Abstract

The invention relates to an electronic white board and a positioning method thereof, in particular to an electromagnetic interactive electronic white board using a pointer device with no battery and a positioning method thereof. The electronic white board uses a plurality of signal management devices to respectively control the antenna substrate in the electronic white board to send out electromagnetic energy so that the energy-sending processes can not interfere mutually and the false judgement on the position of the pointer device with no battery can not be caused. In addition, the battery can be replaced by using the antenna substrate in the electronic white board to send out electromagnetic energy and energy can be provided for the pointer device with no battery to emit electromagnetic signals, thus the electronic white board is more environmentally friendly and practical.

Description

technical field [0001] The invention relates to an electronic whiteboard and its positioning method, in particular to an electromagnetic interactive electronic whiteboard using a battery-free indicator device and its positioning method. Background technique [0002] In recent years, electronic whiteboards have been widely used in various conferences, seminars and schools for briefing, explanation and teaching, especially interactive electronic whiteboards, which have been introduced into school classrooms in many countries in recent years. Use it as a teaching aid to build a high-efficiency electronic (e) classroom. For example, 50% of the classes in primary and secondary schools in the UK had interactive electronic whiteboards in 2007, and other countries, such as the United States, Australia, Hong Kong, Japan, Singapore, Mexico, and Malaysia, have also gradually adopted interactive electronic whiteboards. Electronic whiteboards are used for teaching, and in recent years, ...
