Usability measure user preferences and performance of interaction with a system. Criteria for usability evaluation vary system to system depending upon the selection among wide variety of usability parameters. To enhance the acceptability of biometric based identification among large population usability evaluation of HumanBiometrics Sensor Interaction (HBSI) is highly important. This paper pro...

Usability is an important quality characteristic of software (SW) products and systems. Usability costbenefit analysis models outline the potential benefits and costs of usability. These models are important for selling the usability activities for management. The implications of open source software (OSS) development context on usability cost-benefit considerations have not been addressed. Bas...

Usability has gained a lot of attention in the design community and it is one of main goals of every design project. Evaluating usability is usually done with end-users after a prototype has been built and there are not many techniques available that allow usability evaluation during the early design phases. Current dialog modeling techniques generally do not deal with usability aspects, as the...

Currently, minimal requirements exist for assessing the usability of electronic health record (EHR) systems. Usability requirements are especially lacking for the increasing use of mobile devices to access EHRs. Therefore, the authors investigated the usability of three commercially available certified ambulatory EHR systems as accessed on mobile devices. The study used the System Usability Sca...

This thesis explores whether usability cost-benefit analysis is helpful when applied to commercial and open source software (OSS) development contexts. First, the thesis examines the differences and commonalities among the existing usability cost-benefit analysis models. The results indicate that there are considerable variations in the usability cost-benefit analysis literature in how the diff...

Usability engineering for products is an increasing sales argument for industrial and consumer products. Products and services are designed for target-group adequate usability. But usability is no single-value concept. In contrast, EN ISO 9241 points out that it is influenced by several moderators, e.g., efficiency, context of use and others. Although standardized questionnaires have been devel...

UNLABELLED A longitudinal field experiment was carried out over a period of 2 weeks to examine the influence of product aesthetics and inherent product usability. A 2 × 2 × 3 mixed design was used in the study, with product aesthetics (high/low) and usability (high/low) being manipulated as between-subjects variables and exposure time as a repeated-measures variable (three levels). A sample of ...

Many different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experience...

In the last decade, the research of the usability of mobile phones has been a newly evolving area with few established methodologies and realistic practices that ensure capturing usability in evaluation. Thus, there exists growing demand to explore appropriate evaluation methodologies that evaluate the usability of mobile phones quickly as well as comprehensively. This study aims to develop a t...
