DESIGNING INTERFACE

“Like putting an Armani suit on Attila the Hun, interface design only tells how to dress up an existing behavior.” – Alan Cooper

TRANSFORM YOUR FLOWSMaking pages out of boxes and arrows

A task analysis

From Information Architecture: Blueprints for the Web, this is a task analysis for a website for Sundance film festival, featuring a schedule

planner

Each task could have a page

1995: first graphic logo

Remind you of something?

Including the schedule creator tool…

Wizards: Many boxes,many pages

Use Wizards:

‣ When users want to accomplish a goal that has many steps. Wizards are good at making sure you don’t miss a step.

‣ When the steps must be completed in order. Wizards are linear, so it’s impossible to complete them any other way.

‣ When the task is seldom performed. Wizards can seem slow and plodding, so they are best used in tasks you do only once in a while, like setting up a printer.

‣ The audience is not technically savvy and is likely to be confused by a page with a lot of choices on it. A Web site can have novice users, and a wizard makes complex tasks seem easy.

‣ Bandwidth is low and downloading a single big page could take forever, or the tasks require several server calls, which would also slow the page’s load.

‣ The task has several steps in it, performed only once a visit, such as checkout.

On the web, they are often account settings

TOOLBARSBring the settings and the thing modified together

What if we put the tasks with the thing they were modifying?

It’s a toolbar

Toolbars

Tools here Item affected here

And here

Photoshop: toolbars on steroids

The web uses toolbars more sparingly

A simpler design is better for

infrequent use.

DRAW A PLACE SETTING – 30 SECONDS

Fork, spoon, knife

An Interface is like a table setting, the tools you need are next to the food you eat. Content is the meal.

Two videos sites.The “meal” is the video, and the tools to consume (or play with) it

are arrayed around the main meal.

(P.S. There are toolbars too)

Why is the response so far from the invitation?

ARTICLE OF CLOTHING:WHAT TOOLS WHERE?

Task

ZONE YOUR PAGE

When designing the page, group items by similarity and similarity of task (navigation items together, editing items together)

Give them visual importance based on user number, usage frequency and importance to business.

‣ Create “zones” for functionality groups.

‣ You can group them by putting white space around them, or use lines

‣ Remember to keep tools close to the thing your working on

ZONE YOUR HOMEPAGE

HOW TO MAKE A WIREFRAME IN 30 SECONDS

Draw a rectangle

Add global elements

‣ Next, add the key zones

‣ Start with a list of elements, perhaps written on post its. Group them, then find them homes on your page.

‣ The fill in the actual elements

FINALLY, ANNOTATE

Consider

‣ Where does the content come from? If you have a list of related articles, specify how they’re related. Are they the most viewed? Most viewed from that section?

‣ What is the nature of the content? Does it vary greatly in length, size, language, and type?

‣ Is the element required or optional? What happens if the element doesn’t appear on that page? Does the layout change?

‣ Is the element conditional? Does it vary based on other factors? For example, do administrators see additional links? What happens if an article doesn’t have an associated image? What if it does?

‣ What’s the default or expected state? Ideally, what’s supposed to happen on the page.

‣ What are the alternate or error states? How does the design change when things don’t go right?

ON SUBTLETY

When you don’t want to interrupt an action, be subtle (think of footnotes). If they are reading, don’t bother them.

When you need to prompt an action, subtlety will send you to the poor house.Tell your users what to do. Clarity is relaxing, not annoying.

ACTIVITY: DESIGN YOUR SIGNUP FORM

15 MIN.

1. Individually design a sign-up form for your project.

2. Think about the following element:

1. Name (first/last?)

2. Username/nickname?

3. Password (enter twice?)

4. Terms of Service (link/display?)

5. Sign up with Facebook/Twitter?

6. Optional demographics?

7. Over 13?

Navigation: IA made visible“Like putting an Armani suit on Attila the Hun, interface design only tells how to dress up an existing behavior.” – Alan Cooper

Most IA is invisible

A lot of work no one sees‣Synonym rings‣Controlled vocabulary

If it was seen, it would be too much to understandWe show only a part via navigation

“After testing several different sitemap designs on users, I decided to try putting one on every page of my small Columbian web site. I then decided to track how often it was used for navigation. It turns out the sitemap is used for over 65% of all navigation done on the site.” -- Usability Report by Peter Van Dijck of poorbuthappy.com (Guide to Columbia)http://www.webword.com/reports/sitemap.html

It is certainly probable, then, that placing these objects in expected locations would give an e-commerce site a competitive edge over those that do not…

ConventionsIf 90% or more of the big sites do things in a single way, then this is the de-facto standard and you have to comply. Only deviate from a design standard if your alternative design has at least 100% higher measured usability.

If 60-90% of the big sites do things in a single way, then this is a strong convention and you should comply unless your alternative design has at least 50% higher measured usability.

If less than 60% of the big sites do things in a single way, then there are no dominant conventions yet and you are free to design in an alternative way.
