Beschreibung
Zusammenfassung:	An eye tracking system for detecting position and movements of a user's eyes in a head-mounted display (HMD). The eye tracking system may include at least one near-IR (NIR) eye tracking camera positioned at each side of the user's face and pointed towards eye-facing surfaces of eyepieces of the HMD, an illumination source that emits NIR light towards the user's eyes, and hot mirrors located between the eye-facing surfaces of the eyepieces and the user's eyes. The hot mirrors reflect at least a portion of NIR light, while allowing visible light to pass. The cameras capture images of the user's eyes reflected by the hot mirrors. Positioning the hot mirrors at or near the eye-facing surfaces of the eyepieces allows the cameras to be placed at the sides of the user's face without having to image through the eyepieces.
