A multi-board presentation system has a plurality of interactive boards connected to and controlled by separate computers that are in communication with one another through a server. The multi-board system utilizes a multi-machine interface that runs concurrently on each interactive board/computer providing heterogeneous input and output capabilities. Each interactive board may be assigned or associated with an offset value that allows for various schemes of display of panels of content on the different interactive boards. Such schemes may be operated manually by a moderator or automatically via the system. A portable interactive tablet may be part of the multi-board system which interfaces with the plurality of interactive boards through the server. The present multi-board system may also include a plurality of interactive participant tablets that are in communication with the array of interactive boards. Each interactive user tablet allows the participant to select which panel of content to display on their interactive tablet. Each interactive participant tablet allows the participant to synchronize display of one or panels of content thereon as displayed on one or more of the interactive boards. Moreover, each interactive participant tablet accepts participant input that is displayable on an interactive board displaying the same panel of content, with the participant input optionally being masked or obscured.
