The detection of mutual gaze in the context of human-robot interaction is crucial for the understanding of human partners' behavior. Indeed, the monitoring of the users' gaze from a long distance enables the prediction of their intention and allows the robot to be proactive. Nonetheless, current implementations struggle or cannot operate in scenarios where detection from long distances is required. In this work, we propose a ROS2 software pipeline that detects mutual gaze up to 5 m of distance. The code relies on robust off-the-shelf perception algorithms.
