These days it seems that 3D is becoming the norm. 3DTVs still aren't everyone's idea of what 3D should be like, but autostereoscopic devices like Nintendo's upcoming 3DS may help make such technology a bit more mainstream.
For now, 3D usually means some silly glasses that cost more than most people would ever want to pay for them, as well as gimmicky special effects that feature things constantly flying in the viewer's direction. However, it seems that Sony may also want to test it out with UI design.
Navigating around a menu in 3D, where the highlighted item seems to pop out at the viewer is an interesting idea. We aren't sure how practical it is, but it's a step past some of the recent movies we've seen.
Here's a description of the patent Sony hopes to obtain:
A display control device and method to generate stereoscopic images in a graphical user interface (GUI) to be displayed on a display panel. A pop-out amount unit or operation calculates a pop-out amount indicating a perceived distance that at least a portion of the stereoscopic image pops out into space from the display panel, and a display controller or control operation controls display of the stereoscopic image with the calculated amount of pop-out on the display panel.
