Abstract

A human/machine interface system that presents information in a three-dimensional and visual form and is optionally capable of receiving input.

The Three-Dimensional Display comprises a display shape with visual displays that is movable to provide visual and three-dimensional representative imagery. An optional method for sensing input can be added to allow user interaction with the display.

A number of these displays could be arrayed together and driven by appropriate circuitry to present to the user visual and physical representation upon which the user can act to communicate back to the machine.
