Operator Body-mounted Heads-up Display (e.g., Helmet Mounted Display) Patents (Class 345/8)
  • Patent number: 11927761
    Abstract: A head-mounted device may have a head-mounted housing. The head-mounted housing may have rear-facing display that displays a three-dimensional image to rear eye boxes. The head-mounted device may also have a front-facing display that faces away from the rear eye boxes. The front-facing display may cover a front face of the head-mounted housing. To share content such as content being displayed by the rear-facing displays with external viewers, the head-mounted device may use the front-facing display or a separate display to display images. An accessory that is coupled to the front face of the housing may reflect an image on the front-facing display towards a viewer for viewing. Sensors in the device may detect presence of the accessory. Display projectors and waveguides or optical layers on the front face that overlap the front-facing display may be used to display three-dimensional images to front eye boxes.

  • Patent number: 11833901
    Abstract: A method includes placing a physical target on a windshield of a vehicle, mounting a fixture inside the vehicle to position a camera array on the fixture within a line of sight of a passenger, capturing images of the physical target using the camera array, and determining a difference between actual and target locations of the physical target in each image. In addition, the method includes controlling the HUD to display a virtual target on the windshield, capturing images of the virtual target using the camera array, and determining a target location of the virtual target in each image based on the difference. Further, the method includes determining an offset between an actual location of the virtual target in each image and the target location of the virtual target in each image, and adjusting the location of an image projected onto the windshield by the HUD based on the offset.

  • Patent number: 11835722
    Abstract: A display device includes an optical assembly and a display that includes a front surface and a back surface. The display is configured to output image light from the front surface and transmit ambient light from the back surface to the front surface. The optical assembly includes a substrate that has a substantially uniform thickness, a beam splitter, and a reflector. The optical assembly is configured to receive the image light output from the front surface of the display and to transmit a portion of the image light at a first non-zero optical power via an optical path that includes reflections at the reflector and at the beam splitter. The optical assembly is also configured to transmit a portion of the ambient light through the optical assembly at a second optical power without reflection at the reflector. The second optical power is less than the first optical power.

  • Patent number: 11835727
    Abstract: An information processing apparatus according to an embodiment of the present technology includes a physical information acquisition unit, a gesture information acquisition unit, a determination condition setting unit, and a control unit. The physical information acquisition unit acquires physical information of a user wearing a head-mounted casing. The gesture information acquisition unit acquires gesture information regarding a gesture of the user. The determination condition setting unit sets, on the basis of the physical information, a determination condition for determining a trigger gesture that is a trigger for an operation input by the gesture of the user. The control unit determines, on the basis of the gesture information and the determination condition, whether or not the trigger gesture is performed and controls, on the basis of a result of the determination, an output corresponding to the trigger gesture.

  • Patent number: 11835724
    Abstract: An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity.

  • Patent number: 11815690
    Abstract: Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.

  • Patent number: 11816771
    Abstract: System and methods are provided for augmented reality displays for medical and physiological monitoring. Augmented reality user interfaces are virtually pinned to a physical device, a location, or to a patient. An augmented reality position determination process determines the presentation of user interfaces relative to reference positions and reference objects. Detection of gestures causes the augmented reality users interfaces to be updated, such as pinning a user interface to a device, location, or patient. Looking away from an augmented reality user interface causes the user interface to minimize or disappear in an augmented reality display. An augmented reality gesture detection process determines gestures based on captured image data and computer vision techniques performed on the image data.
