Hi

I'm working with the CSP BCI scenario and I was wondering if it was possible to detect the strength of the imagined hand movement using EEG signals and Openvibe ?

currently the scenario only classifies the imagined hand movements right or left .

Cheers,
Kiarash

Hi,

the classifier processor box returns additional outputs such as class probability that can be used as a strength guess. See the box manuals for trainer/processor boxes.

In theory, if we knew the strength of each training trial, we could build a regression model predicting this strength, but unfortunately its hard to extract such info from the user correctly in the first place.

Cheers,
Jussi
