This paper presents the results of a study that compared two think-aloud usability testing methods: the concurrent think-aloud and the retrospective think-aloud methods. Data from task performance, testing experience, and usability problems were collected from 30 participants equally distributed between the two think-aloud conditions. The results suggest that while the thinking aloud method had no impact on task performance and testing experience, participants using the concurrent think-aloud method reported a larger number of problems with the test interface than participants using the retrospective think-aloud method. These findings suggest a reason for preferring the concurrent think-aloud method to the retrospective one.

موجز عن البحث:

Both the rapid advances in wireless technologies and the high proliferation rate of mobile communication services and artefacts have had a profound impact on industry, and are beginning to offer interesting and advantageous new services. In particular, the mobile transaction (m- transaction) system has emerged, enabling users to pay for physical and digital goods and services using their mobile devices whenever they want, regardless of their location. Although it is anticipated that m-transactions will enjoy a bright future, there is apparently still reluctance among users to accept mobile transactions, particularly in Saudi Arabia. Furthermore, it is believed that usability is critical to the success and acceptance of mobile technology innovations in general, and m-transactions in particular. While most of the research into IT innovation acceptance is based on TAM (Technology Acceptance Model) and its many variants, the literature review reveals that there is little research on mobile application usability as an important antecedent factor for the success and acceptance of mobile technologies. This is particularly true in developing countries, especially the Middle East, therefore this project aims to fill this gap in the research. This paper is an extension of four previous studies by the authors, which indicated that usability is the most influential factor in Saudi users’ intentions of utilising mobile transactions. It aims to investigate and empirically test the usability level of mobile transactions from the perspective of Saudi users; this will be achieved by conducting usability experiments with real mobile applications within the target group. In other words, this study is a part of a larger research project and it serves as a validation/verification tool to answer the question “Why does the ease of use of mobile transactions have the highest impact on the intention to use mobile transactions in Saudi Arabia?” Moreover, it will produce a set of empirically-based recommendations for the developers and providers of mobile applications who are interested in the Saudi market. The results of the this study showed that the usability of the tested application, which is considered one of the most popular commercial mobile application in Saudi Arabia, (i.e. ‘Souq.com’), is unsatisfactory, with an average SUS Score of 50. Not surprisingly, this low usability negatively affected the willingness of the participants to use the application again.

The Impact Of Usability Of Online Library Catalogues On The User Performance

ملخص المشاركة:

The rapid evolution of Information Technologies (IT), especially with the coming of the Internet, has existed online library catalogues which have a vital part to play in Educational life. The online library is a type of information retrieval system. It is a library in which collections are stored in digital formats. These formats may be stored locally or entered remotely via computer networks. To assess the success of online library catalogues; usability criteria should be considered to ensure that users can find their way quickly and easily to e-resources. This paper aims to use thinking aloud protocol to evaluate two distinct interfaces of library catalogues to examine how their usability problems significantly impede user performance. The results show that the usability is the main factor affecting users’ performance, and it is the best attribute to measure the extent to which the online library catalogues meets the requirements of their users.

Thinking About Thinking Aloud: An Investigation Of Think-Aloud Methods In Usability Testing

ملخص المشاركة:

Usability has become an imperative aspect of survival on the web, thus, it has always been considered as a crucial aspect of web design. This paper presents the results of a study that compared two think-aloud usability testing methods: the concurrent think-aloud and the retrospective think-aloud methods. Data from task performance, testing experience, and usability problems were collected from 40 participants equally distributed between the two think-aloud conditions. The results found that while the thinking aloud method had no impact on task performance and participants testing experience, participants using the concurrent think-aloud method detected a larger number of minor problems with the test interface than participants using the retrospective think-aloud method. These findings suggest a reason for preferring the concurrent think-aloud method to the retrospective one.
