Abstract
In some embodiments, readily understandable information displays are provided to help an operator guide an eye of a subject into an eyebox of a retinal imaging system. In some embodiments, a three-dimensional position of the eye with respect to the retinal imaging system is determined, and an interface that includes a three-dimensional representation of the position of the eye with respect to the eyebox is generated. In some embodiments, the gaze direction may also be determined and presented in the interface, so that the operator can also prompt the subject to correct issues with incorrect gaze direction.
