Stocco and colleagues 5 extended these results by showing that a Sender and a Receiver can iteratively exchange information using a BBI to identify an unknown object from a list, using a question-and-answer paradigm akin to “20 Questions.” Grau and colleagues 4 proposed a related but offline non-iterative BBI.Įarly interest in human BBIs came from the potential for expanding human communication and social interaction capabilities 6, 7, 8, 9, 10.

However, previous BBIs have lacked several key features of real-world human communication.

First, the degree of interactivity has been minimal for example, in the case of the “20 Questions” BBI 5, the Sender only responds to the question the Receiver chooses, and the Receiver’s performance does not affect the Sender’s decision.
