DESCRIPTION:Near-eye volumetric displays\, showing multiple focal planes\,
  require knowledge of the accurate position of the nodal point of the eye 
 to correctly render a 3D scene. This is because pixels seen through multip
 le planes must be accurately aligned with the eye’s visual axis to ensur
 e consistency across focal planes. While most eye-tracking methods focus o
 n determining a gaze position within a designated target space\, this work
  aims to track both the eye position and the corresponding gaze direction 
 expressed in coordinates relative to the physical location of the volumetr
 ic display planes. To achieve this\, we rely on a near-infra-red (NIR) cam
 era image of the pupil and corneal reflections (glints). The existing eye 
 model is used to establish the relationship between the pupil and glint po
 sitions in a NIR image and the eye position and rotation in a 3D space. We
  address the key challenge of robust tracking of the glints in a system th
 at introduces multiple reflections. We also demonstrate that the system re
 duces the need for recalibration on subsequent uses. Our experiments on a 
 multiple-focal plane display demonstrate that the method can maintain an a
 ccurate projection point for volumetric displays.\n\nZoom link: https://ca
