Device, system and method for recognizing handwritings

Abstract

The invention discloses a device for recognizing handwritings of an electronic pen. The device comprises a writing event sensing module, a handwriting plane image recognizing module, a zero point coordinate establishing module, a linear distance calculating module, a shot coordinate calculating module, a handwriting coordinate calculating module, a handwriting coordinate tracking module and a data synchronous transmitting module. The invention also discloses a device of mobile equipment used with the electronic pen. The device comprises a data receiving module, a coordinate establishing module, a data processing module and a handwriting displaying module. The invention discloses a system comprising the device. A user writes on paper with patterns by using the electronic pen; handwriting coordinates are positioned by the patterns on the paper, so that initial handwriting coordinates and relative handwriting coordinates of the electronic pen in a writing event can be obtained; the handwriting events are converted into displaying coordinates to be displayed in the mobile equipment; and displaying handwritings are sequentially connected to one another via the mobile equipment to really reflect the handwriting of the user.

Description

technical field [0001] The invention relates to the technical field of mobile devices, in particular to a device, system and method for handwriting recognition. Background technique [0002] As an electronic device, the electronic pen is being developed more and more. It can be used together with paper and display devices, so that the handwriting written by the user on a specific paper with an electronic pen can be completely displayed on the display device or saved in the computer, which is easy to use. During use, the most critical issue is to completely recognize the handwriting of the electronic pen. [0003] In the prior art, methods for recognizing electronic pen handwriting mainly include the following: [0004] 1) Laser locator, such as patent 201220304981.5, scans the trajectory of the pen into a document through the laser locator and records it, and converts it into an electronic document. However, under this technology, the user can only scan and record the wri...

Problems solved by technology

However, this technology uses a camera to take pictures, and it cannot recognize the coordinates of handwriting in two-dimensional space, so its application range is limited

[0007] It can be seen that most of the electronic pen handwriting synchronization methods in the prior art use the camera on the electronic pen to take pictures, which cannot recognize the coordinates of the handwriting
