Patent number: 12260560Abstract: Various implementations track an eye using both camera images and light sensor data, e.g., from a photosensitive surface or set of photodetectors. The camera need not capture images at a high capture rate since the light sensor data captured from the light sensor provides information about the eye during the time periods between camera frames. An eye tracking device may thus provide eye tracking with high temporal resolution using less power and resources and prior devices. The eye tracking device includes a lens (e.g., a diffractive optical element (DOE)) that splits received light onto the camera and light sensor. The camera and light sensor may be aligned, e.g., co-centered. Using such a lens to provide light to an aligned camera and light sensor facilitates tracking the eye characteristics by reducing the need for matching the data and/or accounting for multiple environmental light sources.Type: GrantFiled: March 11, 2022Date of Patent: March 25, 2025Assignee: Apple Inc.Inventors: Siddharth S. Hazra, Aleksandar M. Movshovich, Nicholas C. Soldner, Tushar Gupta

Publication number: 20250020938Abstract: A head-mounted device may include a first display having a first projector and a first waveguide, a second display having a second projector and a second waveguide, first and second cameras, an optical sensor that couples the first waveguide to the second waveguide, and position sensors mounted to the first and second cameras and the optical sensor. The optical sensor may gather image sensor data from first image light propagating in the first waveguide and second image light propagating in the second waveguide. The cameras may capture real-world images. The position sensors may gather position measurements. Control circuitry may calibrate optical misalignment in the device by adjusting the first and/or second image light based on the image sensor data, the position measurements, and/or the world light.Type: ApplicationFiled: September 30, 2024Publication date: January 16, 2025Inventors: Dominic P Cincione, Cameron A Harder, Christopher Patton, Nicholas C Soldner, Scott M DeLapp

Patent number: 12149825Abstract: A processing unit of an electronic device may transmit a synchronization pulse to each of a first plurality of motion sensors (e.g., Inertial Measurement Units or IMUs) communicatively coupled to the processing unit, wherein the synchronization pulse transmitted to each motion sensor of the first plurality of motion sensors is assigned an offset time amount by the processing unit. The processing unit then obtains motion information samples from each of the first plurality of motion sensors, e.g., in an order corresponding to the offset time amounts assigned to the respective motion sensors, and then performs a processing operation based upon the obtained motion information samples. In some embodiments, each motion sensor may be assigned an equal offset time amount. In other embodiments, the offset time amount assigned to each motion sensor may be individually determined, e.g., based on one or more conditions, settings, or preferences related to the electronic device.Type: GrantFiled: September 22, 2022Date of Patent: November 19, 2024Assignee: Apple Inc.Inventors: Nicholas C.

Publication number: 20240353440Abstract: A sensor assembly for a head-mountable device, the sensor assembly comprising: a flex circuit, an inertial measurement unit coupled to the flex circuit, an enclosure disposed around the inertial measurement unit and a portion of the flex circuit, to define a sealed volume containing the inertial measurement unit and the portion of the flex circuit. Thereby, a head-mountable device can securely support sensors in a manner that maintains their positions and orientations over time and isolates the sensors from an external environment. The sensor can be mounted within a sealed enclosure while maintaining an operable connection to the sensor. The sensor assemblies provides high robustness during the entirety of the service life of the head-mountable device without placing strain on the sensors themselves. The seal of the enclosure can isolate the sensor from external influences by preventing ingress of elements through the case and plate.Type: ApplicationFiled: August 24, 2022Publication date: October 24, 2024Inventors: Aidan N. ZIMMERMAN, Ivan S. MARIC, Nicholas C. SOLDNER, Jose A. RIOS, Stergios ROUMELIOTIS, David S. GRAGNOLATI

Publication number: 20240272435Abstract: A head-mounted device may include a component such as a sidewall structure that is switchable between an opaque mode and a transparent mode. In the opaque mode, the component may block ambient light from passing into the interior of the head-mounted device (such that the user cannot see the surrounding environment). In the transparent mode, the component may allow ambient light to pass into the interior of the head-mounted device (such that the user can see portions of the surrounding environment). The opaque mode may provide a more immersive experience for the user of the head-mounted device, whereas the transparent mode may allow the user to see objects in their surrounding physical environment. Instead or in addition, the head-mounted device may include one or more sidewall displays.Type: ApplicationFiled: September 21, 2023Publication date: August 15, 2024Inventors: Simon Fortin-Deschenes, Amanda K Abramson, Luke A Pillans, Nicholas C Soldner

Publication number: 20240210712Abstract: A head-mounted device such as a pair of glasses may have a head-mounted housing. The head-mounted device may include displays such as projector displays and may include associated optical components. The optical components may include waveguides that are used in providing images received from the displays to corresponding eye boxes for viewing by a user. Changes in the relative orientation between the displays and waveguides may warp the images in the eye boxes. To compensate for this effect, control circuitry in the head-mounted device may use position sensors to measure the relative positions of the displays and waveguides. Image warping due to misalignment between the displays and waveguides may be removed by applying compensating image warping to the images being produced by the displays.Type: ApplicationFiled: February 7, 2024Publication date: June 27, 2024Inventors: Darshan R Kasar, Christopher Patton, Dominic P Cincione, Ivan S Maric, Nicholas C Soldner

Publication number: 20230281846Abstract: Methods and apparatus for specular surface mapping in which a camera detects reflections of a light source from a specular surface. The detected light sources may be projected onto a celestial sphere as virtual point sources. True positive observations should be tightly clustered on the celestial sphere; thus, false positives may be identified and removed. Specular surface information may then be determined from clusters of the virtual point sources on the celestial sphere. The clusters of virtual point sources on the celestial sphere may be identified and used to identify a surface as a specular surface. The clusters may also be used to extract other information regarding the specular surface, including but not limited to distance to and extent of the specular surface.Type: ApplicationFiled: December 22, 2022Publication date: September 7, 2023Applicant: Apple Inc.Inventors: Luke A.
