Mobile terminal having virtual keyboard and hand-write synergic input function

Abstract

The invention discloses a mobile terminal equipped with virtual keyboard and hand-written synergic input function that includes stylus, touch screen, input device of virtual keyboard and hand-written synergic which is connected with the touch screen, the device includes: sensing unit of virtual keyboard operation which is used to receive the operation signal of button, virtual keyboard input unit which is used to receive the input signal of keyboard, the keyboard input accomplishing processing unit which is used to analyze and process the input signal and output the result to the display; identification unit of hand-written state which is used to identify the stylus contact the touch screen or not, and hand-written course identification unit which is used to judge the hand-written course, and the hand-written trace identification and output display unit which is used to identify, process, and output the handwritten trace. The invention can identify the virtual keyboard input state and handwritten input state automatically, there is no need to set in the input course, and the switch of input mode is easy and convenient.

Description

technical field [0001] The invention relates to a mobile terminal, in particular to a mobile terminal with a virtual keyboard and handwriting collaborative input functions. Background technique [0002] Handwriting input and virtual keyboard input are two input methods that are more and more commonly used in mobile terminal input methods in recent years. The handwriting input method refers to handwriting on the touch screen through the built-in stylus of the mobile terminal. Various handwritten fonts are converted into standard fonts recognizable by electronic product terminals and displayed on the touch screen, which greatly improves the input speed; and the inputter can use it without additional training. The virtual keyboard input method is to display the virtual keyboard on the touch screen, and to input through the selection of the stylus, there are often more buttons on the virtual keyboard, which reduces the number of buttons on the keyboard of ordinary electronic pro...

Problems solved by technology

[0003] However, these two input methods on traditional mobile terminals are used as separate input methods and need to be set and used separately. In electronic products where virtual keyboard input and handwriting input coexist, Chinese character input needs to be selected first. Virtual keyboard input mode or handwriting input mode, the switching between the two modes cannot be completed automatically, which is particularly inconvenient to use and has relatively large use limitations
