UPA 2002 – Humanizing Design

by:   |  Posted on

The Usability Professionals Association (UPA) 2002 Annual Conference was held For local chapter members, the UPA national conference is a way to tap into the national organization, yet for anyone who is practicing usability the conference provides ample information, education, and networking opportunities.July 8-12 in Orlando, Florida. Almost 500 attendees from around the world flocked to the Hyatt Regency Grand Cypress Resort – a tropical resort hotel just beyond the reaches of many Disney theme parks. The conference differs from others like CHI -in that it tends to focus almost solely on topics for usability practitioners. We’ve heard some practitioners say that CHI is too academic – too focused on academics and primary research that may not be clearly applicable yet to those designing and evaluating products. At the UPA conference you generally don’t find academic research presentations but rather case studies and lessons learned in the school of hard knocks.-

Three attendees from the UPA-MN chapter in the Minneapolis-St. Paul, Minnesota area, Katie Ware, Lyle Kantrovich and Debbie McConnell, cover some of the sessions they found most notable during the 5-day conference.

Keynote: The Domestication of Computers
Joel Birnbaum, Sr. VP of Research & Development, Hewlett-Packard
Reported by Lyle Kantrovich

Birnbaum’s keynote presentation started off the conference by detailing a possible future when computers are much more invisible and pervasive. The premise is that, as we “domesticate” computers they become more ubiquitous, much as electric motors have become things we don’t really think about – they are embedded in products and services that we use without thinking about the motors themselves.

Before computers can become pervasive, they have to deliver value and exhibit good usability. Pervasiveness also has to be built from good infrastructure and enduring standards with security and reliability built in. Pervasive computing will most likely be packaged in “information appliances” that will hide the complexity of computers to deliver ease of use, be context aware, and in many cases be mobile.

To illustrate what a powerful change pervasive computing might deliver, Birnbaum showed videos of different future scenarios. The longest video showed an earthquake emergency in which emergency services like police and fire departments were able to assess damage to buildings, collect data from field observers about injuries and properly respond by routing the necessary services to the most urgent needs. The video included examples of self-healing communication networks, handheld language translators and sensors that automatically collect data from buildings and many other information sources.

Birnbaum’s presentation was interesting and timely, especially for usability practitioners who’ve spent the last year trying to side-step layoffs and a slow tech economy. It provided hope that the future might offer more opportunities for user-centered design. Designing for pervasive computing’s information appliances might also bring more diverse opportunities for those who’ve tired of working on all things web. The crowd seem to think Birnbaum’s videos were a bit futuristic – a little too Star Trek if you will – they laughed when the earthquake-damaged network flashed an on-screen alert informing the user that it was repairing damaged lines. According to Birnbaum, most of the technology in the videos has been available for some time – the biggest obstacles to pervasive computing are interoperability standards and adoption.

Although Birnbaum’s future of pervasive computing may be decades away, it was clear that the role of usability professionals would be critical in making such a future a reality. Then again, when you look at the latest models of automobiles just hitting the market – vehicles that haves sensors to warn you before you back into something, that remember your personal seat and mirror preferences, and that can make calling for roadside assistance a one-button event – pervasive computing might be just around the corner.

Promoting yourself and usability (which comes first?)
Ilise Benun, author of Self Promotion Online
Reported by Lyle Kantrovich

You might think that promoting yourself is something that only self-interested egotistical people do. After attending this session it was clear that “self promotion” for usability professionals is really customer-centric and involves simply communicating the value of what we do.

Ilise Benun’s main point was that promoting usability is fundamentally about promoting your skills and value as a usability professional. We have to understand the people who use our services, we have to talk to them in their own language, and we have to make our deliverables usable. Think of it as “sales the UCD way.”

We often struggle with how to “sell usability” yet we don’t want to appear pushy. Benun pointed out a simple opportunity for self-promotion that we run into all the time: people ask, “What do you do?” She pointed out that it helps to have a short “blurb” that describes what we do. The blurb should make people want to learn more. We can then expand on our short blurb to explain who we do “it” for and how or when we do “it.” The explanation should avoid jargon and titles like “usability engineer”, “experience design” and even “usability.”

By simply educating others about what we do, and the value it provides, we promote ourselves. If usability delivers cost-savings, we become valued cost-savers. If usability increases customer satisfaction, we become people who can deliver and evaluate satisfying products.

