Hi there, is there any idea for getting the text under the mouse cursor?

I'm trying to build a dictionary app, that pops up a panel of translates when mouse hangs over a word.

I took a look at the accessiblity apis, and it only can find the current ui element, but not the current word...

my last choice will be makeing screenshots frequently, and doing ocr... that'll be cpu consuming, I don't like that..

any idea for this? thanks in advance!
