Turntable and eye movement recording setup. (A) The motorized three-dimensional turntable (Acutronic, Bubikon, Switzerland) showing author CJB. Subjects are comfortably padded with pillows and securely fastened to the chair with a five-point pilot harness, while the head is restrained with an individually molded thermoplastic mask. To give a further sense of security, subjects hold a hand bar, while the feet are restrained with a footrest. (B) Video goggles (EyeSeeCam, Munich, Germany), mounted under a thermoplastic mask to minimize head movements, are used to monitor and record eye movements.
