3 Beat

Degrees of freedom: 3*

This trick is essentially moving a circle between two planes, so there are 3 degrees of freedom (2 for circular motion within Y-Z plane, 1 for moving the circle back and forth along the X-axis in the global frame)

*Assuming poi is a point mass. For more information on planes and this assumption, see the technical info page here

Expected and observed frequencies:

One fundamental frequency is observed at a slightly faster rate of ~1.5 Hz, which can be attributed to the fact that 3 cycles must now be completed within a single trick. This signal also has a higher amount of noise due to hands crossing across the body and increased wrist motion

Equations to characterize trick:

• X = sin(t)
• Y = cos(3t)
• Z = sin(3t)
