We explore a novel perspective on Human-Computer Interaction (HCI), conceptualizing it as a dynamic interplay among a diverse set of human and computational agents within a networked system. The essence of our model lies in the understanding that HCI is not just about the human-computer interface, but is fundamentally about coordination and communication within a network of heterogeneous agents. These agents, each with different capabilities, roles, and goals, engage in a continuous process of interaction governed by well-defined protocols and procedures to achieve collective goals, from which potentially unforeseen behaviors may emerge.
