In the first part of the paper is presented a BCI-CAD interface that can be used for geometric modeling applications. The proposed solution for BCI-CAD integration tries to preserve all advantages of using the existing legacy CAD software and add on top of it a BCI interface as an alternative to the existing classical WIMP paradigm. In the second part, we present a evaluation study of the BCI-CAD system by trials with subjects carrying out a standard CAD modeling session. The results are discussed in the last part of the paper.I.3.6 [Information Systems]User Interfaces
