Control of a wheelchair simulator in a three-dimensional environment using eye blink detection through non-invasive brain-computer interface

Brain-Computer Interface (BCI) is a computational system capable of establishing communication between neurophysiological activity and a computer. This paper presents the study and the development of the prototype of a wheelchair simulator in a three-dimensional environment, controlled by non-invasive BCI. To this end, we used a low-cost electroencephalogram, the NeuroSky Mindwave, as the device for signals acquisition. For the development, the game engine Unity3d was used. The prototype can detect the blink of eyes, and, therefore, this feature is used as a command to the simulator. The simulator will be used to train people with special needs, in a way that when they use the wheelchair, it will be easier to control the equipment, preventing accidents.
