Computer control using human intracortical local field potentials.
We describe the use of human cortical control signals to operate two assistive technology tools--a virtual keyboard speller and a computer-simulated digit. The cortical signals used for control are local field potentials recorded through an implanted neurotrophic electrode. In this system, the patients' cortical signals are transmitted wirelessly to a receiver and translated by computer software into either a computer cursor movement (for the virtual keyboard) or flexion of a cyber digit on a virtual hand. This report focuses on the progress of two subjects toward effective use of their "virtual" neuro-prosthetic devices to meet their assistive technology needs.