Benun pointed out a number of ways to become valued and promote yourself (and your services):

  • Reach out to others (don’t wait for them to come to you)
  • Give out your ideas, information, and your business card
  • Create helpful documents
  • Answer questions on discussion lists
  • Emphasize the positive (don’t just be a critic)
  • Be professional, reliable, and responsive

Any conversation with a potential client is an opportunity to a) learn something about them b) offer something useful to them c) show your interest in what they do or have to say d) link what you do to what they do and e) exchange contact information.

Not only did Benun deliver convincing reasons to feel good about self-promotion, but she also outlined simple steps anyone can take to better promote the business value of usability.

During the Q & A session, an attendee from a major software company provided an example of how good promotion of usability can pay off: They convinced a vice-president to sponsor the cause of usability at their company and it paid off big time – their CEO now has a “usability scorecard”, and all their products have to be on it.

Usability and ROI
Reported by Katie Ware

What is the focus when attempting to improve the bottom line – cost savings or increased revenue?In this economy, the bottom line is what matters. What is this going to cost and what benefit is the company going to get from it? This issue was reflected in the SIG entitled “Validating Design Decisions and Establishing ROI by Exploiting Existing Data Sources within Your Organization” and a presentation on “Measuring the Return on Investment for Usability.”

The SIG was a place to ask questions and express frustrations, but there were more questions than answers – it became clear that there is no silver bullet. There were many different types of companies represented, and although this provided diversity, it sometimes made it difficult to transfer ideas between different business models. For example, return on investment (ROI) techniques from a company that is strictly e-commerce may not be easily implemented in a situation where there are multiple distribution channels. There may be more work required to include measures to track feedback by channel.

Planning, benchmarking and tracking were major themes – laying the groundwork for justification is key. Some suggestions from the SIG:

  • Look at call logs – quantitative sample with a qualitative look, coded by type of issue
  • Maybe total calls don’t go down significantly, but shows in other ways (such as fewer UI calls)
  • Likert scales at the end of usability testing “measures” perceived value point

It was a lively discussion – and although the group was diverse, we were all looking for answers. It’s obvious that this is a big issue and once the exchange started it was hard to stop. In fact, the moderator had to leave for another meeting before the conversation wound down.

The “Measuring ROI for Usability” session consisted of a panel that included Randolph Bias – Austin Usability, Kelly Braun – EBay, Joe Bugental – Sun Microsystems, Inc. and Ed See – Arthur Anderson/KPMG. Stephanie Rosenbaum of Tec-Ed, Inc., moderated the panel.

The panelists presented case studies of how they have tracked usability ROI. Randolph Bias and Ed See offered insight about usability ROI from the consultant point of view. Joe Bugental spoke about Sun Microsystems iterative usability program that measures usability ROI for a widely used defect management software. Kelly Braun presented information on how eBay uses ROI estimates to determine the level of usability coverage a project will receive during development.

The main topics about the benefits of usability ROI focused on factors that play into the bottom line. These were:

  • Increased product development efficiencies
  • Decreased burden of customer service and tech support calls
  • Reduced training costs
  • Increased sales
  • Increased user productivity
  • Increased customer satisfaction

Again, planning and benchmarking are crucial for tracking. How a company approaches them, however, may require some creativity.

What is the focus when attempting to improve the bottom line – cost savings or increased revenue? Both are important and finding ways of addressing both can provide for flexibility in planning. Some ways to calculate ROI are cost of diversion in missing revenue opportunities, the cost of answering users’ questions and the cost of training. How long it takes for benefits to surpass costs is a formula that can be used to calculate ROI in raw dollars.

Another issue is to whom the benefits of ROI accrue. The development team may assume the cost of a change, but customer service reaps the benefits. And how will the director of training take the news if increased usability means that not as much training is needed?

There is no one size fits all for ROI. One message that came through is that we need to speak the language of the audience – the stakeholder to whom the cost/benefits apply.

Handheld Usability
Scott Weiss, author of Handheld Usability (John Wiley & Sons) and principal of the Usable Products Company
Reported by Debbie McConnell

The one-day tutorial on designing interface for handheld devices, called “Handheld Usability: Designing, Prototyping, and Usability Testing Applications for Pagers, PDAs, and Mobile Phones,” was just as jam packed with information as its fourteen word title implies!

As expected, we learned how designing for handheld devices is different from designing for desktop, laptop, or even palmtop PCs. In addition, there were surprising differences between designing for cell phones and designing for Pocket PCs or other PDAs. In the process, we learned lots of new terms like soft key and triple tap.

