The Functional Near-Infrared Imaging Device (fNIR) is a technology that was developed at the University of Pennsylvania, but is currently being used by the Drexel University biomedical department. The device shines infrared light into the user's forehead, and records the amount of light that gets transmitted back. The change in the amount of light can be used to deduce information about the amount of oxygen in the blood. When the user concentrates, their frontal lobe needs more oxygen and this change can be detected by the device.

Thanks to Drexel University's School of Biomedical Engineering, we are able to incorporate this device into our gaming environment. All of this would not have been possible without our Biomed advisor, Hasan Ayaz, as well as the support and enthusiasm from the Biomed Director, Dr. Banu Onaral.
