Abstract

The contents displayed on the touch screen of a mobile device are modified based in user input, in the form of touch input. In one mode, a content view, contents of a document are displayed to a user at various zoom levels. The user can zoom-out by indicating in one embodiment a pinching touch motion. The user can also switch to another viewing mode, a structure view, where structure of the document is displayed to the user, potentially at various zoom levels. The user can zoom-out in the structure view also by providing a pinching touch motion. The user can switch to the content view by selecting text in the structure view, which then presents the contents of the document at the corresponding location.

Claims

1. A method for an application program to modify information displayed on a device, comprising:

displaying on the device by the application program at least a first portion of a document at a first content zoom level;

receiving on the device a first input from a user;

responsive to receiving the first input, retrieving from a memory in the device document-related structure data associated with the document, the document-related structure data being derived from text within the document corresponding to at least one of a heading, a title or a table of contents;

displaying on the device by the application program an outline having a primary level of information based on at least a first portion of the document-related structure data corresponding to the first content zoom level, the outline replacing the display of at least the first portion of the document;

receiving on the device a second input from the user comprising a request to display a secondary level of information based on at least a second portion of the document-related structure data; and

displaying on the device the secondary level of information within the displayed outline based on the request to display the secondary level of information.

2. The method of claim 1, further comprising:

prior to receiving the input from the user requesting to change from a content view to a structure view, receiving a third input from the user comprising a request to zoom-out from the document; and

displaying at least a second portion of the document, wherein the second portion displayed is a superset of the first portion of the document.

3. The method of claim 2, wherein the device further comprises a touch screen, and

wherein the third input from the user comprises a finger-pinching movement of two fingers on the touch screen.

4. The method of claim 1, wherein the device further comprises a touch screen, and

wherein the first input comprises tapping the touch screen with two fingers simultaneously.

5. The method of claim 4, further comprising:

receiving a third input from the user after displaying at least the first portion of the document-related structure data, wherein the third input selects a text portion within the document-related structure data, wherein said text portion corresponds to a heading within the document; and

displaying on the device by the application program in place of the document-related structure data at least a portion of the document comprising the heading.

6. The method of claim 5, wherein the device further comprises a touch screen, and

wherein the third input comprises a single tap on the touch screen of a finger of the user.

7. The method of claim 1, wherein the document comprises a series of slides and the application program comprises a slide presentation application program.

8. A system to modify information displayed on a device comprising:

a memory configured to store a document and document-related structure data associated with the document, the document-related structure data being derived from text within the document and based on at least one of a heading, a title or a table of contents;

a display; and

a central processing unit configured to receive user input and execute an application program configured to manipulate the document and present at least a portion of the document on the display and to further configure the central processing unit to

display a first portion of the document at a first content zoom level on the display,

receive a first input from the user,

responsive to receiving the first input, retrieve first document-related structure data from the memory, the,

display on the device an outline having a primary level of information based on at least a portion of the first document-related structure data corresponding to the first content zoom level, the outline replacing the display of at least the first portion of the document,

receive a second input from the user,

retrieve second document-related structure data from the memory, and

responsive to receiving the second input, display on the device a secondary level of information within the displayed outline based on at least a portion of the second document-related structure data,

wherein the first and second document-related structure data being derived from text within the document corresponding to at least one of a heading, a title or a table of contents.

9. The system of claim 8, wherein the device further comprises a touch screen, and

wherein the touch screen is configured to detect two fingers simultaneously touching the touch screen.

10. The system of claim 8, wherein the central processing unit is configured to display the first portion of the document on the display in a content viewing mode and display the document-related structure data in a structure viewing mode.

11. The system of claim 10, wherein the device further comprises a touch screen, and

wherein the central processing unit is configured to

switch to the content viewing mode from the structure viewing mode in response to user input selecting a portion of the document-related structure data, and

switch to the structure viewing mode from the content viewing mode when detecting two fingers simultaneously touching the touch screen.

12. The system of claim 8, wherein the device further comprises a touch screen, and an accelerometer detecting the user touching the touch screen.

13. One of an optical disk, a magnetic storage device or a solid state memory having computer-executable instructions stored thereon that, when executed by a central processing unit, cause the central processing unit to:

present at least a portion of a document at a first content zoom level on a display of a device;

receive a first input from a user, the first input comprising a pinching movement input to the device requesting to change from a content view to a structure view;

responsive to receiving the first input, retrieve document-related structure data from a memory of the user device, the document-related structure data being derived from text within the document corresponding to at least one of a heading, a title or a table of contents;

display on the display of the device an outline having a primary level of information based on at least a first portion of the document-related structure data corresponding to the first content zoom level, the outline replacing the presentation of at least the portion of the document;

receive a second input from the user requesting to display a secondary level of information based on at least a second portion of the document-related structure data; and

display on the display of the device the secondary level of information within the displayed outline in response to receiving the request of the second input from the user.

14. The optical disk, magnetic storage device or solid state memory of claim 13, further comprising instructions causing the central processing unit to:

prior to receiving the input from the user requesting to change from a content view to a structure view, receive a third input from the user requesting to zoom-out from the document; and

display in response to the third input a second portion of the document, wherein the second portion is a superset of the portion of the document.

15. The optical disk, magnetic storage device or solid state memory of claim 14, wherein the device further comprises a touch screen, and

further comprising instructions causing the computer to ascertain that the third input from the user requesting to zoom-out from the document comprises a pinching motion of two fingers touching the touch screen.

16. The optical disk, magnetic storage device or solid state memory of claim 13, wherein the device further comprises a touch screen, and

further comprising instructions causing the computer to interpret touching of two fingers simultaneously on the touch screen as the first input from the user requesting to change from the content view to the structure view.
