Problems solved by technology

[0006] At present, the general handwriting drawing board is a common tool for computer text and graphics input, but because its writing plane does not coincide with the display plane of the computer, the user cannot directly control the writing pen on the writing plane as when using a pen and paper writing method. The starting position, writing strength, etc., affect the accuracy and effect of writing and painting
[0007] There is also a product that combines liquid crystal display and handwriting dr

Embodiment Construction

[0039] Please refer to the accompanying drawings for the embodiments of the present invention.

[0040] exist figure 1 Among them, the reflective mirror (2) in the imaging lens group is a transparent thin plate such as a thin glass plate or a thin optical resin plate that can produce specular reflection on one surface, and the side close to the display screen can be coated with an enhanced reflection film so that the image formed Clearer, it can map the display image (1) to the image (3) on the handwriting drawing board according to the imaging law of the optical plane mirror. When viewed from the position of the eye (4), the image is inverted, and its size is the same as that of the display image on the display. (1) consistent, every point on it to the distance of mirror surface (2) place space plane and the image (3) on the handwriting drawing board are equated to the distance of reflector mirror surface (2) place space plane.

[0041] The image (3) on the handwriting drawi...

Abstract

A device of realizing visual input of hand drawing board on computer is prepared as setting an imaging lens set between writing plane of hand drawing board and displaying plane of display and using adjustable support to fix it, setting a reflection mirror plate in imaging lens set for mapping the displaying image of display onto parallel plane of writing plane on hand drawing board, enabling to transmit light by imaging lens set to let user view actual input area of hand drawing board and to let reflected virtual image of image displayed by display be superposed with actual input area of hand drawing board.
