yeah the DS3 will be kind of awkward when being used with one hand but you can use it.
voice recognition is just the software using the mic's on the eye. i used the eye for tom clancy's end war instead of a headset.
there was also a video where Anton (one of the people who designed the move) mention the features. I will add a link for that when I find it.
Thats some interesting Tech there no doubt. Thanks for the link and info.
Im not a fan of head tracking because if you turn your head your not looking at the tv anymore. But voice recognition seems cool.
