Abstract: Techniques for simulating interactions using an augmented reality device are described. Embodiments receive a request to paint over portions of a visual scene. Here, the visual scene is captured using one or more camera devices of the augmented reality device and is presented on a display of the augmented reality device. A first object in the visual scene corresponding to the first location is identified. Additionally, embodiments paint at least a portion of the first object as specified by the received request, and render a series of frames depicting the first object, such that the painted at least a portion of the first object is shown as painted when viewed from different perspectives using the augmented reality device.

Abstract: Techniques are disclosed for rendering an anamorphic projection of 3D scene geometry on a handled device using a correct asymmetric perspective geometry projection. Once pose of the handheld device is determined, a relative eye position may be inferred when the device is tilted away from an initial or default pose, based on data supplied by accelerometers. Thus, embodiments of the invention result in a holographic style display without the need for glasses or external sensing attachments.

Abstract: There is provided a system and method for augmented reality image transformation. In one implementation, such a system includes a system processor, a system memory, and an image transformation engine stored in the system memory. The system processor is configured to execute the image transformation engine to receive image data corresponding to an image, to detect a feature on a surface of the image, and to synthesize a texture corresponding to the feature. The system processor is further configured to execute the image transformation engine to produce an augmented reality representation of the image having the texture for display to a user, the texture covering a surface of the augmented reality representation of the image corresponding to a portion of the feature that is not visible on the surface of the image.

Abstract: The disclosure provides an approach for determining, in 3D rendering, the integrals of visibility-masked spherical functions using visibility silhouettes. For a given shade point, the visibility silhouette for that shade point includes a set of edges from the scene geometry which form the boundaries between visible and invisible regions of a hemisphere having the shade point as its center. For each shade point, a rendering application determines a set of contour edges of scene geometry, the contour edges being a superset of the set of visibility silhouette edges, by querying a 4D dual mesh. The rendering application then evaluates the integral of the visibility-masked spherical function for a given shade point by integrating over segments of discrete u-isolines for which an overlap function indicates that a ray from the shade point would not intersect scene geometry.

Abstract: A method is provided for an optimized stereoscopic camera with low processing overhead, especially suitable for real-time applications. By constructing a viewer-centric and scene-centric model, the mapping of scene depth to perceived depth may be defined as an optimization problem, for which a solution is analytically derived based on constraints to stereoscopic camera parameters including interaxial separation and convergence distance. The camera parameters may thus be constrained prior to rendering to maintain a desired perceived depth volume around a stereoscopic display, for example to ensure user comfort or provide artistic effects. To compensate for sudden scene depth changes due to unpredictable camera or object movements, as may occur with real-time applications such as video games, the constraints may also be temporally interpolated to maintain a linearly corrected and approximately constant perceived depth range over time.

Abstract: An augmented reality (AR) audio system for augmenting environment or ambient sound with sounds from a virtual speaker or sound source positioned at a location in the space surrounding an AR participant. The sound from the virtual speaker may be triggered by an action of the listener and/or by the location or relative orientation of the listener. The AR audio system includes stereo earphones receiving an augmented audio track from a control unit, and binaural microphones are provided to capture ambient sounds. The control unit operates to process trigger signals and retrieve one or more augmentation sounds. The control unit uses an AR audio mixer to combine the ambient sound from the microphones with the augmentation sounds to generate left and right ear augmented audio or binaural audio, which may be modified for acoustic effects of the environment including virtual objects in the environment or virtual characteristics of real objects.

Abstract: Techniques are disclosed for performing image space reprojection iteratively. An insignificant parallax threshold depth is computed for a source image. Portions of the image having depth values greater than the insignificant parallax threshold depth may be shifted uniformly to produce corresponding portions of the reprojection (target) image. An iterative fixed-point reprojection algorithm is used to reproject the portions of the source image having depth values less than or equal to the insignificant parallax threshold depth. The fixed point reprojection algorithm quickly converges on the best pixel in the source image for each pixel in a target image representing an offset view of the source image. An additional rendering pass is employed to fill disoccluded regions of the target image, where the reprojection algorithm fails to converge.
