摘要： A passive projection screen presents images projected thereon by a projection system. A surface of the screen includes elements that are reflective to non-visible light, such as infrared (IR) light. When non-visible light is directed to the screen, the non-visible light is reflected by the reflective elements back. Part of the reflected light may contact and reflect from a user's fingertip or hand (or other object, such as a stylus) while another part is reflected to the projection system. The projection system differentiates among distances to the surface and distances that include the additional travel to the fingertip. As the fingertip moves closer to the surface, the distances approach equality. When the distances are approximately equal, the finger is detected as touching the surface. In this manner, a projection surface equipped with reflective elements facilitates more accurate touch detection.
摘要翻译：被动投影屏幕呈现通过投影系统投影在其上的图像。屏幕的表面包括反射不可见光的元件，例如红外（IR）光。当不可见光被引导到屏幕时，不可见光被反射元件反射回来。反射光的一部分可以从用户的指尖或手（或其他物体，例如触针）接触并反射，而另一部分被反射到投影系统。投影系统区分到表面的距离和距离，包括对指尖的额外行进。当指尖靠近表面移动时，距离接近平等。当距离近似相等时，手指被检测为接触表面。以这种方式，配备有反射元件的投影表面有助于更准确的触摸检测。

摘要： A user device may include one or more features on a surface of the user device, where a user may interact with the one or more features. In response to a user action with respect to one of the features, a particular sound, frequency, or change in frequency may be output. An augmented reality functional node (ARFN) may detect the sound or frequency and identify a particular operation that corresponds to the sound or frequency. The ARFN may then cause that operation to be performed within an environment.
摘要翻译：用户设备可以包括在用户设备的表面上的一个或多个特征，其中用户可以与一个或多个特征交互。响应于用户对于特征之一的动作，可以输出特定的声音，频率或频率变化。增强现实功能节点（ARFN）可以检测声音或频率，并识别对应于声音或频率的特定操作。然后ARFN可以使该操作在环境中执行。

摘要： Calibration of devices may be performed to determine a relative location of the devices. The devices may be used to determine distances of surfaces within an environment. The calibration may be performed at different times and/or in response to triggering events to determine a relative location of each of the devices in an environment. After the relative location of the devices is known, the devices may be used to determine a distance of a surface within the environment. In various embodiments, a light sensor may identify a light emitter based on characteristics of the light emitted by the light emitter.

摘要： A projector based user interface unit is described for implanting an interactive workspace. The interface unit projects a graphical workspace onto a display surface and monitors user interactions with the workspace. A mirror is placed on or near the workspace to reflect the face of the user to the interface unit. The interface unit captures the mirrored face of the user and provides images of the face of the user to other users for use in conjunction with collaborative techniques such as video conferencing or content sharing.

摘要： In some embodiments, distances associated with a surface may be calculated using time-of-flight (ToF) of a plurality of pulses of light occurring at a predetermined frequency. Reflected light from a light emitter may be captured by two or more light sensors. At least one light sensor may be located in a sensor pod that is separate from the light emitter, which may be housed in an emitter pod with or without a light sensor. The sensor pod may be synchronized with the emitter pod to enable ToF of light distance calculations. The calculated distance may be used to determine movement of a surface and/or one or more pixels of a surface. In some instances, the calculated distance may be used to identify a profile of a surface, which may then be used associate the profile with an object, a command, or another association.

摘要： A voice controlled assistant has a housing to hold one or more microphones, one or more speakers, and various computing components. The housing has an elongated cylindrical body extending along a center axis between a base end and a top end. The microphone(s) are mounted in the top end and the speaker(s) are mounted proximal to the base end. A control knob is rotatably mounted to the top end of the housing to rotate about the center axis. A light indicator is arranged on the control knob to exhibit various appearance states to provide visual feedback with respect to the one or more functions being performed by the assistant. In one case, the light indicator is used to uniquely identify participants involved in a call.
