Publication number: 20230036102Abstract: Methods and systems for improved preparing of received data using differential diagnosis for analysis by machine learning models. In one embodiment, a method is provided that includes receiving an identifier of an event. A plurality of inquiries may be sequentially processed, and subsequent inquiries for processing may be selected based on the responses to earlier inquiries. A tensor may be used to store indications of which inquiries were processed and the responses received to the inquiries. A machine learning model may use the tensor to determine a diagnosis and whether the event is an emergency event requiring intervention. If the event is an emergency event, an intervention may be generated for the emergency event, which may include a computer system taking automatic action to respond to the emergency event.Type: ApplicationFiled: July 30, 2021Publication date: February 2, 2023Inventor: Douglas Graeme Brown

Patent number: 10134192Abstract: Methods and systems for displaying a computer generated image corresponding to the pose of a real-world object in a mixed reality system. The system may include of a head-mounted display (HMD) device, a magnetic track system and an optical system. Pose data detected by the two tracking systems can be synchronized by a timestamp that is embedded in an electromagnetic field transmitted by the magnetic tracking system. A processor may also be configured to calculate a future pose of the real world object based on a time offset based on the time needed by the HMD to calculate, buffer and generate display output and on data from the two tracking systems, such that the relative location of the computer generated image (CGI) corresponds with the actual location of the real-world object relative to the real world environment at the time the CGI actually appears in the display.Type: GrantFiled: October 17, 2016Date of Patent: November 20, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Arthur Tomlin, Adam Gabriel Poulos, Cameron Graeme Brown

Publication number: 20180315250Abstract: Motion and/or rotation of an input mechanism can be tracked and/or analyzed to determine limits on a user's range of motion and/or a user's range of rotation in three-dimensional space. The user's range of motion and/or the user's range of rotation in three-dimensional space may be limited by a personal restriction for the user (e.g., a broken arm). The user's range of motion and/or the user's range of rotation in three-dimensional space may additionally or alternatively be limited by an environmental restriction (e.g., a physical object in a room). Accordingly, the techniques described herein can take steps to accommodate the personal restriction and/or the environmental restriction thereby optimizing user interactions involving the input mechanism and a virtual object.Type: ApplicationFiled: July 5, 2018Publication date: November 1, 2018Inventors: Adam Gabriel POULOS, Cameron Graeme BROWN, Andrew Austin JACKSON, Cheyne Rory Quinn MATHEY-OWENS, Michael Robert THOMAS, Arthur TOMLIN

Patent number: 10068376Abstract: Examples are disclosed herein that relate to the display of mixed reality imagery. One example provides a mixed reality computing device comprising an image sensor, a display device, a storage device comprising instructions, and a processor. The instructions are executable to receive an image of a physical environment, store the image, render a three-dimensional virtual model, form a mixed reality thumbnail image by compositing a view of the three-dimensional virtual model and the image, and display the mixed reality thumbnail image. The instructions are further executable to receive a user input updating the three-dimensional virtual model, render the updated three-dimensional virtual model, update the mixed reality thumbnail image by compositing a view of the updated three-dimensional virtual model and the image of the physical environment, and display the mixed reality thumbnail image including the updated three-dimensional virtual model composited with the image of the physical environment.Type: GrantFiled: January 11, 2016Date of Patent: September 4, 2018Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Jeff Smith, Cameron Graeme Brown, Marcus Ghaly, Andrei A.

Patent number: 9952656Abstract: Disclosed are a method and corresponding apparatus to enable a user of a display system to manipulate holographic objects. Multiple holographic user interface objects capable of being independently manipulated by a user are displayed to the user, overlaid on a real-world view of a 3D physical space in which the user is located. In response to a first user action, the holographic user interface objects are made to appear to be combined into a holographic container object that appears at a first location in the 3D physical space. In response to the first user action or a second user action, the holographic container object is made to appear to relocate to a second location in the 3D physical space. The holographic user interface objects are then made to appear to deploy from the holographic container object when the holographic container object appears to be located at the second location.Type: GrantFiled: August 21, 2015Date of Patent: April 24, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Adam Gabriel Poulos, Cameron Graeme Brown, Aaron Daniel Krauss, Marcus Ghaly, Michael Thomas, Jonathan Paulovich, Daniel Joseph McCulloch
