基于稳态视觉诱发电位（SSVEP）的脑-机接口（BCI）系统比使用其他脑信号的BCI系统提供更高的信息吞吐量并且需要更短的训练。为了引出SSVEP，必须向用户呈现重复视觉刺激（RVS）。RVS可以通过交替的图形图案或能够发射调制光的外部光源在计算机屏幕上呈现。RVS的属性（例如，频率、颜色）取决于渲染设备并影响SSVEP特征。 这会影响BCI信息吞吐量以及用户安全和舒适程度。关于基于SSVEP的BCI的文献通常不提供选择所使用的渲染设备或RVS属性的原因。在本文中，我们回顾了文献SSVEP为基础的脑机接口和全面报告不同的RVS的选择方面的渲染设备，属性，以及它们对脑机接口的性能，用户的安全性和舒适性的潜在影响。
Brain-computer interface (BCI) systems based on the steady-state visual evoked potential (SSVEP) provide higher information throughput and require shorter training than BCI systems using other brain signals. To elicit an SSVEP, a repetitive visual stimulus (RVS) has to be presented to the user. The RVS can be rendered on a computer screen by alternating graphical patterns, or with external light sources able to emit modulated light. The properties of an RVS (e.g., frequency, color) depend on the rendering device and influence the SSVEP characteristics. This affects the BCI information throughput and the levels of user safety and comfort. Literature on SSVEP-based BCIs does not generally provide reasons for the selection of the used rendering devices or RVS properties. In this paper, we review the literature on SSVEP-based BCIs and comprehensively report on the different RVS choices in terms of rendering devices, properties, and their potential influence on BCI performance, user safety and comfort.
