Patent number: 11347051Abstract: 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.Type: GrantFiled: July 30, 2020Date of Patent: May 31, 2022Assignee: Magic Leap, Inc.Inventors: Alexander Ilic, Martin Georg Zahnert

Patent number: 11290706Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.Type: GrantFiled: December 17, 2020Date of Patent: March 29, 2022Assignee: Magic Leap, Inc.Inventors: Lionel Ernest Edwin, Zachary C.
