Why 3D User Interfaces? <ul><li>Increase user satisfaction. </li></ul><ul><li>Improve cognitive perception </li></ul><ul><li>Indices sense of (tele)presence </li></ul><ul><li>3DUIs are not automatically superior or inferior to 2DUIs. </li></ul>ITEA UsiXML project #08026, 2009-2012

5.
Why NOT 3D User Interfaces? <ul><li>Decrease user performance </li></ul><ul><li>Increase manipulation complexity for an average user </li></ul><ul><li>Are not appropriate for any task </li></ul><ul><li>Are hard to evaluate for their usability </li></ul>ITEA UsiXML project #08026, 2009-2012

6.
Focus <ul><li>Information systems (data, process, resources) </li></ul><ul><li>Administrative tasks (routine, repetition) </li></ul><ul><li>Interaction styles (form filling, multi-windowing, direct manipulation, iconic interaction, graphic interaction, multimedia interaction, and 3DUIs) </li></ul>ITEA UsiXML project #08026, 2009-2012

7.
<ul><li>3D UI as an specialization of 2D </li></ul><ul><li>Benefits: </li></ul><ul><ul><li>Relying on existing 2D UI by specializing </li></ul></ul><ul><ul><li>Factoring out 3D vs 2D UIs </li></ul></ul>ITEA UsiXML project #08026, 2009-2012 VS.

Shortcomings: <ul><li>Adding another modality breaks the factoring out </li></ul><ul><li>Hard to provide multiple representations of 3D objects </li></ul><ul><li>No full separation of concerns </li></ul>ITEA UsiXML project #08026, 2009-2012
