面向最终用户的BCI拼写器使用了许多不同的技术,但许多技术都要求将屏幕不同区域的刺激集中起来以获得最佳性能。然而,空间独立性对于患有闭锁综合征的患者具有相当大的价值,这大大削弱了他们的自主运动能力。为此,我们设计了一个10段的字母子集库,这些字母子集组合创建字母表中的字母。因此,片段可以集中呈现,允许字母并行提示,同时保持rsvp风格拼写器的空间独立性。68%的分段分类准确率产生了一个相当快的拼写器,有几种方法可以最大限度地提高准确性和信息传输速率。
BCI Spellers for end-users utilize numerous different techniques, but many require that stimuli in different areas of the screen be foveated for best performance. Spatial independence, however, is of considerable value for patients suffering from locked-in syndrome, which significantly attenuates their capacity for voluntary movements. To this end, we have designed a 10-segment library of letter subsets, which combinatorially create the letters of the alphabet. Segments can thus be centrally presented, allowing letters to be cued in parallel while maintaining the spatial independence of RSVP-style spellers. A 68% segmentclassification accuracy yields a reasonably rapid speller, with several avenues for maximizing accuracy and information transfer rate.
