POSTURE, POSITION & BIOMETRICS: GUIDELINES FOR SELF-SERVICE TECHNOLOGY

Biometric technology provides an opportunity to improve identification security across a range of different transactions. This user-centred investigation examined the effect of position on the usability and accessibility of biometric devices. Using an approach based upon ISO 9241-11 Standard for Usability, the performance of fingerprint and palm vein technology was assessed for a self service context. Postures were also recorded and scored using the RULA posture assessment tool. The devices was tested at three heights, 1000 mm, I 100 mm and 1200 mm and three angles 0 degrees, 15 degrees and 45 degrees. Device position was found to significantly affect participants' satisfaction ratings and the postures they adopted. The palm vein device out-performed the fingerprint device. This investigation shows how the physical placement of biometric devices can affect the systems' performance, and has implications for its use in the self service environment.
