“…In particular, we cannot exclude that the Pupil Near Response (PNR)which entails pupil-size changes -was triggered at random points in time. In addition, it has been reported that in darkness and/or in the absence of direct external stimuli, the size of the pupil can fluctuate with frequencies around 0.5-1.0 Hz and amplitudes of the order of a few percent (Köles, 2017;Sirois & Brisson, 2014;Mathôt et al, 2018). In order to estimate the extent to which pupil size was fluctuating over the time course of our experiments, for all recordings and all three measurement methods, we calculated the standard deviation of relative pupil size over a time window of 10 s prior to the sweep period (see Fig.…”

Gaze-angle dependency of pupil-size measurements in head-mounted eye tracking

Pupillometry - the study of temporal changes in pupil diameter as a function of external light stimuli or cognitive processing - requires the accurate and gaze-angle independent measurement of pupil dilation. Expected response amplitudes often are only a few percent relative to a pre-stimulus baseline, thus demanding for sub-millimeter accuracy. Video-based approaches to pupil-size measurement aim at inferring pupil dilation from eye images alone. Eyeball rotation in relation to the recording camera as well as optical effects due to refraction at corneal interfaces can, however, induce so-called pupil foreshortening errors (PFE), i.e. systematic gaze-angle dependent changes of apparent pupil size that are on a par with typical response amplitudes. While PFE and options for its correction have been discussed for remote eye trackers, for head-mounted eye trackers such an assessment is still lacking. In this work, we therefore gauge the extent of PFE in three measurement techniques, all based on eye images recorded with a single near-eye camera. We present both real world experimental data as well as results obtained on synthetically generated eye images. We discuss PFE effects at three different levels of data aggregation: the sample, subject, and population level. In particular, we show that a recently proposed refraction-aware approach employing a mathematical 3D eye model is successful in providing pupil-size measurements which are gaze-angle independent at the population level.

“…It should be noted that emotion dysregulation is common in individuals with ADHD, characterized by excessive and rapidly shifting emotions, often associated with irritable and aggressive behavior (29). Pupil reactivity is also influenced by ongoing cognitive processsing, fatigue, intelligence, and working memory (30). The studies related to PLR changes in children suffering from ADHD are rare.…”

“…Moreover, pupil size correlated with indicators of attention: the subjects'performance and reaction time variability (31). Thus, in studies using pupillometry these factors should be considered to obtain reliable parameters and results (30). Changes in pupil size and response to light can be also an indication of drug and medicine consumption.…”

Attention deficit/hyperactivity disorder (ADHD) is one of the most frequently seen mental disorders in children with an increasing risk for other mental disorders. ADHD represents a primary biological dysfunction of the central nervous system, such as dysregulation of frontal-subcortical-cerebellar catecholaminergic circuits and imbalances in the dopaminergic system. However, autonomic nervous system, comprised of two primary branches - sympathetic and parasympathetic nervous systems that are normally in dynamic balance, plays an essential role in the regulation of body functions. Although it is generally assumed that the autonomic regulation is impaired during ADHD the information related to this dysregulation is limited. One of the options to observe changes of autonomic balance in ADHD is pupillary light reflex (PLR). Pupillometric evaluation can be used for the assessment of functioning of both autonomic nervous system branches and certain parameters of pupil responsivity can be helpful as a tool for medical diagnostic and treatment. In conclusion, these findings suggest the pupillometry as a non-invasive method that can indicate abnormalities in the complex central autonomic network regulating PLR.

“…In particular, it was observed that the more demanding a cognitive task is, the greater the pupil dilation is [13]- [15]. In addition, researchers have explored the application of pupil dilation in several human computer interaction scenarios [16] and also in some code comprehension studies [17].…”

Recent eye tracking research in the field of software engineering has proposed novel visualizations linking developer's gazes with the source code artifacts to better understand how developers comprehend source code artifacts potentially consisting of several different files. In addition, it is well established that cognitive processes can be monitored by recording the change in pupil dilation. Recent pupillometry studies in the software engineering field have shown that pupil dilation can be used either as an indicator of cognitive load or task difficulty. We envision to create a tool for visualizing pupil dilation linked to source code artifacts that can help to better understand the cognitive processes of a developer during code comprehension tasks in terms of cognitive load. In this paper, we describe a feasibility study we conducted to enable a more fine-grained analysis of pupil dilation and we demonstrate some preliminary results.
