Abstract


Brain-Computer  Interface  (BCI)  enables  users  to interact with  a  computer  only  through  their  brain  biological signals,  without  the  need to  use  muscles.  BCI  is  an emerging research  area  but  it  is  still  relatively  immature. However,  it  is important  to  reflect  on  the  different aspects of  the  Human-Computer  Interaction  (HCI)  area  related to BCIs,  considering that BCIs will be part of interactive systems in the near future. BCIs most attend not only to handicapped users, but also healthy ones, improving interaction for end-users. Virtual Reality (VR) is also an important part of interactive systems, and combined with BCI could greatly enhance user interactions, improving the user experience  by  using  brain  signals  as  input  with  immersive environments  as  output.  This  paper  addresses  only  noninvasive BCIs, since this kind of capture is the only one to not present risk to human health. As contributions of this work we highlight the survey of interactive systems based on BCIs focusing on HCI and VR applications, and a discussion on challenges and future of this subject matter.
