ABSTRACT

    A method is presented to allow an attendee to control the selective view of content during a desktop sharing session, allowing the attendee user to mask specified content being shared by a presenter.

DETAILED DESCRIPTION

    During an online meeting, some attendees may not be comfortable for some content presented during a desktop sharing session, while other attendees are comfortable seeing such content. The presenter may not attempt to mask it, or the content is in a recording playback which cannot be masked.

    Another similar example is follows. An instructor is sharing 2 pages of a course test on one screen. The left page on the share contains the questions, and the right page contains the answers. Every attendee can see both pages, but for some attendees, they do not want to see the answers because they would like the opportunity for a self-test.

    Presented herein is a method to solve this problem by allowing an attendee user to customize a desktop sharing view at his/her own device.

    This method involves two modes to let an online meeting user customize a selective view during a desktop sharing session.

1. Scan Mode

    
During the sharing, the mask region position is unknown beforehand, and it is changing with time. The user defines mask rules. A scan engine or function at the

attendee side will scan the shared content and dynamically mask the corresponding regions.

2. Static Mode

    
An attendee user draws a static region on the desktop sharing window. The content behind this region is masked.

    To implement it, in both of these two modes, there is a top layer on a user's desktop sharing window, which plays the mask role.

This top layer is referred to as a "Mask Layer".

Scan Mode in More Detail 1. Mask a region which is in a given shape and has special characteristics.

    For example, there is a floating advertisement window on the shared screen having a border with a circular shape, as shown in Fig. 1 below. The gray circle is the border.

    The content of this window is always changing, but there is one area in it that will not change, as shown in Fig. 2 below.

To mask this floating advertisement region, the following steps are performed: 1) Take a snapshot for the special image as in Fig. 2 with a built-in tool.

2) For the region to mask, create a mask rule, as shown in Fig. 3 below: Border is in shape of circle
Similar size with the floating advertisement window; and
Contains the special image.

The background grid is used for position adjustment for the special image in the region.

    When the mask rule is added, the scan engine/function will scan a shared frame before displaying it. A comparison is made of the special image given in the rule. If it finds a similari...
