Designing the User Experience

2

Introduction

If designers do their job properly, visitors won’t even notice how successful the designers were – the design is transparent.

A good web site is designed to work the way people think.

3

Introduction

Two opposing camps in web construction: The Jacob Nielsen usability camp – web

pages should not be pretty, they should be usable.

The “web as an experience” camp – web sites should take advantage of the uniqueness of the medium, stretch the limits of the medium, challenge/engage/ mystify/amuse/enthrall the visitor.

4

Introduction

Both are right, and both are wrong. Most of us don’t have the freedom to

design off-the-wall “experience” sites; we are creating sites for businesses.

On the other hand, there is no reason those sites need to be plain vanilla.

We are going to try to make sites that are both engaging and usable.

5

Introduction

If you create a web site, you are indeed going to be a designer whether you want to be or not. It’s your choice as to how good it is going to look.

Good web sites are:Technically solid User-friendlyAesthetically appealingEasy to maintain (flexible, scaleable)

6

Introduction

This next series of lectures will examine creating a well-designed user interface that is aesthetically appealing.

7

Introduction

Remember, we don’t have complete control over how our web pages display on the visitor’s system:Colors and fonts display differently on different

browsers, on different monitors, and on different systems, because of varying brightness, resolution, and color handling.

WYSIWYG should be WYSINNWYG (“What

You See is Not Necessarily What You Get”).

8

Introduction

Computers are usually shipped configured to a display that is one or more steps down from what that system is actually capable of displaying.• It never even occurs to the majority of users that they

can easily change their display properties.

Commands that work in one browser don’t always work in others.

9

Introduction

These factors make designing a good web page much more difficult than designing a good printed page.As a developer, you probably have the latest and

greatest monitor, graphics card, browser, and plug-ins, as well as lots of RAM and a really fast connection.

Keep in mind that the majority of visitors don’t have all that.

10

Introduction

On the other hand, we have some really cool tools like animation and “free” color that we don’t have on a printed page.

Analysis

12

Analysis Introduction

Why analysis? To avoid the following scenarios…“Hey, you go ahead and start coding while I

go out and ask the users what they want.”The pilot’s “good news bad news” scenario.

13


Don’t just sit down and start writing HTML in order to see progress fast.

You will end up with a poorly-designed site that is difficult to navigate.

Spend the time, effort, and money up front, to avoid disaster later.

14


The first steps of analysis:1. Identify the purpose of your site.

2. Identify your target audience.

3. Analyze the tasks that will be performed on the site.

15

Identify the Purpose of the Site

There are four basic purposes of web sites:

To make money. To disseminate information or

opinions. As a front end for a business

application. To stroke someone’s ego.

16


Purpose 1: to make money.Most web sites fall under this category.The owners of these sites include

corporations, small businesses, dot.coms, and non-profit organizations.

B2B (Business to Business) sites fall under this category.• This is one of the hottest types of online business

today.

17


Visitors’ goals on these sites include:• Researching products.• Purchasing products.• Obtaining service.

18


Principles of making money on the web:• It’s not about art.• It’s not about ego.• It can and should be about information.• It’s mostly about money.

19


Purpose 2: to disseminate information or opinions.Types:

• Corporate intranets, for publishing internal documents.

• Educational institutions, like NIU.• Odds and ends of other sites: e-zines, health and

hobby sites, fan sites, opinion sites (religious, political, and social).

20


Visitor goals:• To obtain information.• To read or express opinions.

21


Principles of disseminating information and opinions on the web:• It’s not usually about art (unless the topic itself is

art).• It may or may not be about ego.

o For instance, a political opinion site may very well be about the ego of the person whose opinions are displayed.

• It’s mostly about information.• It’s generally not about money.

22


Purpose 3: as a front-end for a business application.Intranets, extranets.BUI/Browser User Interface as opposed to

the traditional GUI/Graphic User Interface.Visitor goals:

• To get a job done, with maximum efficiency and speed and minimum training, errors, and hassle.

23


Purpose 4: stroking someone’s ego, perhaps even your own.This includes personal sites, many opinion

sites, and odds and ends of other types.Principles of ego-based sites on the web:

• It can be about art.• It can be about information.• It is always about ego.• It might like to be about money.

