One of the most famous examples of bad UX design is the so-called Norman Door, named after design guru Don Norman, who first put words to the phenomenon. Picture a door with identical handles on each side. That is a Norman Door. The problem with a Norman Door is that the user has no intuitive idea of how to open it — push, or pull? This is a bad user experience, created by a bad user interface. 

Now picture a door with a handle on one side, and a push plate on the other. Much better! A user looks at that door and knows to pull on the side with the handle, and push on the side with the pull plate. That is what we want from UX design: to make the right choice immediately obvious, so that the user doesn't even have a chance to make the wrong one. I'd like to help you make your site or app just as simple as a door with one handle and one push plate. ​
