2.8  Sensor Contact Quality Display 

Accurate  detection  results  depend  on  good  sensor  contact  and  signal  quality.  This  display  is  a 
visual  representation  of  the  current  contact  quality  of  the  individual  EPOC  Neuroheadset  sensors. 
The  display  is  a  smaller  copy  of  the  contact  quality  visualization  found  on  the  Control  Panel’s 
Neuroheadset  Setup  tab.  Please  see  Section  3.0  for  more  information  about  fitting  the  EPOC 
Neuroheadset and achieving good signal quality.
