Human tracking system embedded in stuffed animal

Abstract

In recent years, the importance of tracking system for children or elderly people is increasing by reduction of a household number of persons, and dilution of the human relations in a community. We aim at developing a tracking system which can be used by small children or dementia patients easily, and pro-pose a human tracking system embedded in stuffed animal which can tweet the location information and picture. This system consists of a Raspberry Pi, camera, two switches, GPS module, battery, speaker, 3G modem, and Wi-Fi adapter. By pushing each switch, a user can take a photo, or obtain location information by GPS module, and tweet them. In addition, this system can also tweet these pieces of information periodically. Since this system can be operated easily, it is realizable to track the small children who cannot operate a smart phone, and dementia patients. Furthermore, since control by the tweeted command can also be performed, a guardian who is present in a remote place can obtain a location and a picture in real time via twitter. We expect that children and elderly people always carries it by holding affection in the stuffed animal itself.
