Changes in Finger Preferences Over a 6 Week Period of Interaction

Abstract: The Human Biometric Systems Interaction (HBSI) is a field that focuses on user perceptions and preferences. This project is to establish whether the user is likely to change their preferred fingers after interacting with an optical fingerprint sensor over a time frame of 6 weeks.

Methodology: The methodology involves having subjects interact with a commercially available 500 dpi optical sensor to acquire 10 images from their three preferred fingers during week 1 of the experiment and then 3 images during subsequent interactions for 6 weeks. After the final image acquisition, the users will be asked to re-rank their preferred fingers. In order to evaluate the changes in preference from pre to post interaction, a series of Chi-Squared tests will be run on the three finger preference rankings.
