The mass digitization of books is changing the way information created, disseminated and displayed. Electronic book readers (e-readers) generally refer to two main display technologies: electronic ink (E-ink) liquid crystal (LCD). Both technologies have advantages disadvantages, but question whether one or other triggers less visual fatigue still open. aim present research was study effects technology on fatigue. To this end, participants performed a longitudinal in which last generation...

This article proposes a method based on wavelet transform and neural networks for relating pupillary behavior to psychological stress. The proposed was tested by recording pupil diameter electrodermal activity during simulated driving task. Self-report measures were also collected. Participants performed baseline run with the task only, followed three stress runs where they required perform along sound alerts, presence of two human evaluators, both. Self-reports successfully indexed...

We hypothesize that the fundamental difference between expert and learner musicians isthe capacity to efficiently integrate cross-modal information. This might be anindex of an memory using both auditory visual cues built during many years oflearning extensive practice. Investigating this issue through eye-tracking experiment, two groups musicians, experts non-experts, were required report whether afragment classical music, successively displayed auditorily visually on a computer screen...

Abstract. This paper presents a new methodology for studying cognition, which combines eye movements (EM) and event-related potentials (ERP) to track the cognitive processes that occur during single fixation. technique, called eye-fixation-related (EFRP), has advantage of coupling accurate time measures from ERPs location on stimulus, so it can be used disentangle perceptual/attentional/cognitive factors affecting reading. We tested this technique describe controversial parafoveal-on-foveal...

Expertise is associated with a knowledge-driven information processing approach. Experts benefit from long-term knowledge structures—chunks and retrieval structures/templates—leading them to formulate expectations about local stimulus characteristics extract projected onto distant areas the fixation location. In an attempt shed light on way impacts eye movements during music reading, this study aimed determine how expert musicians deal complexity in sight-reading task. Thirty two expertise...

This paper proposes an automatic method for predicting the inter-observer visual congruency (IOVC). The IOVC reflects congruence or variability among different subjects looking at same image. Predicting this is of interest image processing applications where perception a picture matters such as website design, advertisement, etc. makes several new contributions. First, computational model proposed. mixture low-level features extracted from input model's parameters are learned by using large...

Eye fixation-related potential (EFRP) measures electrical brain activity in response to eye fixations. The aim of the current study was investigate whether EFRPs vary during consecutive fixations while subjects were performing an object identification task. evoked P1 and N1 components at occipital parietal recording sites. latency component increased amplitude decreased results indicate that are modulated fixations, suggesting technique may provide a useful tool temporal dynamics visual...

Overt visual attention is the act of directing eyes toward a given area. These eye movements are characterised by saccades and fixations. A debate currently surrounds role Do they all have same in free viewing natural scenes? Recent studies suggest that at least two types fixations exist: focal ambient. The former believed to be used inspect local areas accurately, whereas latter obtain context scene. We investigated use an automated system cluster groups using four scene images. found new...

It is often said that experienced musicians are capable of hearing what they read (and vice versa). This suggests able to process and integrate multimodal information. The present study investigates this issue with an eye-tracking technique. Two groups chosen on the basis their level expertise (experts, non-experts) had excerpts poorly-known classical piano music play them a keyboard. experiment was run in two consecutive phases during which each excerpt (1) without playing (2) sight-read...

Reading on a web page is known to be not linear and people need make fast decisions about whether they have stop or reading. In such context, reading, decision-making processes are intertwined this experiment attempts separate them through electrophysiological patterns provided by the Eye-Fixation-Related Potentials technique (EFRPs). We conducted an in which EFRPs were recorded while participants read blocks of text that semantically highly related, moderately unrelated given goal....

In this paper, we describe a new algorithm that consists in combining an eye-tracker for minimizing the fatigue of user during evaluation process Interactive Evolutionary Computation. The approach is then applied to One-Max optimization problem.

The present study utilized a novel methodological combination of eye tracking and postural movement recordings to task-induced changes in cognitive engagement during expository text reading. Thirty-three participants read an with specific task mind while their movements were concurrently recorded, after reading recalled the from memory. results showed that readers spent longer total fixation time had better memory for task-relevant than irrelevant information. During course reading,...
