Functional Evaluation

Real-Time Direct Brain Interface System

Two graphs showing ERP averages.  The first was created using triggered averaging, the second using triggerless averaging with 4 iterations.  The amplitude appears identical on the two graphs.  The ERPs are very similar, although the one created using triggerless averaging is somewhat more noisy.

Feedback Training

Drawing:  A row of lightbulbs appears across the top with a solid line two thirds of the way from the bottom.  A small figure stands at the bottom in the center.  The words 'Attempt #6' extend upward from the figure.  Four of the five bulbs to the left of the figure are lit while the remaining one has an X through it.  An F appears above the solid line between two of the lit bulbs.  Writing on the left indicates that Jumps are 80%, Faults are 20%, there was one fault and the score is 60.

Direct Brain Interface Performance Testing

Direct brain interface used to play computer game (with timing requirements)

Drawing.  A defensive LASAR sits in the middle of 6 buildings, one of which is destroyed.  A missle is pointed at the buildings from above.  Text along the bottom states that 4 enemy have been destroyed and 5 buildings remain.

Direct brain interface used to operate simple scanning communication system (requires timing and concentration)

Text box.  The question 'Which of the following terms describes an intellectual person?' appears at the top.  Under it are four answers:  Couch potato, String bean, Egg-head, Cool cumcumber.  Egg-head is highlighted.
