too long
If you click too many times, it is easy to make a wrong click. The path of the swipe is unpredictable, so you must use the virtual keyboard or follow-up keyboard prompts. If the touch track is too long, it will cause fatigue in the operation and it is easy to be blocked by the swipe tool.

Embodiment 1

[0129] Specifically, the correspondence between the directional dot-and-dash symbols and the candidate set symbols is referred to as a directional-dot-and-dash symbol-candidate set symbol correspondence table. Such as Figure 5 As shown, Embodiment 1 of the directional dot-and-dash symbol-candidate set symbol correspondence table of the present invention: 52 kinds of directional dot-and-dash symbols based on an effective touch origin correspond to 26 lowercase letters and 26 uppercase letters respectively, and input the 52 52 kinds of English alphabet candidate set characters can be input respectively by using one kind of directional dot-and-dash symbols.

[0130] In particular, it should be noted that: Figure 5 The shown directional dot-and-dash symbol-candidate set symbol correspondence table is only an embodiment of the directional dot-and-dash symbol-candidate set symbol correspondence table of the present invention, and the specific 52 kinds of directional dot-and-dash ...

Embodiment 2

[0217] like Figure 20A Shown, according to the Chinese phonetic alphabet input method of a preferred embodiment of the present invention, comprises the following steps:

[0218] Step 2001, setting the touch screen to have only one logical input partition, without displaying the virtual keyboard, and performing the same operation based on any position of the touch screen can input the same pinyin or English letters;

[0219] Step 2002, optimize 49 kinds of directional dot-and-dash trajectories based on the directional dot-and-dash input technology described in the present invention and use different graphic symbols to express and assign values ​​with 49 two-digit Arabic numerals at the same time, and finally define 50 kinds of directional dot-and-dash symbols, including "·=01、↑=10、 →=30、 ↓=50、 ←=70, Long ↑=31, Long → = 33, Long↓=35、 Long ←=37,

[0220] Step 2003, setting the corresponding relationship of 49 kinds of directional dot-and-dash symbols and t...

Embodiment 3

[0229] like Figure 21 Shown, according to the Chinese 10-key phonetic alphabet input method of a preferred embodiment of the present invention, comprises the following steps:

[0230] Step 2101, set the touch screen as 10 logical input partitions, that is, set the virtual keyboard to include 10 key positions, and at most 10×52=520 candidate set characters can be input at the same time;

[0231] Step 2102, based on the directional dot-and-dash input technology of the present invention, 52 kinds of directional dot-and-dash trajectories are selected, and different graphic symbols are used to express and simultaneously assign values ​​with 52 two-digit Arabic numerals, which are finally defined as 52 kinds of directional dot-and-dash symbols, including "·=01, ¨=02, ...=03, ::=04, ↑=10, →=30、 ↓=50、 ←=70, Long ↑=31, Long → = 33, Long↓=35、 Long ←=37,

[0232] Since the present embodiment is provided with 10 virtual keyboard keys, such as image 3 As shown, in...

Abstract

The invention relates to an input method. Based on a directional dot-dash input technology, touch tracks of 52 directional dots and dashes are optimized and are respectively expressed by using 52 directional dot-dash symbols; 52 times of touch tracks are expressed by one or n logic input partitions based on a touch screen; meanwhile, the corresponding relation between each directional dot-dash symbol and various candidate set symbols (comprising character symbols and function symbols) is allowed to be freely set, the corresponding candidate set symbols can be outputted after specified directional dot-dash symbols are inputted. According to the input method disclosed by the invention, off-screen touch typing of touch screen input is realized for the first time, so that the accuracy of dot-dash input can be ensured and the diversification of input contents can be met; in addition, the input method has the advantages of simple algorithm, high response speed and low power consumption. Bases on a 10-key Pinyin input method disclosed by the invention, at most 520 symbols (including initial consonants and compound vowels of Pinyin, simplicity, Pinyin auxiliary codes, strokes of Chinese Characters, English letters, number, punctuation symbols and the like) can be simultaneously input without switching an interface; in addition, each kind of symbol at most slide for the length of two key positions.

Description

technical field [0001] The invention relates to the field of computer and information interaction technology processing, in particular to an input method and device based on a touch screen, a Chinese pinyin input method and a system. Background technique [0002] With the maturity of touch screen technology, portable intelligent mobile terminal equipment has been widely used, and human-computer interaction technology based on touch-sensitive devices has received unprecedented attention. The input and output of information based on touch screen has become the most important and most extensive in the field of computer and communication. application technology. [0003] The existing touch-screen-based input technology usually simulates a virtual keyboard on the touch screen, and uses point-and-click tools (including fingers, touch pens, trackballs, etc.) to click or slide on the virtual keyboard to input information. Due to the small size of the touch screen, the number of key...
