Abstract

The invention relates to a display and control method of a virtual keyboard used for a touch screen, which comprises the following steps: an operator manually holds hand-held electronic equipment andcontacts with a touch sensing device of the hand-held electronic equipment through fingers; an input software system receives and analyzes finger contact information,, selects and switches a contact virtual keyboard interface corresponding to the input software system and outputs the contact virtual keyboard interface to a touch display device in a semitransparency way to be overlapped with a background picture; a display system of the touch screen receives the information of pressing the virtual keyboard and transmits the information of pressing the touch screen into the input software system; and finally, the input software system outputs the inputted contents to other application software. By using the method, the interface of the application software and the interface of the virtual keyboard can be both maximumly displayed on the touch screen, thereby increasing the area of a virtual key field, reducing maloperation during input, realizing the highly efficient input of the hand-held electronic equipment and enabling the usage to be much more convenient, easier and faster.

Description

technical field [0001] The invention relates to a display and control method of a virtual keyboard used in a touch screen. Background technique [0002] Hand-held portable electronic devices include tablet computers, UMPCs, PDAs, mobile phones, etc. In order to highlight the portability and functionality of the devices, smaller, lighter and more powerful devices have become an irreversible development direction for portable electronic devices. The rapid expansion of the functions of portable electronic devices is limited by the area of ​​the visual interface. To provide users with the smallest device and at the same time require the maximum screen content. The requirements for displaying the screen content of portable electronic devices are not consistent with the development rules of device miniaturization. The virtual keys on the touch screen of the portable electronic device always occupy the display area of ​​other application programs, and the limited screen display spa...
