    • A “Contact Discriminator” provides various techniques for differentiating between valid and invalid contacts received from any input methodology by one or more touch-sensitive surfaces of a touch-sensitive computing device. Examples of contacts include single, sequential, concurrent, or simultaneous user finger touches (including gesture type touches), pen or stylus touches or inputs, hover-type inputs, or any combination thereof. The Contact Discriminator then acts on valid contacts (i.e., contacts intended as inputs) while rejecting or ignoring invalid contacts or inputs. Advantageously, the Contact Discriminator is further capable of disabling or ignoring regions of input surfaces, such tablet touch screens, that are expected to receive unintentional contacts, or intentional contacts not intended as inputs, for device or application control purposes. Examples of contacts not intended as inputs include, but are not limited to, a user's palm resting on a touch screen while the user writes on that screen with a stylus or pen.
    • “接触鉴别器”提供了各种用于区分由触敏计算设备的一个或多个触敏表面从任何输入方法接收的有效和无效联系的各种技术。 触点的示例包括单个,顺序,并发或同时用户手指触摸(包括手势类型触摸),笔或触控笔触摸或输入,悬停式输入或其任何组合。 然后,接触鉴别器对拒绝或忽略无效联系人或输入的有效联系人(即,作为输入的联系人)起作用。 有利地,接触鉴别器还能够禁用或忽略预期将接收无意接触的输入表面(例如平板电脑触摸屏)的区域或用于设备或应用控制目的的意图不是输入的有意联系人。 不用于作为输入的触点的示例包括但不限于用户的手掌搁在触摸屏上,同时用户用触针或笔在该屏幕上写入。

    • Various embodiments are disclosed that relate to the presentation of video images in a presentation space via a head-mounted display. For example, one disclosed embodiment comprises receiving viewer location data and orientation data from a location and orientation sensing system, and from the viewer location data and the viewer orientation data, locate a viewer in a presentation space, determine a direction in which the user is facing, and determine an orientation of the head-mounted display system. From the determined location, direction, and orientation, a presentation image is determined based upon a portion of and an orientation of a volumetric image mapped to the portion of the presentation space that is within the viewer's field of view. The presentation image is then sent to the head-mounted display.
    • 公开了涉及通过头戴式显示器在呈现空间中呈现视频图像的各种实施例。 例如,一个公开的实施例包括从位置和方向感测系统接收观看者位置数据和取向数据,并且从观众位置数据和观看者方向数据中,将观看者定位在呈现空间中,确定用户的方向 面对并确定头戴式显示系统的方向。 根据确定的位置,方向和方向,基于映射到在观看者的视野内的呈现空间的部分的体积图像的一部分和取向来确定呈现图像。 然后将演示图像发送到头戴式显示器。

    • A method for constructing a 3D representation of a subject comprises capturing, with a camera, a 2D image of the subject. The method further comprises scanning a modulated illumination beam over the subject to illuminate, one at a time, a plurality of target regions of the subject, and measuring a modulation aspect of light from the illumination beam reflected from each of the target regions. A moving-mirror beam scanner is used to scan the illumination beam, and a photodetector is used to measure the modulation aspect. The method further comprises computing a depth aspect based on the modulation aspect measured for each of the target regions, and associating the depth aspect with a corresponding pixel of the 2D image.
    • 用于构建对象的3D表示的方法包括用相机拍摄对象的2D图像。 该方法还包括扫描对象上的调制照明光束以一次一个地照射被摄体的多个目标区域,以及测量来自每个目标区域反射的照明光束的光的调制方面。 使用移动镜光束扫描器来扫描照明光束,并且光电检测器用于测量调制方面。 该方法还包括基于针对每个目标区域测量的调制方面来计算深度方面,以及将深度方面与2D图像的对应像素相关联。
