Pen interaction method and system based on handwriting input state adaptive judgment processing

Abstract

Provided is a pen interaction method based on handwriting input state adaptive judgment processing. In the process of carrying out hand-printed graphic inputting and hand-written character inputting by a user, the current input state of the user is automatically judged, real-time processing feedback is carried out, the user does not need to use a mouse or a keyboard or other interaction device to intervene, display state switching is not needed, and the interactive intention is expressed smoothly. The method defines the character input gesture, and the gesture not only differs from other basic graphs, but also has the ambiguous definition with the basic graphs forming the composite graph. The designed character input state judgment processing method and the note position judgment method can automatically judge the note input states and the note positions of the independent character object or the aiming symbol. The method can simplify the user operation procedures, the user can finish the pen interaction naturally and efficiently, certain universality and extendibility are achieved, and the method can be applied to the professional fields such as pen-interactive-based mechanical aided design and command and control.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction input, in particular to a pen-type interaction method and system based on handwriting input state adaptive judgment processing. Background technique [0002] The traditional graphical user interface is based on the desktop metaphor, adopts the WIMP (Window, Icon, Menu, Pointing) interaction paradigm, and uses the mouse and keyboard as interactive devices to realize human-computer dialogue. Pen interaction is based on the metaphor of pen and paper. Through input devices such as writing pads and touch screens, it collects the user's input trajectory based on stylus or fingers, helping people to easily capture ideas, record events, perform abstract thinking and describe images. Because it provides a natural and convenient operation mode, pen-based interaction has a wide range of application requirements in many fields such as computer-aided design, computer animation and virtual re...
