A gesture-enabled electronic communication system informs users of gestures made by other users participating in a communication session. The system captures a three-dimensional movement of a first user from among the multiple users participating in an electronic communication session, wherein the three-dimensional movement is determined using at least one image capture device aimed at the first user. The system identifies a three-dimensional object properties stream using the captured movement and then identifies a particular electronic communication gesture representing the three-dimensional object properties stream by comparing the identified three-dimensional object properties stream with multiple electronic communication gesture definitions. In response to identifying the particular electronic communication gesture from among the multiple electronic communication gesture definitions, the system transmits, to the users participating in the electronic communication session, an electronic object corresponding to the identified electronic communication gesture.
