Currently the research sites of the university are expanding, and experiments are conducted not only in the laboratory but also in other classrooms and sometimes outdoors. However, this has resulted in a situation in which people are dispersed, and there are no people who can respond when there are visitors. Under such circumstances it is difficult to decide where visitors should head. Therefore, we detected the occupancy situation using a human sensor, developed a presence displaying system that can transmit data via 3G line and confirm from the Web browser. |