Each handheld platform has its own set of user interface controls and related guidelines. For example, designing for Wireless Application Protocol (WAP) used by many cell phones means employing lots of short text menus organized in a limited hierarchy with good cross links.

Designing for PDAs is very different. These devices have much richer data input and GUI mechanisms. Their user interfaces include familiar features, such as application menus and dialog boxes. However, these features need to be implemented with regard to the PDA. For example, the application menus should not be cascading like the ones that are commonly found in desktop interfaces.

Most handheld interfaces employ some type of graphics, including icons. Many of the standard design rules apply, such as avoiding 3D and using distinct shapes. There are also some guidelines that are unique to handheld devices. For example, it is important to test these interfaces by taking the device outside. It’s the most challenging environment for creating high contrast and it’s also the most common environment for “on the go” devices.

The most interesting part of this experience was the chance to explore the rationale behind these devices – the social and professional drivers that cause people to learn cryptic interfaces and use these relatively cumbersome devices.

Modeling Design
Richard Fulcher, Bryce Glass, and Matt Leacock, of America Online
Reported by Debbie McConnell

The 90-minute session, on UI design, using concepts maps, wireframes, storyboards, and flow maps was perfectly timed for me. I am currently struggling through the design of an e-commerce site with a client that has been unable to describe the scope of the site. Not just the first, second, and other phases of development. But, even more fundamental issues like “What is the purpose of the site?” and “How does is fit within the parent site?”

I’ve been using diagrams to represent workflows, individual task analysis, and site maps for years. However, somewhere along the way, I stopped taking the time to create detailed concept maps to help establish a shared image of the final product before I went on to describe how the interface should be represented.

Since attending this session, I have returned to work on the e-commerce site and created a concept model that is helping the entire team define the project’s scope and objectives for success. My experience fits well with the title of this session, “Boxes and Lines over Bullets and Arrows: Deliverables that Clarify, Focus, and Improve Design. ”

You can view a copy of this presentation and the related deliverables at http://www.leacock.com/deliverables.

Overall, the 2002 event was a good one – providing solid presentations and an informal atmosphere for meeting and talking with other usability professionals. We found favorite authors and gurus in the sessions, hallways, and commons, and most were very willing to chat and answer questions.

The UPA conference also provides opportunities to get involved in a thriving professional organization – local UPA chapters started forming about three years ago and continue to pop up around the globe. Members of different chapters got a chance to meet and share the stories and successes of their individual local organizations. Some chapters are just forming, some had conducted joint events with other associations like SIG-CHI and STC, one had even planned their own local mini-conference.

For local chapter members, the UPA national conference is a way to tap into the national organization, yet for anyone who is practicing usability the conference provides ample information, education, and networking opportunities. Many attendees seemed to have at least one or two notable discoveries to talk about – gleanings they were leaving with and would put into practice on their next design, evaluation or consulting gig.

CHI 2002 – Changing the World, Changing Ourselves

CHI 2002 Summary
Minneapolis, Minnesota—April 20-25, 2002

CHI, the annual conference for ACM’s special interest group on computer-human interaction (SIGCHI) was, as usual, packed with information, research findings, and hotly debated theories. In this article I’ll try to cover the events and topics that were most interesting to me as well as the issues that stirred up the most intense conversations during breaks or at social gatherings afterwards.

Tutorial and workshops
The first few days of the conference schedule were dedicated to tutorials that allow attendees to hone their skills, and workshops where participants share ideas and experience related to specific topics. I attended a couple of excellent tutorials: one by Deborah Mayhew on how to establish a usability organization and another by Rolf Molich on advanced usability testing. I also went to User Interface Engineering’s Monday night tutorial that covered their latest research findings.

Experience Design Forum
The CHI2002/AIGA Experience Design Forum was a new joint event that ran concurrently with the tutorials and workshops on Sunday and Monday. Since I was attending tutorials on those days, I didn’t get a chance to experience this rather groundbreaking event that brought the design and usability communities together. It was rather cool to see folks like Clement Mok, someone I wouldn’t expect to see at CHI, mingling at the Sunday night networking reception. Everyone I talked to indicated that the ED Forum was a pretty good experience and that they hoped it would continue to evolve in the future.

Plenary: David Brin (or “I’ll show you mine if you show me yours”)
David Brin is a science-fiction author whose novels include Earth, The Postman, Startide Rising and Uplift War. The Postman was made into a movie in 1998 with Kevin Costner.

