BackgroundProsthetic control requires not only motor execution but also the development of adaptive visual strategies. Myoelectric prostheses provide limited sensory feedback and therefore rely more heavily on visual monitoring. However, learning-related changes in gaze behavior—including fixation patterns and physiological indices such as blink rate—remain underexplored. This study aimed to investigate how gaze behavior changes and the sense of ownership change during the learning of body-powered and myoelectric prosthetic control, and how these effects...자세히 보기

Objective Eye-tracking technology has been increasingly investigated as an objective approach for distinguishing individuals with Autism Spectrum Disorder (ASD) from typically developing (TD) individuals. Artificial intelligence and machine learning (ML) methods have been widely applied to support ASD diagnosis and treatment, and prior studies suggest that ML models leveraging eye-tracking data can achieve high diagnostic accuracy. This systematic review and meta-analysis aimed to evaluate the diagnostic performance of machine-learning models using eye-t...자세히 보기

BackgroundIndividuals who experience severe speech and physical impairment face significant challenges in communication and daily interaction. Visual brain–computer interfaces (BCIs) offer a potential assistive solution, but their usability is limited when facing restrictions in eye motor control, gaze redirection and fixation. This study investigates the feasibility of a gaze-independent visual oddball BCI for use as an augmentative and alternative communication (AAC) device in the presence of limited eye motor control.MethodsSeven participants with var...자세히 보기

Amblyopia, characterized by monocular visual deficits and impaired binocularity, attention, and oculomotor control, is often considered untreatable in adulthood due to reduced neuroplasticity. Conventional therapies target children within the critical period. This study investigated transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (dlPFC) as a novel intervention to modulate attentional networks and saccadic performance in adults with amblyopia. Thirty adults (20--35 years) with unilateral amblyopia were randomized in...자세히 보기

Enhancing patient engagement is essential for effective post-stroke robotic rehabilitation, yet limited effort has been made towards modulating and quantifying patient engagement during therapy. To Bridge this gap, we introduce a virtual reality (VR)-integrated robot-assisted system for upper limb rehabilitation, which innovatively enables simultaneous modulation and monitoring of user engagement in a line tracing task. Modulation is governed by two parameters: shape complexity and force noise disturbance level. Our system estimates engagement using phys...자세히 보기

Purpose: To validate the accuracy of a lens-viewpoint extraction method and demonstrate its feasibility for tracking users' visual behavior on progressive addition lenses (PALs). This aims to provide a quantifiable fitting solution for PAL wearers in the future. Methods: We evaluated a method using eye-tracking technology to extract the viewpoint on the lens, implemented with a self-made setup. Accuracy verification experiments were performed using a mechanical artificial eye, and a clinical test on 10 subjects was performed to assess the accuracy of the...자세히 보기

Purpose: People with central vision loss (CVL) often adopt a preferred retinal locus (PRL) for fixation outside the region of central loss. However, it is unknown how often the fixational PRL (fPRL) is used in reading. Here, we assessed if the reading PRL is in the same location as the fPRL.Methods: Participants read text on a computer screen. Reading was randomly interrupted by blanking the screen, and participants reported the word being read when the blanking occurred. The location of this word was compared to the fPRL location, measured with an eye t...자세히 보기

Background: Childhood obesity and mental health problems are major public health concerns worldwide. Early-life exposure to green spaces has been shown to promote physical activity, reduce obesity risk, and improve cognitive and emotional development. Schoolyards offer a unique opportunity to promote health, as children spend a large proportion of their time at school. Methods: This quasi-experimental protocol study investigates the effects of transforming gray schoolyards into biodiverse green spaces on children’s health and well-being. Four primary sch...자세히 보기

Visual impairments, such as cataracts, pose a global challenge with preventable cases and unaddressed issues due to limited eye care understanding. In this work, we investigate cataracts using a virtual reality simulation, exploring its impact on a visual search task and investigating the correlations between eye movement features and the severity of the simulation. We simulated cataract progression in one or both eyes through two studies utilizing virtual reality and eye tracking. We analyzed the impact on task performance and eye movements and found th...자세히 보기

PURPOSE: To measure eye fixation preference in patients with intermittent exotropia using a wearable binocular eye tracker that records the position of each globe within the orbit.DESIGN: Prospective assessment validity analysis.SUBJECTS: Forty patients referred to a single pediatric ophthalmologist for evaluation of intermittent exotropia.METHODS: Ambulatory patients wore eye tracking glasses for up to 12 hours to monitor their ocular alignment while carrying out their usual daily activities. Histograms were prepared of each eye's horizontal position as...자세히 보기

Background/Objectives: This study's objective was to analyze the reading ability in patients with intermittent exotropia using an eye tracker and determine how the clinical characteristics of intermittent exotropia may affect reading ability. Methods: We compared the reading speed (LPS; letters per second) of 25 intermittent exotropia patients to 25 age-matched normal controls who were 13 years old or older with best-corrected visual acuities of ≥20/25. Correlations between reading ability and clinical characteristics of intermittent exotropia were evalu...자세히 보기

INTRODUCTION: Early-onset chronic liver disease (CLD) and its subsequent clinical progression have systemic impact. Its trajectory coincides with critical periods of brain development. In this study, we will test the hypothesis that early-onset CLD is associated with neurodevelopmental and psychiatric symptoms and delineate their neurobiological underpinnings through multimodal neuroimaging.METHODS AND ANALYSIS: This study will recruit 100 patients with biliary atresia and 50 patients with other types of early-onset CLD, aged between 6 and 30 years, unde...자세히 보기
