    Abstract: A virtual vertical surface in a three-dimensional space that represents a physical room may be detected. Responsive to a first user input gesture, movement of a virtual object within the three-dimensional space may be displayed. The movement may be to a first location in which a portion of the virtual object intersects a portion of the virtual vertical surface. A virtual vertical surface designator may be displayed corresponding to the virtual vertical surface based at least in part on the portion of the virtual object intersecting the portion of the virtual vertical surface. Upon determining that a second user input gesture meets or exceeds a movement threshold, movement of the three-dimensional object from the first location to a second location within the three-dimensional space may be displayed. The second location may appear beyond the virtual vertical surface.

    Abstract: Approaches in accordance with various embodiments provide for the presentation of augmented reality (AR) content with respect to optically challenging surfaces. Such surfaces can be difficult to locate using conventional optical-based approaches that rely on visible features. Embodiments can utilize the fact that horizontal surfaces can be located relatively easily, and can determine intersections or boundaries of those horizontal surfaces that likely indicate the presence of another surface, such as a vertical wall. This boundary can be determined automatically, through user input, or using a combination of such approaches. Once such an intersection is located, a virtual plane can be determined whose relative location to a device displaying AR content can be tracked and used as a reference for displaying AR content.

    Abstract: Devices, systems, and methods are provided for real-time object placement guidance in augmented reality experience. An example method may include receiving, by a device having a sensor, an indication of an object to be viewed in an physical environment of the device. The example method may also include determining a 3D model of the physical environment using data of the physical environment captured by the sensor. The example method may also include determining that a first surface in the 3D model of the environment is a first floor space, and a second surface in the 3D model of the environment is a first wall space. The example method may also include determining that a portion of the first surface is unoccupied and sized to fit the object. The example method may also include determining a first location in the 3D model of the physical environment for placement of a virtual representation of the object based on a 3D model of the object, wherein the first location corresponds to the portion of the first floor space. The example method may also include generating the virtual representation of the object for display at the first location, the virtual representation of the object having a first orientation, wherein the first orientation is based on a second orientation of the second surface. The example method may also include generating a first real-time view of the physical environment comprising the virtual representation of the object within the portion of the first location and in the first orientation. In some cases, a real-time virtual overlay may also be generated in the physical environment, the real-time virtual overlay indicating a location of a floor space in the physical environment.

    Abstract: A complex three-dimensional virtual representation of an object can be rendered. Virtual images can be captured representing a plurality of views of the complex virtual representation. The virtual images can be converted into binary masks depicting the object pixels and non-object pixels in the virtual images. The binary masks can be used to create a three-dimensional representation of the object having lower complexity than the first three-dimensional virtual representation of the object. In embodiments, the low complexity three-dimensional virtual representation of the object and the virtual images are sent to a mobile device to render a low payload representation of the object on the mobile device.
