The two signals are:

1. Signal generated with eyes open while observing someone else perform the action but the subject is not performing the action.

2. Signal generated when there is no vision of action but on indication to imagine (maybe a sound), the subject is imagining the action.

Are these two signals same of different? I am searching for an answer because I need EEG signal for testing an algorithm. But I have signal belonging to 2 while my requirement is for 1.
