摘要：An increasing number of computer applications involve multiple users. Examplesare peer-to-peer applications, which allow groups of people to share pictures and textdocuments, and computer supported cooperative work (CSCW) applications, whichsupport groups of users in working together on a specific task. Group creation becomesespecially difficult in a mobile setting when mobile users need to interact in often short-lived groups using their mobile communications devices. The formation of groupstypically requires users wishing to invite others to join the group to transfer informationabout the group to the invitee. We enable this by presenting a sequence of dynamicallygenerated visual tags, such as one-dimensional bar codes, glyphs, text, or 2D encryptedtags using a communications device that is a member of the group. An invited userinitiates a camera application on her/his mobile device and decodes images of the visualtags in real time. Information about the group is contained in the tag, such as the identityof one or more existing members, identity of an application making use of the usergroup, information about a peer group management operation to be carried out,information about the error detection algorithm used to protect the tags, and

information about the number and sequence of tags. By transmitting information about

multiple group members using dynamically generated tags the group creation processbecomes more reliable, enabling mobile devices to deal with connectivity restrictionssuch as firewalls and network address translators. In a preferred embodiment,functionality to identify and extract the group information from the tags is providedintegral with a camera application.
