Embodiment Construction
[0007] For handheld mobile devices (such as mobile phones, personal palm computers, handheld entertainment products, etc.), the sensor setting position is designed to be in the area where the user's thumb naturally touches when holding the device with both hands. After starting the virtual keyboard input, when the user's two hands When the thumb touches the sensing area of the sensor and triggers the sensor, a virtual keyboard is displayed on the display of the device. The virtual keyboard can be superimposed on the original image displayed on the display in a translucent manner, or in an opaque form Cover part of the area. Manipulate the movement of the thumbs of both hands up, down, left, and right, and use the sensor to receive the movement direction and position information of the thumbs. The virtual keyboard needs to display two "selection positions" (which can be currently selected by the left and right thumbs of both hands) key), which are respectively mapped to the po...

The invention discloses an input method of a virtual keyboard of a handheld device, which is realized by a sensor installed in a handheld device and a virtual keyboard displayed on a device display screen, wherein the sensor is used for receiving the omnibearing movement and click (pressed by thumbs) of the thumbs of two hands, and the virtual keyboard is used for displaying the choose situation of keys. After the omnibearing movement of the thumbs of two hands is collected by the sensor, thumb movement is converted into the movement switch of a chosen key on a corresponding virtual keyboard keypad, and the movement of the thumbs is reflected on the virtual keyboard. The press (click) of the thumbs represents the typing of the chosen key. After the sensor receives the information of pressing, the system receives the typing of the current corresponding chosen key.
Description
technical field [0001] The invention relates to a virtual keyboard input method of a handheld device. Background technique [0002] Many of the current handheld devices are equipped with keyboards. For the convenience of text input, many devices are even equipped with full QWERTY keyboards. However, these keyboards, especially full QWERTY keyboards, occupy a relatively large space on mobile devices, and the structural design is complex, making these It is not easy for mobile devices to be compact and thin. [0003] The task of the present invention is to provide a virtual keyboard input method for a hand-held device that is convenient to use. By operating the thumbs of both hands, the hand-held device can save the input keyboard that takes up a large space while maintaining convenient and quick text input, and help the device Make it small and light. Contents of the invention [0004] The virtual keyboard method of the present invention is realized by the sensor installe...
