Accessibility

Accessibility Thorium Reader is for everyone, including people who are blind or have other types of visual, cognitive or motor disabilities. The application is compatible with accessible technologies like screen readers, including JAWS, NVDA, Narrator and VoiceOver. It includes a read-aloud feature with visual highlighting. Thorium Reader can be used with the mouse or the keyboard, and keyboard shortcuts are configurable. The display can be customized to meet the needs of users, including colors, text size, spacing, font and layout.

Reading with a screen reader

Reading with a screen reader When launching Thorium, if a screen reader is detected, the relative functions are activated. Note that screen readers use a separate buffer to access the HTML content which results in the visual scroll / page offset to be out of sync. In other words, Thorium is generally not aware of the user's current reading location inside the screen reader buffer, unless the screen reader user triggers standard web API events (such as mouse click anywhere in the text, or keyboard tab into focusable HTML elements).

Frequently asked questions

Why can't I open an ebook without it being save in the Thorium Reader library? Thorium, like several other ebook readers and reading systems stores imported publications in its own filesystem space, as this provides a guarantee that per-publication state and external metadata (e.g. bookmarks, settings, annotations, DRM status, etc.) can be reliably attached. If you need to open files without using advanced reading features, and want to keep a manual maintenance of ebook files, you can consider using an alternative.
