Sliding pen input system based on virtual keyboard

Abstract

The invention provides a sliding pen input system based on a virtual keyboard, which comprises a touch screen for displaying the virtual keyboard, an object memorizer and an input method processing module, wherein the virtual keyboard comprises a plurality of virtual keys, a key signal can be generated as long as one key is selected to input, an invalid touch area is formed in the middle area in which the virtual keys are distributed, and the invalid touch area facilitates the continuously selection of each key in a sliding mode for users; the object memorizer is used for storing objects, each object at least associates to a signal sequence; and the input method processing module is used for acquiring the key signals and generating a signal sequence in accordance with the key signals, and the objects associating with the signal sequence are output from the object memorizer in accordance with the generated signal sequence. In the system of the invention, the invalid touch area is formed in the middle area in which the virtual keys are distributed, thus the users can smoothly realize the change from one key to any key through the invalid touch area, false selection can not be generated, thereby realizing the continuous sliding input on the virtual keyboard of the touch screen and improving speed and efficiency of the input.

Description

technical field [0001] The invention relates to an input method technology based on a virtual keyboard, in particular to a sliding pen input system based on a virtual keyboard. Background technique [0002] For portability, the current development trend of electronic products is miniaturization, and the multimedia functions of electronic products require good input and output performance, such as portable handheld computers, personal digital assistants (PDAs), smart phones and other electronic products currently in use. Many of them use touch screen input, that is, use software technology to simulate a virtual keyboard on the touch screen of electronic products, and click the buttons on the virtual keyboard with fingers or stylus to input. The keys of the virtual keyboard generally include several character keys and some character keys. The input needs to select a suitable word selection key, and the characters displayed by this word selection key are input on the text box ...
