Parametric Cognitive Modeling of Information and Computer Technology Usage by People with Aging- and...

Area of Science:

• Human-Computer Interaction
• Cognitive Science
• Accessibility Engineering

Background:

• Information and Computer Technology (ICT) development lacks structured tools for universal design.
• Designers struggle to adapt products to diverse user needs, especially those with functional impairments.
• Existing design processes do not adequately incorporate cognitive and perceptual aspects for aging and disability.

Purpose of the Study:

• To define and evaluate parametric cognitive models for ICT interaction by individuals with functional impairments.
• To develop virtual user models simulating aging and disability for product design.
• To assess the benefits of these models in designing accessible ICT applications and services.

Main Methods:

• Analytical study to identify cognitive functions and parameters related to functional impairments.
• Development of a multisensorial training platform using real user measurements.
• Training of virtual parameterized user models on the platform.
• Evaluation of cognitive virtual user models in a real application scenario.

Main Results:

• Parametric cognitive models effectively describe ICT interaction for users with functional impairments.
• Virtual user models accurately simulate user behavior under conditions of aging and disability.
• The use of these models provides concrete benefits to the design and testing of accessible ICT.
• Parameterization successfully incorporates cognitive and perceptual factors into the design process.

Conclusions:

• Parametric cognitive models offer a structured approach to universal design in ICT.
• Virtual user models enhance the creation of inclusive and user-centered ICT products.
• This methodology supports the development of accessible ICT applications and services for diverse user groups.
