Abstract:
1. A method comprising: a light projector projecting a pattern of light onto an eye, wherein the pattern comprises at least one line; receiving data regarding a first deformation of the at least one line of the pattern at a first time, wherein the first deformation of the at least one line comprises the line bowing outward when projected over the sclera or the line bowing inward when projected over the iris; receiving data regarding a second deformation of the at least one line of the pattern at a second time that is subsequent to the first time, wherein the second deformation of the at least one line of the pattern comprises the line bowing outward relative to the first deformation of the at least one line or the line bowing inward relative to the first deformation of the at least one line; and correlating the data to at least one of iris, sclera, and pupil orientation to determine a position of the eye.
