Software usability became an important quality factor in recent years due to the increasing demand of interactive software systems. Now mostly systems are developing using object-oriented methodology. The object-oriented methodology reduces design complexity, so enhances usability. Also objectoriented approach improves the usability of software system when software engineering process combined ...

Usability is an important quality characteristic of software (SW) products and systems. Usability cost-benefit analysis models outline the potential benefits and costs of usability. This paper contrasts usability cost-benefit analysis literature with an empirical case in industrial setting, in which usability cost-benefit considerations (along with other usability activities) resulted in usabil...

This research conceptualizes mobile application usability and develops and validates an instrument to measure the same. Mobile application usability has attracted widespread attention in the field of human–computer interaction because well-designed applications can enhance user experiences. To conceptualize mobile application usability, we analyzed Microsoft’s mobile usability guidelines and lo...

Usability assessment plays a fundamental role in discovering usability problems and the determination of the level of usability for a given software product. One crucial aspect in every usability assessment is the estimation of the sample size desired for a software product. Once we start estimating the sample size needed for a usability assessment, a baffling question comes in mind: “how many ...

Empirical study on usability impact factors of electronic wallet-one card solution within college students includes the analysis of the current situation within the electronic wallet-one card solution for college students, the analysis of behavior habit within using the electronic wallet-one card solution for college students, and sets up a preliminary usability evaluation indicator system of e...

Software usability is a important factor in evaluating the quality of any software. All the software quality model has consider the usability as one of the most important criteria of judging the performance of any software. Different methods have been employed to calculate usability, but in this paper we are providing a very simple technique in this paper. This paper also provides a method by w...

Over the past few decades, Usability has emerged as an extremely important quality factor. Many methods have so far been proposed for usability evaluation but they lack in one way or another. This paper proposes a method for software usability quantification using the fuzzy multiple criteria weighted average approach. This approach has been chosen due to the highly unpredictable nature of the a...

In this paper the author analyses the grid computing paradigm and attempts to show how the established principles of usability engineering, interaction design and other user-centred design methodologies can be applied to this paradigm to “re-factor” it so that it addresses usability concerns. Usability issues are illustrated with examples from the Globus ToolkitTM ([1]).

The objective of this chapter is to clarify the role of usability processes and methods within the software life cycle. After discussing the concept of usability as quality factor and providing various definitions, including those in ISO standards, it presents the user-centered design methodology for designing usable systems and provides indications on how to include usability in the software l...
