Gaze-Based Assistive Technology for a Toddler with Tetraplegia and Without Speech

Area of Science:

• Pediatric Rehabilitation
• Assistive Technology
• Developmental Pediatrics

Background:

• Early intervention is critical for children with severe physical impairments and non-verbal status.
• Augmentative and alternative communication (AAC) offers potential communication pathways.
• Gaze-based AAC systems are a technologically advanced option for individuals with limited motor control.

Observation:

• A ten-month-old non-verbal infant with severe physical impairments was enrolled in a case study.
• Data collection involved longitudinal methods including questionnaires, video recordings, and field observations.
• The study tracked the child's progress from infancy until three years of age.

Findings:

• Gaze-based AAC was explored as an early intervention strategy.
• The intervention focused on a single case to understand individual developmental trajectories.
• Consistent data collection provided a detailed developmental timeline.

Implications:

• Findings suggest gaze-based AAC can be a viable early intervention for non-verbal children with physical disabilities.
• This case study highlights the importance of individualized and timely AAC implementation.
• Further research with larger cohorts is warranted to generalize findings on gaze-based AAC effectiveness.
