PURPOSE To classify blinks in dry eye and normal subjects into six subtypes, and to define the blink rate and duration within each type of blink, as well as the total lid-contact time/minute. MATERIALS AND METHODS This was a single-centered, prospective, double-blind study of eleven dry-eye and ten normal subjects. Predefined subjects watched a video while blinks were recorded for 10 minutes....

EOG is a biosignal which occurs during eye activities such as eye movement and blink. EOG has a linear relationship with gaze distance. Detection object position in 3-dimensional area using gaze motion was proposed in this research. To calculate the distance of gaze motion in pixel unit, affine transform method was developed. The homogeneous matrix from five geometry processes: transformation-1...

<span lang="id">Blink detection is an important technique in a variety of settings, including facial motion analysis and signal processing. However, automatic blink challenging due to its rate. This paper proposes real-time method for detecting eye blinks video series. The based on landmark trained real-world datasets demonstrates robustness against various environmental factors, lighting...

This study shows how intelligence of an individual can be determined in different intelligence domains using brain and bio-signals. Results of pupil dilation, eye-blink and EEG (Electroencephalogram) signals were analyzed. It was found that high intelligent individuals (HI) could easily modulate their resource allocation and information processing strategy than low intelligent individuals (LI) ...

This paper presents comparison of two image processing algorithms used for eye blink detection. The motivation of this research work is the need of disabled persons who are unable to move their body parts except eyes. The process of blink detection is divided into three parts viz.face localization, eye pair localization and template matching method. In method 1, YCbCr color model and morphologi...

This study investigated the effect of moving from single-occupancy offices to a landscape environment. Thirty-two visual display unit (VDU) operators reported no significant change in visual discomfort. Lighting conditions and glare reported subjectively showed no significant correlation with visual discomfort. Experience of pain was found to reduce subjectively rated work capacity during VDU t...

Blinks are related to several emotional states, and the present report describes a simple, reliable way to measure blinks from the video stream of an eye obtained during eyetracking, where the source of the eye video is a video camera attached to a head-mounted eyetracker. Computer vision techniques are employed to determine the moments that a blink starts and ends, for the purpose of calculati...

It is well known that the measuring of pupil size is influenced by noises and blinking. This paper describes the development of an estimation model of pupil size for ’blink artifact’ which is based on a 3 layered perceptron with back propagation method. The model was trained by pupil responses with artificial blinks. It was found that pupil size during the blink period could be estimated accord...
