We introduce  Grouper , a proof-of-concept wearable wireless group coordinator. Users wear modules each consisting of a microprocessor, a wireless radio, and various electronics to provide sensory cues to users. These sensory cues alert the users to pay attention to the leader of the group, thus augmenting a leader's ability to direct a group. Wearable devices have been used to observe social interactions but few have been used to coordinate a group of users.
