AR jam: Calibration and song changing

Before using the Ur hand tracker, we'll have to calibrate the hand. We can easily change the song as well.

Calibration Flow

After building the scene, you'll notice a calibrate button in the top left corner of the screen. A calibration process calculates a per-user "hand scale" which is essential for accurate 3D hand pose tracking.

After clicking the button, place your hand on a flat surface, point your device's camera at your hand, and move it forward and backward. You'll notice the calibration percentage going up, and when ready, the dot next to the hand button turns green.

That's it. You are all set!

Changing the song

Oh, and one last tip: changing the song is easy. Use one of the many free AI tools to separate any song you like into different instruments and replace the channels in AppConfig.

The full Unity project can be downloaded from GitHub.
