Abstract: A computing device is provided, which includes an input device, a display device, and a processor configured to, at a rendering stage of a rendering pipeline, render visual scene data to a frame buffer, and generate a signed distance field of edges of vector graphic data, and, at a reprojection stage of the rendering pipeline prior to displaying the rendered visual scene, receive post rendering user input via the input device that updates the user perspective, reproject the rendered visual scene data in the frame buffer based on the updated user perspective, reproject data of the signed distance field based on an updated user perspective, evaluate the signed distance field to generate reprojected vector graphic data, and generate a composite image including the reprojected rendered visual scene data and the reprojected graphic data, and display the composite image on the display device.

Abstract: A three-dimensional (3D) object is configured for presentation on a display screen. Object data representing a model of a 3D object is received at a graphics processing unit. The object data includes a plurality of interrelated polygons. Coordinates for one or more clipping boundaries are also received at the graphics processing unit. The clipping boundaries definer a presentation region that overlaps at least in part with visible portions of the display screen. Using a geometry shader, per-polygon clipping is performed on each polygon of the object data that intersects with at least one clipping boundary. Only portions of the 3D object that lie within the presentation region are then presented on the display screen.

Abstract: Examples are disclosed herein that relate to a six degree-of-freedom (DOF) input device. An example provides an input device comprising a body, a sensor system configured to sense motion of the input device with six DOF, a communication interface and a controller. The controller is configured to transmit output based on sensor data from the sensor system for use in controlling an application in a first mode in which each of the six degrees-of-freedom is used as input, the application being controlled in the first mode in response to detecting a first condition, and transmit output based on sensor data from the sensor system for use in controlling the application in a second mode in which one or more of the six degrees-of-freedom is not used as input, the application being controlled in the second mode in response to detecting a second condition.

Abstract: Contemporary human-computer interactions include conversational interactions, wherein devices present conversational prompts (e.g., generated speech) and conversational responses to user inquiries (e.g., verbal user input). Presented herein are techniques for automatically assembling conversational representations of web content. A variety of automated assembly techniques are disclosed, such as conversational template for websites of various website types. Interactions of users with a website may be monitored to identify actions that the users frequently perform, and conversational interactions may be generated that correspond to the actions. A web service may present a set of requests, and conversational interactions may be assembled to match the respective requests and responses of the web service. Conversational interactions may include transitions between websites, and conversational representations may be merged to integrate content from multiple websites.

Abstract: Tracking a user head position detects a change to a new head position and, in response, a remote camera is instructed to move to a next camera position. A camera image frame, having an indication of camera position, is received from the camera. Upon the camera position not aligning with the next camera position, an assembled image frame is formed, using image data from past views, and rendered to appear to the user as if the camera moved in 1:1 alignment with the user's head to the next camera position.

Abstract: The subject disclosure pertains to systems and methods for storing and maintaining a large volume of data in a hierarchical data structure. In particular, geographical data can be stored in the hierarchical data structure to facilitate location and retrieval of data. In addition, system and methods for retrieving data from the hierarchical data structure are provided. Search queries can specify both the point of origin of the search and a search method or strategy for navigating the hierarchical data structure. In one aspect, the hierarchical data structure can provide for maintaining sibling relationships.
