A method is provided to place new slides on zooming user interface canvas is provided that includes: receiving user request to add a new slide; determining whether a zoom level of a current viewing window has changed to meet a prescribed threshold zoom level since addition of a previously added slide; in response to a determination that the zoom level has changed, using a current viewing window zoom level as a reference zoom level; in response to a determination that the zoom level has not changed, using a previous viewing window zoom level as the reference zoom level; and determining a placement of the new slide with reference to the reference zoom level.

Adding new slides on a canvas in a zooming user interface

A method is provided to edit a display screen of a zooming user interface system; the method includes receiving a user request to transform a set of display elements that are displayed on a display screen encompassed by a frame; in response to the user request an information structured is produced in a non-transitory storage device that indicates each display element of the set of display elements that is displayed on the display screen encompassed by the frame; each display element indicated by the information structure is transformed according to the user request.

Grouping with frames to transform display elements within a zooming user interface

A method is provided method to control a computer generated presentation using a two-dimensional (2D) zooming user interface, the method comprising: providing on the display screen multiple respective thumbnail images that correspond to the multiple screen images displayed within the presentation; and in response to receipt of user input selecting one thumbnail image followed by receipt of user input selecting another of the thumbnail image, displaying on the display screen a screen image that corresponds to the user selected one thumbnail image followed by display on the display screen of another thumbnail image that corresponds to the user selected another thumbnail image and display of at least one of panning and zooming between display of the one thumbnail image and the another thumbnail image.

Navigation with slides in a zooming user interface

A method is provided to display an image frame sequence comprising: displaying an image frame sequence on a display screen; and in the course of displaying the image frame sequence, displaying a zooming user interface (ZUI) frame sequence on the display screen.

Zooming user interface frames embedded image frame sequence

An apparatus and method for 3D rendering of a canvas and at least a first background in a ZUI environment are disclosed herein. Within a viewing window, display at least a portion of the canvas and at least a portion of the first background in parallax. Receive a user action taken on the viewing window that triggers a change in the displaying of the canvas and the first background. Calculate a first transform value and a first transparency value for the first background, in response to the received user action. Update the display of the canvas and the first background in response to the received user action, the canvas updated in accordance with the received user action and the first background updated in accordance with the first transform value and the first transparency value.
