Abstract
Capturing Purkinje images is essential for wide-range and accurate eye-tracking. The range of eye rotation over which the Purkinje image is observable has so far been modeled by a cone shape called a gaze cone. In this study, we extended the gaze cone model to include occlusion by an eyelid. First, we developed a measurement device that has eight spider-like arms. Then, we proposed a novel model that considers eyeball movement. Using the device, we measured the range of corneal reflection, and we fitted the proposed model to the results.
