Slides of my invited plenary talk at 10th European Congress on Telepathology and 4th International Congress on Virtual Microscopy, in Vilnius, Lithuania, 1-3 July 2010.

1. Towards second generation expert systems in telepathology for aid in diagnosis Prof. Dr. Touradj Ebrahimi [email_address]

10. Explicit versus implicit interaction

16. Three image sets in three different experiments

18. Overview of experiments environment Matlab Code start at T* EEG Acquisition device Eye Tracker Image Presentation Software

20. Operator performing experiments

21. EEG signal acquisition The average signal from the T7 and T8 electrodes was used for referencing to achieve full 80 dB CMRR.

23. Influence of the rate (experiment 1) Averaged signals of PZ electrodes for different image display rates (top left: 500 ms to bottom right: 50 ms). Horizontal axis is the time after stimulus onset and vertical axis amplitude of the P300 signal . Target (red) , Non-Target (blue) stimulus

24. Influence of the position of EEG sensor (experiment 1) Averaged signal target (red) and non-target (blue) taken from electrodes P3, PZ, PO3, PO4, P4, CZ (top left to bottom right). Horizontal axis corresponds to the time after the stimulus onset and vertical axis shows the amplitude of the P300 signal .

25. Specialist versus naïve subjects (experiment 3) Averaged PZ electrodes for subjects. Top left: specialist, Others: naïve subjects. Horizontal axis is the time after stimulus onset and vertical axis amplitude of the P300 signal . Scientifically interesting Target (red) , Non-Target (blue) , Non-obvious target (dashed black) stimulus.
