What This Panel Does

Reading Preferences is the third button, the open book. It holds the two settings that help you stay with the text: Line Focus and the Picture Dictionary. Translation lives here too, and has its own guide.


Who is This For?

This is helpful for:

  • Anyone whose eye jumps to the wrong line in a block of text
  • Readers who meet words they cannot picture
  • Students reading in a second language
  • Anyone who reads a paragraph and realises they took none of it in

Open Reading Preferences

Open Immersive Reader first. You can start it from the floating toolbar, from the Helperbird menu, or from the Tools menu in the PDF Reader.

Once it is open, the three buttons in the top-right corner hold every setting.

Click the book button.

The Reading Preferences panel in Immersive Reader, with line focus, the picture dictionary and translation


Line Focus

Turn on Line Focus and everything except the line you are reading is dimmed.

Underneath are three widths: one line, three lines, or five lines. One line is the most focused and the most work, because you move it constantly. Three is a good middle. Five keeps some context around you.

Start at three. If you still lose your place, go to one.


Picture Dictionary

On by default. Click any word while it is on and a picture of that word appears, from the Boardmaker symbol set.

It is most useful for concrete nouns, where a picture is quicker than a definition, and for anyone reading in a second language. It cannot illustrate an abstract word, so nothing will appear for something like "however".

For a full definition rather than a picture, use the Helperbird Dictionary.

Next: Text Preferences and Grammar Options.

students to have control over the...

This is my first google review ever! I have to share that the accessibility and support for independent access for students that Helperbird provides, is a game changer. It is constantly being updated with new features based on feedback and it is extremely user friendly. The ability to customize the settings allows students to have control over their own learning, aligning with Universal Design for Learning. Looking forward to sharing with students and fellow educators on a daily basis. Thanks, Helperbird team!
