ISE Presents a Seminar by Mike Rayo

Display Design to Facilitate Graceful System Extensibility: Data-dense Displays and Interrogating Interactions

A seminar by Michael F. Rayo, PhD, Senior Researcher and Lecturer

Department of Integrated Systems Engineering, The Ohio State University

Wednesday, January 13 at 4:00 – 5:00 pm

120 Baker Systems, 1971 Neil Ave.

Dr. Rayo will speak about one of Cognitive Systems Engineering’s contributions to Visual Analytics: the requirement that human-machine systems gracefully extend past the boundaries of their initial design. Said another way, high-consequence systems must detect and recover from situations that were not considered during design. He will share some preliminary data that indicate that systems that maximize parallel, symmetrical interactions between agents are best suited to perform in non-routine and exceptional circumstances, but do not sacrifice the efficiencies that serial, hierarchical interactions promise for normative circumstances. Dr. Rayo will speak about his past, present, and future work in alarm evaluation and design as well as decision support design. He will speak about common design issues for these types of technology, as well as some unique issues of the healthcare industry. Specifically he will address the issue of ascertaining applicability. First, how do operators know when to trust machine guidance, and when to disregard it? Second, how do we design new technologies that support operators’ ability to make this decision? Two potential strategies, data-dense displays and interrogating interactions, will be explored.

Mike Rayo, PhD is a Senior Researcher and Lecturer in the Department of Integrated Systems Engineering at The Ohio State University, and serves as a scientific advisor in the Department of Quality and Patient Safety at The Ohio State University Wexner Medical Center. His work focuses on improving joint human-machine system performance with a specific focus on display design that increases available information without increasing mental workload. His work in alarm design and management, computerized decision support, and interpersonal communication has been funded by the National Patient Safety Foundation, the Agency for Healthcare Research and Quality, and the Office of Naval Research. He has published numerous papers on healthcare quality and human factors engineering, and serves on multiple patient safety committees and advisory groups.
