Group Identification in Crowded Environments Using Proximity Sensing

摘要

Children and elderly separating from their family members is a common phenomenon, especially in crowded environments. In order to avoid this problem, places like Disney World and pilgrimage officials have developed systems like wearable tags to determine groups or families. These tags require information about families to be entered manually, either by the users or the facility organizers. The information, if correct, can then be used to help identify and locate a lost person's group. Manually entering information is inefficient, and usually leads to either long waiting times during entry, or partial information entry within the tags. In this paper, we propose a system that uses proximity sensing to determine groups and families without any input or interaction with the user. In our system, each user is given a wearable device that keeps track of it's neighbors using bluetooth transmissions. The system then uses this proximity data to predict cliques that represent family members.
