Abstract: There is disclosed an interactive whiteboard system including a mobile stand, an interactive surface, and a projector, wherein the mobile stand is adapted to support the interactive surface, and wherein the mobile stand further includes a support arm which extends away from the plane of the interactive surface to support a projector head of the projector in a position in front of the interactive surface, wherein the projector head is rotatable relative to the support arm between a use position in which images projected from the projector head are displayed on the interactive display surface and a non-use position in which the dimension of the system in a direction perpendicular to the plane of the interactive surface is reduced in the non-use position compared to the said dimension in the use position.
