ELECTRONIC WHITE BOARD SYSTEM, ELECTRONIC STYLUS AND WRITING METHOD

摘要

An electronic stylus is configured for writing on an electronic white board. A color of a surface of the electronic stylus is corresponding with a writing color of the electronic stylus. The electronic stylus comprises a sensing hole, an optical sensing module, and a signal output module. The sensing hole is defined through a side wall of the electronic stylus. The optical sensing module and the signal output module are arranged in the electronic stylus and face the sensing hole. The optical sensing module is configured for generating a blocking signal representing the writing color of the electronic stylus when the first sensing hole is blocked. The signal output module is configured for sending out the blocking signal. The present disclosure also relates to an electronic white board system and a writing method.
