Depth plane selection for multi-depth plane display systems by user categorization

A display system includes a head-mounted display configured to project light, having different amounts of wavefront divergence, to an eye of a user to display virtual image content appearing to be disposed at different depth planes. The wavefront divergence may be changed in discrete steps, with the change in steps being triggered based upon whether the user is fixating on a particular depth plane. The display system may be calibrated for switching depth planes for a main user. Upon determining that a guest user is utilizing the system, rather than undergoing a full calibration, the display system may be configured to switch depth planes based on a rough determination of the virtual content that the user is looking at. The virtual content has an associated depth plane and the display system may be configured to switch to the depth plane of that virtual content.

20220334405 · 2022-10-20 ·

Embodiments relate to an apparatus, method, and computer program for a volumetric display apparatus in a vehicle. The apparatus includes a display in the distal end and an enclosure for the rod with a mirrored interior and an aperture adapted to receive the rod's distal end. The rod and the enclosure are centered on a longitudinal axis passing through the interior. The rod is adjustable along the longitudinal axis of the enclosure from a closed position immediately adjacent to the aperture to an open position that extends from the closed position to the proximal end of the enclosure. A holographic image is formed at the aperture of the enclosure when a plurality of light vectors emitted from the image on the display are reflected off the mirrored surface of the interior while the rod is in the open position.

See-through computer display systems

An apparatus includes an eye cover adapted to be removably mounted on a head-worn computer with a see-through computer display and a flexible audio headset mounted to the eye cover. The flexible audio headset is mounted to the eye cover with a magnetic connection.

See-through computer display systems

Embodiments include a head-worn display including a display panel sized and positioned to produce a field of view to present digital content to an eye of a user, and a processor adapted to present the digital content to the display panel such that the digital content is only presented in a portion of the field of view, the portion being in the middle of the field of view such that horizontally opposing edges of the field of view are blank areas. The processor is adapted to shift the digital content into one of the blank areas to adjust the convergence distance of the digital content and thereby change the perceived distance from the user to the digital content.

Method and system for eye tracking with glint space recalibration on wearable heads-up display
11619992 · 2023-04-04 · ·

A method of tracking an eye of a user includes generating an infrared light, scanning the infrared light over the eye, and detecting reflections of the infrared light from the eye over an eye tracking period. A plurality of glints is identified from the reflections of the infrared light detected. A glint center position of each glint in a glint space is determined and transformed to a gaze position in a display space. At least once during the eye tracking period, an image of the eye is reconstructed from a portion of the reflections of the infrared light detected. A pupil is detected from the image, and a pupil center position is determined. A glint-pupil vector is determined from the pupil center position and the glint center position of at least one glint corresponding in space to the pupil. The glint space is recalibrated based on the glint-pupil vector.
