Expected time for comfort achievement in human-robot emotion communications

Abstract

This paper considers a cyber-physical system consisting of a user, a robot and the computing resources in the cloud. Specifically, the robot reads the emotional state of the user and relies on the cloud to determine the most appropriate action on the environment. Since this process generally involves several interactions until user comfort is achieved, its real-timeliness becomes a critical issue. This problem is addressed in this paper by using a Markovian representation of the emotional state sequence.
