The Sensorium: A Multimodal Neurofeedback Environment

Figure 2

General overview of the multisensory and multimedial feedback system. The TTD software is installed on a PC and is used for data acquisition and preprocessing of the EEG and peripheral signals such as the Electrocardiogram (ECG), skin conductance, or respiration. It is also capable of on-line brain state classification. The SymPOSER module transforms the signals into sound and light. For driving an external feedback environment the sound should be presented over a stereo speaker system and the light control signal is sent to a DMX control unit for driving any studio lighting system.