24


The purpose of your site determines everything else, including branding: Creating individuality and market value

around the concept of a product or company name.

Associating a mood, theme, ambiance, product category with your company name and product.

25


Examples of effective branding:A Coca-Cola bottle can be recognized

anywhere, even from just one broken piece.

Oreo cookies, Cheerios, Ben and Jerry’s, Godiva, UPS

Bad example: Office Depot versus Office Max. Ideally, visitors would still be able to guess the

name of the site if we removed the name from the pages.

26


Try to find an organizing metaphor (that lends itself well to a visual interpretation) for the site, which makes design easier.United Airlines uses a globe.A hotel might use a check-in desk, concierge

desk, restaurant, etc.

27

Identify the Target Audience

You need to have a precise definition of the target audience, the people you are trying to lure into your site.

If your target audience is college students who are fans of, say, Third Eye Blind, the site should look and function very differently than if the target audience is wealthy executives interested in buying luxury vehicles.

28


Let’s look at some potential audiences for various type of sites…

29


Business site visitorsCurrent customers

• They could be checking product facts, verifying an order, checking shipping on an order, or placing a new order.

30


Potential customers• How did they get to a site?

o From a banner ad or link on another site.o From a search engine.o From printed promotional materials that listed the

URL.

• Might want to have a different entrance page for each arrival method.

• Remember that the whole point is to get someone to open his or her wallet.

31


Investors• Every element of your site should promote the

idea that the company is profitable and stable.• There are legal guidelines about what you can say

to potential investors and how you say it.

Employees• Example: the sales force might use the web site as

a sales tool, or all employees might register vacation days through the web page.

• Intranet visitors might be using secure parts of the site for traditional transaction processing.

32


Non-profit site visitorsActivists and information-seekers

• Give them the information they need to continue to support the cause.

Donors• They need information as well, plus they need to

be convinced that the organization is legitimate and stable and will use donations wisely.

33


Informational site visitorsThese visitors generally fall into two

categories:• Internal visitors• External visitors

34


Internal (intranet) visitors, mostly employees.• There are often serious security issues here.

o Example: A credit card company, where some employees have access to all of a credit card holder’s personal data, while others have access only to name and address or some other subset of data.

• Intranets generally have access to much higher bandwidths that do public websites, so download time is not such a critical issue.

35


External visitors – those accessing a public web site.• The most important factors are organizing the

information (which might be extensive) so that even casual visitors can find what they are seeking and minimizing bandwidth problems.

36


Opinion site visitorsThose accessing the site might support the

opinions presented, might disagree with those opinions, or might be looking for information so that they can form an opinion one way or another.

37


Ego site visitorsThe audience for an ego site is usually its

creator and the more tolerant family and friends of that creator.

If you are building an ego site, you have at least the potential of drawing a larger audience if you make it informational as well.

38


Create visitor profiles, including:Health, age, and gender: implications for font size,

color issues, accessibilityEducation: writing style, complexityLanguage: English only versus alternate versions Income level: who wants to or is able to buy what

you are selling?Computer experience: tutorials, help filesExpectations: theme, behavior, visitor interface

structureUser goals: what do they want to accomplish?

39


You also need to identify the kinds of computer systems your audience will be using to view your site.

You will be making design decisions based upon this knowledge.For instance, bandwidth considerations are less of a

concern if all of your visitors are on high-end systems within a corporate intranet.

They will be a major concern if some of your visitors are on low-speed, dial-up lines.

40

Task Analysis

Identify the tasks the visitors will attempt to complete, the order in which those tasks will be executed, and things that could be done to expedite the entire process.

Called a scenario or use case: a set of possible sequences of interactions between systems and visitors in a particular environment and related to a particular goal.

41

Task Analysis

Can document this in the form of a flow diagram for complex tasks.

Analyze how often and with what frequency they will perform each task.More frequent tasks should take priority.Less frequent tasks need more hand-holding.

42

Task Analysis

What if the user doesn’t complete the task?

What to do if errors?

