From Serve-on-Demand to Serve-on-Need: A Game Theoretic Approach

Everyone is familiar with the scenario, people demand or assign tasks to robots, and robots execute the tasks to serve people. We call such a model Serve-on-Demand. With the advancement of pervasive computing, machine learning and artificial intelligence, the robot service of the next generation will inevitably turn to actively and exactly meet people´s needs, even without explicit demand. We call it Serve-on-Need. It requires the robots to comprehend the intentions and preferences of people exactly. In this paper, we model the human-computer interaction for Serve-on-Need as a repeated stochastic Bayesian game. We solve the stochastic Bayesian game by an equilibrium analysis and rational learning. We present the service of a coffee robot to illustrate such an approach.