Brin has a doctorate in astrophysics and considers himself a “futurist.” The subject of his talk was based on his non-fiction book—The Transparent Society: Will Technology Make Us Choose Between Freedom and Privacy? Brin’s position was that, rather than seeking greater privacy, as a society or culture we should seek greater transparency to ensure the preservation of freedom and safety.

Brin’s theory is that in order to avoid an Orwellian “Big Brother” type of future where a select few “watchers” have information on everyone else, it’s better that everyone can watch everyone else. With new technologies like tiny surveillance cameras, no one can expect to keep everything private, and transparency is the only workable solution. He did say that there would need to be limits on the kinds of information that is publicly available and drew the line at things like medical history. As you can imagine, such a controversial idea really got people talking.

Another major point in Brin’s talk was that the human race must rely on criticism in order to avoid major pitfalls in the future. He feels that criticism, sometimes in the form of fiction, helps to prevent misuse of science and technology. Brin said films like Dr. Strangelove and On The Beach helped us see the dangers of nuclear war. Likewise, he thought Orwell’s 1984 has helped prevent a Big Brother society. People definitely took up Brin’s banner of criticism as they moved into the technical sessions, freely taking issue with speakers and panel members when differences of opinions came up.

The theme of the conference was “Changing the world, changing ourselves.” I’m usually not one for “themes”, but I think Brin’s opening helped attendees think about how we might change the world and ourselves.

Panel: CHI @ 20 (or “Clean cars, white rats and people”)
The purpose of the first panel was to discuss the past and future of HCI, usability and related fields (I’ll refer to it as “the usability field”). Mitch Waldrop, biographer of JCR Licklider, gave a brief history on Licklider who was an early pioneer in personal computing and cognitive psychology. Licklider started or greatly influenced many early computing companies and labs like BBN, ARPA, and Xerox PARC.

Donald Norman said that we can’t just be critics, but need to become designers and think more about aesthetics.Donald Norman talked about what he considered to be some of the best HCI labs: IBM, Microsoft, and Apple (“until Jobs fired their group”). Norman then asserted that usability is “still marginalized,” and needs to work more with industrial designers. He said that we can’t just be critics, but need to become designers and think more about aesthetics. To illustrate how aesthetics affects user satisfaction, he said, “clean cars drive better.” According to Norman, we need better design tools, but we also need to become better business people and help the marketing side of our companies.

Stu Card said he thought HCI has been a major success, but that we’re backsliding. He also said we need to build things and start by establishing “good foundations”—I took this to mean a strong basis of research that is well accepted. Marilyn Tremaine said HCI needs to change its attitude. She said current HCI courses focus too much on new techniques, and that students often don’t know how to apply the concepts they learn to new situations. She also seemed to be calling for a renewed focus on basic concepts and fundamental research, outlining these five things she thinks we need to do:

  • To reward replication
  • Frameworks for designers
  • A set of “white rats”
  • Theory of evaluation methods
  • To stop being cool

Ben Shneiderman said SIGCHI needs to be more in the public eye like other computing disciplines. We need to work more closely with the press, government officials and policy-makers as well as the public. He echoed Norman in saying that we need to move out of the role of critic.

Don Norman poked a few barbs at ACM (SIGCHI’s parent organization), saying it shouldn’t be the “Association for Computing Machinery”—it’s not about machines, but rather, about people, he said. He pointed out that people don’t really care about interfaces, but about what they can do.

Norman also noted the constant struggle for a better title saying, “we tried interaction design, but now that means ‘hey my web site flashes’.” He said that, in reality design is done by teams, and no one person needs to cover both the “quantitative and aesthetic” aspects.

Card pointed out that some of the best systems designed in the past came from an environment where the people that led design ran the whole project. He noted that whoever gets to the design step first in a product development cycle has the most power. For instance, in jet design, the fuselage design is usually done first based on airfoil work, and that will usually preclude any changes to the fuselage design based on the need for more space inside the cockpit.

The general theme across the panel was that usability, as a field, needs to focus on its visibility, adding value to business by better integrating with the design process, and really proving our theories.

Panel: Formative Evaluations (or “What’s wrong with usability testing today?”)
A formative evaluation is an assessment of a product while it is being developed. In contrast, a summative evaluation is one that is conducted at the end of a product’s development cycle. This panel focused on usability testing as a type of formative evaluation.

You’ll note that the panel was pretty hard on usability testing as a method, but they didn’t seem to have any magical better solutions either. This was one of my favorite sessions since it really made me think about how to improve the usability tests I conduct.

