Mobile Usability is Jakob Nielsen's first book that's fairly short ( pages). Back in , Jakob Nielsen deemed mobile usability an oxymoron: most sites had terrible usability, as designers were exploring the design.

The Flash software itself has already fixed most of the big usability problems that I complained about in earlier versions of Flash. Even though any software product can get better, the key priority is no longer to fix Flash, but to fix the Flash designers. Unfortunately, this is going to be harder, because I need to change the thinking of millions of designers and not just a few executives at Macromedia.
The Flash usability project has resulted in three deliverables so far: A thorough report on Flash usability with usability guidelines , based on a research project where we tested the usability of 46 Flash designs in the U. A preliminary report on how to make Flash designs more accessible and usable for users with disabilities, with 21 guidelines. The accessibility guidelines are only preliminary because we did not have sufficiently many accessible Flash applications available for the research study to come to firm conclusions.
We still decided to publish the accessibility report together with the other two deliverables because it is better than nothing and will be of some help to those Flash designers who want to increase the accessibility of their designs.
Hopefully, there will be more accessible Flash designs shipped in and we are already planning on producing a more comprehensive second edition once we have more data.
I am particularly pleased with our video because I think it will convince many Flash designers to pay more attention to usability once they see how real people struggle with many of the usability problems that are found in many current designs. SP: Will usability issues put the small design shop 10 employees or less out of business, or make them more competitive? Anybody can include usability in their design projects.
Designing Mobile Usability
Smaller companies could still do their own user tests by having one of the designers take on a part-time usability role. Check the design against established usability guidelines. This will discover many design weaknesses and will cause you to question some of your design decisions.
Run some user tests of other designs that attempt to solve similar problems as your own design.
In a real project, you should perform these activities in the opposite order of the one I listed: whenever you start a new project, learn from the usability of other designs, then create your own design and clean up its usability through guidelines, and finally test the revised design with real users.
SP: Which sites, in your opinion, do a good job of combining usability and visual attractiveness? SP: As input devices, the keyboard and the mouse are both hard-to-use and lead to repetitive-motion ailments. Speech recognition aside, what ideas do you have that could make computers more "usable" devices?
I think the main advances will come in display technology. We need much bigger screens and also higher resolutions. Truly high resolution will help with mobile usability by allowing for more information in a limited space, but PDAs will always be smaller than desktops.
In the future, it will surely be common to have a desktop monitor with 10, by 8, pixels or more.
Since Nielsen and Molich developed these heuristics in the s, technology has advanced and they are less attuned to many of the products available in the market today. For instance, Nielsen and Molich's heuristics would be too general to evaluate the usability of designs intended for online communities or mobile devices where the working environment is constantly changing.
However, the original heuristics are still largely applicable in spite of the specific capabilities and constraints of modern designs. Copyright terms and licence: Free to Use.
In combination with market research, other design guidelines and requirements, using your company or product-specific heuristics will better suit the design under scrutiny.
How to Generate and Conduct Your Own Heuristic Evaluation Choosing and developing new heuristics is a task in itself; there are no fixed recommendations, as each design presents its own set of different tasks, constraints, functions, styles and other variables. However, most heuristic evaluations involve between five and ten items, which are chosen on the basis of their applicability to the overall usability of the system, website, application etc. Less than five heuristics might lead to a lack of stringency when identifying potential problems and issues, but on the other hand, more than ten may overburden the evaluator as they must analyze the design with all of these heuristics in mind while the heuristics may also conflict with each other.
Make sure to combine them with other relevant design guidelines and market research. Select your evaluators.
Make sure to carefully choose your evaluators. Your evaluators should not be your end users. They should typically be usability experts and preferably with domain expertise in the industry type that your product is in. For example, an evaluator investigating a Point-of-Sale system for the restaurant industry should have at least a general understanding of restaurant operations. Brief your evaluators so they know exactly what they are meant to do and cover during their evaluation.
The briefing session should be standardized to ensure the evaluators receive the same instructions; otherwise you may bias their evaluation.
Within this brief, you may wish to ask the evaluators to focus on a selection of tasks, but sometimes they may state which tasks they will cover on the basis of their experience and expertise. First evaluation phase. The first evaluation generally takes around two hours, depending on the nature and complexity of your product.
The evaluators will use the product freely to gain a feel for the methods of interaction and the scope. They will then identify specific elements that they want to evaluate. Second evaluation phase.

In the second evaluation phase, the evaluators will carry out another run-through, whilst applying the chosen heuristics to the elements identified during the first phase. The evaluators would focus on individual elements and look at how well they fit in the overall design. Record problems. The evaluators must either record problems themselves or you should record them as they carry out their various tasks to track any problems they encounter. Be sure to ask the evaluators to be as detailed and specific as possible when recording problems.
Debriefing session.But only the most senior usability professionals can take a range of findings and generalize them into guidelines that will apply to new cases. The less you can see. Net-a-porter Figure 4. Speech recognition aside, what ideas do you have that could make computers more "usable" devices? Thus navigation difficulties or other user interface issues cannot explain the increased difficulty.
The full data from our survey give rise to a slightly complicated mathematical model that relates project size to recommended spending on usability. On behalf of the SitePoint community, thanks for taking the time to chat with us!
