我们描述了使用人类皮质控制信号来操作两种辅助技术工具-虚拟键盘拼写器和计算机模拟数字。用于控制的皮质信号是通过植入的神经营养电极记录的局部场电位。在这个系统中，病人的皮质信号被无线传输到一个接收器，并由计算机软件转换成计算机光标的移动（用于虚拟键盘）或虚拟手上数字的弯曲。本报告重点介绍了两项研究的进展，即如何有效地利用他们的“虚拟”神经假肢装置来满足他们的辅助技术需求。
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.
