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: Systems and methods for a markerless approach to displaying an image of a virtual object in an environment are described. A computing device is used to capture an image of a real-world environment; for example including a feature-rich planar surface. One or more virtual objects which do not exist in the real-world environment are displayed in the image, such as by being positioned in a manner that they appear to be resting on the planar surface, based at least on a sensor bias value and scale information obtained by capturing multiple image views of the real-world environment.

Abstract: Various embodiments enable a computing device to perform tasks such as highlighting words in an augmented reality view that are important to a user. For example, word lists can be generated and the user, by pointing a camera of a computing device at a volume of text, can cause words from the word list within the volume of text to be highlighted in a live field of view of the camera displayed thereon. Accordingly, users can quickly identify textual information that is meaningful to them in an Augmented Reality view to aid the user in sifting through real-world text.

Abstract: Systems and methods for displaying 3D containers in a computer generated environment are described. A computing device may provide a user with a catalog of objects which may be purchased. In order to view what an object may look like prior to purchasing the object, a computing device may show a 3D container that has the same dimensions as the object. As discussed herein, the 3D container may be located and oriented based on a two-dimensional marker. Moreover, some 3D containers may contain a representation of an object, which may be a 2D image of the object.

Abstract: Various algorithms are presented that enable an image of a data matrix to be analyzed and decoded for use in obtaining information about an object or item associated with the data matrix. The algorithms can account for variations in position and/or alignment of the data matrix. In one approach, the image is analyzed to determine a connected region of pixels. The connected region of pixels can be analyzed to determine a pair of pixels, included in the connected region of pixels, that is separated a greatest distance wherein a first pixel and second pixel of the pair of pixels is associated with image coordinates. Using the image coordinates of the pair of pixels, a potential area of the image that includes the visual code can be determined and the potential area can be analyzed to verify the presence of a potential data matrix.

Abstract: Various approaches provide for detecting and recognizing text to enable a user to perform various functions or tasks. For example, a user could point a camera at an object with text, in order to capture an image of that object. The camera can be integrated with a portable computing device that is capable of taking the image and processing the image (or providing the image for processing) to recognize, identify, and/or isolate the text in order to send the image of the object as well as recognized text to an application, function, or system, such as an electronic marketplace.

Abstract: Various embodiments enable text aggregation from multiple image frames of text. Accordingly, in order to stitch newly scanned areas of a document together, text in a respective image is recognized and analyzed using an algorithm to identify pairs of corresponding words in other images. Upon identifying a minimum number of matching pairs between two respective images, a mapping between the same can be determined based at least in part on a geometric correspondence between respective identified pairs. Based on this mapping, the recognized text of the two images can be merged by adding words of one image to the other using the matching word pairs as alignment data points.

Abstract: Approaches are described for rendering augmented reality overlays on an interface displaying the active field of view of a camera. The interface can display to a user an image or video, for example, and the overlay can be rendered over, near, or otherwise positioned with respect to any text or other such elements represented in the image. The overlay can have associated therewith at least one function or information, and when an input associated with the overlay is selected, the function can be performed (or caused to be performed) by the portable computing device.

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.
