Tileable, coplanar, flat-panel 3-D display with tactile and audio interfaces
A method and system for a scalable multi-sense user experience are disclosed. A three-dimensional (“3-D”) display is disposed behind a slit plane comprising slits and ultrasonic transducers. Light from the 3-D display passes through the slits in the slit plane to generate a 3-D image. The ultrasonic transducers on the front of the slit plane, i.e., opposite the side where the 3-D display is disposed, generate directed acoustic field and/or a formed tactile field. Because the generating components for all three senses, i.e., visual, audio, and tactile, are coplanar, units may be tiled and thereby scaled to generate larger multi-sense experiences.
