Different control strategies exist for use in a brain-computer interface (BCI). Although process control is the prevailing control strategy for most sensorimotor rhythm based BCIs, the goal selection strategy more closely resembles normal motor control and may be more accurate, faster to use, and easier to learn. We describe here a sensorimotor rhythm based goal selection BCI and a pilot study to compare it with process control strategy in terms of accuracy and speed of use. In both trained and naïve subjects studied, goal selection outperformed process control.
在脑机接口（BCI）中存在不同的控制策略。尽管过程控制是大多数基于感觉运动节律的脑机接口的主要控制策略，但目标选择策略更类似于正常的运动控制，可能更准确、使用更快且更容易学习。我们在此描述一种基于感觉运动节律的目标选择脑机接口以及一项初步研究，以在准确性和使用速度方面将其与过程控制策略进行比较。在所研究的训练有素和未经过训练的受试者中，目标选择均优于过程控制。
