Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0041] The handwriting input device provided according to the present invention, such as image 3 As shown, the searchlight photoelectric probe 6 and the penholder 7 are included. The searchlight photoelectric probe 6 includes a searchlight photoelectric module. The searchlight photoelectric probe 6 is hinged with the penholder 7; The exit window of the probe 6 emits and receives optical signals, and optical image information such as handwritten characters and hand-drawn im...

Abstract

The invention provides a projector-type photo-electricity module which comprises a substrate, a mouse photo-electricity chip, a lens and a plurality of photo-electricity diodes. The lens enables reflected light generated after light beams of a light emitting diode shine the surface of a handwriting object to form an image on the mouse photo-electricity chip. The mouse photo-electricity chip is used for carrying out collection and conversion of image signals according to the formed image to generate mouse signals. The invention further provides a corresponding handwriting input device and an achievement method. Novel combination and design of a mouse image chip, the lens and a lighting system are achieved, the projector-type photo-electricity structure has a certain depth of focus, and the effective detection range can be determined through adjustment of the brightness of the photo-electricity diodes, the depth of focus of the lens and the reflection coefficient of the surface of an object. The handwriting input device can adapt to stroke direction distortion caused by little inclination of a writing surface; due to the fact that the projector-type photo-electricity module is rotary, the projector-type handwriting input device can adapt to different habits of users in handwriting position, such as left hand writing, right hand writing and back-handed writing, or pen-holding directions.

Description

Technical field [0001] The invention belongs to the field of information technology, in particular to a computer handwriting input device, and particularly relates to a searchlight photoelectric module and a handwriting input device and an implementation method thereof. The invention can be used in optoelectronic technology, computer technology, intelligent control and other professions or industries. Background technique [0002] At present, traditional computer handwriting equipment commonly used technologies are roughly divided into two categories: the first type of solution is a pen-type or finger sensing method based on a touch screen; the second type of solution is a variety of pen-shaped or hand-held devices based on the current photoelectric method of a mouse. The main shortcomings of the prior art are: the first type of solution cannot be written on other surfaces; the second type of solution, due to the photoelectric image sensor of the ordinary optical mouse requires h...
