Abstract

Methods and devices for navigating lists of items using multiple displays are described. An example method is implemented on an electronic device having a first display. The method includes displaying a list of items on the first display, at least one of the list of items having respective associated content not visible in the displayed list of items; and while displaying the list of items on the first display, sending the associated content for one or more of the at least one item to a second display for display on the second display.

Claims

1. A method in an electronic device, the electronic device having a first display, the method comprising:

displaying a list of items on the first display, at least one of the items of the list of items having respective associated content not visible in the displayed list of items; and

while displaying the list of items on the first display, sending the associated content for one or more of the at least one item to a second display for display on the second display.

2. The method of claim 1, wherein the associated content for the one or more of the at least one item is displayed as a preview of that associated content.

3. The method of claim 2, wherein the list of items displayed on the first display is a subset of a scrollable list of items, the method further comprising:

receiving a scrolling command to scroll the scrollable list of items;

in response to receiving the scrolling command, scrolling the scrollable list of items, and

while scrolling the scrollable list of items, initiating scrolling of the corresponding previews of the content associated with the one or more of the at least one item on the second display.

4. The method of claim 3, wherein scrolling the scrollable list of items includes:

determining that a rate of scrolling of the scrollable list of items is greater than a pre-determined threshold,

identifying one or more new items from the scrollable list that will be displayed when the rate of scrolling drops below the pre-determined threshold, and

sending the content associated with the identified one or more new items to the second display.

5. The method of claim 2, wherein the displayed preview of the content includes at least a portion of the associated content.

6. The method of claim 2, further comprising displaying on the second display one or more previews, each preview displaying respective associated content received from the electronic device.

7. The method of claim 6, wherein displaying a list of items on the first display and displaying on the second display includes applying a graphical feature to one of the items and its associated preview to indicate the association between that item and its associated preview.

8. The method of claim 6, wherein displaying on the second display is not conditional upon receipt of a selection of items on the first display corresponding to the one or more previews.

9. The method of claim 1, wherein the second display forms part of another electronic device, and the method further comprising establishing a connection with the other electronic device.

10. The method of claim 9, wherein the list of items displayed on the first display is a subset of a scrollable list of items, and the method further comprising sending, to the other electronic device for pre-caching, associated content for some of the items from the scrollable list of items not yet displayed in the first display.

11. The method of claim 9, further comprising establishing a connection with the other electronic device.

12. The method of claim 1, wherein the sending is based on identifying the one or more of the at least one item being displayed on the first display and is not conditional on user selection of the one or more of the at least one item.

13. The method of claim 1, wherein the list of items is associated with a messaging application, each item of the list of items is a message identifier, and the content associated with each item is a body of a message.

14. An electronic device comprising:

a first display;

a processor coupled to the first display;

and wherein the electronic device is configured to;

display a list of items on the first display, at least one of the items of the list of items having respective associated content not visible in the displayed list of items; and

while displaying the list of items on the first display, send the associated content for one or more of the at least one item to a second display for display on the second display.

15. The electronic device of claim 14, wherein the associated content for the one or more of the at least one item is displayed as a preview of that associated content.

16. The electronic device of claim 15, wherein the list of items displayed on the first display is a subset of a scrollable list of items, and wherein the electronic device is further configured to:

receive, via the input interface, a scrolling command to scroll the scrollable list of items;

in response to receiving the scrolling command, scroll the scrollable list of items, and

while scrolling the scrollable list of items, initiate scrolling of the corresponding previews of the content associated with the one or more of the at least one item on the second display.

17. The electronic device of claim 16, wherein scrolling the scrollable list of items includes:

determining that a rate of scrolling of the scrollable list of items is greater than a pre-determined threshold,

identifying one or more new items from the scrollable list that will be displayed when the rate of scrolling drops below the pre-determined threshold, and

sending the content associated with the identified one or more new items to the second display.

18. The electronic device of claim 14, wherein the displayed preview of the content includes at least a portion of the associated content.

19. The electronic device of claim 14, further configured to display on the second display one or more previews, each preview displaying respective associated content received from the electronic device.

20. A non-transitory computer-readable storage medium comprising computer executable instructions which, when executed, configure a processor to:

display a list of items on a first display of an electronic device, at least one of the items of the list of items having respective associated content not visible in the displayed list of items; and

while displaying the list of items on the first display, send the associated content for one or more of the at least one item to a second display for display on the second display.
