One of the outcomes of today's proposal meet for my space project was what should happen to allow users who have touched through the applet to recognise and interact with each other in the physical space.
If two people in a crowd identify with each other through the transience2 applet, how can they then recognise each other to engage that interaction further.
While the opportunity exists for a user to send a photo of themselves to the other player, i would be better and more engaging for the user if a more abstract method of recognition were employed. Frances pointed out Blue Building, an architecture whereby the usual sensory cues are obscured by vapour clouds. Peoples' personalities are instead represented by the colour-shifting jackets that they were, set according to the results of a personality questionnaire the person has answered prior to entering.
As visitors pass one another, their coats will compare profiles and change color indicating the degree of attraction or repulsion, much like an involuntary blush - red for affinity, green for antipathy.
Another project that attempts to solve this problem of disconnected recognition is the MLA-undergraduate applet You-Who. Released as a guessing game, players of you-who guess each others' physical identity by playing a process of elimination. Whilst well suited to the game concept, this type of recognition would, for my project, be too slow as the connections are, by definition, transient.
