Abstract
A disclosed computer-implemented method may include directing a display device included in a head-mounted display worn by a user to illuminate, via a projection of a line at an illumination time, a portion of a cornea of the user. The method may further include detecting, via an image sensor at a detection time, a portion of the projection of the line reflected by the portion of the cornea of the user and identifying a distortion of the projection of the line reflected by the portion of the cornea of the user. The method may also include determining a shape of the cornea of the user based on the illumination time, the detection time, and the distortion of the projection of the line reflected by the portion of the cornea. Various other methods, systems, apparatuses, and computer-readable media are also disclosed.
