Embodiment Construction

[0045] figure 1 It is a schematic diagram of the composition structure of the writing stroke recognition device of the present invention, such as figure 1 As shown, it includes an acquisition module, a stroke recognition module, and a storage module for storing the corresponding relationship between the amount of exercise information and the stroke information, where:

[0046] The collection module is used to collect the movement amount information of the writing stroke recognition device itself and output it to the stroke recognition module.

[0047] The collection module may use an acceleration sensor to collect the acceleration value of the writing stroke recognition device itself in the spatial direction, and the acceleration value is the movement amount information of the writing stroke recognition device itself.

[0048] The acceleration sensor can only measure acceleration, that is, there is acceleration when there is movement (movement cannot be at a constant speed, und...

Abstract

The invention provides a stroke writing recognition device, a mobile terminal and a method for realizing spatial writing. The stroke writing information and the relative writing position information are obtained by collecting and analyzing the writing motion quantity and by utilizing the corresponding relationships among the preset motion quantity information, the stroke information and the relative stroke position information, and the corresponding characters are further recognized by using the obtained stroke writing information and the relative writing position information. The invention ensures the accurate recognition of the stroke writing through the simple hardware circuit and the rich and effective corresponding relationships, and provides a simple and accurate handwriting output mode.

Description

Technical field [0001] The invention relates to a mobile terminal man-machine interface interaction technology, in particular to a writing stroke recognition device, a mobile terminal and a method for realizing spatial writing. Background technique [0002] At present, mobile terminals such as mobile phones include human-machine interfaces: keyboard input, handwriting input, voice input, fingerprint input, etc. Among them, the most commonly used man-machine interfaces for text input are keyboard input and handwriting input. At present, the handwriting input method uses a touch pen to move on the touch screen. The touch screen collects the change in resistance through analog / digital (A / D), and locates the coordinates of the contact point within the plane of the specified area. This method has a recognition rate High, is the mainstream of handwriting input at present. However, the current handwriting input method requires the operator to operate with two hands. Summary of the inve...
