1) 1
2) 2
3) 3
4) 4

Answer 1

Real-time motion tracking systems typically have three degrees of freedom, tracking movement along the x, y, and z axes.

Step-by-step explanation:

Real-time motion tracking systems can track motion in up to three degrees of freedom (3 DOF). These systems measure movement along the three spatial dimensions: the x-axis (left and right), the y-axis (up and down), and the z-axis (forward and backward). In addition to the linear movements, motion tracking can also detect rotations around each of these three axes, which is sometimes referred to as six degrees of freedom (6 DOF) for more advanced systems. However, for most practical purposes and basic applications, three degrees of freedom are essential.
