Abstract

Nowadays, there is a vast number of mobile devices capable of storing an individual’s entire life. There are applications for everything, from banking to ordering food and clothes, but also different health applications targeted towards different impairments and self-health care management. Self-health care management applications can have a significant impact on individuals with various diseases and impairments. However, it is essential that these applications are accessible to users with different impairments such as motor and vision impairments.

The purpose of this study was to examine accessibility concerns in mobile health applications for individuals with multiple sclerosis and evaluate how these concerns were addressed. Multiple sclerosis was chosen as the focus of this study because its symptoms encompass a range of impairments, including vision, motion, hearing, and cognitive limitations.

The study was conducted with benchmarking multiple sclerosis applications obtained in Google Play store. Benchmarking focused on accessibility, and measurements and metrics were gathered testing applications with Google Accessibility Scanner and TalkBack screen reader. Measurements were based on web content accessibility guidelines (WCAG) 2 and accessibility guidelines for mobile applications.

None of the tested applications followed accessibility guideline requirements based on benchmarking metrics. When examining the metrics from the perspective of impairments, it was found that applications had accessibility concerns related to motor and vision impairments. The applications addressed requirements for hearing impairments in applicable features, while testing cognitive impairment requirements proved challenging with the selected testing tools. In the future, it is recommended to conduct additional accessibility testing for cognitive impairments using methods such as manual accessibility testing and user testing.
