SBCI: 3D Simulator with Brain-Computer Interface and Virtual Reality

The use of Brain-Computer Interfaces (BCI) grows after each passing day. The technology is mainly used for rehabilitation and social inclusion platform in favor of disabled individuals. Using BCI as a method of treatment, one can observe considerable improvements in the functionality of the affected limb which goes as far as enabling once thought impossible tasks. This article consists of a study about BCI and the validation of the obtained knowledge through the development of a 3D simulation system controlled by the BCI, with the main objective of rehabilitating people with upper body limitations. The methodology consists in capturing brain waves and cognitive information with a neural headset, which sends the data to an application to analyze and convert said data into various actions the 3D simulator can execute. Then, the user undergoes a series of neural tests, where he can move two virtual arms with the power of thought interacting with the simulated environment. To increase the realism and immersion of the environment, virtual reality goggles were integrated into the simulator. The results obtained were mostly satisfactory. It can be concluded that the BCI can help in the rehabilitation of people with upper body limitations in a more dynamic way, with the added possibility of reutilizing the developed BCI in other types of analysis or rehabilitation.
