Native Mobile Accessibility
Accessibility involves providing all of your users with a consistent experience regardless of their abilities. This requires designing for users with disabilities so they can perceive, understand, navigate, and interact with interfaces - both physical and digital. I was first introduced to Accessibility when exploring the Settings menu on my iPhone. It was after using a few of the features that I realized how the iPhone highlights the abilities in all people. Since then, I've been following WAI-Aria for my websites, volunteer to help the disabled community and have explored the world of native mobile accessibility.
