interactive books are now a craze on online gamification portals like Xperiencify...

so can anyone take that in consideration ??

Yes. There are other competitors out there who have a wide variety of interactive elements that would be huge for this. Some are just clickable hotspots that create a pop up with additional information or additional media. This should be the first step as it is still all "consumer" based and the reader isn't required to give any feedback. It just makes the reader's experience richer. After that, adding responsive features like quizzing, polling, multiple choice testing, and other educational features would make this product very desireable in that field.

I would love that. I'm building a workbook also. Currently, the user will need to download/print it.

Maybe not just text boxes but different types of interactive elements, for example, checkboxes, multiple choice/multiple answer questions, pairing, etc. This way teachers can create a hybrid textbook/workbook.

wow that would be awesome but I think a hard task?

That would be gooy
