Focusable Element

A GUI element that can receive input focus, allowing users to interact with it via keyboard, switch device, or assistive technology. For screen reader users navigating mobile apps, an element without focus enabled is essentially invisible—they cannot select, activate, or even know it exists. Lack of element focus is the single largest source of accessibility violations in mobile apps, accounting for over 53% of violations in large-scale studies. Developers must explicitly set focus properties for interactive elements, as some widgets are not focusable by default.
