Cornell University researchers announced on Apr. 2 the development of MirrorBot, a mirror-equipped robot designed to encourage social interaction between strangers.
The project, led by Keith Evan Green and members of the Architectural Robotics Lab, aims to address the lack of connection often observed in shared public spaces. By using technology as a tool for engagement rather than isolation, the team hopes to create new opportunities for people to connect.
MirrorBot stands four feet tall and features dual mirrors that allow two people sitting together to see themselves in one mirror and each other in the other. In a study conducted in a waiting-room setting with participants aged 18 to 50, MirrorBot prompted conversations and playful exchanges among strangers. The findings indicate that robots can serve not only as conversational partners but also as spatial mediators.
"We weren't just trying to trigger conversations, but to support the very first moment of social connection, which is the eye contact," said Serena Guo, lead author of the paper. Green said: "What have the most popular forms of computing done? Mostly pulled people apart, through social media, and contributed to a lot of mental health issues. And so we thought, maybe we can use computational things to bring people together." Guo added: "I became interested in our everyday environments - everyday moments between strangers - when people are physically close but socially disconnected... People may be physically together, but socially apart."
During their experiment with MirrorBot—teleoperated by Guo—twelve out of sixteen groups reported that their first meaningful contact was through the mirrors rather than direct face-to-face interaction. Additional studies compared MirrorBot with other devices such as wall-mounted mirrors or robots without mirrors; results showed that MirrorBot was most effective at facilitating eye contact and interpersonal connection.
Guo noted: "Unusual or novel objects can make people talk...but people often end up talking about the object itself... We feel MirrorBot is different because the focus is not on the robot—it's on the other human." The research team plans to present their related findings at CHI '26 from April 13-17 in Barcelona.