Joe Dumas talked about early usability tests he conducted while working with the U.S. Air Force early in his career. The tests took 6-12 months, and he spent a lot of time justifying and explaining the method. Because the tests took so long to conduct, they ran into issues getting test results used. Joe pointed out that “iteration is a mantra often spoken, (yet) seldom followed.” His point was that in order to really affect the design, usability tests have to be conducted in a quick and timely manner.

Jared Spool said that when they first started doing usability tests at Digital, they didn’t know what they were doing and made a lot of mistakes. He said “now, we think we know what we’re doing,” but he said, we have no documented cases showing that usability tests make a difference from a business standpoint. I found this a bit ironic, since Spool’s firm (UIE) sells research reports largely based on usability testing they conduct.

Bob Bailey said he started doing usability testing in 1970, and that tests are still run in the same basic fashion. He said that, during usability tests, we collect a lot of preference data and incorrectly draw performance conclusions from it. He also said that testing turns up a lot of false positives—that up to 50 percent of “problems” found during testing really aren’t usability problems.

Rolf Molich pointed out that the hardest part of usability testing is communicating the results to the design/development team that can make the proper design change. He said that reports alone don’t do any good, but that we have to build consensus within the project team.

Spool said that, from a practical standpoint, there is no “summative evaluation” because there is no “end of cycle.” Jared joked that “end of cycle is when the dot com finally closes its doors.” Otherwise, product design typically iterates—therefore post-implementation evaluations can be used to inform the next release. He said that, in UIE’s research, the products that were the most usable were delivered by teams that think in terms of three or four releases, not just one release.

Audience questions at large sessions at CHI 2002 were submitted on index cards and the session moderators selected what questions to ask the panel members.

In response to an audience question about automated test tools, the panel had much more optimistic outlook than I expected. Dumas said that most automated tools gather data at too low of a level and the data can be very messy to deal with. He thought it would contain more preference data than performance data (though most of the vendors I talked to said just the opposite). He mentioned that there’s a study soon to be published that looked at remote testing versus lab testing. Bailey cautioned that automated tools might move us toward a more experimental process, and that might present the issue of finding too many “problems” that don’t really make a difference.

Rolf Molich was hesitant to offer opinions on automated tools. He said “let’s go test them.” This was one of the themes I heard Rolf repeat many times during the conference—basically that we need to quit offering and following opinions and go prove something true, false, better, worse, or whatever. Rolf said that automated tools might be a kind of better mousetrap, but we need independent tests, not vendor sponsored tests, to prove whether automated tools are really better than traditional usability testing.

Bailey said one benefit of automated tools is that they allow us to work with a much larger sample size for a given test. He also said we still haven’t validated many of our other methods. Spool jumped on this point and provided an analogy: In the 1850’s doctors used leeches as treatment for a broken leg—they didn’t set broken legs. According to Spool, we don’t know if the methods we have today are “leeching or leg-setting practices.”

Molich then echoed something I’d heard Deborah Mayhew say in her tutorial. He said we should use usability testing for what it’s good for: showing developers what a real usability problem is. We need to move teams toward taking preventative measures, like following heuristics, rather than simply evaluating after the fact, he said.

After providing some healthy introspection on the topic of usability testing, the panel was asked to provide a few comments on the future of usability testing and any positives they see ahead.

Bailey commented that he thinks Molich’s CUE studies are excellent (I have to agree). These studies compare test finding of multiple teams testing the same web sites. The results of the studies clearly point out some areas that anyone conducting tests should focus on as well as some common pitfalls.

Bailey also said “people need to understand how hard usability really is.” Echoing Molich, he added, “We’ve been saying we know the answers, and we don’t know the answers, but we’re turning the corner.”

Dumas summed up much of the conference, saying, “we’re in a questioning phase, and we need that.” Bailey said that the goal of experiments, usability testing and engineering is “to seek the truth.” It seemed as though that’s what the panel was asking everyone in the usability field to do: to seek the truth—in research, in practice and in each other.

Molich noted that practitioners need usable research from research organizations. Bailey pointed to Spool’s UIE and the Software Usability Research Lab (SURL) at Wichita State University as two groups that are putting out usable research. But, he said we need further research to validate and confirm research findings.

PARC—Still cool after all these years
At one of the papers presentations I attended, PARC was showing off an experimental browser it developed called “Popout Prism.” Popout Prism provides an enhanced document overview alongside the web page that the user if browsing.

