I was watching some Youtube videos of TGS 2010 and I get the strange suspicion that Dance Masters (called Dance Evolution in Europe and Japan) will be more popular than Dance Central in Japan.
It seems to fit Japanese dancing styles better.
But the thing that caught my eye was the user interface. I think it might be better than the other Kinect games. Instead of having your hand be like a mouse cursor that you have to navigate around the screen and hold on screen buttons, it has hand positions for selection.
So if you want to select OK, you raise your hand straight up. As a result, they were navigating the UI fast! The girls were up and dancing right away.
Sure, the hold hand on a button to activate prevents accidental choices, but it takes like 1.5 seconds. and it's those little pauses that make a system feel unresponsive.
I guess with a new device, everyone is trying to figure out what is the best interface to use.
