Handwriting practise in Storyline

Is there any clever way to leverage functionality to allow a learner  (5-6 year old) to pratise handwriting? 

I would like to do two things - 

1) Free practice writing letters - here I want Storyline to identify whether or not they have written something (anything) in a particular area to use as trigger for allowing 'continue'

2) Practise correct formation of letters where I want to insert the outlines of one letter per slide and the learner writes between lines/along a dotted line. Here ideally Storyline should give a correct/incorrect response (BUT being able to practise is the most important part. Holy grail would be something that gives immediate feedback if the learner goes outside the lines and a well done if they have written correctly)

Any tips on including ways for learners to write interactively would be most appreciated!

Thanks in advance!
