    Abstract: An optical flow of depth video of a depth camera imaging a human subject is recognized. An energy field created by motion of the human subject is generated as a function of the optical flow and specified rules of a physical simulation of the virtual environment. The energy field is mapped to a virtual position in the virtual environment. A property of a virtual object in the virtual environment is adjusted based on a plurality of energy elements of the energy field in response to the virtual object interacting with the virtual position of the energy field.

    Abstract: An intuitive interface may allow users of a computing device (e.g., children, etc.) to create imaginary three dimensional (3D) objects of any shape using body gestures performed by the users as a primary or only input. A user may make motions while in front of an imaging device that senses movement of the user. The interface may allow first-person and/or third person interaction during creation of objects, which may map a body of a user to a body of an object presented by a display. In an example process, the user may start by scanning an arbitrary body gesture into an initial shape of an object. Next, the user may perform various gestures using his body, which may result in various edits to the object. After the object is completed, the object may be animated, possibly based on movements of the user.

    Abstract translation: 直观界面可允许计算设备（例如，儿童等）的用户使用由用户执行的身体手势作为主要或仅输入来创建任何形状的假想三维（3D）对象。 用户可以在感测用户的移动的成像装置的前面进行运动。 接口可以允许在创建对象期间的第一人和/或第三人交互，这可以将用户的身体映射到由显示器呈现的对象的主体。 在示例过程中，用户可以通过将任意身体手势扫描成对象的初始形状来开始。 接下来，用户可以使用他的身体执行各种手势，这可能导致对对象的各种编辑。 在对象完成之后，可以基于用户的移动来对对象进行动画化。

    Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution of lighting estimation. In the solution, an input image about a real object and a depth map corresponding to the input image are obtained. A geometric structure of the scene in the input image is determined based on the depth map. Shading and shadow information on the real object caused by a light source in the scene is determined based on the determined geometric structure of the scene. Then, a lighting condition in the scene caused by the light source is determined based on the input image and the shading and shadow information. The virtual object rendered using the lighting condition obtained according to the solution can exhibit a realistic effect consistent with the real object.
