Establishment of open web platform based on 3D head model for product adaptability analysis and evaluation

Area of Science:

• Ergonomics
• Human-Computer Interaction
• Product Design

Background:

• Increasing demand for wearable headwear necessitates improved design methods beyond traditional 1D anthropometry.
• Current 1D design approaches lead to poor adaptability and user comfort for 3D head shapes.

Purpose of the Study:

• To develop a 3D-aided design platform for evaluating headwear virtual wearing and adaptability.
• To enhance the fit and comfort of headwear products through advanced digital tools.

Main Methods:

• Development of a WebGL-based service, the Chinese Headwear Adaptability Testing (CHAT) platform.
• Utilizing a 3D standard head shape for virtual fitting and adaptability assessments.
• Validation through user studies with a redesigned eye massager device.

Main Results:

• The CHAT platform facilitated the redesign of an eye massager.
• Significant improvements in wearing comfort and adaptability were observed post-redesign.
• The virtual testing approach proved effective in optimizing headwear fit.

Conclusions:

• The CHAT platform offers a viable solution for improving headwear design and user comfort.
• 3D virtual testing is crucial for achieving optimal fit and adaptability in headwear products.
• This approach can lead to more user-centric and comfortable wearable products.
