Abstract: An apparatus (1) is configured to perform a test procedure for measuring vibrotactile perception of a human subject. The apparatus (1) comprises a vibration probe (5) with an end portion (5A) arranged for engagement by a body part (100), a contactless temperature sensor (13) arranged to face the body part (100) when engaged with the end portion (5 A), and a force sensor (7) coupled to the vibration probe (5). A control unit (10) prepares for the test procedure by computing, as a function of a first output signal (TIR) of the contactless temperature sensor (13) and/or a second output signal (f) of the force sensor (7), one or more characteristic parameters indicative of presence or absence of the body part (100). When presence of the body part (100) is indicated by the one or more characteristic parameters, the control unit (10) sets a current temperature of the body part (100) to a current temperature value given by the first output signal (TIR).
