Agent software can perform tasks automatically on behalf of a user, but how does the agent come to learn what the user wants? Sometimes the agent can learn just by observing user behavior, but there may also be instances where the user must instruct the agent more explicitly. This "instructibility" aspect is the focus of this project. The user may present examples of behavior that the agent should follow and give advice to the agent as to how the examples should be interpreted. The agent must give feedback to the user so that the user understands what the agent knows and is capable of doing. Multimodal interaction is important in both the instruction and feedback.
