A 3-D Chameleon Strikes Back
From televisions, video cameras, cellphone displays and videogame consoles, 3-D is spreading into every category.
In the near future, it could become a common feature on all kinds of electronic devices. So what’s next?
NTT DoCoMo Inc. reckons that the next step is to “feel” 3-D images rather than just look at them.
The Japanese mobile carrier’s booth at the Combined Exhibition of Advanced Technologies, or Ceatec, has tiny 3-D screens on display. Each one, about the size of a mobile handset, shows a chameleon perched on a tree, which you can see in 3-D without glasses.
Then you hold a special pen and slowly move it toward the animal. When the pen comes close, the chameleon shoots out its tongue. You can feel the tongue hitting the tip of the pen in your hand.
So how does it work?
