Augmented Reality has been utilized for surgical training. During the implementation, displaying instructional information at the right moment is critical for skill acquisition. We built a new surgical training platform combining augmented reality system (HoloLens, Microsoft) with an eye-tracker (Pupil labs, Germany). Our goal is to detect the moments of performance difficulty using the integrated eye-tracker so that the system could display instructions at the precise moment when the user is seeking instructional information during a surgical skill practice in simulation. In the paper, we describe the system design, system calibration and data transferring between these devices.
