This paper presents a solution for personal profiling system based on user-oriented tracking. Here, we introduce a new way to identify and track humans by using two types of cameras: dome and face camera. Dome camera has a wide view angle so that it is suitable for tracking human movement in large area. However, it is difficult to identify a person only by using dome camera because it only sees the target from above. Thus, face camera is employed to obtain facial information for identifying a person. In addition, we also propose a new mechanism to locate human on targeted location by using grid-cell system. These result in a system which has the capability of maintaining human identity and tracking human activity (movement) effectively.

In RFID-based cold-storage systems, product locations are recognized as the logical locations of RFID readers which are attached to the entrance of the cold rooms. However, through these methods, product locations can be incorrect in many different situations of a storage. Cold storage rooms have a huge rage in temperature, and the product in the cold-storage spoils easily. Therefore, highly precise product locations is very important for the product quality In this paper, a new approach is suggested to manage the storage location inaccuracy by adding two readers to existing forklift and attaching RFID tags to the ceiling. One reader recognizes ceiling tags to acquire location data, and the other recognizes product tags to acquire product detail data loaded on the forklift. The product can be seamlessly tracked and traced in realtime by monitoring and analyzing data gathered from these readers. Through the proposed location management method, the effectiveness of the product management in cold-storage can be improved consequently.

This paper contains the design and implementation results of a package tour management application using a Geofence technology as well as the performance evaluation. This application ables the tour guide to monitor the tourist movement in real-time whether the tourists are inside the virtual polygonal Geofence set by the tour guide. Even when the tour is moving between travel destinations, a virtual circular Geofence can be set by the tour guide to monitoring the tourist movement while on the move. The application includes tour guide's and tourist's locations, schedule and participant management. To evaluate the performance, average response time and accuracy is measured, resulting in satisfactory performance. The average response time ranged from 0.0047 seconds to 7.3 seconds in various cases and for accuracy, it scored 100% in various cases. It is expected that implementing Geofence technology to package tour management applications will help tour guides to perform more productive package tours by reducing the burden of managing tourists.
