The Importance of Human Stance in Reading Machine's Mind (Intention)

摘要

Our aim is to implement a mind-reading capability in machines and artifacts. We give a formulation of mind-reading applicable to machines, emphasizing the importance of a human stance to a machine in mind-reading. Next we demonstrate how the stance a human takes can modify the recognition of intention in an object/agent, taking as examples experiments conducted by us, I.e., a moving box experiment, eye-contact robot, gaze-game experiment, and three-card-game experiment. To realize a human-machine communication based on mind-reading, it is essential that a human takes an intentional stance to the machine. We have to use signs of intentionality to trick a human to take an intentional stance. Shared attention is shown to work as a sign of intentionality.
