Problems solved by technology

Due to the limitation of the size of the touch screen, the key size of many touch screen keyboards is usually small, and the keyboard keys of the touch screen have no edge touch, and the user often misspells and touches the phenomenon during the input process, thus making the user's input speed and user experience both dropped sharply

Embodiment 1

[0026] Such as Figure 1 to Figure 5 As shown, this embodiment predicts the target letter that the user may input next based on the pinyin rules, and marks each letter on the keyboard with a weight, and finally adjusts the size and size of the target letter key without changing the original layout of the keyboard. Shorten its distance from the current key.

[0027] The prediction of the possible target letters based on the pinyin rules refers to: according to the Chinese pinyin rules, for any letter combination, all the letters that may appear after the current letter combination can be obtained. For example, there are 6 legal input letters of Simplified Chinese Pinyin after the single letter s, which are e, u, i, o, a, h respectively. The only valid input letter following a single letter o is a u. There are three legal input letters after the pinyin string ka, which are i, o, and n respectively; and there is only one legal input letter after the pinyin string kan.

Abstract

An implementation method of a predictive-based adaptive Chinese input method touch screen keyboard. After the user inputs any one or more letters, the next target letter that the user may input is predicted based on the pinyin rules, and each letter on the keyboard is marked Finally, on the basis of not changing the original layout of the keyboard, the size of the target letter key is adjusted and the distance between it and the current key is shortened. The invention can significantly improve the accuracy and efficiency of user input.

Description

technical field [0001] The invention relates to a technology in the field of computer peripheral equipment, in particular to a method for realizing a prediction-based adaptive Chinese input method touch screen keyboard. Background technique [0002] Mobile devices such as mobile phones have become one of the important platforms for people to communicate with others, express emotions, and develop creativity in people's lives, and the use of these devices must require input terminals. As a result, many manufacturers have developed Chinese input methods for mobile devices, and early mobile devices all had their own physical keyboards for input. With the advent of the intelligent era, touch screen devices such as smart phones and smart tablets have entered people's lives, and then touch screen keyboards have replaced physical keyboards. Among various Chinese input method systems, the Chinese Pinyin input method is the most widely used, and the touch-screen keyboards used in the...
