AI Article Synopsis
- Researchers developed a system that uses human cortical signals to control two assistive tech devices: a virtual keyboard speller and a computer-simulated finger.
- The technology captures local field potentials via an implanted neurotrophic electrode and wirelessly transmits these signals to a computer that converts them into movements for a cursor or a cyber digit.
- The report highlights the progress of two patients as they learn to effectively use these neuro-prosthetic devices for their needs.
Article Abstract
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.
