本研究的目的是测试新的听觉脑机接口（BCI）通信应用程序的可用性。我们引入了一种基于单词的直观听觉拼写范例 WIN-speller。在 WIN 拼写器中，字母按单词分组，例如单词 KLANG 代表字母 A、G、K、L 和 N。因此，感知代码和将其翻译为它所代表的刺激之间的解码步骤变得多余。我们在复制拼写模式下测试了 11 名健康志愿者和 4 名有运动障碍的最终用户。在健康样本中，拼写成功，平均准确率为 84%。其中 3 位最终用户的平均通信准确度达到 80% 或更高，而 1 位用户则无法可靠地进行通信。尽管需要进一步评估，WIN-speller 代表了最终用户基于 BCI 通信的潜在替代方案。
The objective of this study was to test the usability of a new auditory Brain-Computer Interface (BCI) application for communication. We introduce a word based, intuitive auditory spelling paradigm the WIN-speller. In the WIN-speller letters are grouped by words, such as the word KLANG representing the letters A, G, K, L, and N. Thereby, the decoding step between perceiving a code and translating it to the stimuli it represents becomes superfluous. We tested 11 healthy volunteers and four end-users with motor impairment in the copy spelling mode. Spelling was successful with an average accuracy of 84% in the healthy sample. Three of the end-users communicated with average accuracies of 80% or higher while one user was not able to communicate reliably. Even though further evaluation is required, the WIN-speller represents a potential alternative for BCI based communication in end-users.
