> Is there any research done on this?

BeeLine [0] claims to be backed by research and employs a similar device. Seems to be a new idea, and I wanted to experiment.

Interesting. I saw the Beeline Reader before and their method is different in a way that doesn't negatively impact my reading. Their grayscale palette is actually fun and unobtrusive enough that I forget it exists after a while.

Also, their text is left-aligned.

If you're up for more experiments, try a line highlighter that follows a cursor, like so: https://blog.adobe.com/en/publish/2021/05/06/hacking-readabi...

I just did the "challenge" at BeeLine and they are not using right-justified text or even mentioning it. What "similar device" are you talking about?

BeeLine founder here! I would guess that parent is referring to the fact that BeeLine assists with visual tracking during line transitions, and having a ragged edge (as opposed to justified) helps with this also. I've not seen people use right-justification as a way to achieve this, but the general consensus is that line transitions are easier when there's a ragged edge instead of justified text.

Oh hey! The funny thing is, I originally contacted BeeLine for a quote but was refused one without an already-existing website. So I resorted to experimenting with right-justification.

Please shoot me an email — happy to make this happen for you.
