Position and Orientation Detection of Stored Object Using RFID Tags

Radio Frequency Identification (RFID) technology already plays a major role in many areas. One of the applications is for object detection. RFID is used for effective object's identification. A good example is object detection at storage management system. It is applicable to the environment where people easily forget the places of the stored object. In the other hand, the automatic object detection will be useful for disabled people like blind person such that they need information before pick up and store object while doing their daily life activities. As a solution of these problems, this study is proposed in order to assist the disabled people by develop an intelligent storage system which has database to store and inform the position and orientation of object stored using the idea of 'Intelligent Space'. In this article, the methodology and experiment validation to determine the position and orientation of object storage will be presented. The system consists of object storage, object shelves, RFID reader, and RFID tags. RFID tags are attached to the object storage. Meanwhile, RFID reader is at fixed position and detects tags' data to obtain the coordinates of stored object. The information represent the coordinate of stored object is located as well as how the object is oriented. The orientation provides useful information to the intelligent storage system which the user may know whether the object is placed in upside down position or otherwise.
