Abstract: One or more devices, systems, methods and/or non-transitory, machine-readable mediums are described herein for specifying one or more events in an augmented reality (AR) environment relative to a real-world (RW) environment. A system can comprise a memory that stores executable components, and a processor, coupled to the memory, that executes or facilitates execution of the executable components. The executable components can comprise a visual component that analyzes captured visual content of a RW environment, an interface component that integrates the visual content of the RW environment with AR content of an AR environment overlaying the RW environment, and a design component that facilitates in-situ placement of the AR content in the AR environment based on the visual content being overlayed, wherein the AR content comprises a specification of an event to be executed in the RW environment that triggers a virtual asset in the AR environment.

Abstract: An enhanced multimodal interface and various enhanced tools are provided to enable a user to create 3-D augmented reality (AR) sketches using a mobile device. Mobile device can comprise a sketch generator component (SGC) that can integrate multiple sources of inputs with enhanced tools, comprising enhanced 3-D snapping and proxy creation tools. The inputs comprise touch screen data, motion data, and image data from a camera. SGC can provide the interface, which can support absolute and relative drawing. Via the interface, the user can select and use desired enhanced tools to create a 3-D AR sketch that augments visual content of a real-world environment captured by the camera with drawing content added by the user using the enhanced tools. SGC enables a user to create desired strokes, planar or curved surface proxies, snapping points, or other sketch features, wherein proxies can align with real-world surfaces.

Abstract: Group aware command based arrangement is provided. An alignment command can be received, an undirected graph comprising a group of graph nodes connected by graph edges can be constructed, wherein the group of graph nodes represent a group of selected display elements, and the undirected graph can be partitioned as a function of identifying a severable graph edge of the graph edges that connects a pair of graph nodes included in the group of graph nodes to form a first collection of graph nodes and a second collection of graph nodes.

Abstract: A stroke refinement technique can be used refine the location, orientation, and shape of input strokes by exploiting gradient features from an underlying image being traced. The technique can also be used to adjust user strokes with respect to image gradients. The stroke refinement technique can comprise a local optimization, a semi-global optimization, and a global optimization to facilitate error tolerant image optimization.

Abstract: Described herein are systems and methods that employ a widgetless and buttonless multi-touch interface for constrained manipulations of 3D objects. The widget-less multi-touch user interface can map different multi-touch gestures to different 3D object manipulation tasks, allowing a user to manipulate 3D objects without operating widgets or performing mode switchings or tool selections. User interaction is greatly simplified by using single touch actions that simultaneously specify the transformation constraint, the transformation type, and the magnitude of transformation and apply the transformation to the focus object. Additionally, the axis-based constrained manipulations support active snapping and axis transfer. Active snapping allows the user to draw a free touch path connecting two 3D objects to be snapped together, avoiding tedious operations required with standard transformation manipulations.
