TALK OUTLINE • PREVIOUS EXPERIENCE • CNV and DCNV extraction and recognition • EEG controlled devices • ONGOING RESEARCH • representation of knowledge of the environment in autonomous agents • Behavior of human subjects in simple virtual environments • WG3 MK ROLE IN COST B27 WG3 COST B27 MK national report, Istanbul, September 3. 2005

  3. Contingent Negative Variation (CNV) Experimental setup for the CNV experiments WG3 COST B27 MK national report, Istanbul, September 3. 2005

  4. Contingent Negative Variation (CNV) Typical CNV wave recorded from Cz electrode. By convention negative EEG values are up WG3 COST B27 MK national report, Istanbul, September 3. 2005

  5. CNV extraction using classical averaging WG3 COST B27 MK national report, Istanbul, September 3. 2005

  6. DYNAMIC CNV EXPERIMENTAL SETUP (DCNV) WG3 COST B27 MK national report, Istanbul, September 3. 2005
