脑机接口(BCI)研究的目标是为瘫痪和心律失常患者开发快速可靠的通信方式。我们评估了参加 BrainGate 神经接口系统试点临床试验 (IDE) 的不完全锁定综合征患者使用神经点击控制进行交流的能力。开发了通用界面,以提供对计算机光标与两个屏幕虚拟键盘之一的控制。在平衡的复制拼写任务中,将新颖的 BrainGate 径向键盘与标准 QWERTY 键盘进行了比较。径向键盘显着提高了打字准确性和速度 - 使打字速度超过每分钟 10 个正确字符。参与者使用该界面通过文本到语音转换与研究人员进行面对面交流,并使用互联网聊天应用程序进行远程交流。这项研究展示了患有不完全锁定综合症的个体首次使用皮质内脑机接口进行神经点击式通信。
A goal of Brain-Computer Interface (BCI) research is to develop fast and reliable means of communication for individuals with paralysis and anarthria. We evaluated the ability of an individual with incomplete locked-in syndrome enrolled in the BrainGate Neural Interface System pilot clinical trial (IDE) to communicate using neural point-and-click control. A general-purpose interface was developed to provide control of a computer cursor in tandem with one of two on-screen virtual keyboards. The novel BrainGate Radial Keyboard was compared to a standard QWERTY keyboard in a balanced copy-spelling task. The Radial Keyboard yielded a significant improvement in typing accuracy and speed – enabling typing rates over 10 correct characters per minute. The participant used this interface to communicate face-to-face with research staff by using text-to-speech conversion, and remotely using an internet chat application. This study demonstrates the first use of an intracortical BCI for neural point-and-click communication by an individual with incomplete locked-in syndrome.
