Users of biometric systems have expanded from traditional law enforcement operators to the general population with diverse backgrounds. Past research has shown that usability is improved when users received real-time system feedback regarding their hand positioning and how to correct any undesirable positions. Users can perform fingerprint self- captures successfully by following real-time textual corrective instructions as reported by Choong, Theofanos and Guan. This paper builds on their work with two research questions: what symbols are best conveying the textual instructions, and, can diverse international users perform ten-print fingerprint self-captures following graphics-only guidance with no language? We developed a prototype biometric self-capture kiosk to investigate our research questions. A total of 140 subjects participated in two controlled experiments. The findings show that the self-capture prototype is a highly usable system with evidence of great potentials for supporting diverse users. By following the real-time, graphics-only guidance, participants quickly learned, felt comfortable and confident to capture their own fingerprints without any assistance.
