ECE Ph.D. student Kathy Brigham and her adviser, Professor Vijayakumar Bhagavatula, earned the Best Innovative Topic Paper Award at the IEEE Fourth International Conference on Biometrics: Theory, Applications and Systems (BTAS) 2010 for their paper, "Subject Identification From Electroencephalogram (EEG) Signals During Imagined Speech." Held in Arlington, Va., earlier this fall, the conference is the premier research meeting focused on biometrics.
In their paper, Brigham and Kumar add to the body of research on interpreting EEG signals for imagined speech for silent communication, which has a variety of uses, such as Brain Computer Interface (BCI) applications to assist those physically unable to talk or in situations where audible communication is undesirable (such as covert military operations). Brigham's paper investigated the potential for using imagined speech EEG signals to identify subjects - a technique that could be used to retrieve user profiles or create a more secure environment in general during silent communication. Her results show that subjects can be classified to a high degree of accuracy even under varying conditions of the imagined speech (e.g., different syllables or rhythms, or sessions at different times).
The award was sponsored by Honeywell and includes a cash prize. For more on the conference, visit www.cse.nd.edu/BTAS_10/.
