A framework for evaluating mHealth tools for Older Patients on Usability

Area of Science:

• Gerontology
• Human-Computer Interaction
• Digital Health

Background:

• The aging population experiences declines in sensory, physical, and cognitive functions.
• Mobile health (mHealth) applications offer potential benefits for older patients.
• Current mHealth app design guidelines often overlook age-related impairments, particularly for touch screen interfaces.

Purpose of the Study:

• To identify specific aging barriers affecting older adults' usability of mHealth apps.
• To propose a conceptual framework for understanding these age-related challenges.
• To inform the redesign of mHealth applications for better user experience in older populations.

Main Methods:

• Development of a conceptual framework based on cognitive, motivational, physical, and visual impairments in older adults.
• Analysis of usability issues within an mHealth app through the lens of this framework.
• Identification of how aging barriers manifest as specific usability problems.

Main Results:

• The study revealed distinct aging barriers related to sensory, physical, and cognitive declines impacting mHealth app use.
• Usability issues in touch screen interfaces were directly linked to these age-related impairments.
• A deeper understanding of the interplay between aging and usability was established.

Conclusions:

• Existing mHealth app design guidelines are insufficient for older users.
• Addressing specific aging barriers is crucial for developing effective and accessible mHealth solutions for the elderly.
• This research provides actionable insights for developers to create more inclusive mHealth applications.
