From Mechanical Assistants to Collaborative Partners
Trace the historical progression from industrial automation and task-oriented robots to adaptive, interactive agents that participate alongside humans. Emphasize how advances in sensing, autonomy, and artificial intelligence transformed expectations, shifting the design challenge from physical capability to effective collaboration. Frame this evolution as a change in relationships rather than technology alone, introducing the idea that modern systems are evaluated by how well they cooperate with people instead of merely executing instructions.
The Human Side of Intelligent Interaction
Explore the cognitive and social dimensions that emerge once machines become interactive partners. Examine trust, communication, shared understanding, predictability, mental models, and user expectations as the foundations of successful human-agent partnerships. Show that effective collaboration depends not only on technical performance but also on how people perceive, interpret, and adapt to an agent's behavior over time.
Redefining Safety for the Collaborative Era
Introduce a broader conception of safety that extends beyond preventing physical harm to supporting reliable, transparent, and psychologically comfortable interaction. Discuss how shared decision-making, explainable behavior, appropriate autonomy, and ethical design influence confidence and long-term cooperation. Conclude by establishing the human-agent frontier as a design space where ergonomics, psychology, and intelligent behavior must be developed together, preparing readers for the themes explored throughout the remainder of the book.

The Psychology of Autonomy
From Human Intent to Machine Goals
Establish a mental model for understanding autonomous systems by separating human notions of intention, consciousness, and judgment from computational goal-directed behavior. Explain how agents transform objectives, constraints, and environmental information into internally consistent decision processes. Emphasize why people naturally anthropomorphize autonomous systems and how replacing intuitive assumptions with functional models leads to more accurate predictions of agent behavior.
Inside the Decision Loop
Examine the sequence through which an autonomous agent observes its environment, interprets available information, evaluates possible actions, and selects responses. Explore how internal state, available knowledge, feedback, uncertainty, and changing environments influence decisions. Contrast deterministic behavior with adaptive and learning-based approaches, illustrating why seemingly unexpected actions often emerge logically from the information available to the agent at the time.
Building Predictable Human-Agent Partnerships
