Author(s)
Yee-Yin Choong, Mary Theofanos, Brian Stanton
During the InterNational Committee for Information Technology Standards (INCITS) M1 task group meetings in 2008, it was recognized that there is a need for a symbol to represent that any biometrics (fingerprint, iris, photo, etc.) are in use. The symbol is

Does the Angle of a Fingerprint Scanner Affect User Performance?

September 22, 2008
Author(s)
Mary F. Theofanos, Ross J. Micheals, Shahram Orandi, Brian C. Stanton, Nien F. Zhang, Charles L. Sheppard

Assessing Face Acquisition

September 15, 2008
Author(s)
Mary F. Theofanos, Brian C. Stanton, Charles L. Sheppard, Ross J. Micheals, John M. Libert, Shahram Orandi
The requirements necessary for taking a successful face picture are arguably the least constrained of any biometric. The camera must be operational, and the subject must be illuminated sufficiently and facing the camera. Yet, a significant portion of the

Abstract The requirements necessary for taking a successful face picture are arguably the least constrained of any biometric. The camera must be operational, and the subject must be illuminated sufficiently & facing the camera. Yet, a significant portion

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
