Embodiment Construction

[0015] Such as figure 1 Shown is a system architecture diagram of a preferred embodiment of the electronic device of the present invention. The electronic device 100 includes a touch screen 10 , a virtual keyboard control system 20 and a monitoring unit 30 . The touch screen 10 is used for displaying various display data of the electronic device 100 . The monitoring unit 30 is used for monitoring the tilt angle of the electronic device 100 . The monitoring unit 30 may be a Gyroscope (gyroscope). The monitoring unit 30 monitors the inclination angle of the electronic device 100 based on the angle when the electronic device 100 is placed vertically. Such as figure 2 (a) is a schematic diagram of the electronic device 100 placed vertically. The electronic device 100 is located in the three-dimensional space coordinate system OXYZ, wherein the XOZ plane is the plane where the touch screen 10 of the electronic device 100 is located, and the touch screen 10 faces the user. Th...

Abstract

The invention relates to a virtual keyboard control method which comprises the steps as follows: constructing a virtual keyboard; setting a moving angle threshold of the virtual keyboard, and the moving amplitude and moving direction of the virtual keyboard corresponding to each inclination determinate angle; when an electronic device enters a editing state, displaying the middle part of the virtual keyboard on a touch screen, reading the inclination angle and recording as an initial angle; real-time reading the inclination angle of the electronic device; correcting the read inclination angle to obtain the practical inclination angle of the electronic device, and determining the moving amplitude and the moving direction of the virtual keyboard according to the practical inclination angle and the angle threshold; and controlling the virtual keyboard to move toward the determined moving direction by the determined amplitude. The invention further provides a virtual keyboard control system. According to the invention, a user can conveniently input by using the virtual keyboard.

Description

technical field [0001] The invention relates to a virtual keyboard control system and method. Background technique [0002] The mobile phone is a portable communication tool. In order to maintain the characteristics of portability, most mobile phones cannot provide a large-sized keyboard for users to input text, and the same key can input several characters. Current touch-screen mobile phones provide a virtual keyboard for user input, but each key on the provided virtual full keyboard is also relatively small. Cause the user to not only have to bother to find out the position of the character, on the other hand it is not easy to press the desired button, which makes the user's input very inconvenient. Contents of the invention [0003] In view of the above, it is necessary to provide a virtual keyboard control system and method to facilitate user selection and input. [0004] A method for controlling a virtual keyboard, running on an electronic device, the method compris...
