1. A holographic projection unit, comprising:
a frame structure;
a touch screen supported by the frame structure;
a projector having a first end coupled to the frame structure by a first hinge element, the projector including a projector screen for generating images;
a semi-reflective element coupled to the frame structure by a second hinge element, the reflective element being moveable between an open position and a closed position wherein the semi-reflective element is oriented to reflect light from the images when in the open position in order to create volumetric images perceptible to a user of the holographic projection unit; and
a slide hinge system disposed at a second end of the projector, the slide hinge system including a positioning member through which the reflective element is translated when moving between the open position and a closed position.
