This paper (PDF) from IBM Research discusses socially translucent interfaces, which make perceptually-based social cues visible to their users. The paper shows how a socially translucent interface designed by IBM called Babble can be used to simulate social situations such as lines, lectures, and auctions. The system makes an attempt to restore some of the social cues that make real auctions rich and engaging experiences. The auction is represented as a circle, and each participant is represented by a colored dot. If the participant has accessed the auction page within the last 3 minutes, their dot is shown in color; after that, it turns gray. People who only look at what's for sale are shown around the outside of the circle; when people place bids, they move into the circle, and are positioned in a way that shows the relative magnitude of their bids. Thus, the auction proxy reveals how many have shown interest, how many have bid, what the spread of bidding is, and how many people are 'present' and thus, perhaps, candidates for entering the bidding at the last minute (see screenshot).
