Explore a 21-minute conference talk from the ACM User Interface Software and Technology Symposium that introduces Vizir, a domain-specific graphical language for creating and managing airport automations. Delve into the participatory design process with Air Traffic Controllers, examining how Vizir combines visual programming constructs with activity-related geographic areas and events. Learn about explicit human-control features, graphical substrates, and methods for scaling up multiple automations. Discover guidelines for designing usable hybrid human-automation systems, and gain insights into the challenges of increasing air traffic and the role of automation in addressing them.
