1. A display system that detects the point of touch and three-dimensional direction of a force exerted by an object on a surface to select a corresponding spot on a real object, wherein the display system is comprised of; a touching cube with six faces wherein each face of the six faces is a transparent surface wherein a real object can be seen through the transparent surface; a sensing unit that detects the simultaneous movements of the touching cube relative to the x-axis, the y-axis, and the z-axis when a force is exerted by an object at a point of touch on the touching cube; a microprocessor that receives the data of the simultaneous movements from the sensing unit to determine the point of touch and the three-dimensional direction; a database that associates each point of touch and three-dimensional direction with a corresponding spot on the real objects; and a presentation unit that highlights the spot of the real object that is corresponding to current point of touch and three-dimensional direction.
