Abstract (en)
[origin: WO2004023382A1] The invention relates to a biometric writing system comprising a stylus housing (3) for carrying out hand-guided movements on a pad (4), at least one microphone (5), which is integrated in the stylus housing (3) and provided for acoustically recording acoustic signals that are produced by the hand-guided movements. The inventive biometric writing system also comprises a data processing unit (11) for calculating biometric data according to the recorded acoustic signals.
