Title (EN) EYE-TRACKING WITH MEMS SCANNING AND REFLECTED LIGHT
(FR) SUIVI DE L’ŒIL AU MOYEN D'UN BALAYAGE MEMS ET D'UNE LUMIÈRE RÉFLÉCHIE
Abstract:
(EN) An eye-tracking system is provided. The system includes an at least partially transparent visible light waveguide having a visible light display region configured to emit visible light to impinge upon an eye of a user. A light source is configured to emit at least infrared (IR) light that travels along an IR light path to impinge on the eye. A microelectromechanical system (MEMS) scanning mirror positioned in the IR light path is configured to direct the IR light along the IR light path. A relay positioned in the IR light path downstream of the MEMS scanning mirror includes at least one mirror configured to reflect the IR light along the IR light path. At least one sensor is configured to receive the IR light after being reflected by the eye.
(FR) La présente invention concerne un système de suivi de l’œil. Le système comprend un guide d'ondes de lumière visible au moins partiellement transparent ayant une région d'affichage de lumière visible configurée pour émettre une lumière visible qui frappe l'œil d'un utilisateur. Une source de lumière est configurée pour émettre au moins une lumière infrarouge (IR) qui se déplace le long d'un trajet de lumière IR pour frapper l’œil. Un miroir de balayage de système micro-électromécanique (MEMS) positionné dans le trajet de lumière IR est configuré pour diriger la lumière IR le long du trajet de lumière IR. Un relais positionné dans le trajet de lumière IR en aval du miroir de balayage MEMS comprend au moins un miroir configuré pour réfléchir la lumière IR le long du trajet de lumière IR. Au moins un capteur est configuré pour recevoir la lumière IR après avoir été réfléchie par l’œil.
