确定脑机接口（BCI）是否可以用作即插即用输入设备来操作商业辅助技术，并量化这种操作对性能的影响。使用我们实验室设计的硬件设备，参与者（11名肌萎缩侧索硬化症患者，22名对照）被要求使用BCI操作两个设备。结果与相同用户的传统BCI操作进行了比较。使用准确性和BCI实用程序（吞吐量指标）评估性能。使用线性混合模型开发了性能差异的95%置信区间。观察到的准确度和通量差异很小，没有统计学意义。置信界限表明，如果使用BCI控制辅助技术设备会对性能产生影响，则该影响可以通过辅助技术设备本身的优势轻松克服。辅助技术设备的BCI控制是可能的，并且性能差异似乎非常小。鼓励BCI设计人员将标准输出纳入其设计中，以使未来的用户能够与熟悉的辅助技术设备进行交互。
To determine if a brain-computer interface (BCI) could be used as a plug-and-play input device to operate commercial assistive technology, and to quantify the performance impact of such operation. Using a hardware device designed in our lab, participants (11 with amyotrophic lateral sclerosis, 22 controls) were asked to operate two devices using a BCI. Results were compared to traditional BCI operation by the same users. Performance was assessed using both accuracy and BCI Utility, a throughput metric. 95% confidence bounds on performance differences were developed using a linear mixed model. The observed differences in accuracy and throughput were small and not statistically significant. The confidence bounds indicate that if there is a performance impact of using a BCI to control an assistive technology device, the impact could easily be overcome by the benefits of the assistive technology device itself. BCI control of assistive technology devices is possible, and the performance difference appears to be very small. BCI designers are encouraged to incorporate standard outputs into their design, to enable future users to interface with familiar assistive technology devices.
