Application Of Double Pen Touch In The Electromagnetic Interaction Whiteboard

With the rapid development of electronic technology, electromagnetic interaction whiteboard has been widely used in modern teaching. Application of a new technology often has an important impact on educational idea, educational mode and the teaching way in the field of education. It not only improves the teaching environment, but also increase the students’ enthusiasm for learning.In recent years, multi-touch products occupy in the market share is growing, favored by the vast number of consumers, and the prospects are still good. The multi-touch technology is a kind of natural, friendly human-computer interaction, allowing the user to simultaneously through a plurality of contact points to interact with the system. In order to meet the market requirements, this paper designs two-pen touch based on electromagnetic whiteboard with single operation. The main contents cosist of the following six sections:The first part is the prolegomenon. It elaborates the study background of the problem, and explains the problems to be studied and the methods and purpose.The second part quotes the Displaybank analysis that reveals the multi-touch technology will become the main force of human-computer interaction, and through the examples of apple mobile phone to further explain technical trend of mobile phone, tablet computer. This part also defines the multi-touch technology and introduced several main principles on which it is based, and analyzed future development of multi-touch technology from two aspects of technology and market conditions.The third part discusses the human-computer interaction technology as well as the definition, application status and development of the whiteboard.The fourth part is the study of the paper’s research object that is electromagnetic whiteboard. From two aspects of hardware structure and program language on the refinement of the working principle and process of electromagnetic type electronic whiteboard, starting from the details of the wiring rules whiteboard positioning algorithm, including the rough location and precise location of two parts.The fifth part is the design of the electronic whiteboard of electromagnetic type double pen function. Appropriate improvement and program on the hardware circuit structure of the original basis make electromagnetic type electronic whiteboard with relatively simple circuit can realize double pen writing to meet the market trend.The sixth part synthesizing the ideas and discuss of the study, formed a conclusion, and points out the limitations of the study.
