mindBEAGLE uses Brain-Computer Interface (BCI) technology for quick and easy assessment of DOC and LIS patients and even provides basic communication with some of them. It is used to determine whether patients can understand and follow basic task instructions, even though they are diagnosed as people in a vegetative state (VS, also called UWS or Unresponsive Wakefulness Syndrome), minimally conscious state (MCS) or (completely) locked-in state (LIS/CLIS).
