To measure fatigue severity in a manner that facilitates research in the experience of fatigue in a variety of medical and neurologic disorders (1). Content. Nine statements concerning respondent’s fatigue, e.g., how fatigue affects motivation, exercise, physical functioning, carrying. Many measures of the eye are known to be correlated with fatigue including coarse-grained measures like the rate of blinks as well as fine-grained measures .

Changing the cognitive demand had a greater impact on blink rate than presentation format. Mean blink rates for the low demand task were and blinks/min for the tablet and paper presentations, respectively, reducing significantly to and blinks/min, respectively, for the high demand task.
People did report more eye fatigue over the six hours, but the only measured difference was a slight increase in blink rate from about nine blinks per minute at the beginning to eleven blinks per minute at the end. You would think these results indicate that we would want to keep blink rates low. In this paper, we propose an experiment that assesses fusional response curve and eye-blink rate to measure visual fatigue induced by stereoscopic videos. A random dot stereogram was utilized to measure the reliable fusional limit and response curve acquired by determining the direction of Landolt C. The results were analyzed to discriminate the individual ability of 3D fusion and compared.

Issue 2, pp. - Issue published date: June Blink rate from the VEOG recording was used as an index of sustained attention.
• Blink rate decreased during the most difficult task indexing greater attentional load. • Blink rate rose after 4 min, regardless of task difficulty, indexing greater fatigue. • Eye blink is an ecological measure of dopaminergic component of attention and. 12 level of sleepiness from certain ocular measures, such as blink rate, blink duration, average distance between the.
Results. The mean and standard deviation of the blink rate and ocular symptoms assessed at different time points using different reading methods are shown in Tables 1 and and2.
mean baseline blink rate was ± /min. Significant fall in the blink rate was found after 15 min of reading either the book ( ± /min) or text on the electronic device ( ± /min. Results from both objective (Blinks per second) and subjective (Visual Fatigue Scale) measures suggested that reading on the LCD (Kindle Fire HD) triggers higher visual fatigue with respect to.
Detection of visual fatigue by analyzing the blink rate Abstract: One of the most common causes of traffic accidents is the driver's fatigue. So in this paper, a methodology for detection of eyestrain, in different lighting conditions, is presented by analyzing the blink rate.

Subsequently, in a real car-driving study published in , mental workload was captured with a number of physiological measures, including blink rate.
We tested possible fatigue indicators: 1. extracted from EEG spectrum; 2. based on blinking frequency, interval histogram and speed of blinks; 3. fractal properties of RR interval- series.
The first group of indicators is assumed to provide information about immediate fatigue level, whereas groups 2 and 3 are more suitable for determining the. Get this from a library. Blink rate as a measure of fatigue: a review. [J A Stern; D Boyer; David J Schroeder; United States.
Office of Aviation Medicine.; Civil Aeromedical Institute.]. Cognitive performance is defined as the ability to utilize knowledge, attention, memory, and working memory. In this study, we briefly discuss various markers that have been proposed to predict cognitive performance.
Next, we develop a novel approach to characterize cognitive performance by analyzing eye-blink rate variability dynamics. Our findings are based on a sample of 24 subjects.
Fatigue crack growth rate data are not always geometry-independent in the strict sense since thickness effects sometimes occur. However, data on the influence of thickness on fatigue crack growth rate are mixed. Fatigue crack growth rates over a wide range of Δ K have been reported to either increase, decrease, or remain unaffected as specimen thickness is increased.

With respect to the paper book and the E-ink, reading on the LCD reduces the size of the pupil (APS) and the frequency of eye blink (BPS), and increases the perceived visual fatigue (VFS).
Although the Kindle Fire HD adopts a last generation LCD with IPS (in-plane switching) technology, advanced polarizing filter, and anti-glare technology, the.Blinks by the subjects were measured using the smart glass system.
We investigated (i) the number of blinks, (ii) the number of blink bursts, (iii) the blink burst rate, (iv) the blink duration, and (v) blink velocity as the candidates for the fatigue indices. The blink bursts were series of .The next generation of fatigue sensors seem more like something you’d wear to the gym.
They analyze sweat and measure skin temperature as well as glucose, lactate, sodium and potassium levels to produce real-time alerts about fatigue, dehydration and stress.
