RADAR: A novel fast-screening method for reading difficulties with special focus on dyslexia

We introduce a novel, fast, objective, non-invasive method, named Rapid Assessment of Difficulties and Abnormalities in Reading (RADAR) that screens for features associated with the aberrant visual scanning of reading text, seen in dyslexia. Eye tracking parameter measurements that are stable under retest and have high discriminative power, as indicated by their ROC (Receiver Operating Characteristic) curves, were obtained during silent text reading. Analysis of eye movement parameters obtained with RADAR during reading will likely be useful for implementing individualized treatment strategies and for monitoring objectively the success of chosen interventions.<br>

我们提出了一种新颖、快速、客观且非侵入式的方法——阅读困难与异常快速评估法（Rapid Assessment of Difficulties and Abnormalities in Reading，缩写RADAR），该方法可用于筛查与阅读障碍患者阅读文本时出现的异常视觉扫描相关的特征。在默读文本的过程中，我们获取了重测稳定性良好且判别能力优异的眼动追踪参数测量值，此类参数的ROC（受试者工作特征，Receiver Operating Characteristic）曲线可佐证其优良的判别性能。基于RADAR在阅读过程中获取的眼动追踪参数开展分析，或可用于制定个体化治疗策略，以及客观监测所选干预措施的实施效果。
