A method of selecting information to be displayed by a first collaborative system, the first collaborative system being in communication with a second collaborative system, the first collaborative system having a first drawing surface for drawing on by a first user local to the first collaborative system, and the second collaborative system having a second drawing surface for drawing on by a second user local to the second collaborative system, the method comprising: receiving, by a controller at the first collaborative system: a first information stream comprising a digital representation of a drawing drawn by the first user and captured on the drawing surface of the first collaborative system; a second information stream comprising a video stream captured at the first collaborative system; a third information stream comprising a digital representation of a drawing drawn by the second user and captured on the drawing surface of the second collaborative system; a fourth information stream comprising a video stream captured at the second collaborative system; and selection information comprising positional information indicative of the second user's position; repeatedly determining whether the second user is positioned within a certain distance of the second drawing surface, and if it is determined that the second user is positioned within the certain distance of the second drawing surface, generating, by the controller, a signal including a first set of the information streams; otherwise, generating a signal including a second, different, set of the information streams; and causing the generated signal to be output such that information corresponding to the set of information streams included in the signal is displayed on the drawing surface of the first collaborative system; wherein the first set of information streams comprises the first and third information streams and the second set of information streams comprises the second and fourth information streams. receiving, by a controller at the first collaborative system: a first information stream comprising a digital representation of a drawing drawn by the first user and captured on the drawing surface of the first collaborative system; a second information stream comprising a video stream captured at the first collaborative system; a third information stream comprising a digital representation of a drawing drawn by the second user and captured on the drawing surface of the second collaborative system; a fourth information stream comprising a video stream captured at the second collaborative system; and selection information comprising positional information indicative of the second user's position; a first information stream comprising a digital representation of a drawing drawn by the first user and captured on the drawing surface of the first collaborative system; a second information stream comprising a video stream captured at the first collaborative system; a third information stream comprising a digital representation of a drawing drawn by the second user and captured on the drawing surface of the second collaborative system; a fourth information stream comprising a video stream captured at the second collaborative system; and selection information comprising positional information indicative of the second user's position; repeatedly determining whether the second user is positioned within a certain distance of the second drawing surface, and if it is determined that the second user is positioned within the certain distance of the second drawing surface, generating, by the controller, a signal including a first set of the information streams; otherwise, generating a signal including a second, different, set of the information streams; and causing the generated signal to be output such that information corresponding to the set of information streams included in the signal is displayed on the drawing surface of the first collaborative system; wherein the first set of information streams comprises the first and third information streams and the second set of information streams comprises the second and fourth information streams.
