A Study of Educational Environment Infrastructure applied of Local Positioning System using Active type RFID

利用有源射频识别技术对教师的位置信息进行实时统计处理，使教师的位置信息可视化，使运动轨迹数据库化成为可能。然而，在入门级的有源RFID对人的位置信息进行跟踪时，由于存在较大的误差范围，难以构成实际使用的系统。然而，这样的系统是便宜的，并且考虑到这种用途，因为它在某种程度上是广泛的。该系统虽然认为用户自己可以方便地进行构建和移除是必要的，但还不够，目前已经能够达到一定程度。个体之间对有源型RFID标签的特性不均衡，导致无法准确补充位置信息的情况。然后，通过时间序列对每个标签的位置信息进行校正，并使用两个或多个标签进行个体间校正。能够理解某些教室位置信息的系统是与目前为止能够理解是否存在的系统一起开发的。此外，本文还针对该案例，将改革课堂教学环境的PC屏幕投影到屏幕上，作为屏幕呈现的方法，使用PC的键盘和鼠标进行操作，并对使用电子白板听课的人进行了考虑调查，该电子白板能够对对象方面进行直接的操作。认为电子白板是利用电子笔白板上的位置信息，了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。

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.
