The trends that CES discloses for this year are: 3D, touch-able, visual retrieval, and voice control as the frontiers of UI for 2012. This all makes sense and is somewhat confirmed by the recent patent Apple disclosed about a “three-dimensional (“3D”) display environment for mobile device”, let alone the recent Siri introduction, with its lights and shadows.
Now, those (3D, touch, voice, visual) are just words that appeal to our minds, but they are still far from ensuring a User Experience which is pleasant and effective (as the Siri case itself is there to show). Touch technologies were there well before the iPhone made its appearance, still it was only with the iPhone introduction that they got to the level of refinedness, coherence, and completeness that made them turbo-boom in the market.
Ideas are ok, what matters most is how they are made into real things.
