Title (EN) PRISM-BASED EYE TRACKING
(FR) POURSUITE OCULAIRE BASÉE SUR UN PRISME
Abstract:
(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.
(FR) L'invention concerne un dispositif visiocasque (HMD) (100, 300) qui comprend un panneau d'affichage (102, 308, 310) et un séparateur de faisceau à prisme en X (104) disposé le long d'un premier axe (202) entre le panneau d'affichage et une position attendue d'un œil (112). Le séparateur de faisceau à prisme en X dirige un premier faisceau lumineux (212) dans une première direction du panneau d'affichage vers l'œil le long du premier axe, dirige un deuxième faisceau lumineux (216) dans une seconde direction le long d'un second axe (208) sensiblement perpendiculaire au premier axe, et dirige un troisième faisceau lumineux (222) dans la seconde direction le long du second axe, le deuxième faisceau lumineux étant représentatif du premier faisceau lumineux et le troisième faisceau lumineux étant représentatif d'une réflexion du premier faisceau lumineux sur l'œil. Le dispositif HMD comprend en outre un appareil de prise de vues d'imagerie (106) pour capturer une image composite (232) comprenant une combinaison à la fois d'une représentation du deuxième faisceau lumineux et d'une représentation du troisième faisceau lumineux.
