Title: (EN) Prism-based eye tracking
Abstract: front page image
(EN) An HMD device (100, 300) includes a display panel (102, 308, 310) and an x-prism beamsplitter (104) disposed along a first axis (202) between the display panel and an expected position of an eye (112). The x-prism beamsplitter directs a first light beam (212) in a first direction from the display panel to the eye along the first axis, directs a second light beam (216) in a second direction along a second axis (208) substantially perpendicular to the first axis, and directs a third light beam (222) in the second direction along the second axis, wherein the second light beam is representative of the first light beam and the third light beam is representative of a reflection of the first light beam off of the eye. The HMD device further includes an imaging camera (106) to capture a composite image (232) comprising a combination of both a representation of the second light beam and a representation of the third light beam.
