On May 21, DARPA announced its Enhancing Design for Graceful Extensibility (EDGE) program, which aims to create a suite of human-machine interface (HMI) design tools to be integrated into systems design processes. By prioritizing and orienting these tools towards quantifying, supporting, and testing situational awareness – rather than on cognitive load at the expense of situational awareness – EDGE will help create HMI systems that allow operators to not just monitor autonomous systems but also adapt their use to meet the needs of unanticipated situations.
“As highly-automated machines and AI-enabled systems have become more and more complicated, the trend in HMI development has been to reduce cognitive workload on humans as much as possible. Unfortunately, the easiest way to do this is by limiting information transfer,” said Bart Russell, EDGE program manager in DARPA’s Defense Sciences Office. “Reducing workload is important, because an overloaded person cannot make good decisions. But limiting information erodes situational awareness, making it difficult for human operators to know how to adapt when the AI doesn’t function as designed. Current AI systems tend to be brittle – they don’t handle unexpected situations well – and warfare is defined by the unexpected.”
The EDGE design tools will focus on supporting the ability of operators of autonomous systems, who are not necessarily data scientists or AI experts, to understand enough about the abstract functioning of a system that they can adapt with it when they encounter off-nominal situations. Designers will be able to leverage EDGE design tools to create HMIs that help operators understand an AI system’s processes, or how it works; the system’s status against its performance envelope (i.e., if it’s in its “comfort zone,” or near the edges of its speed, range, etc.); and the environmental context, which is often where the most unanticipated elements come in.
“We need HMIs that do a better job of exchanging information between the system and the human,” Russell said. “There’s a lot of work right now focused on designing machines to understand human intentions, called AI Theory of Mind. I’m interested in helping humans better understand the complex systems they’re teamed with. EDGE is specifically focused on the Observe, Orient, Decide and less on the Act in the OODA loop. It’s not about how fast you press a button, or the ergonomics of your cockpit, it’s about how well you perceive the information that’s coming to you and does that help you develop sufficient understanding of systems processes, status against the machine’s performance envelope, and the context in which it’s operating to still complete a mission despite off-nominal conditions.”
The suite of EDGE HMI design tools will include models that quantify situational awareness demands to enable detailed co-design between software engineers and HMI designers; composable design methods to speed and mature design implementation; and an HMI breadboard for realistic test and verification early in the design process.
A webinar Proposers Day for interested proposers is scheduled for June 1, 2021. More information and details about registration are available here: https://go.usa.gov/xHSKg. A Broad Agency Announcement (BAA) solicitation is expected be available on beta.SAM.gov in the coming weeks.
