Hi and welcome to Apple Discussions...

iPad: Configuring accessibility features (including VoiceOver and Zoom)
"iPad includes the following accessibility features, which are designed to make it easier for users with visual, auditory, or other physical disabilities to use iPad."
In order to "Zoom" one would need to "double-tap" the screen using three fingers at the same time or to change the Zoom, using three fingers, double-tap and drag up and down.
My experience with this using the pre-installed Notes application is that the Zoom will not increase to an inch in size nor would words be displayed one at a time.
However, for "boredom"... one can enable "VoiceOver". VoiceOver speaks items on the screen by "touching" that item, or double-tapping, or "flicking three fingers" to scroll.
My suggestion to you is to find a friend with an iPad to see if these features will meet the requirements your friend needs. Either that, if you can, visit an Apple store.
