在这项研究中，我们研究了脑-机接口（BCI）的基础上，脑电响应的振动触觉刺激的腰部。基于触觉刺激的P300脑机接口的优点是不会对视觉或听觉系统造成负担，并且可能不被其他人注意到。触觉BCI可能特别适用于视力或眼球运动受损的患者。在实验1中，我们研究了它的可行性和等距触觉器的数量的影响。尽管大量的触觉器预期会增强P300幅度，因为目标将不那么频繁，但它也可能对P300产生负面影响，因为当触觉器密度增加时，将难以识别目标。参与者被要求注意目标触觉器的振动，嵌入在一系列干扰物中。触觉器的数量是两个、四个或六个。我们证明了触觉P300 BCI的可行性。我们没有发现不同数量的触觉器之间的SWLDA分类性能的差异。在第二组实验中，我们通过缩短触觉器的开启和/或关闭时间来减少刺激起始时间（SOA）。在我们的实验中测得的最佳性能的SOA原来是接近传统的SOA的视觉P300脑机接口。
In this study, we investigated a Brain-Computer Interface (BCI) based on EEG responses to vibro-tactile stimuli around the waist. P300 BCIs based on tactile stimuli have the advantage of not taxing the visual or auditory system and of being potentially unnoticeable to other people. A tactile BCI could be especially suitable for patients whose vision or eye movements are impaired. In Experiment 1, we investigated its feasibility and the effect of the number of equally spaced tactors. Whereas a large number of tactors is expected to enhance the P300 amplitude since the target will be less frequent, it could also negatively affect the P300 since it will be difficult to identify the target when tactor density increases. Participants were asked to attend to the vibrations of a target tactor, embedded within a stream of distracters. The number of tactors was two, four or six. We demonstrated the feasibility of a tactile P300 BCI. We did not find a difference in SWLDA classification performance between the different numbers of tactors. In a second set of experiments we reduced the stimulus onset asynchrony (SOA) by shortening the on- and/or off-time of the tactors. The SOA for an optimum performance as measured in our experiments turned out to be close to conventional SOAs of visual P300 BCIs.
