System for Maintaining the Integrity of a Tour Group

摘要

A group of tourists traveling, for example, in a foreign land needs to be sure that no-one becomes lost. Embodiments of the present invention take advantage of mobile wireless terminals colloquially known as “smartphones” to quickly identify any members of a tour group that stray from the group, and to help them rejoin the group. Also, with the assistance of a Central Command Center, appropriate authorities such as a tour leader or relatives can be automatically notified, and search operations initiated if needed.
