Abstract

The invention discloses a camera pen, a flexible electronic whiteboard and an application system thereof. The application system comprises a flexible material printed with a dot matrix pattern, the camera pen for acquiring positional information according to the dot matrix pattern on the flexible material and a computer, and the camera pen reads the dot matrix pattern on the flexible material, decodes and analyzes the dot matrix pattern to obtain the positional information of the read dot matrix pattern, and wirelessly transmits the positional information to the computer. The portable camera pen reads the dot matrix pattern on the flexible material, and can easily acquire the positional information contained in the dot matrix pattern after decoding and analyzing the dot matrix pattern, and thereby the positioning process on the electronic whiteboard provided by the invention is fulfilled; and the flexible electronic whiteboard is low in fabrication cost and small, and is convenient to carry. Meanwhile, the positioning precision of the system using the flexible electronic whiteboard is high, the fabrication and assembly cost is low, and the popularization of electronic teaching is facilitated.

Description
