D2.1 Requirements and Specification - CORBYS

D2.1 Requirements and Specification
BCI requires a machine free training stage before users can work the technology. The
training process modifies some internal parameters that successively the decoding process
uses. This procedure must be observed for each cognitive-related task is planned to be used.
A training phase is also needed for the artefacts removal processing (Training artefacts).
The possible values of the execution mode input are
� Training motion *
� Training feedback
� Training attention
� Training artefacts
� Decoding motion
� Decoding feedback
� Decoding attention
� Decoding motion & feedback
� Decoding motion & attention
� Decoding feedback & attention
� Decoding motion & feedback & attention
� Stop
The independence of the cognitive-related tasks allows their simultaneous execution in the
decoding process (i.e. Decoding motion & feedback, Decoding attention & feedback, etc.).
A stop input value has been also added to allow the interruption of the running processes.
*Motion, feedback and attention are the abbreviations for intention of legs motion, feedback
error-related potential and attention states respectively.
