An actuated support frame for transmitting motion to a seat with respect to a ground as a function of motion signals associated with video output, comprises a frame. The frame is expandable/retractable along translational degrees of freedom. Support surfaces are provided on the frame. The support surfaces are displaceable with respect to one another by expansion/retraction of the frame so as to be sized to support a seat. Actuators are provided between the frame and the ground. The actuators receive signals and selectively displace the frame with respect to the ground in synchronization with a video output, whereby a seat supported on the frame is displaceable within the frame. A method for installing a seating system of a motion simulator system is also provided.
