Make scrolling frequency and search size user customizable? #10
Description
Adjusting frequency of how often we search for text and how much text we search (from captions and in accessibility tree) can improve the user experience.
For example:
- More frequent/granular searching for articles/podcasts.
- Less frequent but more accurate scrolling in a full novel (Improve performance with large a11y trees (entire ebook in one page) #5).
Users may have more context to decide what is appropriate.
My hesitation in making this configurable is that I don't want users to have to deeply understand the inner workings of how this feature works, and I'm not sure how best to make the user experience simple.
When I was using OCR to read Live Captions, I was thinking to use numCaptionLines to determine scroll frequency. My thought was that it may be intuitive for users that "we scroll every time the caption box has been entirely replaced" so if you want to scroll less frequently and consider more caption text (like in an ebook), you can double tap the caption box to expand it.
Another solution might be to have configurable options in Settings > Accessibility > Live Scroll Transcript.
