The three-dimensional imagery available from holography can provide additional information to a business machine operator and visual interest to encourage use of the display. Both of these factors can enhance the functionality of the user interface. This paper describes several display concepts that use holographic images for man-machine interfaces and the implementation of some of these ideas. A hybrid display that incorporates a holographic image and a liquid crystal display has been developed.
