ABSTRACT

A set of twenty icons for fingerprint scanning systems designed by National Institute of Standard and Technology (""liST) was evaluated through questionnaires. Results indicated that the recognition rates of approximately half of these icons were significantly lower than the standard rate of 66.7% stipulated by International Organization for Standard (ISO). Four icons witli low recognition rates were selected for redesign. Three alternatives were designed for each of the four icons to access the conformability to their intended meanings against originals. Results showed that the conformabilities of three out of four original icons have been improved by replacing them with their alternative designs. The findings of this study should be able to provide relevant icon design suggestions for enhancing the usability of fingerprint scanning systems.
