Hi there,
I wonder how can "Just Dance" detect my whole body's motion with just one wii remote? Does it rely on the sensor bar to scan my body?
I found it is really able to detect my motion precisely, not just my hand holding the wii remote, but my another hand, my legs and even my head. How can it do that?

Thank you.

Sorry, I can't answer the main question (never played Just Dance anyway). What I can tell is that the name "Sensor Bar" is misleading. This thing does not scan anything; it is not a sensor but a lamp. Nothing more than a few infrared LEDs (take a photo of the sensor bar with a digital camera or smartphone while the Wii is on – the light should be visible). There is a light sensor inside the Wii remote that can tell in what angle the remote is pointed to the LEDs.

Basically, it extrapolates your movement from the movement of the wiimote. It isn't able to see anything else, they likely just chose the dance moves very carefully, for that to work.

Its not working so well for the first game in the series.

Oh thanks for your detail information. I got it now.

But when I exactly match its movements (eg: Jump, kick), I get higher score. So I wonder how it knows my whole body movement..

basically, the moves just naturally go with very certain arm movements. for a kick or a jump, you use your arms to brace yourself, balance yourself in a certain way and that's the motion they're looking for.

It doesn't detect the whole body. What Just Dance does is just read the gravity/accelerometer readings for X, Y and Z and compares it to saved data in the game recorded from testers. If it matches close enough, it's a perfect/good.

Only the Kinect Just Dance and the PS3/PS4 Just Dance tracks the whole body.

    I would absolutely love it if Apple started licensing the OS out, like Microsoft does, though.
    Still love the OS, just quite ambivalent about the OS' owner.
