  • Patent number: 10223330
    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.
    Type: Grant
    Filed: August 26, 2015
    Date of Patent: March 5, 2019
    Assignees: CITY UNIVERSITY OF HONG KONG, THE HONG KONG UNIVERSITY OF SCIENCE AND TECHNOLOGY

  • Patent number: 9542068
    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.

  • Patent number: 9104308
    Abstract: Described herein are finger registration systems and methods for use with a multi-touch device that can facilitate in place execution of commands or operations, thereby reducing focus switching and minimizing hand movement. The finger registration methods are simple and robust, using only contact points on the touch-based device, without requiring additional hardware. Direct mapping of operations to gestures involving individual fingers or combination of fingers (e.g., finger chords), provides a new and rich set of direct manipulation without focus switching for selecting commands/operations.
