New research suggests that the real power of eye contact is not simply whether it happens, but when it happens. In a first-of-its-kind study, scientists found that the timing and sequence of gaze can strongly shape how people understand and respond to others, including virtual partners and robots.
The study was led by cognitive neuroscientist Dr. Nathan Caruana at Flinders University’s HAVIC Lab. A total of 137 participants took part in a block-building task alongside a virtual partner, allowing researchers to track how different gaze patterns influenced interpretation and behavior.
The Gaze Pattern That Felt Most Meaningful
The researchers identified a gaze sequence that worked best for signaling a request: first looking at an object, then making eye contact, and then looking back at the same object. This specific pattern made participants most likely to read the gaze as a clear call for assistance.
According to Dr. Caruana, the findings show that communication is not just about how often someone looks at you, or whether they look at you at the end of a series of eye movements. Instead, it is the broader context and order of those movements that makes the behavior feel meaningful and communicative.
One of the most striking results was that people reacted in essentially the same way whether the gaze behavior came from a human or a robot. The team says this supports the idea that the human brain is generally tuned to detect social cues, and that people can engage smoothly with robots and virtual agents when those systems use familiar non-verbal signals.
Why The Findings Matter Beyond Robotics
The researchers say the work could help guide the design of social robots and virtual assistants that are increasingly present in schools, workplaces, and homes. Beyond technology, understanding how gaze works could also improve non-verbal communication training in high-pressure environments such as sports, defense, and noisy industrial settings.
The findings may also be useful for people who depend heavily on visual cues, including those who are hearing-impaired or autistic, by informing clearer communication strategies and support tools.
What Researchers Want To Study Next
Next, the team plans to examine other factors that shape how gaze is interpreted, such as how long eye contact lasts, whether looks are repeated, and what people believe about the entity they are interacting with, whether human, AI, or computer-controlled.
The HAVIC Lab is continuing applied studies on how humans perceive and interact with social robots in real-world environments, including education and manufacturing. The researchers argue that these small signals are fundamental to social connection, and that understanding them better could lead to technologies and training that help people communicate with more clarity and confidence.
