<u><b><big>Scenario Overview</big></b></u>
This scenario is used as a first step to
collect some training data. The data
will later be used to train a spatial
filter and a classifier for online use of
the Tactile BCI System.
Spelling automatically starts delayed to the start
of scenario execution.
First the target Tactilo will vibrate and flash in the
<i>Speller Visualization</i>(Copy Spelling Only).
After that you have to Focus on your chosen
(or the predetermined Target), while all Tactilos
will vibrate (flash) several times.
This will be repeated for a defined number of trials.
After each Trial, the detected Tactilo will be presented
in the <i>Speller Visualization</i>
