Axiomatic Design for Biometric Icons
Well-designed icons should be visually distinctive and appropriately represent their intended meanings. Through the axiomatic design method, potential design issues about the recognition of a set of biometric icons for a fingerprint capture device have been identified. Two possible solutions, icon redesign and provision of procedure instruction, were proposed. A 2x2 ANOVA experiment was designed to test the main and interaction effects of the two solutions on eighty participants’ icon recognition rate. Results showed that either redesigning the icons or providing the procedure instruction could significantly enhance the icon recognition rate. Furthermore, significant interaction effect indicated that the benefit of instruction was minor if redesigned icons were applied. From the perspective of human factors, icon redesign according to the axiomatic design principles may be a predominant solution.
