MATT ADAMS, NICK TANDAVANITJ, and JU ROW FARR, Blast TheoryWe explore the approach of performance-led research in the wild in which artists drive the creation of novel performances with the support of HCI researchers that are then deployed and studied at public performance in cultural settings such as galleries, festivals and on the city streets. We motivate the approach and then describe how it consists of three distinct activities -practice, studies and theory -that are interleaved in complex ways through nine different relationships. We present a historical account of how the approach has evolved over a fifteen-year period, charting the evolution of a complex web of projects, papers, and relationships between them. We articulate the challenges of pursuing each activity as well as overarching challenges of balancing artistic and research interests, flexible management of relationships, and finally ethics.

Emerging robotic technologies are enabling the control of individual seats on rollercoasters and other thrill rides. We explore the potential of breathing as an effective and engaging way of driving this. Observations and interviews from trials of an enhanced bucking bronco ride show that breath-control is fun, challenging and intelligible, and reveal riders' tactics as they battled the machine. We conclude that breath control is feasible and appropriate for controlling rides, unpack its important characteristics, and consider how it might be built into future ride systems. We argue that the combination of voluntary and involuntary factors in breathing is especially appealing for controlling rides as it balances game-like elements of skill and learning against the thrill of surrendering control to the machine.