Information Architecture

Categorizing and structuring informationContent + Context + Usability

45


Well-designed web sites are usually a hierarchy:The home page.The main topic pages, just under the home

page.The subsidiary pages – any page under a

main topic page or another subsidiary page.

48


Some WYSIWYG editors (like Dreamweaver) let you create a hierarchy chart with drag-and-drop, and you can even name the pages as you do it so that it creates a skeleton HTML file for each page.

49


You must decide: What should go on the home page.What should go on the main topic pages

under the home page.What should go on subsidiary pages under

the main topic pages.The navigational aids needed to get from one

area to another.

50


The home page should give an overview of the navigation of the entire site.

You can view the home page as the equivalent to the cover or table of contents of a magazine; if viewers don’t see anything of interest, they won’t browse any further.

51


The home page should convey:The purpose of the site – the who, what,

where, and why.The content buried within the site.How to find that content.

If it isn’t important, it shouldn’t be on your home page.

52


Each main topic page under the home page should convey what lies underneath.

Subsidiary pages show the actual content.

53


Organizational possibilities:By importance or frequency: the most

important or frequent items first. • On country codes, US sites list USA first.

By users: employees, clients, investors.By topic: products, services, contact

information.By task: order product, get technical specs,

contact us.By department: Sales, Human Resources,

Manufacturing.

54

Information ArchitectureBy product categories: desktop systems,

laptop systems, accessories.By alphabet: only if the visitor knows the

name of what he or she is looking for.By geography, chronology, metaphor:

obviously, when appropriate.

But be careful: bad examples include professional versus amateur (photo site) and business versus home (Epson printers).

55


Hybrid sites use a combination of schemes.Can be difficult for visitors to form a mental

model of the site. Easier if grouped in separate menus.

56


Hierarchies can be broad and shallow,

• Or narrow and deep.

57


Although traditional user interface design rules called for a maximum of seven choices on a menu, web usability studies are showing that visitors prefer broad and shallow systems instead.Visitors want to avoid downloading any

excess pages. Smaller top-level menu choices can end up

requiring vague wording, which hides what the visitor needs.

58


Large, complex sites might make use of multi-level menus; drop down or pop up sub-menus on click or mouseover of a top-level menu item.

59


Organizing the site files:Typically separate folders for at least images,

original images (native PNG and PSD files), CSS, JavaScript.

Name all files relatively, then you can port the entire site unchanged to the server when it is done.

Name files by function, not by a style attribute.• Good: add_button, go_back_button• Bad: blue_button, 3_d_button

60

Creating a Web Site with Appeal

Appeal means that visitors enjoy and become engaged in site.

The buzzword these days: experience design. Draw the users in, engage them.

Think of a restaurant in which the food and the décor and the service are all a part of the experience, like Olive Garden.

Or a store like IKEA or Illuminations (again, branding).

61


Five attributes of a web site with appeal:It should look good and be appropriately designed

for its purpose and its audience.• Professional, or fun, or cutting edge, or…

The experience must be unique to the medium.It should, if possible, evoke emotion.It must be functional: easy to use and navigate.It must be marketed properly.

62


For any site, the designer should use restraint.

For instance, gratuitous animation increases download time, perhaps so much so that people who might stick around to make a purchase instead leave the site, defeating the site’s purpose.

63


Keep a “tickler file” of ideas: color combinations, layout ideas, whatever, from magazines, books, articles, and other websites.

Check out the competing web sites, then either be somewhat similar yet distinguishable, or radically different.Branding is key.

64


Study from Stanford University’s Pervasive Technology Lab, quoting B.J. Fogg, the director (http://e.register.com/a/tBActeKAEIqG3AQB7DgAHnEeZ9F/opt4) …

65


“The number one factor by which people actually judge Web site credibility was by their first impression of the visual design… if it doesn’t look credible or it doesn’t look like what they expect it to be, they go elsewhere. It doesn’t get a second test. And it’s not so different from other things in life. It’s the way we judge automobiles and politicians.”

66

For this class…

Everything must fit on an 800 wide window, with no horizontal scrolling. Vertical scrolling is ok. We’ll look at why in a lecture or two.

But you don’t have to stick to websafe colors – more on that later.
