A NOVEL APPROACH FOR CONFIGURING THE STIMULATOR OF A BCI FRAMEWORK USING XML
Abstract: In a working BCI
framework, all aspects must be considered as an integral part that contributes
to the successful operation of a BCI system. This also includes the development
of robust but flexible stimulator, especially the one that closely related to
the feedback of a BCI system. This paper describes a novel approach in
providing flexible visual stimulator using XML which has been applied for a BCI
(brain-computer interface) framework. Using XML file format for configuring the
visual stimulator of a BCI system, we can develop BCI applications which can
accommodate many experiment strategies in BCI research. The BCI framework and
its configuration platform is developed using C++ programming language which
incorporate Qt’s most powerful XML parser named QXmlStream. The implementation
and experiment shows that the XML configuration file can be well executed
within the proposed BCI framework. Beside its capability in presenting flexible
flickering frequencies and text formatting for SSVEP-based BCI, the
configuration platform also provides 3 shapes, 16 colors, and 5 distinct
feedback bars. It is not necessary to increase the number of shapes nor colors
since those parameters are less important for the BCI stimulator. The proposed
method can then be extended to enhance the usability of currently existed BCI
framework such as BF++ Toys and BCI 2000.
