10. The method of claim 9 , wherein exchanging the introduction data further comprises: selecting of the introduction data by the user devices from the respective introduction definitions, wherein the introduction definitions are stored local to each respective user device or are stored in a data store local to servers of the gesture-driven introduction system.
9. A method comprising: registering of a portable user device of a first human actor and a portable user device of a second human actor with a location monitoring component of a gesture-driven introduction system using a communications network, wherein the first human actor and the second human actor are members of the gesture-driven introduction system, wherein said registration notifies the location monitoring component of a current location of each user device; and receiving of a notification by the user devices of the first and second human actors indicating that the current location of each user device is within a predefined proximity of each other, wherein said notification is made via a client application running on their respective user devices and specifies at least one gesture to perform to exchange introduction data, wherein the gesture is representative of a discrete non-empty set of deliberate motions whose execution utilizes at least one visible and movable body part; when the first and second human actors each perform a gesture specified in the notification, generating of gesture event data by each user device for their respective human actor, wherein the gesture event data comprises the gesture and at least one ancillary condition regarding performance of the gesture; exchanging of the generated gesture event data between the user devices via the communications network; assessing of the exchanged gesture event data by each user device with respect to at least one introduction definition, wherein an introduction definition is a user-created data structure that defines triggering parameters for exchanging introduction data, wherein the triggering parameters comprise at least one gesture and at least one ancillary condition; and when the gesture event data is assessed as satisfying the triggering parameters expressed in an introduction definition, automatically exchanging the introduction data associated with the respective introduction definition between the user devices of the first and second human actors via the communications network, wherein said exchanging of the generated gesture event data occurs without direct physical or verbal interaction between the first and second human actors.
