Abstract

A display and control method for a virtual keyboard of a touch screen is provided. The method comprises the following steps: an operator holds a hand-held electronic device and contacts a touch sensing device of the hand-held electronic device with a finger; an input software system receives and analyzes finger contact information, selectively switches to a contact virtual keyboard interface corresponding to the finger contact information and outputs the contact virtual keyboard interface to a touch display device in a translucency way, and the contact virtual keyboard interface overlaps 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 employing 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 misoperation during input, realizing the highly efficient input of the hand-held electronic device and enabling the usage to be much more convenient, easier and faster.

Description

Display of virtual keyboard for touch screen and control method thereof

The present invention relates to a display and a control method thereof for a virtual keyboard for a touch screen. Background technique

Handheld portable electronic devices include tablet computers, UMPCs, PDAs, mobile phones, etc. In order to highlight the portability and functionality of the device, smaller, thinner and more powerful has become an irreversible development direction for portable electronic devices. The rapid expansion of the functionality of portable electronic devices is limited by the size of the visual interface, which provides the smallest device to the user while maximizing the content of the screen. The requirements for the display of the screen content of the portable electronic device are inconsistent with the development rules for miniaturization of the device. The virtual keys on the touch screen of the portable electronic device have always been crowded by other application display areas, and the limited screen display space cannot fully display the virtual key keyboard interface and the application interface. The touch virtual keys of the handheld portable device are designed to minimize the screen display area of the application software. The keyboard layout is tight, and each virtual keypad is small, which is highly prone to misoperation. In order to achieve as large a virtual keyboard input interface as possible on a limited touch screen area, various efforts have been made. For example: Chinese Patent Application No. 01818103. 1 "Transparent Keyboard Interface on Screen" describes a graphical user interface in the form of a transparent keyboard that can be placed on an existing computer display. The user can select the keys in the transparent keyboard display and enter text data through the keyboard. The text input can then appear on the computer display in an opaque or traditional format. However, it is clear that even if the area of the entire touch screen is used as the display area of the transparent keyboard, the entire keyboard cannot be completely displayed on the display of the handheld portable electronic device. Another application number is

Chinese Patent Application 200510003937. 5 "Transparency in a Size-Limited User Interface" describes a method of increasing the screen space of a computing device by a semi-transparent functional area overlaid on a non-functional content area on the screen. This approach creates conditions for larger functional targets on the screen – alleviating usability issues associated with tiny buttons and other images—while also making the underlying content on the screen clearly visible. In layman's terms, the method is non-functional on the screen. A translucent control menu is superimposed on the energy zone to improve the operability of the small-sized touchscreen. However, since the position and size of the semi-transparent control menu are changing at any time, the position and size of the non-control area of the screen must be calculated before each change of the screen, which increases the burden on the processor, and is easy to cause slow operation and unresponsiveness.

Another patent application of the present application, application number 200910005029. 8 "A method for switching an input interface on a handheld electronic device and a switching device" describes a novel input method that requires the entire keyboard and all input interfaces to be used. The symbol is divided into several input sub-interfaces. Each input sub-interface contains only a limited number of keys, and different input interfaces are switched by several buttons arranged on the side of the device. This method can only switch between the display interface and the input interface, and cannot display different interfaces at the same time. There are certain obstacles when using it.
