Publication number: 20220187907Abstract: This disclosure relates to displaying a user interface for a computing device based upon a user intent determined via a spatial intent model. One example provides a computing device comprising a see-through display, a logic subsystem, and a storage subsystem. The storage subsystem comprises instructions executable by the logic machine to receive, via an eye-tracking sensor, eye tracking samples each corresponding to a gaze direction of a user, based at least on the eye tracking samples, determine a time-dependent attention value for a location in a field of view of the see-through display, based at least on the time-dependent attention value for the location, determine an intent of the user to interact with a user interface associated with the location that is at least partially hidden from a current view, and in response to determining the intent, display via the see-through display the user interface.Type: ApplicationFiled: December 11, 2020Publication date: June 16, 2022Applicant: Microsoft Technology Licensing, LLCInventors: Austin S. LEE, Anthony James AMBRUS, Sheng Kai TANG, Keiichi MATSUDA, Aleksandar JOSIC

Publication number: 20210169581Abstract: A surgical system including a XR headset, a tracking system, and an XR headset controller. The XR headset can be worn by a user during a surgical procedure and includes a see-through display screen configured to display a world-registered XR image and to allow at least a portion of a real-world scene to pass therethrough for viewing by the user. The tracking system can determine a real-world pose of the XR headset and a real-world pose of a real-world element. The real-world pose of the XR headset and the real-world pose of the real-world element being determined relative to a real-world coordinate system. The XR headset controller can generate the world-registered XR image based on the real-world pose of the XR headset and the real-world pose of the real-world element. The world-registered XR image includes a virtual element that is generated based on a characteristic of the real-world element.Type: ApplicationFiled: February 4, 2020Publication date: June 10, 2021Inventors: Thomas Calloway, Isaac Dulin, Keiichi Matsuda, Christine Russ, Keerthighaan Kanagasegar, Amelia Raphaelson

Publication number: 20210169605Abstract: A surgical robot positions an end effector that guides movement of a surgical tool during a surgical procedure on a patient anatomical structure. A tracking system determines a pose of the anatomical structure and a pose of the end effector and/or the surgical tool. A navigation controller determines a target pose for the surgical tool based on a surgical plan and based on the pose of the anatomical structure, and generates steering information based on the target pose for the surgical tool, the pose of the anatomical structure, and the pose of the surgical tool and/or the end effector. The steering information indicates where the surgical tool and/or the end effector need to be moved. An AR headset controller receives the steering information from the navigation controller and displays a graphical representation of the steering information and/or the target pose for the surgical tool on a see-through display screen.Type: ApplicationFiled: December 10, 2019Publication date: June 10, 2021Inventors: Thomas Calloway, Weston Healy, Isaac Dulin, Dale Earle, Keiichi Matsuda, Norbert Johnson, Bessam Al Jewad, Christine Russ, Michael Robinson, Keerthighaan Kanagasegar

Publication number: 20210169578Abstract: A surgical system includes an AR headset and a AR headset controller. The AR headset is configured to be worn by a user during a surgical procedure and has a see-through display screen configured to display an AR image and to allow at least a portion of a real-world scene to pass therethrough for viewing by the user. The AR headset also includes an opacity filter positioned between at least one of the user's eyes and the real-world scene when the see-through display screen is viewed by the user. The opacity filter provides opaqueness to light from the real-world scene. The AR headset controller communicates with a navigation controller to receive navigation information from the navigation controller which provides guidance to the user during the surgical procedure on an anatomical structure, and generates the AR image based on the navigation information for display on the see-through display screen.Type: ApplicationFiled: December 10, 2019Publication date: June 10, 2021Inventors: Thomas Calloway, Weston Healy, Isaac Dulin, Dale Earle, Keiichi Matsuda
