Device, system and method for recognizing handwritings

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.
