Abstract

A development tool simplifies layout of a part for a multimedia title. A spacer tool may be placed onto a graphical representation of a part. The spacer tool may be a play spacer which plays the part for a designated period of time, a hide spacer which hides what would have been an otherwise visible portion of a part, a rate spacer which changes the rate at which the part is played, or a move spacer which causes a part to move along a predetermined path while visible.

Claims

1. A user interface tool on a computer system for simplifying layout of a part of a multimedia title, comprising:

a user interface which allows an at a glance relational visual layout of a plurality of parts in terms of a time structure thereof;

a graphically depicted part action sequence for each of said plurality of parts over a period of time;

a plurality of spacer tools graphically represented on said user interface, wherein each of said spacer tools represents an action that may be applied to modify the part action sequence of one or more of said parts;

means, operable by a user of said tool, for dragging said graphical representation of a selected one of said spacer tools;

means, operable by said user, for dropping said graphical representation of said selected spacer tool onto said graphically depicted part action sequence of a selected one of said parts;

means, responsive to said dragging and dropping, for;

displaying a spacer icon and a spacer area corresponding to said selected spacer tool at a location where said selected spacer tool was dropped, and

modifying said part action sequence of said selected part to perform said represented action during a first time frame corresponding to said location;

means, selectable by said user, for adjusting said first time frame by dragging a size handle graphically depicted on said spacer area to change a width of said spacer area; and

means, responsive to said adjusting, for further modifying said part action sequence of said selected part to perform said represented action for said adjusted time frame corresponding to said changed width of said spacer area.

2. The tool of claim 1, wherein said selected one of said spacer tools is a play spacer, and wherein said represented action comprises:

playing the selected part for said adjusted time frame if said means for adjusting have been selectably used, or for said first time frame otherwise.

3. The tool of claim 1, wherein said selected one of said spacer tools is a hide spacer, and wherein said represented action comprises:

hiding the selected part for said adjusted time frame if said means for adjusting have been selectably used, or for said first time frame otherwise.

4. The tool of claim 1, wherein said selected one of said spacer tools is a rate spacer, and wherein said represented action comprises:

changing a rate at which the selected part is played over said adjusted time frame if said means for adjusting have been selectably used, or over said first time frame otherwise.

5. The tool of claim 1, wherein said selected one of said spacer tools is a move spacer, and wherein said represented action comprises:

causing said selected part to move along a predetermined path for said adjusted time frame if said means for adjusting have been selectably used, or for said first time frame otherwise.

6. A method for simplifying layout of a part for a multimedia title on a computer system, comprising the steps of:

providing a user interface which allows an at a glance relational visual layout of a plurality of parts in terms of a time structure thereof;

graphically depicting a part action sequence for each of said plurality of parts over a period of time;

graphically representing a plurality of spacer tools on said user interface, wherein each of said spacer tools represents an action that may be applied to modify the part action sequence of one or more of said parts;

selecting one of said spacer tools from a palette on the computer system;

dragging said selected spacer tool;

dropping said selected spacer tool onto said graphically depicted part action sequence of a selected one of said parts;

displaying, responsive to said dragging and dropping;

a spacer icon and a spacer area corresponding to said selected spacer tool at a location where said selected spacer tool was dropped, and

modifying said part action sequence of said selected part to perform said represented action during a first time frame corresponding to said location;

selectably adjusting said first time frame by dragging a size handle graphically depicted on said spacer area to change a width of said spacer area; and

further modifying, responsive to said adjusting, said part action sequence of said selected part to perform said represented action for said adjusted time frame corresponding to said changed width of said spacer area.

7. The method of claim 6, wherein said selected one of said spacer tools is a play spacer, and wherein:

said step of modifying said part action sequence comprises modifying said part action sequence to play the selected part for said first time frame; and

said step of further modifying said part action sequence comprises modifying said part action sequence to play the selected part for said adjusted time frame.

8. The method of claim 6, wherein said selected one of said spacer tools is a hide spacer, and wherein:

said step of modifying said part action sequence comprises modifying said part action sequence to hide the selected part for said first time frame; and

said step of further modifying said part action sequence comprises modifying said part action sequence to hide the selected part for said adjusted time frame.

9. The method of claim 6, wherein said selected one of said spacer tools is a rate spacer, and wherein:

said step of modifying said part action sequence comprises modifying said part action sequence to change a rate at which the selected part is played for said first time frame; and

said step of further modifying said part action sequence comprises modifying said part action sequence to change said rate at which the selected part is played for said adjusted time frame.

10. The method of claim 6, wherein said selected one of said spacer tools is a move spacer, and wherein:

said step of modifying said part action sequence comprises modifying said part action sequence causing said selected part to move along a predetermined path for said first time frame; and

said step of further modifying said part action sequence comprises modifying said part action sequence to move along said predetermined path for said adjusted time frame.

11. A computer program product recorded on computer readable media for simplifying layout of a part for a multimedia title on a computer system, said product comprising:

computer readable means for providing a user interface which allows an at a glance relational visual layout of a plurality of parts in terms of a time structure thereof;

computer readable means for graphically depicting a part action sequence for each of said plurality of parts over a period of time;

computer readable means for graphically representing a plurality of spacer tools on said user interface, wherein each of said spacer tools represents an action that may be applied to modify the part action sequence of one or more of said parts;

computer readable means for selecting one of said spacer tools from a palette on the computer system;

computer readable means for dragging said selected spacer tool;

computer readable means for dropping said selected spacer tool onto said graphically depicted part action sequence of a selected one of said parts;

computer readable means, responsive to said dragging and dropping, for;

displaying a spacer icon and a spacer area corresponding to said selected spacer tool at a location where said selected spacer tool was dropped, and

modifying said part action sequence of said selected part to perform said represented action during a first time frame corresponding to said location;

computer readable means for selectably adjusting said first time frame by dragging a size handle graphically depicted on said spacer area to change a width of said spacer area; and

computer readable means for further modifying, responsive to said adjusting, said part action sequence of said selected part to perform said represented action for said adjusted time frame corresponding to said changed width of said spacer area.

12. The computer program product of claim 11, wherein said selected one of said spacer tools is a play spacer, and wherein:
