A Novel Emotion Control System for Embedded Human–Computer Interaction in Green Iot

The green Internet of Things (IoT) technology has increased the need for a more emotion-connected human-computer interaction. The lower network latency and longer battery life ensure the continuous and real-time work of human-computer interaction systems in embedded environments. However, the lack of emotional dynamics limits the empathy capability of human-computer interactions. In this paper, we propose a novel emotion control system for embedded human-computer interaction in green IoT. The Van Der Pol emotional dynamics with nonlinear resilience is proposed for the modeling of human emotional mechanisms. Moreover, respectively for the autonomous and stochastic-excitation situation, we analyze the stability of the solution, based on which four kinds of the emotional health status are defined. Finally, we obtain the steady-state solution and design its feedback controller. Results of the numerical simulation and prototype demonstrate the validity and practical operability of the theory.
