Method and apparatus for a GUI look -ahead window.

Using a electronic display to view content like a music sheet/presentation slide while being able to 'look-ahead' is a desired feature for musicians, presenters, etc. It is difficult to look-ahead of the current content (to the upcoming content) with existing solutions.

The following features would be desired for any solution to the above problem:
1) Content switches automatically, but can be overridden.
2) Upcoming content can be displayed in close proximity to the current content.
3) All content can be displayed at the maximum rate (i.e., font).

    The proposed invention is made possible in part by the use of predefined inputs. It provides for the above features in addition to other visual and usability benefits.


The proposed idea is designed to maximize the display size and provide for the natural movement of content while allowing the viewer to look-ahead.

    With respect to book pages, music sheets, presentation slides and other medium that is viewable on a electronic display device, a look-ahead GUI window is interesting. This proposed 'look-ahead' window, that holds the upcoming content, is displayed relative to an invisible/visible 'marker' called the machine's focus (focus X) as determined by various inputs. Those inputs include predefined pace, timing, sensing external media (speech or audio) and synching with the contents, and remote control(s). The actual location of focus X within the 'parent' window, that holds the current content, is determined by the above prescribed inputs. The look-ahead window is also contained within the parent window (but not limited to).

    The viewer's focus (focus Y) will only map occasionally to the previously defined focus X. For example, focus Y could be ahead/behind the focus X, in the look-ahead window or elsewhere.

    Segmented content is defined as medium that represents a complete thought such as a page in a book, a graphic, a presentation slide, or a music sheet. Although they could be scrolled by reorganizing the content into a stream, not all of this media can be reorganized (the slide, sheet or graphic). This invention attempts to solves this limitation and also provides for visual and usability benefits.

Electronic music sheet scenario

1) On the display a single sheet is displayed (e.g., sheet 3 of 7).
2) Device receives input on where the focus X is by either MIDI, music recognition (i.e., like voice recognition), etc. For example, the song starts and the device receives input on which note to display in a blinking state. This blinking note is focus X which is the actual note to be played next.
3) As the musician reads the music sheet, focus X moves. Once focus X is far enough along, a proportioned look-ahead window is displayed in the top right corner of the parent window. This window grows gradually as the musician reads the sheet (i.e., focus X moves) until at the last moment the look-ahead window is on top of the parent window.
