1. A display system that detects the point of touch and three-dimensional direction of a pressure 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 and the real object can be seen through the transparent surface; a plurality of sensors wherein at least one sensor of the plurality of sensors is in touch with one face of the six faces to detect the value of the force exerted on the one face due to the pressure; a microprocessor that receives the output of the plurality of sensors 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 object; and a presentation unit that manipulates a camera to rotate horizontally or vertically according to the three-dimensional direction wherein the camera is a camera of a head mounted computer display and the surface is a surface of the head mounted computer display highlighting a spot on the real object corresponding to the point of touch and three-dimensional direction.
