Keyboard with variable key surface size

Abstract

The invention discloses a keyboard with a variable key surface size, and belongs to the technical field of input systems. The system comprises: an input vocabulary statistics module used for recordingthe occurrence frequency of different vocabularies and storing the occurrence frequency; a calculation module which is used for calculating the occurrence probability of another character after one character; and a key size adjusting module which is used for changing the size of the key. According to the keyboard, the input words can be received, the word bank can be expanded, the words in the expanded word bank are analyzed, the occurrence probability of another character after a certain character is input is obtained, and the key surface size of the key is changed through the occurrence probability of different characters, so that the probability that a user presses a non-target key is reduced, and the input accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of input systems, in particular to an input system with variable key surface size of keyboard keys Background technique [0002] At present, the input system of a smart phone usually uses a 26-key keyboard, a 9-key keyboard, and a handwriting keyboard, wherein the 26-key keyboard and the 9-key keyboard belong to the key keyboard. When a user uses a small-screen mobile phone, that is, a 26-key conventional keyboard in a mobile phone with a screen size smaller than or equal to 4.7 inches, or uses a 26-key keyboard with one hand in a large-screen mobile phone, the size of the keys is too small and the arrangement of the keys is very compact. It may be accidentally touched, that is, pressed on the surrounding keys of the target key, thereby affecting the accuracy of the input. [0003] At present, the existing input software has added functions such as automatic correction, input prediction and fuzzy pi...

Problems solved by technology

[0004] The patent with the application number 201910250454.3 proposes a technical solution for the keyboard layout adaptive input system, which adjusts the keyboard layout by changing the size of the keys, but judging from the final display effect of the solution, there will be abnormal shapes in the adjusted keyboard The case of keys, such as rectangular keys

Moreover, the adjustment range of this scheme is too large. In the current 26-key keyboard, when the size of a certain key in a certain row is adjusted, the space of the other two rows will be occupied. In extreme cases, if a plurality of keys in a certain block of the keyboard It needs to be enlarged at the same time, which will eventually affect the overall appearance and further affect the input experience
