Transferring Knowledge of User Interfaces Guidelines to the Web

This paper reports on the work that has been done by the teams above within the EvalWeb project. The work presented here describes how ergonomic rules, that are valid for the design of graphical user interfaces, should be refined and extended in order to be suitable for the ergonomic design and evaluation of web sites. To this end a distinction is made between web user interfaces and classical WIMP ones.

A generic framework based on ergonomics rules for computer aided design of user interface

Ergonomic rules are supposed to help developers to build UI respecting human factor principles. Unfortunately, studies carried out with designers show that guidelines are difficult to apply at design time. The difficulties encountered by designers is mainly due to the structuring of the guidelines and the way they are formulated. This is due to the fact that, at the origin, ergonomic rules were dedicated to people with skill knowledge in cognitive science and ergonomics. At present time these rules are widely available and developers want to use them. This paper presents a method for structuring ergonomie rules in order to make them usable by developers. This method can be used for any set of ergonomie rules and is applied on an example.

User Interface Evaluation : is it Ever Usable?

Publisher Summary This chapter describes that the availability of guideline knowledge is not enough in order to provide helpful and efficient information to the agents involved in the design process of an interactive application. By showing the different points of view of those agents towards the user interface (UI), the chapter explains why it is so difficult to provide relevant and easy to use information. The chapter describes two different projects addressing the question—first question aims at evaluating and proposing solutions for the improvement of the interactive applications previously developed, while the second question aims at providing a set of tools for the automated design of interactive applications taking into account guidelines for user interface design. Coupling automated UI generation and evaluation is considered as a key future work: it is sound to evaluate a particular UI that have been automatically generated with the same ergonomic criteria and guidelines that have been used to produce it.

What Kind of Verification of Formal Navigation Modelling for Reliable and Usable Web Applications

In this paper we introduce briefly a notation dedicated to model navigation of Web applications and we discuss some strategies to assess the usability over navigation models built with such as a notation. Our aim with this kind of evaluation is to ensure (prior to implementation) that important users tasks can (or cannot) be performed using the system.

Vérification de règles ergonomiques sur un modèle de navigation des applications web

If Web usability guidelines can play an important role for ensuring usability when designing and evaluating web application, the moment and the way to use them still remain unclear. This paper presents a preliminary study and a classification of ergonomic rules about web applications navigation. Secondly, we describe our approach to apply these rules directly to a navigation model (SWC).
