We are exploring ways to encode information exchange into preexisting natural interaction patterns, both between people and between a single user and objects with which he or she interacts on a regular basis. Two devices are presented to provoke thoughts regarding these information interchange modalities: a pair of gloves that requires two users to complete a "secret handshake" in order to gain shared access to restricted information, and a doorknob that recognizes the grasp of a user and becomes operational only if the person attempting to use it is authorized to do so.
