Eye gaze tracking has recently become indispensable for domains like virtual reality, augmented reality, human-computer interaction and advertisement. The commercial eye gaze tracking equipment is too expensive to be used by the masses. In this manuscript, a non-invasive, low-resolution ordinary camera-based system has been proposed for tracking…

Simplified user interfaces (SUIs) refer to a new design technique in technical communication that simplifies screenshots by removing irrelevant elements and highlighting only the essential information. While there is consensus on the benefits of signaling in multimedia learning, there is currently no empirical evidence on the effects of SUIs on…

Problem solving is one of the high-level thinking skills and essential in teaching mathematical concepts and procedures. The eye-tracking method allows educators to see and interpret different problem-solving behaviours of students. The purpose of this study was to investigate the problem-solving behaviours of university students based on eye…

The study of infant gaze has long been a key tool for understanding the developing mind. However, labor-intensive data collection and processing limit the speed at which this understanding can be advanced. Here, we demonstrate an asynchronous workflow for conducting violation-of-expectation (VoE) experiments, which is fully "hands-off"…

Eye movement patterns and consistency during face recognition are both associated with recognition performance. We examined whether they reflect different mechanisms through EEG decoding. Eighty-four participants performed an old-new face recognition task with eye movement pattern and consistency quantified using eye movement analysis with hidden…

In this study, the authors examined the impact of irrelevant visual images in a PowerPoint lecture on attention and information retention performance. They found students viewing text-only PowerPoint slides retained less information than students viewing text-and-image slides, but the difference did not reach significance. However, when examining…

Purpose: This study aimed to evaluate the reliability of different approaches for estimating the articulation rates in connected speech of Parkinsonian patients with different stages of neurodegeneration compared to healthy controls. Method: Monologues and reading passages were obtained from 25 patients with idiopathic rapid eye movement sleep…

The availability of powerful head-mounted displays (HMDs) has made virtual reality (VR) a mainstream technology and spearheaded the idea of immersive virtual experiences within the Metaverse -- a shared and persistent virtual world. Companies are eagerly investing in various VR products and services, aiming to be early adopters and create new…

This study proposes a software system for determining gaze patterns in on-screen testing. The system applies machine learning techniques to eye-movement data obtained from an eye-tracking device to categorize students according to their gaze behavior pattern while solving an on-screen test. These patterns are determined by converting eye movement…

What can eye movements reveal about reading, a complex skill ubiquitous in everyday life? Research suggests that gaze can reflect short-term comprehension for facts, but it is unknown whether it can measure long-term, deep comprehension. We tracked gaze while 147 participants read long, connected, informative texts and completed assessments of…

This study investigated the design processes for developing eye training materials for children with low vision (CLV) using computer game applications based on eye movement tracking to enhance their vision skills. The primary aim was to create interactive eye training materials tailored to improve CLV's vision abilities. Employing a design-based…

Purpose: The purpose of this study is to design and implement an intelligent online proctoring system (IOPS) by using the advantage of artificial intelligence technology in order to monitor the online exam, which is urgently needed in online learning settings worldwide. As a pilot application, the authors used this system in an authentic…

This analysis investigates two differential "PowerPoint" slide designs--presentation and teleprompter--for multimedia learning. Eye tracking measures assessed differences in fixations. Participants demonstrated greater fixation counts for teleprompter slides, measures of aesthetic liking evidenced that slides incorporating imagery…

Purpose: Augmentative and alternative communication (AAC) systems are important to support communication for individuals with complex communication needs. A recent addition to AAC system options is the brain-computer interface (BCI). This study aimed to compare the clinical application of the P300 speller BCI with two more common AAC systems, the…

This study examines interactions between students with atypical motor and speech abilities, their teachers, and eye tracking devices under varying conditions typical of educational settings (e.g., interactional style, teacher familiarity). Twelve children (aged 4-12 years) participated in teacher-guided sessions with eye tracking software that are…
