Stress luminescence-based novel electronic signature touch pen

Abstract

The invention belongs to the technical field of electronic signature equipment, and discloses a stress luminescence-based novel electronic signature touch pen. The touch pen comprises a tubular shell;a stress luminescence pen point is embedded in the center of the front end of the tubular shell; a micro-camera is embedded in the side surface of the front end of the tubular shell; a photoelectricconverter is embedded in the back end of the stress luminescence pen point; and a central processing chip and a signal transmitter are fixed in the tubular shell. The stress luminescence pen point directly emits electromagnetic wave light rays under the action of external force; the photoelectric converter collects light information emitted by the pen point; and a micro-lens fixed at the back endof the pen point shoots a writing plane as a video signal and transmits optical information and video information to an upper computer. Compared with a conventional signature pen, a signature containsnot only information of pen point pressure and pen point friction but also speed information during signature; an image is not merely a two-dimensional signature image; the information reliability isimproved; and the signature information security is further improved.

Description

technical field [0001] The invention belongs to the technical field of electronic signature equipment, and in particular relates to a novel electronic signature stylus based on stress light emission. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Traditional paper signatures are widely used all over the world. A large number of signatures are required for written signatures in industries such as counter-type business processing, vehicles and drivers, bank deposit and withdrawal slips, insurance processing, shopping malls, and hotel check-in. , the demand for paper remains high. On the one hand, papermaking will cause excessive felling of trees and land desertification; on the other hand, these signature materials need to occupy a large physical storage space (archive room) and consume a lot of manpower and financial resources; In real life or work, efficiency is the priority, and the emergence of e...

AI Technical Summary

Problems solved by technology

Resistive type uses resistance change to cause position sensing without pressure-sensitive information; capacitive type uses human body current induction to cause position sensing. There are many capacitive touch pens on the market. The use of conductive metal causes the quality of the pen to be heavy, and it feels uncomfortable to use the pen for a long time, and when the pen is actually used, the pen tip is the contact point, and the conductive silicone as the contact point is soft, easy to deform, and cannot be well supported by the wrist. The strength of the writing experience is not good; the electromagnetic type is electromagnetic induction that causes position sensing to contain pressure information but has a built-in pressure sensor, so it needs to be jointly built with a stylus that can emit electromagnetic signals and a built-in pressure sensor and an electromagnetic touchpad. cannot be separated

Small electronic devices such as POS machines and mobile phones can be easily carried, but medium-sized electronic devices such as hand-painted boards and hand-painted screens are not only large in size but also cannot be bent and folded, which will be inconvenient to carry

[0005] In summary, the problems in the prior art are: Resistive and capacitive stylus developed earlier and are relatively low-end products. They can only represent the position information during the writing process, that is, the lines are simplistic, and cannot compare with the slight difference in handwriting in real life with different forces. Real ink writing experience

The electromagnetic induction stylus is a high-end product. It can not only represent the position information, but also the sensor installed in the pen can sense the pressure information, making the writing experience more real. It is realized by the electromagnetic field established between the stylus and the tablet, so the electromagnetic stylus can never be separated from the shackles of the tablet
