Soft keyboard for touch screen input

Abstract

The soft keyboard for touch screen input completes input in the dash and dot mode and includes several input lattices, each of which includes one central area and four, upper, lower, right and left, peripheral areas, capable of being defined separately in input symbol. The said technological scheme has relatively more input key positions, raised input speed and comfort, as well as combined character selecting area and coding display and controlled mark number. In addition, the present invention may have the soft keyboard configured into different input keyboard capable of being switched with character selecting and code displaying functions.

Description

technical field [0001] The invention relates to a soft keyboard used for touch screen input, in particular to a Chinese and English keyboard arrangement scheme of the soft keyboard which uses a combination of dots and dashes for input. Background technique [0002] The touch screen is a technology widely used at present. For the touch screen, the input method is usually to display an analog keyboard on the touch screen, which is generally called a soft keyboard, and then input by clicking or moving after clicking. Since touch screens are generally small, especially those used in small electronic products, the rationality of the keyboard arrangement becomes an important factor affecting the input performance and efficiency of the soft keyboard. [0003] A current solution is to design a soft keyboard similar to the traditional 3*4 mechanical phone buttons, and input characters through the definition of button combinations. Press two keys to input a character, for example, pr...

Problems solved by technology

[0005] First of all, it is not suitable for inputting coded characters such as Chinese. Since there is no design such as character selection and display codes, there is no way to realize the input of Chinese pinyin and Wubi, and the input of Japanese and Chinese characters.

[0006] Second, the labeling method is unscientific. It just hashes the characters represented by each direction in each direction of the key position. There is no effective direction icon, which is not convenient for users to view

At the same time, there are too many labels on a key. In this technology, a key can be combined with eight surrounding keys besides itself, so a key can represent up to 9 characters, but they are all marked on the key by direct labeling. It is already difficult to see the 9 characters marked on the small keys, and it is even more difficult to see the display on the soft keyboard, which requires a higher resolution of the screen and is difficult to remember
