Eyetrack project reveals how people perceive new sites
|
»A very interesting eyetrack research project looked through the eyes of 46 people to learn how they see online news. It's impossible to summarize the many findings, but here are some highlights:
- Headlines had less than a second of a site visitor's attention
- Smaller type encourages focused viewing behavior
- Larger type promotes scanning
- Shorter paragraphs get more attention than longer ones
- People often looked only at the first couple of words in blurbs
- People typically looked below the first screen
- Navigation placed at the top of a homepage performed best«

90% der Usability-Tests sind nutzlos
|
|
Lane Becker: »Ninety percent of all usability testing performed on Web sites is useless. This is not to say that it doesn’t have a significant role to play in user experience design. When done right, usability testing will improve your Web site and your development process, but the current culture surrounding Web site usability testing is such that it rarely benefits the design. Worse, this misapplication can undermine the acceptance of this important technique throughout an organization.« Der Beitrag trifft den Kern meiner seit Jahren anhaltenden Kritik des Usability Engineerings (s. "Designer und die Brauchbarkeit" vom 25. November 2000). Damals appelierte ich an die Designer sich gewissenhafter mit der berechtigten Kritik des Usability Engineerings am zeitgemäßen (Web-)Design auseinanderzusetzen und das verfehlte Empirieverständnis der UE-Fraktion präziser anzugreifen.

Testing the Three-Click Rule
|
Josh Porter: »In our studies, users complain about how long it takes to find things all the time. This is one way that users vocalize their frustration. They tell us that if they could only reduce the number of frustrating clicks the site would be better.
However, these complaints aren't actually about the clicks. They are really complaints about failing to find something. When users find what they want they don't complain about number of clicks.
We see this phenomenon quite often: users complain about a symptom and not the real problem that caused it. They want to explain why they are failing, and in this particular case, one of their initial thoughts is that they are clicking too much.«

Usability cult sacrifices innovation

James Woudhuysen: »Making things usable, does not mean that those things will necessarily be useful. [...] Society has dethroned one elite, only to ensconce another. Instead of 40- or 50-year-old white-coated "technology push" scientists and engineers, we now prefer hip 20- and 30-somethings, intent on being "inclusive" in their designs and on upholding the rights of the consumer everywhere they go.«

Psychologen ermitteln zehn Webdesign-Gebote
|
"Jeder Web-Designer kennt die typischen Regeln, wie professionell gestaltete Internet-Präsenzen auszusehen haben. Schnell im Aufbau, leicht zu bedienen und auch schön sollen sie sein. Psychologen der Technischen Universität Chemnitz sind diese Anforderungen allerdings zu ungenau. Sie haben deshalb innerhalb von vier Jahren im Rahmen der Chemnitzer Forschergruppe "Neue Medien im Alltag" mehr als 300 Internetnutzer auf ihre Surf-Gewohnheiten hin untersucht. Mittels Infrarottechnik erfassten die Psychologen die Blickbewegungen der Probanden, während diese Webseiten betrachteten. Gemessen wurden auch Lesezeit, Navigation und Erinnerungsvermögen."

Keep it simple - Simplicity vs. Innovation
|
"Not surprisingly, the simple = dull equation is a fundamental part of the mental make-up of all web designers, who have fallen in love with the endless empty spaces of the web. Web design is attractive because designers want to leave their mark on these spaces and fill them with new ideas. Yet, on the web, there are few fundamental rules; therefore, your ideas could become the new fundamental rules."

Warum JavaScript Links enorm stören
|
|
Um auf Websites einem Link folgen zu können, ohne die aktuelle Seite verlassen zu müssen, mache ich exzessiven Gebrauch der Funktion "Diesen Link in neuem Fenster öffnen". Mozilla macht diese Funktion (abgeguckt von Unix-Netscape) bequem über die mittlere Maustaste zugänglich, andere Browser bieten Ctrl-Klick oder Apfel-Klick oder, umständlicher, Rechtsklick und Auswahl aus dem Kontextmenü.
Das funktioniert leider nicht mit Links, die href="javascript:..." oder href="#" onclick="" enthalten. Stattdessen öffnet sich ein leeres Browserfenster, das ich schliessen muss, um auf der Ursprungs-Seite den Link auf dem vom Web-Developer für geeigneter gedachten Weg zu öffnen. Wie ignorant!
Bin ich der einzige, den das maßlos stört?

