Claim 7:
8. The method of claim 1, further comprising:
generating a projection signal including an image of dots or lines, wherein the dots or lines are modulated according to the modulated data,
wherein the transmitting of the modulated data to the first participant user device comprises transmitting the projection signal such that the image having the modulated dots or lines encoded therein is projected onto the face of the participant via an emitter integrated in the first participant user device, and
wherein the conditionally detecting of the modulated data in the video stream comprises verifying whether changes in the modulated dots or lines are reflected by the face of the participant and captured by an imaging device of the second participant user device in the video stream associated with the participant.
