Patent number: 10387711Abstract: An electronic device includes a cover glass having a display surface, a pixelated photoemitting element array, and a pixelated photodetecting element array. The pixelated photoemitting element array emits a light signal through the cover glass to the display surface. The pixelated photodetecting element array is positioned relative to the pixelated photoemitting element array and the cover glass to receive a reflected light signal. The reflected light signal includes a portion of the emitted light signal reflected by total internal reflection from a refractive boundary at the display surface. Operation of each pixel is switched between the one or more photodetecting elements and the one or more photoemitting elements by the pixel selector signal component received from the pixel selector signal bus. A sensing trigger is configured to trigger the imaging scan by the pixelated photoemitting element array and the pixelated photodetecting element array, responsive to detection of an initiating action.Type: GrantFiled: July 27, 2016Date of Patent: August 20, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Jiandong Huang, Timothy Andrew Large, Liying Chen, Steven Nabil Bathiche

Patent number: 10082669Abstract: This document describes various techniques for implementing a variable-depth stereoscopic display. A first distance at which a viewer is disposed relative to a stereoscopic display is received. Once received, a second distance by which to change a front focal distance of a lens structure of the stereoscopic display is determined based on the first distance. The front focal distance of the lens structure is then caused to change by the second distance effective to display a stereoscopic image at the first distance.Type: GrantFiled: February 19, 2016Date of Patent: September 25, 2018Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventor: Timothy Andrew Large

Patent number: 10001845Abstract: A 3D silhouette sensing system is described which comprises a stereo camera and a light source. In an embodiment, a 3D sensing module triggers the capture of pairs of images by the stereo camera at the same time that the light source illuminates the scene. A series of pairs of images may be captured at a predefined frame rate. Each pair of images is then analyzed to track both a retroreflector in the scene, which can be moved relative to the stereo camera, and an object which is between the retroreflector and the stereo camera and therefore partially occludes the retroreflector. In processing the image pairs, silhouettes are extracted for each of the retroreflector and the object and these are used to generate a 3D contour for each of the retroreflector and object.Type: GrantFiled: June 14, 2017Date of Patent: June 19, 2018Assignee: Microsoft Technology Licensing, LLCInventors: David Kim, Shahram Izadi, Vivek Pradeep, Steven Bathiche, Timothy Andrew Large, Karlton David Powell

Patent number: 9798064Abstract: This document describes techniques and apparatuses for implementing a hybrid concentrator for a backlight. The backlight includes a light guide and multiple light sources positioned along an input end of the light guide. The backlight further includes multiple hybrid concentrators that each include a lens in a central region of the concentrator and one or more total-internal-reflection (TIR) zones. Each hybrid concentrator is positioned between a corresponding light source and the light guide, and is configured to concentrate light into the light guide. The light guide then projects the concentrated light to illuminate a modulating display panel to form images for viewing.Type: GrantFiled: March 30, 2016Date of Patent: October 24, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Karlton D.

Patent number: 9612739Abstract: This document describes embodiments of a low-latency touch-input device. The low-latency touch-input device receives writing as input to the device and temporarily displays the writing on a physical layer that overlays a touchscreen display of the device. The writing is displayed instantaneously on the physical layer before the touch-input device processes the input. The low-latency touch-input device then processes the input to generate a digital representation of the writing and renders the digital representation of the writing on the touchscreen display to replace the writing displayed on the physical layer.Type: GrantFiled: February 2, 2012Date of Patent: April 4, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Timothy Andrew Large, Steven Nabil Bathiche, Paul Henry Dietz, Bernard K.
