  • Patent number: 12265221
    Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.

  • Patent number: 12264803
    Abstract: In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a spatial light modulator, which modulates the light to project an image.

  • Patent number: 12260476
    Abstract: A display system comprises a wearable display device for displaying augmented reality content. The display device comprises a display area comprising light redirecting features that are configured to direct light to a user. The display area is at least partially transparent and is configured to provide a view of an ambient environment through the display area. The display device is configured to determine that a reflection of the user is within the user's field of view through the display area. After making this determination, augmented reality content is displayed in the display area with the augmented reality content augmenting the user's view of the reflection. In some embodiments, the augmented reality content may overlie on the user's view of the reflection, thereby allowing all or portions of the reflection to appear to be modified to provide a realistic view of the user with various modifications made to their appearance.

  • Patent number: 12254141
    Abstract: The invention relates generally to a user interaction system having a head unit for a user to wear and a totem that the user holds in their hand and determines the location of a virtual object that is seen by the user. A fusion routine generates a fused location of the totem in a world frame based on a combination of an EM wave and a totem IMU data. The fused pose may drift over time due to the sensor's model mismatch. An unfused pose determination modeler routinely establishes an unfused pose of the totem relative to the world frame. A drift is declared when a difference between the fused pose and the unfused pose is more than a predetermined maximum distance.

  • Patent number: 12249024
    Abstract: Examples of the disclosure describe systems and methods for presenting virtual content on a wearable head device. In some embodiments, a state of a wearable head device is determined by minimizing a total error based on a reduced weight associated with a reprojection error. A view reflecting the determined state of the wearable head device is presented via a display of the wearable head device. In some embodiments, a wearable head device calculates a preintegration term based on the image data received via a sensor of the wearable head device and the inertial data received via a first IMU and a second IMU of the wearable head device. The wearable head device estimates a position of the device based on the preintegration term, and the wearable head device presents the virtual content based on the position of the device.

The metasurface is a multilevel (e.g., bi-level) structure having a first level defined by spaced apart protrusions formed of a first optically transmissive material and a second optically transmissive material between the protrusions. The metasurface also includes a second level formed by the second optically transmissive material. The protrusions on the first level may be patterned by nanoimprinting the first optically transmissive material, and the second optically transmissive material may be deposited over and between the patterned protrusions. The widths of the protrusions and the spacing between the protrusions may be selected to diffract light, and a pitch of the protrusions may be 10-600 nm.

  • Publication number: 20250076973
    Abstract: Wearable systems and method for operation thereof incorporating headset and controller localization using headset cameras and controller fiducials are disclosed. A wearable system may include a headset and a controller. The wearable system may alternate between performing headset tracking and performing controller tracking by repeatedly capturing images using a headset camera of the headset during headset tracking frames and controller tracking frames. The wearable system may cause the headset camera to capture a first exposure image an exposure above a threshold and cause the headset camera to capture a second exposure image having an exposure below the threshold. The wearable system may determine a fiducial interval during which fiducials of the controller are to flash at a fiducial frequency and a fiducial period. The wearable system may cause the fiducials to flash during the fiducial interval in accordance with the fiducial frequency and the fiducial period.
