在利用过程控制策略的脑机接口（BCI）中，来自皮层的信号用于控制通常由大脑其他部分处理的精细运动细节。在利用目标选择策略的BCI中，来自皮层的信号用于确定用户的总体最终目标，并且BCI控制精细运动细节。基于目标选择的BCI可能比基于过程控制的BCI更容易和更自然。虽然理论上目标选择可能优于过程控制，但正如我们在这里报告的那样，这两者从未被直接比较过。八名年轻健康的人类受试者参与了本研究，三名受过BCI使用训练，五名未经BCI使用训练。头皮记录的脑电图（EEG）被用来控制计算机光标在五个不同的范式。这些范例在其基础信号处理方面是相似的，并且使用相同的控制信号。然而，三个是基于目标选择，两个是基于过程控制。对于受过训练的和幼稚的人群，目标选择每次运行的命中率更高，更快，更准确（7/8的受试者），并且比过程控制具有更高的信息传递率。目标选择优于过程控制在本调查研究的每一个措施。
In a brain-computer interface (BCI) utilizing a process control strategy, the signal from the cortex is used to control the fine motor details normally handled by other parts of the brain. In a BCI utilizing a goal selection strategy, the signal from the cortex is used to determine the overall end goal of the user, and the BCI controls the fine motor details. A BCI based on goal selection may be an easier and more natural system than one based on process control. Although goal selection in theory may surpass process control the two have never been directly compared, as we are reporting here. Eight young healthy human subjects participated in the present study, three trained and five naïve in BCI usage. Scalp recorded electroencephalograms (EEG) were used to control a computer cursor during five different paradigms. The paradigms were similar in their underlying signal processing and used the same control signal. However, three were based on goal selection, and two on process control. For both the trained and naïve populations, goal selection had more hits per run, was faster, more accurate (for 7/8 subjects), and had a higher information transfer rate than process control. Goal selection outperformed process control in every measure studied in the present investigation.
