Abstract
A noncommutative *-algebra that generalizes the canonical commutation relations and that is covariant under the quantum groups SO q (3) or SO q(1, 3) is introduced. The generating elements of this algebra are hermitean and can be identified with coordinates, momenta and angular momenta. In addition a unitary scaling operator is part of the algebra.
