Graphical controls based environment for user interface evaluation
For more than two decades, the HCI community has elaborated numerous tools for user interface evaluation. Although the related tools are wide, the evaluation remains a difficult task. This paper presents a new approach for user interface evaluation. The proposed evaluation process focuses on utility and usability as software quality factors. It is based on the UI ergonomic quality inspection as well as the analysis and the study of the Human-Computer interaction. The proposed approach is mainly based on graphic controls dedicated to the user interface evaluation. These controls have, on the one hand, the role to compose graphically the interfaces. On the other hand, they contribute to the UI evaluation through integrated mechanisms. The evaluation is structured into two phases. The first consists of a local self-evaluation of the graphical controls according to a set of ergonomic guidelines. This set is specified by the evaluator. The second allows an electronic informer to estimate the interaction between the user interface (graphically composed by the evaluation based controls) and the user.
Evaluation Based Graphical Controls: A Contribution to Mobile User Interface Early Evaluation
In this paper, we present a set of graphical controls intended for the coupling between the design and the evaluation of mobile user interfaces. It is a contribution to user interface early evaluation. The presented controls include mechanisms aiming to inspect their consistency according to a predefined set of ergonomic guidelines. We also report on the proposed approach current implementation, and an example of application.
The evaluation of the interactive systems has been the subject of numerous researches during the last two decades. However, it still remains a difficult task to establish. Generally, evaluators exploit a single method to proceed to an interactive system evaluation. However, many authors assert that a single method is not enough to obtain relevant evaluation results. As a solution, we propose a decision-making approach for the synthesis of data collected by different evaluation methods to obtain more reliable evaluation results. The proposed approach is based on three evaluation methods: the questionnaire, the ergonomic quality inspection and the electronic informer. As an evaluation result, the proposed approach provides evaluators with the quantification of the evaluation dimensions: the usability and the system functionality degree.
Metric-Based Evaluation of Graphical User Interfaces: Model, Method, and Software Support
Many factors contribute to ensuring User eXperience (UX) of Graphical User Interfaces, such as, but not limited to: usability, fun, engagement, subjective satisfaction. Aesthetics is a potential element that could also significantly contribute to this user experience. Although aesthetics have been extensively discussed, there is a need to rely on a sound, empirically validated methodology in order to properly evaluate how aesthetics could be measured, namely through metrics. Two main issues need to be addressed: the representativeness and the relevance of aesthetics metrics. In order to address these challenges, this paper introduces a methodology for metric-based evaluation of a graphical user interface of any type. This methodology is based on an underlying model that captures aesthetics aspects and related metrics, a method for computing them based on the underlying model, and software that supports enacting this method on any type of graphical user interface.

Towards a practical method of user interface evaluation.
This paper describes a practical method for evaluating the usability of human-computer interfaces. The paper specifies the requirements of such a method, and then outlines our work in developing a method to meet this specification. The method is based on the conduct of realistic tasks with an interactive system and the subsequent systematic elicitation of end-users' and designers' reactions to the interface using a criterion-based evaluation checklist.
Knowledge-based evaluation as design support for graphical user interfaces
Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '92, 1992
The motivation for our work is that even though user interface guidelines and style guides contain much useful knowledge, they are hard for user interface designers to use. We want to investigate ways of bringing the human factors knowledge closer to the design process, thus making it more accessible to designers. TO this end, we present a knowledge-based tool, containing design knowledge drawn from general guideline documents and toolkit-specific style guides, capable of evaluating a user interface design produced in a UIMS. Our assessment shows that part of what the designers consider relevant design knowledge is related to the user's tasks and thus cannot be applied to the static design representation of the UIMS. The final section of the paper discusses ways of using this task-related knowledge.
How to Measure the Ergonomic Qualitiy of User Interfaces in a Task Independent Way
The main problems of standards (e.g., ISO 9241) in the context of usability of software quality are, that they can not measure all relevant product features in a task independent way. We present a new approach to measure user interface quality in a quantitative way. First, we developed a concept to describe user interfaces on a granularity level, that is detailed enough to preserve important interface characteristics, and is general enough to cover most of known interface types. We distinguish between different types of 'interaction points'. With these kinds of interaction points we can describe several types of interfaces (command, menu, form-fill-in, desktop, direct manipulation, multimedia etc.). We analysed the outcomes of three different comparative usability studies to validate our quantitative measures. The results of a published comparative usability study by someone else can be predicted. Results of six different interfaces are presented and discussed. One of the mo...
User interface evaluation in the real world: A comparison of four techniques
1991
evaluation; guidelines; usability testing; cognitive walkthrough A user interface (UI) for a software product was evaluated prior to its release by four groups, each applying a different technique: heuristic evaluation, software guidelines, cognitive walkthroughs, and usability testing. Heuristic evaluation by several ill specialists found the most serious problems with the least amount of effort, although they also reported a large number of low-priority problems. The relative advantages of all the techniques are discussed, and suggestions for improvements in the techniques are offered.
