This paper presents a novel brain-computer-interface (BCI) system that could potentially be used for enhancing the attention ability of subjects with attention deficit hyperactivity disorder (ADHD). It employs the steady state visual evoked potential (SSVEP) paradigm. The developed system consists of a 3D classroom environment with active 3D distractions and 2D games executed on the blackboard. The system is concealed as a game (with stages of varying difficulty) with an underlying story to motivate the subjects. It was tested on eleven healthy subjects and the results undeniably establish that by moving to a higher stage in the game where the 2D environment is changed to 3D along with the added 3D distractions, the difficulty level in keeping attention on the main task increases for the subjects. Results also show a mean accuracy of 92.26 ± 7.97% and a mean average selection time of 3.07 ± 1.09 seconds.
本文提出了一种新型脑机接口（BCI）系统，该系统有可能用于提高注意力缺陷多动障碍（ADHD）患者的注意力。它采用稳态视觉诱发电位（SSVEP）范式。所开发的系统由一个带有动态3D干扰的3D教室环境和在黑板上执行的2D游戏组成。该系统被隐藏成一款带有潜在故事以激励受试者的游戏（具有不同难度级别）。它在11名健康受试者身上进行了测试，结果无可争议地表明，当受试者进入游戏中更高的级别，即2D环境变为3D并伴有额外的3D干扰时，他们在专注于主要任务方面的难度增加。结果还显示平均准确率为92.26±7.97%，平均选择时间为3.07±1.09秒。
