Taking the mystery out of User-Centered Design

Rapid Prototyping: Slideshows

on 17 April, 2008

First of all, let me express to you how important rapid prototyping is.

You absolutely ought to do requirements gathering first, then come up with a theory of what your users want, then build a quick-and-dirty prototype and take it back to users – both the ones you gathered requirements with, and others. This can take you a few days and cost a few hundred dollars, and it can save you hundreds of thousands in development, materials, or man hours.

So now that we’ve established that you all agree and will employ rapid prototyping before you build anything big, let’s get into the meat. There are a lot of ways to do make a prototype. Depending on your medium, you can build a cork-board model, draw pictures on a piece of paper, or whip out wireframes and screenshots. Regardless, you shouldn’t spend too much time on them – depending on the size of the project, we’re talking an hour to 2 days, no more. They don’t have to be perfect, fancy, interactive, or anything along those lines. They are nothing more than a tangible representation of an idea or concept. Nothing more.

One way, particularly useful for an experience (like a tour), or an application (web-based or desktop) is to use a slideshow.

Irfanview is a free, easy to use downloadable application. It has lots of features, but the only one I ever use is the slideshow builder. You can drag screenshots in, and then set controls on each for mouse click, arrow, etc. This enables you to get on the phone with a remote user, and bring up the screenshots in any order you want, without opening gifs from a folder. It can completely fake user interaction, as far as clicking goes – click with the mouse and it can take you to a next screenshot that shows a list expanded or a field filled in.

It saves out to an .exe file, so you can then send the “prototype” to anyone you want. You can make it go from slide to slide automatically, or control each slide individually. File sizes are reasonable. I also use it for training, and believe it or not – I have a version of my portfolio in an executable slideshow. Many possibilities for a little free gem!

Irfanview’s interface isn’t the prettiest or simplest, but the basic functionality only took me a few minutes to figure out. It’s incredibly powerful, when you’ve got a test you need to keep running smoothly.

Enjoy this tool, and if you find others like it, please comment and let everyone know!


Today’s Glossary Term:
AEIOU – A research method focused on Actions, Environments, Interactions, Objects, and Users. It’s primarily used for ethnography (studying people and making a mental model of how they see the world) but can also be a good mnemonic to spread throughout your team. It helps to get everyone thinking of the world from the user’s point of view.

Today’s Interesting Link:
http://www.csszengarden.com/ – Is one of the places I go when I’m feeling boxed in by a design. It’s a great resource for inspiration, or if you’re looking to improve your CSS skills. If you don’t already have Zen Garden bookmarked, you really ought to.

Today’s Usability Quote:
“The greater danger for most of us is not that
our aim is too high and we miss it, but
that it is too low and we reach it.”
– Michelangelo

Today’s Music To Design To:
Getting away from the edgy electronica, it’s time for a Jazz recommendation. However, Jenna Mammina is not “just” jazz. She uses her voice like an instrument, switching between belted lyrics and then lilting back into a soft, sultry croon.
