Communication through pupillometry
Video of our system for pupil-based communication (see: Stoll, J., Chatelle, C., Carter, O., Koch, C., Laureys, S., & Einhäuser, W. (2013). Current Biology, 23(15), R647-R648.)
Top left : Experimental setup, computer screen is visible to the far right. Top right: Stimulus as seen by the patient. Bottom left: Online analysis of pupil size. Rechts unten: Operator's screen with view of pupil. Audio: The question is read by the experimenter (“Is your name Josef?”); after 5s the system provides the answer "non" ("no") and further 5s later "oui" ("yes") (which is correct in this case).
Real-world eye movements
