Abstract
A mobile interactive presentation and collaboration system having a projector carriage is positioned rearward of a screen assembly such that a projector positioned on the projector carriage operates as a counterweight balancing the screen assembly to prevent die screen assembly from tipping forward. The projector carriage is positioned at the base of the screen assembly to lower the center of gravity of the system to further improve the stability of tire system.

A mobile interactive presentation and collaboration system, comprising:
- a cart chassis having an elongated front member and at least two side members projecting rearward from the front member to support the front member in a front to back direction;
- a screen assembly having two side supports projecting vertically from the cart chassis and supporting a rear projection screen in a generally vertical orientation, wherein the rear projection screen comprises a front face and a rear face and positioned above the elongate front member and substantially forward of a midpoint of the side members of the cart chassis along the front to back direction;
- and
- a projector carriage defining a generally horizontal shelf for receiving a short throw projector, such that the short throw projector projects an image directly onto the rear face of the rear projection screen at a steep upwardly directed angle, wherein the projector carriage is positioned rearward from the rear projection screen at about the bottom of the rear projection screen such that the short throw projector counterweights the screen against tipping forward.
