简介：

Overview

This paper presents a novel automated method for assessing visual acuity in infants and toddlers using an eye-tracking system. The method is particularly useful for young children who have not yet developed sufficient communication skills.

Key Study Components

Area of Science

• Visual acuity assessment
• Child development
• Eye-tracking technology

Background

• Visual acuity is crucial for early childhood development.
• Traditional methods may not be suitable for very young children.
• Automated procedures can enhance assessment accuracy.
• Eye-tracking technology offers a non-invasive solution.

Purpose of Study

• To evaluate visual acuity in infants and toddlers.
• To develop a method that accommodates non-verbal children.
• To improve the reliability of visual assessments.

Methods Used

• The automated acuity card procedure (AACP) was utilized.
• A webcam was employed instead of a remote eye tracker.
• A two-choice looking test was implemented.
• Cartoon images served as visual rewards during testing.

Main Results

• The AACP effectively recognized children's watching behaviors.
• The method reduced misstatements caused by eye movements.
• Visual stimuli were engaging for the children.
• The procedure demonstrated reliability in assessing visual acuity.

Conclusions

• The AACP is a promising tool for assessing visual acuity in young children.
• It addresses the challenges of traditional assessment methods.
• Future research could expand its application in clinical settings.
