ABSTRACT

    Presented herein are techniques to enable zooming-in on shared content viewed from a mobile user device during an online conference/meeting. Specifically, these techniques enable a user to zoom in on the shared content using a single finger on his/her mobile device.

DETAILED DESCRIPTION

    Mobile devices have relatively small screens. Some mobile devices are of a size that they can be operated with one hand. When such a device is used in an online meeting, the user may want to zoom-in to view more details of the active/focus window/region. This can be difficult to do with one hand.

    Presented herein is a method to zoom-in an active window/region in an online meeting with a single finger when desktop sharing or application sharing (DS/AS) is occurring. The DS/AS function has a specific active/focus window/region. The most valuable region is the active/focus window/region. The method presented herein is directed to how to zoom-in on an active window, in a manner different than existing techniques which involve zooming in on the region based on a central region over which a finger is hovering.

The figures below illustrate an example.

    1. Mobile user is joining an online meeting and viewing the desktop/application share content of a presenter. The mobile user uses his left hand to hold the mobile device.

Presenter is sharing a window/application and discussing it with other meeting participants. This window/application is the active window/region. Fig. 1 below shows the screen on the mobile user's device and the blue region is the active region.

    2. The mobile user determines that this region is too small to view in detail, so he presses the screen with his left thumb on the screen for a while, such as approximately 1 second, and the system shows a green ring as shown in Fig. 2. The ring's initial position depends on the finger's initial position. Thus, the ring's position is not fixed.

    3. The mobile user slides along the ring as shown in Fig. 3 below, and the active region is zoomed-in.

    4. The mobile user slides further along the ring as below, causing more zoom-in of the active region. For the maximal magnification, refer to the section below: maximal magnification.

Implementation 1. Active (focus) window/region
Techniques for identifying the active region during DS/AS sharing are known.

Thus, details for such are not presented here. Rather, the emphasis here is on how to zoom-in active window/region with a single finger.


2. Central point of magnified (zoomed-in) active region

    The central point is based on the focus region, not the screen's center, as shown below in Fig. 5.
