Abstract

A writing device assembly and a writing content identification method are provided. The assembly includes a writing apparatus including a pressure sensing unit, an optical identification unit and a processor, and a writing medium having code points printed thereon. The pressure sensing unit generates a pressure sensing signal when sensing that the writing apparatus contacts the writing medium. The optical identification unit captures a code point image of the code points in the writing medium when the pressure sensing unit generates the pressure sensing signal, analyze the code point image to obtain a code point value, and send the code point value to the processor. The processor identifies a code point type of the code point value, analyzes the code point value to determine a writing trace when the code point type is identified to be a coordinate code, and identifies the writing trace to obtain writing content.
