Usability of gaze-transfer in collaborative programming: How and when could it work, and some implications for research agenda

Dual eye-tracking is becoming popular in CSCW community as a method to investigate and support collaboration and interaction. Based on our preliminary study and subjective feedback of the participants, we reflect on the usability and possibilities of synchronous gaze transfer during collaborative programming. We focus on a discussion of when gaze-cursor is beneficial and what forms it could take, and on some challenges and lessons learned when implementing gaze transfer. Our results inform about the research and design of future gaze-contingent collaborative interfaces.
