当用户与诸如计算机之类的界面交互时，其对特定生物信号的影响可以反映对界面的情感反应，从而提供了评估可用性的手段。为了开发一种能够根据用户的S情绪调整其可用性的界面，这里我们解码了在与用户不友好的界面交互时发生的脑电活动。受试者执行到达目标的任务，S，而不规则的变换被应用于光标运动以诱导挫折感。结果表明，来自额叶电极(AF3-AF4)的差异信号足以区分转换过程中的大脑活动(受挫)和正常光标运动(非受挫)。在相同的任务中，功能性磁共振成像显示S在额中回、眶前回和顶下皮质显著激活，这些区域被发现与负面情绪有关。总而言之，这些结果表明，接口的可用性可以通过脑电信号来衡量，这可能有助于开发自适应接口，从而增加其直观性。
When a user interacts with an interface such as a computer, its effects on specific biosignals may reflect emotional responses to the interface, providing a means to evaluate usability . Towards the develop ment of an interface that can adapt its usability based on the user ’ s emotions , here we decode d electroencephalography (EEG) activity occurring during interaction with a user- un friendly interface. Participants performed target-reaching task s while irregular transformations were applied to cursor motion to induce frustration. O ur results showed that differential signals from the frontal electrodes (AF3-AF4) were sufficient to classify between brain activities during transformed (frustrated) and normal cursor motion (non-frustrated) . F unctional magnetic resonance imaging during the same tasks showed significant activation s in the middle frontal gyrus, orbitofrontal gyrus, and inferior parietal cortex , areas found to be related to negative emotions . Altogether, these results suggest that the usability of an interface can be measured from EEG signals, which could aid in the development of adaptive interfaces that increase its intuitiveness.
