mentalCommandBrainMap

This method returns the brain map of a profile. The brain map is a graphic representation of the mental command training of the user. It indicates which actions are most distinct from each other and from the neutral state as measured by how often the training data is misclassified. The better training you do, the more separated the coordinates will be.

Check out the usage in our BCI app.

Parameters

Name	Type	Required	Description
cortexToken	string	yes	A token returned by authorize.
profile	string	no	A profile name.

The result is an array of objects. Each object is represents a trained actions and contains these fields:

Name	Type	Description
action	string	The action name.
coordinates	array of 2 numbers	The (x, y) coordinates of this action in the brain map. x is in range [-1.0, 1.0] and y is in range [0.0, 1.0].
