Abstract
Increasingly autonomous machines may lead to issues in human-automation systems that go beyond the typical concerns of reliance and compliance. This study used an interaction-oriented approach that considers interdependence in coordinating and cooperating on a joint task. A shared-resource microworld environment was developed to assess how changes in environmental demands and agent behavior affect cooperation and system performance. Seventy-two participants were recruited to perform a scheduling task that required coordination with a cooperative and a relatively uncooperative automated agent. Cooperative automation enhanced performance because it provided more resources to the person and because the person provided more resources to the automation. Considering interdependence theory and the associated structure, signal, strategy, and sequence of human-automation interaction can guide design for appropriate trust and cooperation.
