For a while now, developers have been struggling to build displays that could run 3D stereoscopic images without the need for specialized glasses. Sharp have been working on it for a while now. Toshiba are already announcing the specifics for their display.
NTT DoCoMo are not only showcasing a glass-free 3D display, but it is also a 3D display with haptic feedback. At CEATEC, NTT DoCoMo presented a prototype display about the size of the one on a smart-phone, that does not only render 3D images without the need for glasses, but two stereoscopic cameras placed right above the screen can detect the position of a stylus in 3D.
The application that runs on this gadget has a chameleon sitting on a branch.  As you move the stylus towards a point of the screen – no touching needed – the chameleon will strike its tongue out towards the tip of the stylus. When the chameleon strikes, the stylus vibrates.

This mimics real life perfectly: not only do you see the chameleon in 3D, but it can perceive you in 3D as well, so you interact in a full 3D environment.
Great idea for the gaming community to pick up on. Unfortunately, the product is just a prototype and it still needs some work. Check out the video to get a better idea of what this prototype is capable of.
