EEG analysis in a telemedical virtual world

Telemedicine creates virtual medical collaborative environments. We propose here a novel concept of virtual medical devices (VMD) for telemedical appl ications. VMDs provide different views on biomedical recordings and efficie nt signal analysis. In this paper we present a telemedical EEG analysis env ironment based on virtual reality technologies. The same EEG signal/recordi ng could be viewed either as a waveform or as animated topographic maps on a 3D head model. In addition to visualization, sonification is used as a se condary presentation modality. The environment is based on a VRML head mode l animated with Java applets, and allows the use of standard web browser. ( C) 1999 Elsevier Science B.V. All rights reserved.
