Eye tracking technology has become increasingly important for psychological analysis, medical diagnosis, driver assistance systems, and many other applications. Various gaze-tracking models have been established by previous researchers. However, there is currently no near-eye display system with accurate gaze-tracking performance and a convenient user experience. In this paper, we constructed a complete prototype of the mobile gaze-tracking system ' Etracker ' with a near-eye viewing device for human gaze tracking...

Emotional deficits have been repetitively reported in Alzheimer's disease (AD) without clearly identifying how emotional processing is impaired in this pathology. This paper describes an investigation of early emotional processing, as measured by the effects of emotional visual stimuli on a saccadic task involving both pro (PS) and anti (AS) saccades. Sixteen patients with AD and 25 age-matched healthy controls were eye-tracked while they had to quickly move their gaze toward a positive, negative, or neutral image presented on a computer screen (in the PS condition) or away from the image (in the AS condition)...

Recent studies suggest that circumscribed interests (CI) in females with Autism Spectrum Disorder (ASD) may align more closely with interests reported in typical female development than those typically reported for ASD males. We used eye-tracking to quantify attention to arrays containing combinations of male, female and neutral images in elementary-aged males and females with and without ASD. A number of condition × sex effects emerged, with both groups attending to images that corresponded with interests typically associated with their biological sex...

The digitalization of modern imaging has led radiologists to become very familiar with computers and their user interfaces (UI). New options for display and command offer expanded possibilities, but the mouse and keyboard remain the most commonly utilized, for usability reasons. In this work, we review and discuss different UI and their possible application in radiology. We consider two-dimensional and three-dimensional imaging displays in the context of interventional radiology, and discuss interest in touchscreens, kinetic sensors, eye detection, and augmented or virtual reality...

This study sought to determine differences in fencers' visual perceptions during duels (preparatory actions) with right- versus left-handed opponents. Participants were 12 top-ranking right-handed female foil fencers (aged 16-30 years, M = 20.86, SD = 4.76) taking part in a training camp. Testing employed SensoMotoric Instruments Eye Tracking Glasses (SMI ETG 2.0) with eye-tracking analyses covering the visual attention time devoted to various areas of the opposing fencer's body (areas of interest), average fixation, number of glances, and number of fixations during preparatory actions in duels...

OBJECTIVE: The objective of this study is to quantify the effect of the Bone Conduction Implant (BCI) on sound localisation accuracy in subjects with conductive hearing loss (CHL). DESIGN: The subjects were tested in a horizontal sound localisation task in which localisation responses were objectively obtained by eye-tracking, in a prospective, cross-sectional design. The tests were performed unaided and unilaterally aided. The stimulus used had a spectrum similar to female speech and was presented at 63 and 73 dB SPL...

Background: Malignant hyperthermia is a rare but potentially fatal complication of anesthesia, and several different cognitive aids designed to facilitate a timely and accurate response to this crisis currently exist. Eye tracking technology can measure voluntary and involuntary eye movements, gaze fixation within an area of interest, and speed of visual response and has been used to a limited extent in anesthesiology. Methods: With eye tracking technology, we compared the accessibility of five malignant hyperthermia cognitive aids by collecting gaze data from twelve volunteer participants...

Recent studies on the human eye indicate that the pupil moves inside the eyeball due to deformations of the iris. Here we show that this phenomenon can be originated by inertial forces undergone by the iris during the rotation of the eyeball. Moreover, these forces affect the iris in such a way that the pupil behaves effectively as a massive particle. To show this, we develop a model based on the Newton equation on the noninertial reference frame of the eyeball. The model allows us to reproduce and interpret several important findings of recent eye-tracking experiments on saccadic movements...

Although past theoretical work has proposed age-related gains in emotion regulation, the empirical evidence is not entirely consistent. In two laboratory studies, we investigated age differences in regulating negative emotions through attentional deployment by instructing participants to direct their attention either toward negative (up-regulation) or neutral (down-regulation) pictorial content. The regulation process (visual attention) was measured via eye-tracking and the regulation outcome (emotional experience) was assessed via self-report...

