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 applications. VMDs provide different views on biomedical recordings and efficient signal analysis. In this paper we present a telemedical EEG analysis environment based on virtual reality technologies. The same EEG signal/recording 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 secondary presentation modality. The environment is based on a VRML head model animated with Java applets, and allows the use of standard web browser. c ©1999 Elsevier Science B.V. All rights reserved.
