BACKGROUND: Avoidance to look others in the eye is a characteristic symptom of Autism Spectrum Disorders (ASD), and it has been hypothesised that quantitative monitoring of gaze patterns could be useful to objectively evaluate treatments. However, tools to measure gaze behaviour on a regular basis at a manageable cost are missing. In this paper, we investigated whether a smartphone-based tool could address this problem. Specifically, we assessed ...

Purpose. To create a binocular statistical eye model based on previously measured ocular biometric data. Methods. Thirty-nine parameters were determined for a group of 127 healthy subjects (37 male, 90 female; 96.8% Caucasian) with an average age of 39.9 ± 12.2 years and spherical equivalent refraction of −0.98 ± 1.77 D. These parameters described the biometry of both eyes and the subjects' age. Missing parameters were complemented by data from ...

It has been suggested that motor imagery possesses a range of useful applications in sport as well as in rehabilitation. Until now, research in this field has been hampered by the lack of an objective method to monitor the subjects' participation in the task. In this present study, a new approach to quantifying motor imagery of goal-directed hand movements by means of eye movement registration is examined. Eye movements of 15 right-handed ...

Research indicates that deliberate thinking and eye movements are related. However, how various thought processes influence eye movements is not explored well. The present research examined the role of convergent and divergent thinking in eye movement. Divergent thinking involves novel alternatives, multiple uses, and unconventional answers which may require scanning visual surroundings precisely and extensively. Hence, it was hypothesized that ...

To date, a number of studies have demonstrated the existence of mismatches between children's implicit and explicit knowledge at certain points in development that become manifest by their gestures and gaze orientation in different problem solving contexts. Stimulated by this research, we used eye movement measurement to investigate the development of basic knowledge about numerical magnitude in primary school children. Sixty-six children from ...

PURPOSE. Stochastic eye models are a method to generate random biometry data with the variability found in the general population for use in optical calculations. This work improves the accuracy of a previous model by including the higher-order shape parameters of the cornea. METHODS. The right eye biometry of 312 subjects (40.8 +/- 11.0 years of age) were measured with an autorefractometer, a Scheimpflug camera, an optical biometer, and a ray ...

Therapies such as EMDR or imagery rescripting (ImR) are two popular and effective interventions for dealing with trauma. Both EMDR and ImR rely heavily on changing the impact of autobiographical memories. In recent years, legal cases and clinical reports have shown that after therapy such as EMDR and ImR, patients "suddenly" report new memories of traumatic experiences. This could lead to patients erroneously claiming to have been, for example, ...

Despite the proven advantages, explanations are not yet mainstream in industry applications of recommender systems. One of the possible reasons for this lack of adaption is the risk of overwhelming end-users with the explanations. In this paper, we investigate whether it is possible to overcome the information overload problem by only showing explanations that are relevant to the user. To do so, we leverage the gaze of a user as a novel ...

Glaucoma is a chronic disease in ophthalmology, affecting 3% of the Belgian population. The most important risk-factor of glaucoma is an elevated intraocular pressure. Objective outcomes such as visual field and optic nerve defects only give limited information about the real impact of glaucoma and its treatment on a patients daily life. Therefore the patients perspective or so-called patient reported outcomes (PROs) are essential for evaluating ...
