Looking for a script that will auto-advance to next field after each word is typed

I have sort of a unique ask:

I was sent a form to add fields to, and on the surface it works fine, but i am trying to streamline the process for the people that need to fill it out. for those in the Ham Radio /Amateur Radio world, this is an ICS 213 message handling form.

For those who have no idea what any of that is, here is an example of the standard form i am trying to modify. https://www.ocraces.org/forms/ICS213%20May%202013.pdf

if you are using a pen this is easy enough to fill out, but most of our uses can be done on a computer, and i am trying to make this as easy as possible. 

The top part of the form, i am fine with "tabing" thorugh the fields, but down in the message body is where i need the help. 

i am wondering if there is a field level script that can be applied where it will auto advance to the next field automaticly when <Space bar> is pressed. 

There are 2 sections i need to apply that to. both of them involve 50 text fields. each field should be 1 word each regardless of the number of characters. The key element is using the space bar to advance to the next field, so someone could right a paragraph without using enter or tab. 

I already have the form setup, i just need to know the script that i can add to each field that would need this function. 

Thank you for any help you can offer
