摘要： A computer-implemented system and method of configuring a path of a virtual camera. The method comprises receiving user steering information to control the path of the virtual camera in a scene; determining a primary target based upon a field of view of the virtual camera; and estimating a future path and a corresponding future field of view of the virtual camera, based on the received steering information. The method further comprises determining a secondary target of the scene proximate to the estimated future path of the virtual camera based on a preferred perspective of the secondary target; and configuring the path to capture the secondary target from the preferred perspective.

摘要： A computer-implemented system and method of rendering an object in a virtual view. The method comprises determining a variation of an occlusion measure of the object over time, the occlusion measure being an evaluation of an occlusion of the virtual view by the object, the variation of the occlusion measure determined based on a trajectory of the object. The method also comprises determining a transition effect for the object based on the variation of the occlusion measure, the transition effect being a visual effect, and applying the determined transition effect to render the object, the determined transition effect being applied according to a position of the object as the object moves along the trajectory.

摘要： A method of displaying a video sequence of a scene captured using a video capture device, the video sequence having a limited field of view of the scene. A plurality of objects positioned in the scene outside limits of the field of view of the captured video sequence is determined. A representation of at least one of the objects is generated, a characteristic of the generated representation being determined from an object impact measure defining, at least in part, a confidence that the at least one object will enter the field of view. The generated object representation is displayed together with, and proximate to, a display of the captured video sequence.

摘要： A method of rendering virtual content is disclosed. A position to render each of a first and a second portion of virtual content on an augmented reality device is determined. Each of the first and second portion of virtual content is linked to a corresponding physical document. The position for rendering each of the first and second portions of virtual content is determined according to a position of the corresponding physical documents with the position of the first portion of virtual content being adjacent to the position of the second portion of virtual content. Viewing zones for each of the first and second portions of virtual content are determined, based on the determined positions. Each of the viewing zones is defined as a physical region where an augmentation of the corresponding portion of virtual content is visible on the augmented reality device. The viewing zone of the second portion of virtual content is modified to reduce any overlap with the viewing zone of the first portion of virtual content. The first and the second portions of virtual content are rendered on the augmented reality device according to the determined viewing zones.
摘要翻译： 公开了一种渲染虚拟内容的方法。 确定在增强现实设备上呈现虚拟内容的第一部分和第二部分中的每一个的位置。 虚拟内容的第一部分和第二部分中的每一个链接到相应的物理文档。 根据虚拟内容的第一部分的位置与虚拟内容的第二部分的位置相邻的对应的物理文档的位置，确定用于渲染虚拟内容的第一和第二部分中的每一个的位置。 基于确定的位置确定虚拟内容的第一和第二部分中的每一个的观看区域。 每个观看区域被定义为虚拟内容的相应部分的增加在增强现实设备上可见的物理区域。 虚拟内容的第二部分的观看区域被修改以减少与虚拟内容的第一部分的观看区域的任何重叠。 虚拟内容的第一部分和第二部分根据确定的观看区域在增强现实设备上呈现。

摘要： A system and head-mounted device modify display of augmented reality content during an interaction between a person and a user of a mixed reality system. The method comprises detecting an interaction between a person and a user of a mixed reality system, the mixed reality system displaying the augmented reality content to the user, the interaction being detectable by the mixed reality system when a gaze interaction of the person is detected as directed towards the user and accordingly a sensor of the mixed reality system; determining an urgency of the interaction according to further interaction between the person and the user; determining that an element of the display of the augmented reality content is obscuring the interaction; selecting a transition effect for modifying display of the element from a plurality of transition effects according to the determined urgency of the interaction, and modifying the display of the element according to the selected transition effect.

摘要： A computer-implementable system and method of displaying a document as mixed reality content. The method comprises determining, via an image of a physical environment, a relationship between an orientation of a physical document, a presenter of the physical document, and a viewer of the physical document in the physical environment; and retrieving a virtual representation of the physical document when the determined relationship indicates that the physical document is presented to the viewer. The method further comprises displaying the retrieved virtual representation of the document to the viewer as mixed reality content in the physical environment.

摘要： A system and method of controlling a virtual camera. The method comprises receiving a camera path of the virtual camera, the camera path defining movement of the virtual camera over a period of time to capture video data of a scene; and determining a plurality of control points on the camera path using a plurality of time markers within the period of time, each of the time markers corresponding to at least one event of a predetermined type being identified in the scene, wherein the control points at least partially define the camera path. The method further comprises controlling the virtual camera using the camera path modified based on the plurality of control points in response to a user input in relation to at least one of the control points.

摘要： A method of controlling a virtual camera within a three-dimensional volume associated with a scene. A virtual camera position within the three-dimensional volume is determined. Coverage, by a plurality of physical cameras, of at least a portion of the scene as viewed from a plurality of viewpoints associated with the virtual camera position, is determined. The virtual camera is controlled to generate a view of the scene, based on the determined coverage, in response to receiving a user command changing at least one viewpoint attribute of the virtual camera.
