I'm glad you got it working !
My need now is, to analyze the accuracy with which OpenVibe recognized the signal patterns based on the config file. I wish to do this by having OpenVibe type a specific letter when the blue bar in the Graz visualisation reaches a certain threshold (either on the left or right side of the coordinate plane). Is this possible?
The second output of the classifier processor box
is a Streamed Matrix that contains a value, whose sign gives you the side and absolute value gives you the amplitude of the blue bar. This value is the distance to hyperplan computed by the LDA classifier
. As stated in the box documentation :
Unexepected behavior may (will) occur when changing the classifier.
We don't provide in openvibe a way to emulate the keyboard. However it is possible to send stimulation codes or analog values in a VRPN server, that a third party application could read and "type" a specific letter depending on the VRPN input. Anyway, I'm afraid you will have to implement something
hope this helps,
