Abstract
In an unobtrusive visual axis enrollment process, a line of text or other content is displayed at a known vertical location and virtual depth that the user can then read. This line of text may be content that the user needs to read as part of the normal enrollment process. As the user reads the line of text, eye tracking cameras may capture images of the eye. This data may then be used to estimate a stimulus plane. The error between the estimated stimulus plane and the ground truth stimulus plane (the actual location of the line of text in virtual space) may then be used to estimate the kappa angle.
