我们的日常工作变得越来越复杂，对认知的要求也越来越高。我们在一天中所关注的会影响我们的大脑如何有效地为行动做好准备，以及我们在任务中付出了多少努力。为了解决这个问题，我们提出了AttentivU -一个使用可穿戴脑电图（EEG）来实时测量人的注意力的系统。当用户的注意力水平较低时，系统提供实时、微妙的触觉或音频反馈，以促使用户再次变得专注。我们测试了该系统的第一个版本，该系统在实验室和教室环境中对48名成年人使用EEG头带进行了多次测试。结果表明，生物反馈将参与者的注意力重新引导到手头的任务上，并提高了他们在理解测试中的表现。接下来，我们在实验室环境中对6名成年人进行了眼镜形式的测试，因为从长远来看，眼镜的形状因素可能更容易接受。最后，我们讨论了目前正在开发的AttentivU的第三个改进版本，该版本将眼镜形状因子的定制解决方案与内置的眼电图（EOG）和EEG电极以及听觉反馈相结合。
Our everyday work is becoming increasingly complex and cognitively demanding. What we pay attention to during our day influences how effectively our brain prepares itself for action, and how much effort we apply to a task. To address this issue we present AttentivU -a system that uses wearable electroencephalography (EEG) to measure the attention of a person in realtime. When the user's attention level is low, the system provides real-time, subtle, haptic or audio feedback to nudge the person to become attentive again. We tested a first version of the system, which uses an EEG headband on 48 adults over several sessions in both a lab and classroom setting. The results show that the biofeedback redirects the attention of the participants to the task at hand and improves their performance on comprehension tests. We next tested the same approach in the form of glasses on 6 adults in a lab setting, as the glasses form factor may be more acceptable in the long run. We conclude with a discussion of an improved third version of AttentivU, currently under development, which combines a custom-made solution of the glasses form-factor with built-in electrooculography (EOG) and EEG electrodes as well as auditory feedback.
