Managing location information for a group of users
Abstract:
A user designated as a group leader of a group of users manages location information for the group of users using a base device. In particular, a client device is identified for each user in the group of users and an area within which each user in the group of users is to remain is defined. Subsequently, the base device can obtain location information for the client device(s) and process the location information for use by the group leader. For example, the base device can display the current location of one or more users, display the relative location of one or more users with respect to the group leader, and/or determine if one or more users are outside of the area. The group leader can then coordinate the group by communicating with one or more users in the group. In this manner, the group leader can make more informed decisions about the status of each group member and more efficiently coordinate the re-grouping and/or movement of the group of users.
