Résumé : | Objective: To assess the accuracy and stability of the Synapsys VNG Ulmer calibration system when the goggles and infrared camera are repositioned, and the accuracy of the equipment's geometric calibration system. Design: Prospective data collection involved participants conducting the system's horizontal calibration test. Eye measurements were then recorded for a 60° deviation (looking from 30° right to − 30° left) and repeated after the goggles and infrared camera were removed/repositioned. Participants eye measurements were also recorded after the geometric calibration had been activated. Study sample: Twenty-two participants with no history of visual or vestibular pathology were recruited for this study. Results: No significant differences were found when the goggles were removed and replaced (p = 0.21); when the infrared camera was repositioned within the goggles (p = 0.50); or when the goggles were removed and the camera repositioned (p = 0.18) after horizontal calibration. A significant difference was found during the assessment of geometric calibration (p |
