摘　　要：运动想象(MI)是驱动脑机接口(BCI)的一种重要范式,但MI心理活动不易控制或习得,MI-BCI的性能严重依赖被试MI的表现。因此MI心理活动的正确执行以及能力的评估和提高对MI-BCI系统性能的提升及应用具有重要的甚至关键性的作用。然而,在MI-BCI的研发中,已有研究主要聚焦于解码MI的算法,对MI心理活动的这三个方面没有足够的重视。本文针对MI-BCI的这些问题进行详细论述,指出被试易把动觉运动想象执行为视觉运动想象;未来需要研发客观的、定量可视化的MI能力评估方法,并且需要研发有效的、训练时间短的MI能力提高方法,也需要在一定程度上解决个体之间和内部MI的差异性、共性和MI-BCI盲问题。Motor imagery(MI)is an important paradigm of driving brain computer interface(BCI).However,MI is not easy to control or acquire,and the performance of MI-BCI depends heavily on the performance of the subjects’MI.Therefore,the correct execution of MI mental activities,ability evaluation and improvement methods play important and even critical roles in the improvement and application of MI-BCI system’s performance.However,in the research and development of MI-BCI,the existing researches mainly focus on the decoding algorithm of MI,but do not pay enough attention to the above three aspects of MI mental activities.In this paper,these problems of MI-BCI are discussed in detail,and it is pointed out that the subjects tend to use visual motor imagery as kinesthetic motor imagery.In the future,we need to develop some objective,quantitatively visualized MI ability evaluation methods,and develop some effective and less time-consumption training methods to improve MI ability.It is also necessary to solve the differences a nd commonness of MI problems between and within individuals and MI-BCI illiteracy to a certain extent.
