Method for realizing visual input on computer handwritten drawing board

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.

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 drawing board to solve the above problems, but it also has the following problems: it is only suitable for liquid crystal display and cannot be applied to general displays; Under the liquid crystal panel, the pressure sensing accuracy of the handwriting drawing board is affected, and the performance is affected; due to the integrated design, the handwriting drawing board cannot be used separately from the liquid crystal display; the manufacturing technology is complicated and the requirements are high