The myth of optimal web design
|
Scott Berkun: Perfection in design is not possible. No matter how much is known about a given business, user group or technology, you can not simultaneously satisfy all possible objectives. For any website or user interface, there are no mathematics, and no algorithms, for deciding which objectives to satisfy in a single design, or even for accurately defining an optimal solution within any of those objectives. There are usability, design and business methods that effectively evaluate and illuminate promising directions , but they are sensitive tools, that work more as guides, rather than maps. In general, any form of design involves too many simultaneous possible objectives and forms of solutions to enable any overall mathematical or algorithmic based confidence. An optimal design, in the broadest sense, is a mythical idea. (via lucdesk)

When Web pages don't work
|
User-experience design will continue to play an increasingly important role in attracting and maintaining customers on the Web. It is not enough to attract surfers to your site. To transform surfers into purchasers, your site must be easy to navigate, predictable, and quick. Although successful user-experience design is not the only factor in effective Web commerce, it is a critical component that can make or break your site. It pays to pay attention to what your users experience. Your competition does.

Guideline dogma

Nobody would deny that usability guidelines, applied in context by a usability professional, are extremely valuable in guiding a website evaluation. The problem occurs when non-professionals apply these guidelines out of context. This can result in an unimaginative site that looks bland and homogenous. To design usable sites that truly engage customers we need to replace simple guidelines with a customer-centred design process. (via xblog)

Invasion of the Usability Experts

Dale Dougherty: Use drop-down boxes sparingly, says Jakob Nielsen in an article on his site, useit.com. In this case, It bothers me that he makes his point by citing a ludicrous example of a person onstage at a trade show trying to select street type (Road, Street, Circle, Avenue) from a drop-down box. What worries me is that Nielsen's remarks are being translated by others into a ready-made Web design doctrine: "Don't use drop-down boxes." Armed with such catch phrases, the one-minute manager begins to lock down what designers do. Nielsen's work is important, but please use his conclusions sparingly.

Aesthetics and Usability
|
Kiana K. Matthews: Aesthetics is the discipline that gives designers the tools to take care with color, typography, layout, icons, graphics, and coherency. There are specific recommendation for how to use the components in an effective and pleasing way. It would be folly to ignore them. In this paper, I have provided a survey of some aesthetic guidelines and tried to relate them to specific usability benefits or hindrances. As more research is being done, it become clearer that aesthetics and usability can go hand in hand. I believe that aesthetics, for this reason, should become a standard and important part of the HCI curriculum and discipline. (via bogieland)

Human Interace Online - Form and Fashion
|
Peter Bickford: In truth, usability and aesthetics come from separate branches of the family tree. But the family resemblance is strong enough that they've often gotten away with using each other's ID card to bluff their way into the company beer bash. This confusion of form with function has been brought to a new extreme with the rise of the web. Perhaps never before has sheer style been so central to interface design. The chief reason for this, of course, is that there's been very little of substance that even a good interface designer could do to make the web more useful.

Usability Is Not Graphic Design
|
|
Jon Meads: As usability consultants, we're often asked by potential clients to bring in a portfolio of "screens" that we've designed. But we don't have any, because we don't design "screens"; we design interaction, the intended behavior by which people will use a product or a web site. These requests from clients illustrate a problem with much of the web site development that's being done today: too often, usability is equated with graphic design. If viewers aren't staying with your web site, then the graphics need to be improved. The site has to be more eye-catching -- to "wow" the viewer.
Graphic design is important, and wowing the viewer can be desirable, but graphic design is not the same as usability. This is an important distinction. After you wow the viewer, what are you going to do for a second act? Wow them again? And after that? [...]

User Interface Engineering
|
|
Our research shows that the vast majority of usability problems come from a single cause: someone on the development team didn’t know a key piece of information. And if they had known that information earlier, they’d have designed the product to accommodate it, making the usability problem go away.
...
We don't want you to blindly believe everything we say. We'd rather show you how to spot the evidence yourself and draw your own conclusions--that's designing with your eyes open.
You'll test several web sites (including your own, if you wish) to explore our findings for yourself. We'll show you some things to look for, and you'll conduct short usability tests in small teams. It's great if you've done usability testing before, but it's fine if you haven't.
