Visual Attention Analysis–The Power of Shared Gaze
Multi-subject eyetracking—simultaneously recording the gaze of two or more individuals—unlocks new dimensions in studying social interaction, joint attention, and collaborative behavior. Traditional single-subject setups limit insights to individual gaze patterns, but dual or multi-subject systems reveal how people coordinate attention in real time, a critical factor in fields like piloting, human-robot collaboration (HRC), education, sports, psychology, and healthcare.
For example, research highlights the importance of mutual gaze (when two people look at each other) and shared gaze (when both focus on the same object) in early social development and task coordination. These metrics, only measurable with multi-subject setups, enable researchers to quantify how gaze synchrony shapes communication, learning, and teamwork.
Achieving visual attention analysis for multiple subjects on a technical level requires a flexible & lossless recording framework handling scalable data flows without interference, delay, or other network- or computing-power-related restraints. Once an extremely complex method requiring manual synchronization and enormous hardware setups, Ergoneers’ Prophea.X has optimized this process, unlocking new dimensions in the study of social interaction, joint attention, and collaborative behavior.
