Abstract

Although there is widespread deployment of biometric technologies such as fingerprint systems, little attention is being paid to the human-computer interaction that such technologies involved. This report presents the results of a study that examined the affect of the height of the sensor on the quality and the time required to collect prints. The study was designed to answer three questions: 1.Does work surface height affect the time required to capture fingerprint images? 2.Does work surface height affect the quality of the captured images? 3.Do users prefer or are more comfortable at a particular work surface height? The results can be reduced to the following recommendations for a ten-print capture sequence with a six inch high sensor ?a counter height of 36 inches (914mm) gives the fastest performance. ?a counter height of 26 or 32 inches (660mm) gives the best quality performance. ?a counter height of 32 inches (813mm) is the most comfortable for users. ?starting a capture sequence with the right slap was most efficient.I
