User Interfaces for Volumetric Displays
March 2001 (vol. 34 no. 3)
pp. 37-45

Although still in the prototype stage, three-dimensional volumetric displays present unique interface challenges. Current display technologies limit our ability to view and interact with 3D computer graphics because we typically view 3D data on a 2D system that cannot display the depth dimension.

Volumetric displays hold the promise of enhancing 3D graphics realism by providing all the depth cues humans require.

Incorporating everyday gestures to delineate subportions of the working volume, the authors use physical mockups to consider potentially viable displays and associated input mechanisms. Researchers can use high-fidelity mockups and props to glimpse the future with minimal prototyping effort, before the display and input technologies mature.

The authors' mockups elucidate a range of design challenges and volumetric-display opportunities, revealing a rich set of alternative user-interface design options. However, more evaluation must be conducted before it's possible to harness the full potential of interacting with volumetric displays.
