Foreword
The  International  Brain-Computer  Interface  (BCI)  Meeting  Series  occupies  a  unique  place  among  conferences for  BCI  research  by  bringing  together  researchers  and  stakeholders  from  diverse  disciplines.  Neurologists, computer  scientists,  rehabilitation  engineers,  physicians,  sensor  engineers,  psychologists,  speech-language pathologists,  ethicists,  and  actual  BCI  users  are  all  active  participants  in  the  BCI  Meeting  Series.  Further,  the inclusive, retreat-like atmosphere of the BCI Meeting Series provides extensive opportunities for interaction anddevelopment of collaborations.Growing interest expressed in discussions over the course of the BCI Meeting Series (1999, 2002, 2005, 2010, and  2013) led  to  the  establishment  of  the  BCI  Society  in  2015.  The  purpose  of  this  international  society (http://bcisociety.org/) is “to  foster  research  and  development  leading  to  technologies  that  enable  people  to interact with the world through brain signals.” To further this purpose, the BCI Society is organizing the SixthInternational  BCI  Meeting  from  May  30th–  June  3rd,  2016  at  the  Asilomar  Conference  Grounds  in  Pacific Grove,  California, United  States.  The  2016  BCI  meeting  has  a  theme  of BCI:  Past,  Present,  and  Future.  The diversity  of  BCI  researchers  represented  in the  planning  of  the  2016  BCI  meeting has  resulted  in  a  vibrant, exciting  Meeting  with  more  collaborative,  interactive  activities  and increased  involvement  from  the  many sectors that make up BCI research.The  papers  in  these  Proceedings  show  the diversity  of  applications  for  which  BCIs  are  developed  and  the diversity of data and analyses that contribute to progress in BCI research and the development of BCI products. Intended  applications  for  people  with  impairments  include  control  of  assistive  devices,  communication,  and therapeutic  effects  for  rehabilitation. Applications also extend  beyond  user  groups  of  people  with  physical impairments. BCIs are being used for basic research to discover more about brain function, neural feedback and brain-training, and a variety of entertainment applications, both for people with impairments and for the general population.Together, the 2016 BCI Meeting and its Proceedings represent the breadth of BCI research and help us to build on the  rich  past  of  BCI  research,  leverage  the  diverse  and  exciting  present,  and  create  a future  of  BCIs  as successful, beneficial tools both for people with disabilities and for the general populace. On  behalf  of  the  BCI Society  and  the  Program  Committee  for  the  2016  BCI  meeting, I  thank  you  for  your interest in the BCI Meeting and hope to see you at this and future installments in the BCI Meeting Series.
