A good UX for a form is one that makes it easy and fast to use. An experimental form like this, that uses natural language instead of the usual form display seems to be simple to use and creative, but is this enough intuitive?
After I did more research on this UI pattern called “natural language form", a saw this article by Luke Wroblewski, "“Mad Libs” Style Form Increased Conversion by 25-40%". He talks about a “‘Mad Libs’ Style Form” that presented input fields to people as blanks within sentences, in a natural language and publish this conclusion:
Ron and his team ran some A/B testing online that compared a traditional Web form layout with a narrative "Mad Libs" format. In Vast.com's testing, Mad Libs style forms increased conversion across the board by 25-40%.
What do you think about natural language user interface (NLUI) for a form? This innovative design help users to complete the data in a fun, easy way or it is not intuitive and what they expect?
