Description

A kind of multifunction wireless writing pencil

Technical field

The present invention relates to a kind of multifunction wireless writing pencil, belong to the electronic product field.

Background technology

At present the words input of the products such as computer, mobile phone mainly contains keyboard-type and handwritten two kinds.Wherein keyboard-type mainly refers to utilize keyboard and various input method such as spelling input method, stroke input method, five-stroke input method etc. to carry out words input.The handwritten mode that refers to utilize writing pencil, thus identification user's literal track carries out words input.

The keyboard-type input method is a kind of traditional input method, however the switching between the different input mode, and Chinese and English switching, punctuation mark switching etc. can greatly affect the speed of user's literal input.Also have in addition the very important point, computer or cellphone subscriber have a very large user group can not use the keyboard-type input method, and such as the old man etc., handwritten is the important way that they carry out words input.

Handwritten input method generally all two parts form, a part is the board of induction user input, another part is the writing pencil that writes at board.Certainly the user also can any writing pencil, directly write at board with finger, for the cellphone subscriber, board directly is exactly mobile phone screen, the track record that board can be passed by writing pencil or finger gets off, and then the recognizer by any is identified as literal.Therefore can directly write into the typing of style of writing word at the enterprising running hand of mobile phone screen with writing pencil or finger.

This handwritten input is very useful for the people who does not like using keyboard or uncomfortable use Chinese character coding input method, because it does not need to learn any input method.Writing pencil can also be used for accurate mapping, such as input that can be used for circuit design, CAD design, graphic designs, free drawing and text and data etc.

Handwriting pad is connected to computer by wired or wireless mode, and for mobile phone, handwriting pad is exactly its screen.Handwriting pad in the market mainly is divided into two kinds of resistance-type and induction types, and the handwriting pad of resistance-type fully contact just can be write word occurrence, and this has limited the function that writing pencil replaces mouse to a certain extent, receives very big impact with playing after a while sensitivity.And the induction type handwriting pad is divided into " pressure sensitivity is arranged " and " without pressure sensitivity " two kinds, wherein there is the tablet of pressure sensitivity can respond to the thickness of stroke, painted dense what is said or talked about, when in PhotoShop, drawing, have no small effect, but the induction type handwriting pad is subjected to the interference of some electric equipments easily, and serviceable life is limited.

Handwritten input method in the market has following inevitable fatal shortcoming:

(1) life-span is short.Handwriting pad is judged the position by the distortion of inductive material, the inductive material fatiguability, and serviceable life is shorter.

(2) sensitivity is low.No matter be resistance-type or induction type, all need accurately identification of fully contact, sensitivity is low.

Although the action writing pencil that some utilize acceleration transducer occurs in the market, they do not have energy management, can not the control on demand transmission rate save energy.In addition, a lot of people wish literal is backed up when writing.Such as writer or artist, do not like operating on computers, they can utilize more usual the same the writing or draw a picture of writing pencil, can back up with synchronously the information on the paper automatically on computers simultaneously.Existing writing pencil does not have the function of Word message backup.

Therefore, in the urgent need to redesigning a kind of handwritten input method, it is short serviceable life to solve present handwriting pad, and the problem that sensitivity is low has energy management functionality simultaneously.

Summary of the invention

The wireless writing pencil that the present invention relates to, abandon the effect of handwriting pad, main other sensors such as acceleration transducer or angular acceleration transducer that adopt carry out the nib track following, then track data is sent to mobile phone terminal by wireless mode (such as bluetooth etc.), thereby then match suitable stroke according to track comparison stroke storehouse, and then realize the function of words input.This mode replaces the handwriting input mode of traditional employing pressure sensitive, has higher reliability.Adopt sensor to carry out track following and judge stroke, can not need to by any utility appliance, such as handwriting pad etc., the user only need to write with tradition the same, can just move at desk, blank sheet of paper, wall even with the space and can realize words input, owing to can " write " anywhere, the user can according to normal writing style firmly, more meet the characteristics that the user writes usually.

Load onto common pen and ink at the nib of writing pencil in addition, the user that custom is write can write or draw a picture at paper, by sensor track is sent on the other hand the function that the equipment such as computer or mobile phone are realized the information automated back-up.

Writing pencil hardware components of the present invention is divided into pen and ink and writes module, track detection module, wireless radio frequency modules, processor and energy management module.

Wherein, pen and ink are write module and are comprised of the pen and ink in fountain pen or ball pen or the gel ink pen or other writing mediums, main in order to satisfy the demand of information back-up, the user can use this wireless writing pencil when conventional pen on the one hand, can realize on the other hand the information backup of (comprising literal and drawing etc.).

The track detection module, mainly by acceleration transducer or angular acceleration etc. can detecting pen tongue mark sensor form, processor is by control track detection module, the precision determination data acquisition rate that detects according to reality.

Wireless radio frequency modules mainly is comprised of various radio frequency chips.For writing pencil use convenient, adopt wireless mode that the information of track detection is sent to the equipment such as computer or mobile phone.Wireless mode can adopt the lower bluetooth of power consumption.Certainly, can also adopt serial ports in wired or the mode of USB according to user's needs.

Energy management module in order to realize the collection of trace information, needs to consume a large amount of electric weight.Therefore certain energy management module need to be arranged, opening power when the user needs, otherwise powered-down is to save energy.

Writing pencil of the present invention has three mode of operations, general mode, words input pattern, information back-up pattern.At general mode, writing pencil uses pen and ink to write module, and as broad as long with conventional pen, power module is closed energy-conservation energy; The words input pattern, the user only need to write module to pen and ink and close and get final product, can realize like this not taking writing arbitrarily of pen and ink, after the track detection module gathers trace information, be sent to the equipment such as computer or mobile phone by wireless radio frequency modules, then the information that collects is identified, thus the typing of realization Word message; In the information back-up pattern, the user writes at medium with the character calligraph in the general mode is the same on the one hand, and writing pencil is sent to information the equipment such as computer or mobile phone on the other hand, and written information without any need for identification, is directly carried out the track backup.
