Pervasive Direct Brain Interfaces

Several areas of study could provide significant breakthroughs in making direct brain interface systems work. First, improving techniques for obtaining clear and artifact-free brain signals are difficult but critical to making DBIs feasible. Invasive techniques, such as implanted electrodes, could provide better control through clearer, more distinct signal acquisition. We can improve noninvasive techniques, such as scalp electrodes and functional near-infrared (fNIR) imaging, by reducing noise and incorporating more sophisticated filters. In addition, we need much more research on under standing how best to use DBIs in real-world applications
