Statistically processing it by in real time making teacher's location information visible by using active type RFID in the classroom, and making the movement locus a database becomes possible. However, it is quite difficult in person's location information tracking by active type RFID at the entry level to cause a big error margin, and to compose the system as practical use is endured. However, such a system was cheap and thought about this use because it was widespread to some degree. This system is not necessarily enough though it is thought that it is necessary that the user oneself can do handily construction and the removal, and was able to reach to some degree by it yet. It was uneven to the characteristic of active type RFID tag between individuals, and, as a result there a situation that the location information was not able to be supplemented accurately. Then, the correction between individuals was done by correcting the location information of each tag by the time series, and using two or more tag. The system that was able to understand the location information in some classroom was developed with the system only that was able to understand whether existed by this so far extent.Moreover, it projected to the whiteboard in case of the case to project the screen of PC of the educational environment in a reformative classroom to the screen as a screen presentation method and to operate with the keyboard and the mouse of PC and the consideration investigation by person's of attending a lecture with Electronic white board that was able to do the direct manipulation of the object aspect was done. It is thought that an electronic white board is use of the location information on the whiteboard of an electronic pen, and it is indispensable to understand and to use the location information of various objects in the classroom for the construction of the environment in a comfortable classroom.

通过真实的实时统计处理，使教师的位置信息在教室中使用有源型RFID可见，并使移动轨迹成为数据库成为可能。然而，在入门级通过有源型RFID进行人的位置信息跟踪是相当困难的，从而导致大的误差容限，并且在实际使用中难以构成系统。然而，这样的系统是便宜的，并考虑这种用途，因为它在某种程度上是普遍的。这个系统虽然被认为是必要的，用户自己可以做方便的建设和拆除，并能达到一定程度，但还不够。个体之间对有源型RFID标签的特性不均匀，并且结果存在不能准确地补充位置信息的情况。然后，个体之间的校正是通过使用两个或更多个标签，用时间序列校正每个标签的位置信息来完成的。能够理解某个教室位置信息的系统是用迄今为止能够理解是否存在的系统开发的。作为一种屏幕显示方法，将改造教室的教育环境的PC的屏幕投影到屏幕上，并利用PC的键盘和鼠标进行操作，考虑调查的人参加讲座与电子白色板，能够做的直接操纵的对象方面进行了。认为电子白色板是利用电子笔在白板上的位置信息，理解和利用教室中各种物体的位置信息对于构建舒适的教室环境是必不可少的。
