Brain–computer interfaces (BCIs) provide a novel form of human–computer interaction. The purpose of these systems is to aid disabled people by affording them the possibility of communication and environment control. In this study, we present experiments using a P300 based BCI in a fully immersive virtual environment (IVE). P300 BCIs depend on presenting several stimuli to the user. We propose two ways of embedding the stimuli in the virtual environment: one that uses 3D objects as targets, and a second that uses a virtual overlay. Both ways have been shown to work effectively with no significant difference in selection accuracy. The results suggest that P300 BCIs can be used successfully in a 3D environment, and this suggests some novel ways of using BCIs in real world environments.

In this era of co-evolution of humans and computers, we are witnessing a lot of fear that humanity will lose control and autonomy. This is a possibility. Another is the development of symbiotic systems among men and machines. To accomplish this goal, it is necessary to research ways to apply some key concepts that have a catalytic effect over such ideas. In the discussion of this hypothesis through the case study of the spectacle MindFluctuations— an experimental artwork exploring neural connections—we are looking for ways to develop them from conception to realization. The discussion also establishes a process of reflection on the design, development and production of this dance spectacle. This artwork uses a customized Java application, NumericVariations, to explore the quoted neural connections for spectacles, performances and site-specific installations. Its approach was made possible by recent neuroscience research and the development of a Brain Computer Interface (BCI) integrated with a virtual reality framework, which enable an experimental interactive virtual reality artwork to emerge. A neural helmet connected to the computer and entwined with mathematical procedures enabled a symbiosis of humans with computers.

AbstractObjectivesThis presents a case for fear and stress stimuli and afterward EEG data analysis.MethodsThe stress factor had been evoked by a computer horror game correlated with virtual reality (VR) and brain-computer interface (BCI) from OpenBCI, applied for the purpose of brain waves changes observation.ResultsResults obtained during the initial study were promising and provide conclusions for further research in this field carried out on an expanded group of involved participants.ConclusionsThe study provided very promising and interesting results. Further investigation with larger amount of participants will be carried out.

The aim of the present study was to demonstrate for the first time that brain waves can be used by a tetraplegic to control movements of his wheelchair in virtual reality (VR). In this case study, the spinal cord injured (SCI) subject was able to generate bursts of beta oscillations in the electroencephalogram (EEG) by imagination of movements of his paralyzed feet. These beta oscillations were used for a self-paced (asynchronous) brain-computer interface (BCI) control based on a single bipolar EEG recording. The subject was placed inside a virtual street populated with avatars. The task was to “go” from avatar to avatar towards the end of the street, but to stop at each avatar and talk to them. In average, the participant was able to successfully perform this asynchronous experiment with a performance of 90%, single runs up to 100%.

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.
