Abstract

Systems and methods for undo mechanism are provided. Computer systems can have many different software elements, including application elements and file management elements. System elements can be used for user input, providing output, and manipulating data or files. In the course of using a computer system, the user may wish to return to a previous system state by undoing one or more events. In one aspect, an undo operation can be performed across multiple elements in the system (e.g., cross-application undo functionality). In another aspect, past information displayed on a display can be “recorded” so that it can later be rewound as part of a media player metaphor, and events associated with the rewound/displayed information can be undone. The media player and rewind metaphors assist users in recalling past events and/or finding actions to undo.

First claim

What is claimed is:

1. A method, comprising:
at a computing device having a display:
receiving, from a plurality of applications executed by the computing device, a sequence of events, wherein the plurality of applications includes a first application and a second application, and the sequence of events includes events that cause changes in information displayed by the display;
storing the sequence of events in a shared ordered list, wherein the shared ordered list includes:
a first application event that corresponds to an operation performed within the first application,
a system event that corresponds to opening an application, and
a second application event that corresponds to an operation performed within the second application that is different from the first application,
wherein:
the first application event, the system event, and the second application event are executed by the computing device as the events occurred in time starting with a first event and ending with a last event, and
the first application event, the system event, and the second application event are associated with visual changes in a user interface displayed on the display;

receiving an input corresponding to a selection of an undo operation; and
in response to receiving the input, undoing events in the sequence of events in two or more of the plurality of applications in the computing device, wherein:
undoing events includes beginning the undo operation with the last event in the shared ordered list wherein the last event occurred most recently in time; and
undoing events in the sequence of events in two or more of the plurality of applications in the computing device includes:
undoing the second application event in the second application in response to receiving the input;
after undoing the second application event in response to receiving the input, undoing the first application event in the first application in response to receiving the input; and
visually reversing the visual changes in the user interface displayed on the display that correspond to the first application event, the system event, and the second application event.

2. The method of claim 1 , wherein the undo operation causes a change in displayed information in two or more of the plurality of applications.

3. The method of claim 1 , wherein storing the sequence of events in the shared ordered list includes linking to the shared ordered list visual event data for a plurality of respective events in the sequence of events, wherein the visual event data includes a sequence of images showing changes in information displayed by the display during execution of the plurality of respective events, the sequence of images including at least one sequence of images for each application of the two or more applications.

4. The method of claim 3 , wherein undoing events in the sequence of events in two or more of the plurality of applications includes visually reversing the linked visual event data for the plurality of respective events in the sequence of events.

5. The method of claim 1 , wherein storing the sequence of events in the shared ordered list further includes storing one or more animations associated with a respective event of the sequence of events and further wherein undoing events in the sequence of events in two or more of the plurality of applications further includes visually reversing the one or more animations associated with the respective event.

6. The method of claim 1 , wherein the plurality of applications are two or more distinct applications selected from the group consisting of file manager applications, word processing applications, spreadsheet applications, presentation applications, internet browsers, messaging applications, email applications, video editing applications, audio editing applications, calendar applications, address book applications, media players, settings manipulation applications, search windows, notification applications, and desktop applications.

7. The method of claim 1 , wherein the plurality of applications include a file management application, and the sequence of events include one or more events in the file management application and one or more events in an application other than the file management application.

8. The method of claim 1 , wherein the shared ordered list is displayed on the display.

9. A computing device, comprising:
a display;
one or more data processors; and
one or more non-transitory computer-readable storage media including instructions that when executed by the one or more data processors cause the computing device to perform operations including:
receiving, from a plurality of applications executed by the computing device, a sequence of events, wherein the plurality of applications includes a first application and a second application, and the sequence of events includes events that cause changes in information displayed by the display;
storing the sequence of events in a shared ordered list, wherein the shared ordered list includes:
a first application event that corresponds to an operation performed within the first application,
a system event that corresponds to opening an application, and
a second application event that corresponds to an operation performed within the second application that is different from the first application,
wherein:
the first application event, the system event, and the second application event are executed by the computing device as the events occurred in time starting with a first event and ending with a last event, and
the first application event, the system event, and the second application event are associated with visual changes in a user interface displayed on the display;

receiving an input corresponding to a selection of an undo operation; and
in response to receiving the input, undoing events in the sequence of events in two or more of the plurality of applications in the computing device, wherein:
undoing events includes beginning the undo operation with the last event in the shared ordered list wherein the last event occurred most recently in time; and
undoing events in the sequence of events in two or more of the plurality of applications in the computing device includes:
undoing the second application event in the second application in response to receiving the input;
after undoing the second application event in response to receiving the input, undoing the first application event in the first application in response to receiving the input; and
visually reversing the visual changes in the user interface displayed on the display that correspond to the first application event, the system event, and the second application event.

10. The computing device of claim 9 , wherein the undo operation causes a change in displayed information in two or more of the plurality of applications.

11. The computing device of claim 9 , wherein storing the sequence of events in the shared ordered list includes linking to the shared ordered list visual event data for a plurality of respective events in the sequence of events, wherein the visual event data includes a sequence of images showing changes in information displayed by the display during execution of the plurality of respective events, the sequence of images including at least one sequence of images for each application of the two or more applications.

12. The computing device of claim 11 , wherein undoing events in the sequence of events in two or more of the plurality of applications includes visually reversing the linked visual event data for the plurality of respective events in the sequence of events.
