Publication number: 20170345217Abstract: Methods for generating and displaying images associated with one or more virtual objects within an augmented reality environment at a frame rate that is greater than a rendering frame rate are described. The rendering frame rate may correspond with the minimum time to render images associated with a pose of a head-mounted display device (HMD). In some embodiments, the HMD may determine a predicted pose associated with a future position and orientation of the HMD, generate a pre-rendered image based on the predicted pose, determine an updated pose associated with the HMD subsequent to generating the pre-rendered image, generate an updated image based on the updated pose and the pre-rendered image, and display the updated image on the HMD. The updated image may be generated via a homographic transformation and/or a pixel offset adjustment of the pre-rendered image by circuitry within the display.Type: ApplicationFiled: July 28, 2017Publication date: November 30, 2017Applicant: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Calvin Chan, Jeffrey Neil Margolis, Andrew Pearson, Martin Shetter, Ashraf Ayman Michail, Barry Corlett

Publication number: 20170177082Abstract: Embodiments are described herein for determining a stabilization plane to reduce errors that occur when a homographic transformation is applied to a scene including 3D geometry and/or multiple non-coplanar planes. Such embodiments can be used, e.g., when displaying an image on a head mounted display (HMD) device, but are not limited thereto. In an embodiment, a rendered image is generated, a gaze location of a user is determined, and a stabilization plane, associated with a homographic transformation, is determined based on the determined gaze location. This can involve determining, based on the user's gaze location, variables of the homographic transformation that define the stabilization plane. The homographic transformation is applied to the rendered image to thereby generate an updated image, and at least a portion of the updated image is then displayed.Type: ApplicationFiled: March 9, 2017Publication date: June 22, 2017Applicant: Microsoft Technology Licensing, LLCInventors: Ashraf Ayman Michail, Roger Sebastian Kevin Sylvan, Quentin Simon Charles Miller, Alex Aben-Athar Kipman

Publication number: 20160299567Abstract: One embodiment provides a method to display video such as computer-rendered animation or other video. The method includes assembling a sequence of video frames featuring a moving object, each video frame including a plurality of subframes sequenced for display according to a schedule. The method also includes determining a vector-valued differential velocity of the moving object relative to a head of an observer of the video. At a time scheduled for display of a first subframe of a given frame, first-subframe image content transformed by a first transform is displayed. At a time scheduled for display of the second subframe of the given frame, second-subframe image content transformed by a second transform is displayed. The first and second transforms are computed based on the vector-valued differential velocity to mitigate artifacts.Type: ApplicationFiled: April 9, 2015Publication date: October 13, 2016Inventors: Matthew Calbraith Crisler, Robert Thomas Held, Stephen Latta, Ashraf Ayman Michail, Martin Shetter, Arthur Tomlin

Publication number: 20130139072Abstract: The present invention extends to methods, systems, and computer program products for enabling the development and execution of applications that employ a composited application model. A composited application includes components that are to be executed in different runtimes. Accordingly, an application developer can leverage different runtimes within a single application. A managing runtime is used to manage the various runtimes used by a composited application. The managing runtime performs input redirection to route user input to the appropriate runtime and output compositing to composite each runtime's user interface components into a single seamless scene.Type: ApplicationFiled: November 28, 2011Publication date: May 30, 2013Applicant: MICROSOFT CORPORATIONInventors: Akhilesh Kaza, Ashraf Ayman Michail, Paul Lawrence Bleisch, Istvan Cseri, Alan Chun Tung Liu
