Usability and Biometrics: Ensuring Successful Biometric Systems

June 11, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Cari Wolfson
The National Institute of Standards and Technology (NIST)Visualization and Usability Gropu initiated a Usability and Biometrics effort to focus on the users and human factors of biometric systems. The goal of this effort has been to conduct research to

How the User can Improve Fingerprint Image Quality

May 12, 2008
Author(s)
Mary F. Theofanos, Ross J. Micheals, Shahram Orandi, Brian C. Stanton, Nien F. Zhang
Traditionally the biometric field has viewed the user as a passive source of the biometric sample rather than an interactive component of the biometric system. But fingerprint image quality is highly dependent on the human computer interaction and

Usability Testing of Height and Angles of Ten-Print Fingerprint Capture

May 11, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Charles L. Sheppard, Ross J. Micheals, John W. Wydler II, Nien F. Zhang, Lawrence Nadel, William Rubin
As the deployment of biometric technologies such as fingerprints has become more widespread in government applications there is an increased awareness of the human-computer interaction that such technologies involve. User behavior can impact operational

A Study of Users with Visual Disabilities and a Fingerprint Process

April 10, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Charles L. Sheppard
The Department of Homeland Security¿s (DHS) United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is a biometrically-enhanced identification system primarily situated at border points of entry such as airports and seaports

Making Biometric Systems Usable Let's Not Forget the User

December 31, 2007
Author(s)
Mary F. Theofanos, Brian C. Stanton
The use of physical identifiable characteristics (biometrics) in border and transportation security has increased since 9/11. Currently, the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program collects a right and left index

A Framework for the Evaluation of Pervasive Information Systems

December 28, 2007
Author(s)
Jean C. Scholtz, Mary F. Theofanos, Sunny Consolvo
In this chapter we present a framework of areas of evaluation for pervasive information systems along with metrics and examples from the literature. We review a number of methodologies that have been used in evaluation. A case study of an evaluation using

Usability Testing of Ten-Print Fingerprint Capture

October 8, 2007
Author(s)
Brian C. Stanton, Mary F. Theofanos, Shahram Orandi, Ross J. Micheals, Nien F. Zhang
Despite the increased deployment of biometric technologies in United States government applications, not enough attention is being paid to the human factors that such technologies involve. The use of biometric applications will be unfamiliar to many users

Biometric Systematic uncertatinty and the User

September 12, 2007
Author(s)
Mary F. Theofanos, Ross J. Micheals, Shahram Orandi, Brian C. Stanton
Often biometric technology and system evaluators are concerned with capturing accurate performance estimates that predict performance for target populations of interest. Occasionally, predictions, and perhaps adjustments, for subpopulations based on

Effects of Scanner Height on Fingerprint Capture

June 27, 2007
Author(s)
Mary Theofanos, Shahram Orandi, Ross J. Micheals, Brian Stanton, Nien F. Zhang
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
