DDR Arcade Versions?

Question

I know there must be 3 ways to play DDR.
You know how they have Karaoke Revolution now.

They have DDR for the dance pad
DDR where you use the hands
and this one DDR i saw where it looks like you stand in the middle and it catches motions, i guess..
Could anyone tell me if those DDR versions go under a different name?

Thanks. I hope it wasn't too confusing.