At least three distinct variants of primary progressive aphasia (PPA) have been described, but they are difficult to distinguish early in the course, when individuals experience primarily anomia. People with svPPA are often the hardest to care for, because they have impaired comprehension of words and objects and often have negative changes in comportment. We sought to identify an early marker of semantic variant primary progressive aphasia (svPPA) and to enhance the understanding of the semantic deficit in svPPA...

In two eye tracking experiments, we tested fourth graders' and adults' sensitivity to gender feature mismatches during reading of pronouns and their susceptibility to interference of feature-matching entities in the sentence. In Experiment 1, we showed children and adults two-phrase sentences such as "Leon{m}/Lisa{f} shooed away the sparrow{m}/the seagull{f} and then he{m} ate the tasty sandwich." Eye tracking measures showed no qualitative differences between children's and adults' processing of the pronouns...

Eye-tracking is an important approach to collect evidence regarding some participants' driving fatigue. In this contribution, the authors present a non-intrusive system for evaluating driver fatigue by tracking eye movement behaviours. A real-time eye-tracker was used to monitor participants' eye state for collecting eye-movement data. These data are useful to get insights into assessing participants' fatigue state during monotonous driving. Ten healthy subjects performed continuous simulated driving for 1-2 h with eye state monitoring on a driving simulator in this study, and these measured features of the fixation time and the pupil area were recorded via using eye movement tracking device...

It has been suggested that altered processing of emotion during cognitive control plays an important role in the etiology of depressive symptoms. The current study investigates the influence of emotional stimuli on working memory (WM) in adolescents with dysphoric symptomatology (DS). Twenty-five adolescents with DS and 40 adolescents with no dysphoric symptomatology (NDS) completed a memory-guided eye movement task. This task assessed the influence of irrelevant affective information on WM processes during high and low cognitive load...

OBJECTIVE: Using a well-established measure of attention, we aimed to objectively identify differences in severity between types of simulated secondary cleft lip deformities. DESIGN: Volunteer participants viewed a series of images of a child digitally modified to simulate different secondary unilateral cleft lip deformities (long lip, short lip, white roll/vermilion disjunction, and vermilion excess), a lip scar with no secondary deformity, or a normal lip. Eye movements were recorded using a table-mounted eye-tracking device...

In chronometric mental rotation tasks, sex differences are widely discussed. Most studies find men to be more skilled in mental rotation than women, which can be explained by the holistic strategy that they use to rotate stimuli. Women are believed to apply a piecemeal strategy. So far, there have been no studies investigating this phenomenon using eye-tacking methods in combination with electroencephalography (EEG) analysis: the present study compared behavioral responses, EEG activity, and eye movements of 15 men and 15 women while solving a three-dimensional chronometric mental rotation test...

Facial expressions are inherently dynamic cues that develop and change over time, unfolding their affective signal. Although facial dynamics are assumed important for emotion recognition, testing often involves intense and stereotypical expressions and little is known about the role of temporal information in the recognition of subtle, non-stereotypical expressions. In Experiment 1 we demonstrate that facial dynamics are critical for recognizing subtle and non-stereotypical facial expressions, but not for recognizing intense and stereotypical displays of emotion...

Brain tumour detection and diagnosis requires clinicians to inspect and analyse brain magnetic resonance images. Eye-tracking is commonly used to examine observers' gaze behaviour during such medical image interpretation tasks, but analysis of eye movement sequences is limited. We therefore used ScanMatch, a novel technique that compares saccadic eye movement sequences, to examine the effect of expertise and diagnosis on the similarity of scanning patterns. Diagnostic accuracy was also recorded. Thirty-five participants were classified as Novices, Medics and Experts based on their level of expertise...
