متن کاملA Fast, Robust, Automatic Blink Detector
Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
متن کاملDon't Blink! Evaluating Training Paradigms for Overcoming the Attentional Blink
A lot of people show a decline in performance when they have to report a second target stimulus in a stream of distractor stimuli. Curiously, this decline only happens when the second target appears approximately 200-500ms after the first target. Recently, Choi, Chang, Shibata, Sasaki, and Watanabe (2012) have shown that a short, one-hour training can eliminate this “attentional blink”. Up to n...
متن کاملUnmasking the attentional blink.
When asked to identify 2 visual targets (T1 and T2 for the 1st and 2nd targets, respectively) embedded in a sequence of distractors, observers will often fail to identify T2 when it appears within 200-500 ms of T1--an effect called the attentional blink. Recent work shows that attention does not blink when the task is to encode a sequence of consecutive targets, suggesting that distractor inter...
متن کاملBlink-related eye movements.
Eye movements that accompany a blink have been measured in human subjects by the use of a visual-persistence method. With straight-ahead binocular viewing, each eye typically rotates nasalward and downward 1-2 deg during the closing phase of a blink. These eye movements are more rapid than the lid movements as recorded by high-speed photography. In fact, the eyes have already completed their in...
