The role of Perceived Usability, reputation, satisfaction and consumer familiarity on the website loyalty formation process
Computers in Human Behavior, 2008Co-Authors: Luis V. Casaló, Carlos Flavián, Miguel GuinalíuAbstract:The increasing competitiveness in electronic business is motivating varying research on the principal antecedents of consumer loyalty. However, previous research is too scarce, so that there are notable aspects which must be analyzed in-depth. This research has focused on new topics about the development of online consumer loyalty, such as the role of familiarity and Usability. Firstly, we analyze the effect of Usability, reputation and satisfaction on consumer loyalty. The results have revealed the existence of a positive and significant influence of reputation and satisfaction on website loyalty. Secondly, we confirm the influence of Usability on consumer satisfaction. Thirdly, we assess the moderating role of consumer familiarity on the relationships proposed in the research model. The analyses have shown that Usability plays a special role in the loyalty formation process. At reduced levels of familiarity Usability influences on loyalty through consumer satisfaction (indirect effect). However, if familiarity increases then Perceived Usability influences on loyalty not only through its effect on satisfaction, but also in a direct way. Consequently, higher levels of familiarity mean that the weight of Usability in the explanation of website loyalty is higher. Finally, several conclusions, managerial suggestions, limitations and future research lines are proposed.

The role played by Perceived Usability, satisfaction and consumer trust on website loyalty
Information & Management, 2006Co-Authors: Carlos Flavián, Miguel Guinalíu, Raquel GurreaAbstract:We performed a study to determine the influence that Perceived Usability has on the user's loyalty to websites that they visit. The results of the empirical analysis confirmed that the trust of the user increases when the user Perceived that the system was usable and that there was a consequent increase in the degree of website loyalty. In the same way, greater Usability was found to have a positive influence on user satisfaction, and this also generated greater website loyalty. Finally, it was found that user trust was partially dependent on the degree of consumer website satisfaction.

Understanding the Influence of Perceived Usability and Technology Self-Efficacy on Teachers' Technology Acceptance.
Journal of Research on Technology in Education, 2011Co-Authors: Heather Holden, Roy RadaAbstract:AbstractThe Technology Acceptance Model (TAM) represents how users come to accept and use a given technology and can be applied to teachers’ use of educational technologies. Here the model is extended to incorporate teachers’ Perceived Usability and self-efficacy measures toward the technologies they are currently using. The authors administered a survey to K–12 teachers in two rural school districts in Virginia, and 99 teachers responded. We then analyzed the responses with both reliability statistics and general linear modeling techniques. The results indicated that the incorporation of Perceived Usability into the TAM explained more variance and was more influential to TAM elements than its absence, thereby supporting the importance, positive influence, and necessity of evaluating Usability when investigating educational technology acceptance and usage behavior. Furthermore, the study found teachers’ technology self-efficacy (TSE) was more beneficial to the TAM than their computer self-efficacy (CSE); ...

flexible work arrangements exploring the linkages between Perceived Usability of flexible work schedules and work life balance
Community Work & Family, 2009Co-Authors: Jeremy HaymanAbstract:The relationship between the Perceived Usability of flexible work schedules and work/life balance was explored with 710 office-based employees. Direct linkages were found between Perceived Usability of flexible work schedules and the three dimensions of work/life balance (work interference with personal life, personal life interference with work, and work/personal life enhancement). In addition, employees operating under flexitime work schedules displayed significantly higher levels of work/life balance than their counterparts utilising traditional fixed-hour schedules. However, non-significant differences in the levels of work/life balance were found between two other flexible work schedules (flexiplace and job share) and fixed-hour work schedules. Consequently, while individual flexible work schedules may have a marginal overall positive impact on employee work/life balance, the Perceived Usability and availability of these work schedules appears to be a key element in achieving work/life balance for ma...

