20220244532 | FACIAL EXPRESSIONS FROM EYE-TRACKING CAMERAS - Systems and methods for synthesizing an image of the face by a head-mounted display (HMD), such as an augmented reality device, are disclosed. The HMD may be able to observe only a portion of the face with an inward-facing imaging system, e.g., the periocular region. The systems and methods described herein can generate a mapping of a conformation of the portion of the face that is not imaged based at least partly on a conformation of the portion of the face that is imaged. The HMD can receive an image of a portion of the face and use the mapping to determine a conformation of the portion of the face that is not observed. The HMD can combine the observed and unobserved portions to synthesize a full face image. | 2022-08-04 |
20220244533 | POLARIZATION ROTATOR FOR HEAD-UP DISPLAY - A head up display arrangement for a motor vehicle includes a head up display module having a picture generation unit emitting a light field. A plurality of linear polarizers are arranged in a stack. A first of the linear polarizers receives the light field from the picture generation unit. A last of the linear polarizers emits the light field. A windshield reflects the light field from the last linear polarizer such that the reflected light field is visible to a human driver of the motor vehicle as a virtual image. | 2022-08-04 |
20220244534 | HEADS-UP DISPLAY UNIT WITH INTEGRATED PROTECTION SYSTEM - A heads-up display apparatus that includes integrated protection structures is disclosed. The various structures protect the electronics in the heads-up display unit from liquid spills and small objects. The various protective structures are integrated into the heads-up display casing. Namely, the casing may include several drainage structures that channel liquid away from sensitive electronic components in the heads-up display unit. As a result, the heads-up display may be advantageously protected from damage when in use in a motor vehicle dashboard. | 2022-08-04 |
20220244535 | MULTI-PLANE PROJECTION WITH LASER BEAM SCANNING IN AUGMENTED REALITY DISPLAYS - An image projection system includes a first transmitter configured to generate first light beams; a first collimation lens configured to receive the first light beams and generate first collimated light beams to be projected onto an eye to render a first projection image perceived at a first projection plane; a second transmitter configured to generate second light beams; a second collimation lens configured to receive the second light beams and generate second collimated light beams to be projected onto the eye to render a second projection image perceived at a second projection plane; a first beam combiner configured to transmit the first and the second collimated light beams on a combined transmission path; and a scanner configured to steer the first and the second collimated light beams according to a scanning pattern to render the first projection image and the second projection image onto the eye. | 2022-08-04 |
20220244536 | METHOD, ELECTRONIC DEVICE, AND COMPUTER PROGRAM PRODUCT FOR DISPLAYING GRAPHIC INTERFACES - A method, an electronic device, and a computer program product for displaying graphic interfaces are provided in embodiments of the present disclosure. The method includes: generating a first graphic interface associated with an operation performed by a user of a wearable device at a computing device connected to the wearable device; causing a display device of the computing device to display the first graphic interface; and causing the wearable device to display at least a second graphic interface, the second graphic interface being obtained by extending the first graphic interface. In this way, a plurality of graphic interfaces can be efficiently displayed with both a physical display device and a wearable device. | 2022-08-04 |
20220244537 | OPTICAL ASSEMBLY AND HEAD-MOUNTED APPARATUS - An optical assembly includes a prism having a cubical structure, and first, second, third, and fourth imaging devices arranged symmetrically with the prism as a center and each including a lens. The lenses of the first, second, third, and fourth imaging devices are arranged at four sides of the prism, respectively. The optical assembly further includes an image display. The image display outputs light to the first imaging device. The prism performs optical path conversion on the light after the light passes through the lens of the first imaging device, so that the light is output after passing through the lenses of the second, third, and fourth imaging devices. | 2022-08-04 |
