Resonance, a powerful and pervasive phenomenon, appears to play a major role in human interactions. This article investigates the relationship between the physical mechanism of resonance and the human experience of resonance, and considers possibilities for enhancing the experience of resonance within human–robot interactions. We first introduce resonance as a widespread cultural and scientific metaphor. Then, we review the nature of “sympathetic resonance” as a physical mechanism. Following this introduction, the remainder of the article is organized in two parts. In part one, we review the role of resonance (including synchronization and rhythmic entrainment) in human cognition and social interactions. Then, in part two, we review resonance-related phenomena in robotics and artificial intelligence (AI). These two reviews serve as ground for the introduction of a design strategy and combinatorial design space for shaping resonant interactions with robots and AI. We conclude by posing hypotheses and research questions for future empirical studies and discuss a range of ethical and aesthetic issues associated with resonance in human–robot interactions.

Human-centred design (HCD) is a powerful methodology that might play an important role in the development of real-world intelligent systems. However, present conceptualisations of artificial intelligence (AI) tend to emphasise autonomous, algorithmic systems. If humans are not involved in AI system design, what role can HCD play? This paper considers perspectives that reframe the role of AI in smart systems design, with the intention of creating space for human-centred design methodologies. These perspectives naturally give rise to opportunities for HCD by considering human and artificial intelligence in tandem. Informed by cybernetic theory, we define smart systems as "the use of outcome data to inform successful system action". To illustrate the practicality of this view, we share three case studies, each representing a different smart system configuration: artificial intelligence, human intelligence and combined artificial-human intelligence. We describe Battleship Numberline, an educational game with autonomous artificial intelligence. We then describe Zensus, a smart system for health and well-being that leverages human intelligence alone. Finally, we describe FactFlow, educational software that combines artificial and human intelligence. By examining the cybernetic feedback loops observed in these systems, we contribute a practical framework for the use of human-centred design methodology in smart systems design. This framework is intended as both a generative tool for designers and a basis for future research in the field of smart systems.@en
