The non-interacting participants follow the changes made by the interacting participant but maintain the ability to take control of their viewport. The systems and methods introduce the concept of an area of interest (AOI), which is a region of the canvas that contains changes or modifications. The AOI relies on a notion of an active user. An active user is a participant that performs an action on the whiteboard. In order for the other participants to view and be aware of changes made to the whiteboard by the active user, the viewport of each device is automatically mapped to contain the AOI. ## Claims ### Claim 1 A method comprising: connecting, by a first device associated with a first user, to a virtual meeting space environment to which at least a second device, associated with a second user, is connected;
