I am designing a wizard with 4 steps in it. To make the screens more appealing and easy to click through I converted the radio buttons into big buttons, but they still function like radio buttons in that when you click on a "no" button, then the "yes" button becomes deselected (and visa versa).
Would it be intuitive to progress to the next step automatically when a user clicks on "yes" or "no"?
The complexity comes in on some of the other steps where there are up to three questions with three sets of "yes" and "no" buttons. So in that context the user will not proceed to the next step automatically by clicking on a button, unless they only proceed once they have answered (clicked) on all the required buttons.
My gut says that the "radio buttons" should function consistently throughout the process, but it feels like an effort will be put on the users to have them click on a yes or no button and then on the next button to proceed to the next step when there is only one question with one set of "yes" and "no" buttons.
I'm also thinking about what would happen if the user wants to change their mind on an answer when they have proceeded, which is why there is a back button.
Here is an example of what I am talking about:
