Optimization of Brain Computer Interface systems by means of XML and BF++ Toys

The optimization of Brain Computer Interface systems is of great importance for the purpose of making them more usable and adjustable according to the needs of the end users. However, when evaluating their performances, it is evident the lack of a standard metric and of a common way to describe or represent the behavior, characteristics and data relative to the functional modules that compose them. The need of sharing data virtually everywhere and of making them usable by every researcher has inspired the work described in this paper: a set of tools, the BF++ Toys, which simulate and optimize the behavior of BCI systems, were implemented. They made wide use of the XML technology for describing and documenting all the main entities involved in BCI. Finally it will be shown how BF++ Toys and XML represent a versatile and reliable mean for the purpose of optimizing BCI systems. K eywords: BCI; BF++ Toys; XML; Optimization; File Formats.
