Here are some screenshots of the system. Yellow represents your Focus level, blue shows your Neureka! level, while gray indicates when you tighten up your facial muscles and disrupt the signal. Two green lines result from a blink. This is a Focus Training screen, where it controls the size of a DVD...too low and it stops.
This is the Socialize ACE DVD Training Screen. Neureka! changes the size of the picture while Focus Controls the Brightness. If either goes too low it stops.
