We tested seven different EEG electrode systems according user centered, operator centered and technical aspects. In the initial testing phase we focused on technical aspects and more simple experimental tasks. The results of these first tests were used to select the best three systems in an advanced testing phase. In this second testing phase a P300 based BCI was used to navigate through a multimedia player, selecting music and video clips. The results showed that each of the systems has its advantages and disadvantages which should be considered when planning future NeuroIS studies using EEG.
