Emotional affordances in human-machine interactive planning and negotiation

Emotional affordances represent a recently introduced concept which model all the mechanisms used to collect/transmit emotional meaning in the context of human machine interaction. In this work, we introduce and formally define the cognitive role of emotional affordances in a collaboration human-machine dialogue as tools for triggering or recognizing planning-based activities of delegation, goal negotiation, state acquisition, plan prioritization, taking place with the interaction partner. The presented formal model is grounded in an emergency scenario where reacting to emotional affordances or transmitting an emotional content is instrumental to reach the goal of an effective collaborative response. The implementation issues of generation and recognition of emotional affordance are also discussed.
