    摘要: An augmented reality environment allows interaction between virtual and real objects. Various surfaces within the environment such as walls, tables, countertop, chairs, floor, ceiling, and so forth may be used as projection surfaces. Qualified projection surfaces are determined, and an initial projection surface is selected for use from these. This selection may take into account user preferences, user orientation, types of image to be projected, and so forth. Other qualified projection surfaces may have visual indicators projected thereon, indicating relative suitability for use as a projection surface.

    摘要: Systems and techniques for providing feedback to users within an environment that interact with user interfaces (UIs) that are projected within the environment. For instance, the systems and techniques may project a UI that includes one or more selectable portions, such as keys, icons, sliders, dials, or any other type of control. After projecting the UI, the systems and techniques may identify the user attempting to interact with the UI. In response, the systems and techniques may provide feedback to the user indicating that the user has engaged the UI. For instance, the systems and techniques may visually alter the projected UI, may output a sound via one or more speakers within the environment, or may provide the feedback in any other manner.

    摘要: Devices and techniques are described for automatically calibrating a device such as a camera, projector, or both using a video stream. The device undergoing calibration is coupled to a computing device and configured to acquire video comprising a plurality of images. These images, at least some of the time, include targets having known characteristics present in an environment. From these acquired images calibration data comprising parameters such as intrinsic parameters, extrinsic parameters, or both, may be determined. The calibration data may be embedded or otherwise associated with the video stream as calibration matrix metadata.
