The term "sixaxis" is also used to refer to the motion-sensing technology in PlayStation 3 controllers. It is a contraction of "six axis", which refers to the ability to sense motion in all axes of the six degrees of freedom.[citation needed] The name is a misnomer because there are only three axes: X, Y, and Z, which allows six degrees of freedom (rotation about each axis and translation along each axis). It is also a palindrome.
