Perceptualization of biomedical data - An experimental environment for visualization and sonification of brain electrical activity

Complex experiments require sophisticated visualization of a large number of parameters. However, physiological characteristics of human perception limit the number of visualized parameters and dynamics. Multimodal data presentation can increase throughput, introduce new data streams, and improve temporal resolution. Multimodal parameters must be set to maximize the distance of changes in the perceptual domains. Sonification, as a second presentation modality is discussed, implementing it in 3D electroencephalography to render synesthetic extension of a selected data channel or to introduce new composite parameters.
