In this paper, we discuss the relative importance of different signal types from the viewpoint of on-line signature verification. The signals that are evaluated are forces on the writing devices tip in 3 dimensions and angles of its shaft relative to the writing surface in 2 dimensions. These signals are captured by the SmartPenTM, which is the heart of a completely operational biometric identity verification system. The results of the experiments that have been carried out are not just interesting for this peculiar identity verification system, since they allow to evaluate the implications of potential simplifications of the SmartPenTM-concept, but they are undoubtedly useful to future developers of on-line signature verification systems.
