A dataset of human and robot approach behaviors into small free-standing conversational groups
Fig 2
Each of the three players in the conversational group has a card with a word on it. Only one word card is different. The player who holds the odd card is the spy, but players do not know what cards the others have. They take turns to describe the word until the adjudicator (either a robot or a human) approaches the group to identify the spy. In this example, player B is identified as the spy and all the players show their cards to confirm that the identification is correct.