Perceived Usability of e government web sites affecting the user satisfaction and the revisiting
Journal of Information Systems, 2007Co-Authors: Daeho ByunAbstract:The previous studies regarding the Usability evaluation of e-government web sites focused only on deriving affecting factors and variables. They did not find the relationship of Usability, user satisfaction and revisiting. The objective of this paper is to find the causal effect how the Usability of e-government web sites affect to the user satisfaction and the revisiting attitude. no scope of e-government web sites included the portal site and ie liked web sites. We developed a structural equation model and performed a user test. As a result, a Perceived Usability affected the revisiting, but it did not intermediate the user satisfaction.

implicit factors related to greek older adults Perceived Usability of online technologies an exploratory study
Pervasive Technologies Related to Assistive Environments, 2020Co-Authors: Diogenis Alexandrakis, Konstantinos Chorianopoulos, Nikolaos TseliosAbstract:Our experiences are neither independent of the tools we use nor of our perceptions. Culture can also affect people's conceptions upon a variety of issues, ranging from feelings of loneliness to technology Usability. As for the latter, it seems that Greek older adults make use of web technologies much less than the majority of their peers in Europe. Based on the fact that psychosocial attributes can also affect technology usage, this exploratory quantitative research is an attempt to focus on the implicit factors related to Greek older adults' Usability ratings of web technologies. For this aim, a web 2.0 storytelling prototype has been demonstrated to 112 participants and an online questionnaire was applied for data collection. According to findings, older adults' loneliness and future time perspective were associated with system Usability, whereas their chronological age did not have any statistically significant relationship with Usability. These outcomes, which are extensively discussed, contribute to the limited literature in the field by studying the interactions between older people's psychosocial attributes and their Perceived Usability of online technologies.

Perceived Usability evaluation of learning management systems empirical evaluation of the system Usability scale
The International Review of Research in Open and Distributed Learning, 2015Co-Authors: Konstantina Orfanou, Nikolaos Tselios, Christos KatsanosAbstract:Perceived Usability affects greatly student’s learning effectiveness and overall learning experience, and thus is an important requirement of educational software. The System Usability Scale (SUS) is a well-researched and widely used questionnaire for Perceived Usability evaluation. However, surprisingly few studies have used SUS to evaluate the Perceived Usability of learning management systems (LMSs). This paper presents an empirical evaluation of the SUS questionnaire in the context of LMSs’ Perceived Usability evaluation. Eleven studies involving 769 students were conducted, in which participants evaluated the Usability of two LMSs (eClass and Moodle) used within courses of their curriculum. It was found that the Perceived Usability of the evaluated LMSs is at a satisfactory level (mean SUS score 76.27). Analysis of the results also demonstrated the validity and reliability of SUS for LMSs’ evaluation, and that it remains robust even for small sample sizes. Moreover, the following SUS attributes were investigated in the context of LMSs evaluation: gender, age, prior experience with the LMS, Internet self-efficacy, attitude towards the Internet and usage frequency of the LMS.

does size matter investigating the impact of mobile phone screen size on users Perceived Usability effectiveness and efficiency
Human-Computer Interaction with Mobile Devices and Services, 2013Co-Authors: Dimitrios Raptis, Nikolaos Tselios, Jesper Kjeldskov, Mikael B SkovAbstract:Given the wide adoption of smartphones, an interesting debate is taking place regarding their optimal screen size and specifically whether possible portability issues counterbalance the obvious benefits of a larger screen. Moreover, the lack of scientific evidence about the concrete impact of mobile phones' screen size on Usability raises questions both to practitioners and researchers. In this paper, we investigate the impact of a mobile phone's screen size on users' effectiveness, efficiency and Perceived Usability as measured using System Usability Scale (SUS). An experiment was conducted with 60 participants, which interacted with the same information seeking application on three different devices of the same brand that differed on their screen size. A significant effect of screen size on efficiency was derived, leading to an important finding that users who interact with larger than 4.3in screens are more efficient during information seeking tasks.
