Abstract: A computer-implemented method and system enables the execution of multiple commands from a single gesture by detecting an object is touching a touchscreen device, timing the duration that the object remains on the surface of the touchscreen device, indicating the length of the duration, and executing one of two or more commands based on the length of the duration.

Abstract: A computer-implemented method and system for implementing a user interface (UI) tool for a touchscreen computer device displays a UI tool on a display of the touchscreen computer device. The UI tool is initially offset from a position of an object touching the surface of the display. The user controls the UI tool using the object. A command is executed, which operates on an entity indicated by the UI tool.

Abstract: A change in orientation or reorientation operation is applied to 3D models while maintaining constant zoom level of model display. The orientation is provided by a computer-based tool or GUI widget formed of a transparent container element and a miniaturized depiction of the 3D model. The transparent container element encapsulates the miniaturized depiction and enables see through view of the miniaturized depiction illustrating real time orientation of the 3D model. The container element is user-interactive to effect change in orientation of the 3D model concurrently displayed in a work area of a screen view. The zoom level of the displayed 3D model in the work area remains constant avoiding or omitting zoom to extents throughout user interaction with the GUI widget.
