- The person in charge was Dr. Jacques Vidal. His lab
- was called the brain-computer interface lab. Here is a
- relevant publication (refer format):
-
- %A Jacques J. Vidal
- %T Real-Time Detection of Brain Events in EEG
- %J Proceedings of the IEEE
- %V 65
- %N 5
- %D May, 1977
- %P 633-641

- It is important to emphasize that this work did not
- detect "thoughts" at all, and was never claiming that
- it did. Rather it detected "event-related potentials",
- the events being a stimulus--a light flashing, and
- based on which direction you were LOOKING (not thinking
- about looking, but actually looking), the project
- performed pattern recognition techniques to determine
- the gaze direction from the evoked EEG signal.
