A 3D anthropometry-based quantified comfort model for children's eyeglasses design

Area of Science:

• Ergonomics
• Human-Computer Interaction
• Biomechanical Engineering

Background:

• Designing personalized ergonomic products, like children's eyeglasses, requires understanding user comfort.
• Quantified models linking physical parameters to comfort perception are crucial but underexplored for pediatric eyewear.

Purpose of the Study:

• To investigate children's comfort perceptions related to eyeglass nose pad width and temple clamping force.
• To establish quantified models connecting subjective comfort to objective anthropometric and product parameters for children's eyeglasses.

Main Methods:

• A psychological experiment involving 30 child participants was conducted.
• Two key variables (nose pad width, temple clamping force) were manipulated to assess comfort.
• Mathematical trendlines and surfaces were developed to model the relationships.

Main Results:

• Both nose pad width and temple clamping force significantly impacted children's comfort perceptions.
• Minor differences in comfort were observed between static and dynamic conditions.
• Established models accurately estimate comfort scores based on 3D parameters.

Conclusions:

• This research provides the first quantified relationships for ergonomic children's eyeglass design.
• The models enable calculation of parameter allowances for optimal sizing and grading.
• Findings support mass customization and personalization of pediatric eyewear for enhanced comfort.
