The usability of real-time feedback in forms

To better understand the usability of inline validation in forms - that is, forms that provide real-time feedback as people fill in answers - Luke Wroblewski set up a usability test comparing different types of form feedback.

Though the participants were confused when simple questions, such as a person's name, were marked "correct", he found that they were faster, more successful, less error-prone, and more satisfied when they used a form with inline validation.

Also, giving feedback after the particpants finished typing - rather than while they were typing - helped the participants complete the forms more quickly.
