Jakob nielsen discount usability thesis

This thesis will investigate the possibility of developing a similar approach for Internet security. The student will build on top of existing methodologies and technologies to develop cost-oriented approaches to internet security testing. This project will develop a web application to support small Prince2 projects. This is a thesis that requires both business and software development skills. Access to a development box will be provided under those conditions.

The student taking this thesis will develop a server-side module planner, to be used by university programmes to manage dependences between modules. The planner will give allow to easily know which modules students have to take and which ones are optional, and would allow them to correctly plan their studies.

For a number of years researchers have been developed tools for doing automatic web usability testing. As part of the thesis, the student will have to develop software to support the usability testing and for organising the results. The student is expected to investigate the levels of usability in the different areas of the Dmoz database and to answer to questions as: Are there any categories of web sites which have more usability problems? Which ones? Are there any categories in which the usability is typically higher?

This thesis has been assigned in February to Alexander Rukshan and has been submitted in May Norman describes the ways in which poor design frustrates people when they use everyday objects like telephones, refrigerators, and doors.

It is a liberating book, because you can recognize difficulties that once made you feel stupid or inept as limitations of the design and not of the user. Nielsen's book occasionally has the same effect.

Once you have read Nielsen's advice, it becomes hard not to notice examples of bad design as you browse the web. When I visit a hard-to-use site, it often seems clear that Nielsen's advice would have made the site easier to use. It's not that the web is inherently hard to use or that I can't figure out a particular site; the site's designers are to blame. Where Nielsen's design strategies reflect concerns of the moment and the limitations of today's web technology, the authors represented in Information Design look at a broader swath of design issues and technologies.

The book contains 16 essays organized into three sections -- one on theoretical foundations, one on practice, and one of design for information technology. Many of the authors take up the question of whether there is a specific practice that can be usefully labelled "information design. The specific conversation or discourse may be a multi-user virtual world, a large, collaborative art project about public transit in Seattle, or a library reference desk. The great diversity of voices in Information Design makes its hard to categorize. Some of the essays are technical or theoretical, others simply relate experiences with a design project or try to directly inform practice.

The essays range widely in length and tone -- from C.

Screven's page piece on design in museums and public spaces, to a page piece on virtual worlds by Simon Birrell, a video game designer. Screven's scholarly piece, containing 93 citations, takes a textbook approach to describing communications and learning in a museum setting.

Birrell's piece, transcribed from a talk given at the CyberConf in , argues for the importance of the characters, narrative, and interactivity of a virtual world over the 3-D graphics used to paint the world on a display. The collection is strongest when it focuses on practice and relates the experiences of individual designers. Some of the theoretical pieces tend towards highly abstract discussions of their topics and reach broad or vague conclusions that seem hard to substantiate.

For example, Yvonne Hansen's essay on Graphic Tools promotes her design approach as a "simple, easy-to-learn graphical language that is universally applicable to all subjects. The notion that graphical languages have value for planning and thinking is hard to disagree with. It is less clear that a specific formalism for shapes and their meanings could be universally meaningful or applicable. Brenda Dervin's overview of her Sense-Making approach is also problematic. Inspired by Continental philosophers including Foucault, Habermas, and Lyotard, she describes a theory, methodology, and practice for information design involving a postmodern notion of information as "a tool designed by human beings to make sense of a reality assumed to be both chaotic and orderly.

The essay focuses primarily on the highly abstract framework, however, and ends up offering little evidence of how the theory could inform practice. Librarians, Dervin suggests, should develop a model of how patrons make sense of information; i.

Other essays focus on less universal themes. One of the most interesting and practical contributions to the collection is Roger Whitehouse's essay, titled "The Uniqueness of Individual Perception. Whitehouse's work is an example of wayfinding , a study that focuses on the ability to navigate an architectural or geographic space. It is specifically concerned with the decision making and problem solving skills involved in reaching a destination.

Romedi Passini's essay also discusses wayfinding, but in a large urban setting and from a more general perspective. The central message of Whitehouse's essay is that each individual has a unique perspective or viewpoint that effects the success of a particular design. While the designer cannot practically plan for every person's individual needs, she should work to make sure no group of people is left out. If a designer focuses on an idealized average user, she may end up with a design that works well for no specific group of users.

The specific design challenges posed by visually impaired users illustrate the point well. Whitehouse describes tests he used to design typefaces and maps that could be used by several different groups of users, including people with reduced vision caused by aging, people with partial or total blindness caused by accident or disease, and people who were born blind.

The needs of each group are different, and it was not always possible to find a single solution that accommodated everyone. To make effective design decisions, Whitehouse relied on user testing. While carefully collected clinical data and research would be the best guide, there is often little data available to inform a particular decision. In these cases, Whitehouse says "what we can do -- and do with relative economy -- is obtain some less tidy information by conducting simple real-life tests in real-life situations.

Though what users like and what works best for them may not be the same. Can these varied ideas about information design be applied to the challenges of designing usable web sites or digital libraries? Jacobson points to Dervin's work on Sense Making and Passini's work on wayfinding as subjects that may affect future design approaches.