Essentially, it looks like a thumbnail of the whole web page (not just the visible part) in a window pane to the left side of the browser window. The user can scroll quickly by clicking anywhere on the thumbnail image.

What really makes Prism “pop” though is the popout concept it employs. The user can enter specific keywords they’re looking for, and Prism creates large colorful boxes with the keywords in them (“popouts”) wherever those keywords exist in the web page. The popouts are shown in both the browser window and in the thumbnail. They disappear after a few seconds in the main browser so that they don’t obscure the view of content – but they reappear whenever the user scrolls again so the user can find the information they were looking for.

Prism is very slick. You can download it yourself and play with it. It doesn’t have all the features of a standard browser, but I can definitely see this type of interface integrated into browsers, and possibly other software like email packages.

Certification anyone?
Certification of usability professionals was a hot topic at CHI this year. A Special Interest Group (SIG) was held on the topic, and there was some talk about Human Factors International’s certification program they were promoting in the weeks right before the conference. At my local Usability Professionals Association-Minnesota chapter meeting, which was held at CHI, Julie Nowicki, Chair of the UPA Professional Development Committee, talked about her involvement in an international consortium on certification for usability practitioners. The consortium is currently evaluating the feasibility of such certification. The proposed certification would cover user-centered design as described in ISO 13407.

I didn’t get a lot of details, because I had to leave early, but it sounds like this will be in the works for some time. It will also be presented at the national UPA conference in July.

Ask Jakob
Jakob Nielsen, affectionately called “the Great Dane” by some, was invited to answer questions from CHI attendees, and Nielsen provided some rather spirited answers. I’ll try to summarize some key points rather than go through the whole Q&A blow-by-blow.

On usability testing with just five users:

  • It’s usually aiming for insight for design impact, not statistical accuracy, so you don’t need lots of users.
  • Experienced usability professionals can assess how severe a problem is and don’t need to see the same problem with 100 users.
  • Coverage is always an issue. You won’t cover 100,000 pages with 20 users. Need to focus on high-level things like navigation and style of content.
  • You’re better off studying more things rather than more users.

On web application vs. web pages:

  • With applications, user typically selects a particular application as the one they want to use. For example, a particular game, extranet, etc. With web pages, often there are lots of other pages available.
  • Tasks are different—you run into problems if you treat applications the same as web pages (from a design standpoint).
  • It doesn’t make sense to convert all legacy applications to web applications. Whenever he hears that a company wants to covert existing applications (e.g. a call center) to web applications he thinks, “There goes a million dollars of productivity.”

On new ethical questions in usability:

  • Sometimes have to be careful what you report publicly, so it isn’t used against users/consumers. For example a 1996 study showed users clicked ads that looked like error dialog boxes—but it wasn’t reported then to avoid promoting bad advertising practices.
  • Nielsen showed a clip of an interview he did with CNN Headline News where he was warning parents that kids are very likely to click on ads, thinking they are content. He pointed out that a lengthy report had to be boiled down to a very simplified message.

On aesthetics:

  • Good interaction design is a combination of science and art.
  • We need to get business to understand the art part of it.
  • The need for aesthetics is easier to communicate by example.
  • Aesthetics and usability aren’t inherently in conflict, but you can create conflict if you only emphasize one at the expense of the other. (Hmm, so does useit.com over-emphasize usability at the expense of aesthetics? I know a few folks who would love to hear that question answered.) He did contrast useit.com and MTV.com, saying that their different purposes prescribe different designs.

On “expert reviews”:

  • Expert reviews aren’t opinion based, but rather experience based.
  • Need to be done using general heuristics, more specific guidelines, and experts’ own test-based guidelines. Have to have all three as well as multiple experts.
  • Not an exact science—it’s a design process.
  • It’s a “very fuzzy type of thing to design user interfaces,” and there’s no one right answer.

On new ad formats:

  • Expanding ads (for example, where a car drives around the screen over content) aren’t unethical, but are “definitely evil.”
  • Popup ads—my screen is my castle
  • When overlaying content, user has to wait for the ad to get out of the way.
  • The web is “barely sufferable” already; we can’t make it worse. If the web gets more annoying to use, users will use it less.

The biggest problems facing the HCI discipline:

  • The lack of qualified staff.
  • 50 million user interface designs out there, but only 50,000 qualified people. Need 50 million different solutions—design isn’t a one-size-fits-all.
  • Need to figure out how to improve the efficiency of usability staff and software design processes. Guidelines are a partial solution.
  • New challenges coming up. For example, mobile, collaboration, integration of multiple devices, etc.
