Effects of transient blur and VDT screen luminance changes on eyeblink rate.
PURPOSE A study was designed to evaluate the efficacy of three different strategies aiming at increasing spontaneous eyeblink rate (SEBR) during computer use. METHODS A total of 12 subjects (5 female) with a mean age of 28.7 years were instructed to read a text presented on a computer display terminal during 15min. Four reading sessions (reference and three "blinking events" [BE]) were progra...
متن کاملPupillary Response Based Cognitive Workload Measurement under Luminance Changes
Pupillary response has been widely accepted as a physiological index of cognitive workload. It can be reliably measured with remote eye trackers in a non-intrusive way. However, pupillometric measurement might fail to assess cognitive workload due to the variation of luminance conditions. To overcome this problem, we study the characteristics of pupillary responses at different stages of cognit...
متن کاملLuminance of the surround and visual fatigue of VDT operators.
Luminance distribution in the visual field is considered as one of causal factors with a significant influence on visual fatigue, especially for intensive and extended Video Display Terminal (VDT) work. The aim of the study was to define visual fatigue of VDT operators for different values of surrounding luminance. Experiments were carried out in laboratory conditions under 3 lighting condition...
متن کاملPupillary Response: Removing Screen Luminosity Effects for Clearer Implicit Feedback
Pupillary dilation measured by eye-tracking can be useful source of implicit feedback for system adaptation and personalization. For example, cognitive load or emotional excitation can be inferred from it. However, practical exploitation of this phenomenon (e.g., in adaptive systems or user studies) has been limited due to other factors that influence pupillary dilation, namely changing luminos...
متن کاملPrimate pupillary light reflex: receptive field characteristics of pretectal luminance neurons.
This study examined the response properties of luminance neurons found within the pretectal olivary nucleus (PON), which is the pretectal nucleus that mediates the primate pupillary light reflex. We recorded the activity of 121 single units in alert, behaving rhesus monkeys trained to fixate a back-projected laser spot while a luminance stimulus was presented. The change in the firing rate of l...
