Visual-Speller-Stimulus
Stimulus presentation for a visual speller, created using the libGDX framework.
So far only contains a proof of concept stimulus presentation in order to test performance.
Definition
Based on jadref's matrixSpeller.
Training:
Send event stimulus.training with value start
Show grid in gray 2000 ms
Sequence repeat 5 times:
Send event stimulus.sequence with value start
send event stimulus.targetSymbol with value of target
Show target symbol in green 2000 ms
Stimulus repeat 5 times for each column and row:
Show grid in gray 150 ms
Send event stimulus.rowFlash with value of flashed row
Send event stimulus.columnFlash with value of flashed column
Send event stimulus.tgtFlash with true if row/column contains target
Flash column/rows white 150 ms
Send event stimulus.sequence with value end
send event stimulus.training with value end
Feedback:
Send event stimulus.feedback with value start
Show grid in gray 2000 ms
Sequence repeat X times:
Send event stimulus.sequence with value start
Stimulus repeat 5 times for each column and row:
Show grid in gray 150 ms
Send event stimulus.rowFlash with value of flashed row
Send event stimulus.columnFlash with value of flashed column
Flash column/rows white 150 ms
Show grid grey 950 ms (waiting for the classifier)
Send event stimulus.sequence with value end
Get new classifier events.
Correlate classifier events with flash sequence to determine prediction symbol.
Send event stimulus.prediction with value of prediction symbol.
Show prediction symbol in red 5000 ms
send event stimulus.feed with value end
