The effect of Coulomb friction in a haptic interface was investigated for a simple positioning task. A custom 1-DOF interface was used, for which the Coulomb friction was varied from virtually zero to .70 N. The interface was operated using the wrist and fingers. Results based on the numbers of errors, completion times and subjective ratings show that, for this type of interface and task, Coulomb friction between .15 and .42 N is optimum.
