    Abstract: A unique system and method is provided that facilitates pixel-accurate targeting with respect to multi-touch sensitive displays when selecting or viewing content with a cursor. In particular, the system and method can track dual inputs from a primary finger and a secondary finger, for example. The primary finger can control movement of the cursor while the secondary finger can adjust a control-display ratio of the screen. As a result, cursor steering and selection of an assistance mode can be performed at about the same time or concurrently. In addition, the system and method can stabilize a cursor position at a top middle point of a user's finger in order to mitigate clicking errors when making a selection.

    Abstract: Different techniques of processing user interactions with a computing system are described. In one implementation, an interactive display is configured to depict a graphical user interface which includes a plurality of different types of user interface elements (e.g., button-type element, scroll bar-type element). A user may use one or more user input object (e.g., finger, hand, stylus) to simultaneously interact with the interactive display. A plurality of different user input processing methods are used to process user inputs received by the graphical user interface differently and in accordance with the types of the user interface elements which are displayed. The processing of the user inputs is implemented to determine whether the user inputs control the respective user interface elements. The processing may determine whether the user inputs activate and/or manipulate the displayed user interface elements in but one example.

    Abstract: The interactive and shared surface technique described herein employs hardware that can project on any surface, capture color video of that surface, and get depth information of and above the surface while preventing visual feedback (also known as video feedback, video echo, or visual echo). The technique provides N-way sharing of a surface using video compositing. It also provides for automatic calibration of hardware components, including calibration of any projector, RGB camera, depth camera and any microphones employed by the technique. The technique provides object manipulation with physical, visual, audio, and hover gestures and interaction between digital objects displayed on the surface and physical objects placed on or above the surface. It can capture and scan the surface in a manner that captures or scans exactly what the user sees, which includes both local and remote objects, drawings, annotations, hands, and so forth.

    Abstract: Aspects of the present disclosure relate to distributed virtual reality. In examples, a depth buffer and a color buffer are generated at a presenter device as part of rendering a virtual environment. The virtual environment may be perceived by a user in three dimensions (3D), for example via a virtual reality (VR) headset. Virtual environment information comprising the depth buffer and the color buffer may be transmitted to a viewer device, where it is used to render the virtual environment for display to a viewer. For example, the viewer may similarly view the virtual environment in 3D via a VR headset. A viewer perspective (e.g., from which the virtual environment is generated for the viewer) may differ from a presenter perspective and may be manipulated by the viewer, thereby decoupling the viewer's perception of the virtual environment from that of the presenter.

    Abstract: The subject application relates to a system(s) and/or methodology that facilitate vision-based projection of any image (still or moving) onto any surface. In particular, a front-projected computer vision-based interactive surface system is provided which uses a new commercially available projection technology to obtain a compact, self-contained form factor. The subject configuration addresses installation, calibration, and portability issues that are primary concerns in most vision-based table systems. The subject application also relates to determining whether an object is touching or hovering over an interactive surface based on an analysis of a shadow image.
