Summary: The commutation relations, uncertainty relations, and spectra of position and momentum operators are studied within the framework of quantum group symmetric Heisenberg algebras and their (Bargmann) Fock representations. As an effect of the underlying noncommutative geometry, a length and a momentum scale appear, leading to the existence of nonzero minimal uncertainties in the positions and momenta. The usual quantum mechanical behavior is recovered as a limit case for not too small and not too large distances and momenta.
