Abstract

Techniques are presented herein to enable a first device participating in a conference session to adapt its displayed content being shared from a second device that has a larger display and can therefore display a larger area of content than the first device is capable of displaying. The first device has a first display and displays a portion of content being displayed on a second display of the second device that is being shared with the first device during an online conference session. The first device detects when a first change has occurred in the content that is outside of the portion displayed on the first display. A graphical element is displayed on the first display, the graphical element indicating that the first change has occurred in the content outside of the portion being displayed on the first device.

Claims

1. A method comprising:

displaying on a first display of a user device a portion of content being displayed on a second display of a presenter device that is sharing the content with the user device during an online conference session over a network;

detecting when a first change has occurred in the content that is outside of the portion displayed on the first display; and

displaying a graphical element on the first display in response to detecting that the first change has occurred in the content that is outside of the portion displayed on the first display, the graphical element including;

a changed region notification comprising at least one notification bar displayed along a border of the first display that is closest to a region in which the first change has occurred; and

a changed point indicator at a location in the at least one notification bar that is proximate to a location of the first change in content being displayed on the second display, the changed point indicator comprising at least one pointer, wherein a number of pointers in the changed point indicator is based on a number of changes associated with the changed point indicator.

2. The method of claim 1, wherein displaying the graphical element comprises:

displaying the at least one notification bar as first and second notification bars at a corner of intersecting borders of the portion of the content displayed on the first display, such that the first notification bar and the second notification bar are displayed on each intersecting border, and

displaying the changed point indicator at a location in either the first notification bar or the second notification bar that is proximate to a location of the first change in a corner region of the second display.

3. The method of claim 1, further comprising:

detecting user selection of the changed point indicator; and

displaying, in response to detecting user selection of the changed point indicator, on the user device content being displayed on the presenter device that contains the first change indicated by the changed point indicator.

4. The method of claim 3, further comprising:

removing the changed point indicator and first notification bar when displaying, on the user device, content being displayed on the presenter device that contains the first change indicated by the changed point indicator.

5. The method of claim 1, further comprising:

detecting a second change in the content being displayed on the second display outside of the portion displayed on the first display;

detecting whether the second change is in substantially the same location as the first change;

modifying the changed point indicator in response to detecting that the second change is in substantially the same location as the first change, such that the at least one pointer of the changed point indicator comprises at least two pointers; and

displaying, in response to detecting that the second change is not substantially the same location as the first change, a second changed point indicator indicating that the second change has occurred in the content outside of the portion being displayed, and the second changed point indicator being displayed at a location in the at least one notification bar that is proximate to a location of the second change in content being displayed on the second display.

6. The method of claim 1, further comprising:

removing from the first display, after a predetermined period of time has passed since the first change in content being displayed on the second display, the changed point indicator and the at least one notification bar.

7. The method of claim 1, wherein displaying the changed point indicator further comprises:

determining a center point of the first display;

determining an alignment point on the at least one bar that is linearly aligned with the location of the first change in the content being displayed on the second display and the center point of the first display; and

displaying the changed point indicator on the alignment point.

8. One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:

generate for display on a first display of a user device a portion of content being displayed on a second display of a presenter device that is being shared with the user device during an online conference session over a network;

detect when a first change has occurred in the content that is outside of the portion displayed on the first display; and

generate for display a graphical element on the first display in response to detecting that the first change has occurred in the content that is outside of the portion displayed on the first display, the graphical element including;

a changed region notification comprising at least one notification bar displayed along a border of the first display that is closest to a region in which the first change has occurred; and

a changed point indicator at a location in the at least one notification bar that is proximate to a location of the first change in the second display, the changed point indicator comprising at least one pointer, wherein a number of pointers in the changed point indicator is based on a number of changes associated with the changed point indicator.

9. The non-transitory computer readable storage media of claim 8, wherein instructions operable to generate for display the graphical element comprises instructions operable to generate for display:

the at least one notification bar as first and second notification bars at a corner of intersecting borders of the portion of the content displayed on the first display, such that the first notification bar and the second notification bar are displayed on each intersecting border, and the changed point indicator at a location in either the first notification bar or the second notification bar that is proximate to a location of the first change in a corner region of the second display.

10. The non-transitory computer readable storage media of claim 8, further comprising instructions operable to:

detect user selection of the changed point indicator; and

generate for display, in response to detecting user selection of the changed point indicator, on the user device content being displayed on the presenter device that contains the first change indicated by the changed point indicator.

11. The non-transitory computer readable storage media of claim 8, further comprising instructions operable to:

detect a second change in the content being displayed on the second display outside of the portion displayed on the first display;

detect whether the second change is in substantially the same location as the first change;

modify the changed point indicator in response to detecting that the second change is in substantially the same location as the first change, such that the at least one pointer of the changed point indicator comprises at least two pointers; and

display, in response to detecting that the second change is not substantially the same location as the first change, a second changed point indicator indicating that the second change has occurred in the content outside of the portion being displayed, and the second changed point indicator being displayed at a location in the at least one notification bar that is proximate to a location of the second change in content being displayed on the second display.

12. The non-transitory computer readable storage media of claim 8, wherein instructions operable to display the changed point indicator further comprises instructions operable to:

determine a center point of the first display;

determine an alignment point on the at least one notification bar that is linearly aligned with the location of the first change in the content being displayed on the second display and the center point of the first display; and
