Multi Modal Viewer for Telemedical Applications

An advantageous aspect of telemedicine is that it can create virtual environments for collaboration between patient, physicians, and medical staft. In this paper we present a multimodal interactive environment for EEG/MEG data presentation based on a virtual reality user interface (VRUI). In addition, to visualization, the VRUI uses sonification. The proposed approach requires only a standard Web browser. Multi modal viewer presents 3D EEG topographic maps using VRML head model, animated with Java applets. Since animation on the 3D models gives an insight into spatio-temporal patterns of activity. We have applied sonification to emphasize the -temporal dimension of selected visualized scores.
