An Empirical Evaluation of the System Usability Scale

Abstract: This article presents nearly 10 year's worth of System Usability Scale (SUS) data collected on numerous products in all phases of the development lifecycle. The SUS, developed by Brooke (1996), reflected a strong need in the usability community for a tool that could quickly and easily collect a user's subjective rating of a product's usability. The data in this study indicate that the SUS fulfills that need. Results from the analysis of this large number of SUS scores show that the SUS is a highly robust and versatile tool for usability professionals. The article presents these results and discusses their implications, describes nontraditional uses of the SUS, explains a proposed modification to the SUS to provide an adjective rating that correlates with a given score, and provides details of what constitutes an acceptable SUS score.

IBM computer usability satisfaction questionnaires: psychometric evaluation and instructions for use

Abstract: This article describes recent research in subjective usability measurement at IBM, focused on evaluating the psychometric properties of questionnaires designed for use in scenario‐based usability evaluation The questionnaires address evaluation at both a global overall system level and at a more detailed scenario level The primary goals of this article are to (a) discuss the psychometric characteristics of IBM questionnaires that measure user satisfaction with computer system usability, and (b) provide the questionnaires, with administration and scoring instructions For scenario‐level measurement, the 3‐item After‐Scenario Questionnaire (ASQ) has excellent internal consistency, with coefficient alphas across a set of scenarios ranging from 90 to 96 For more global assessment, the Post‐Study System Usability Questionnaire (PSSUQ) also has excellent internal consistency, with an overall coefficient alpha of 97 Preliminary principal factor analysis of 48 PSSUQ questionnaires suggested the presence of

Electronic survey methodology: A case study in reaching hard-to-involve internet users.

Abstract: Using the Internet to conduct quantitative research presents challenges not found in conventional research. Paper-based survey quality criteria cannot be completely adapted to electronic formats. Electronic surveys have distinctive technological, demographic, and response characteristics that affect their design, use, and implementation. Survey design, participant privacy and confidentiality, sampling and subject solicitation, distribution methods and response rates, and survey piloting are critical methodological components that must be addressed. In this article, quality criteria for electronic survey design and use based on an investigation of recent electronic survey literature are presented. The application of these criteria to reach a hard-to-involve online population-nonpublic participants of online communities (also known as "lurkers")-and survey them on their community participation, a topic not salient to the purpose of their online communities is demonstrated in a case study. The results show t...

Investigating the Importance of Trust on Adopting an Autonomous Vehicle

Abstract: The objective of this study is to examine the user’s adoption aspects of autonomous vehicle, as well as to investigate what factors drive people to trust an autonomous vehicle. A model explaining the impact of different factors on autonomous vehicles’ intention is developed based on the technology acceptance model and trust theory. A survey of 552 drivers was conducted and the results were analyzed using partial least squares. The results demonstrated that perceived usefulness and trust are major important determinants of intention to use autonomous vehicles. The results also show that three constructs—system transparency, technical competence, and situation management—have a positive effect on trust. The study identified that trust has a negative effect on perceived risk. Among the driving-related personality traits, locus of control has significant effects on behavioral intention, whereas sensation seeking did not. This study investigated that the developed model explains the factors that influence the ...

Challenges, Methodologies, and Issues in the Usability Testing of Mobile Applications

Abstract: Usability testing of software applications developed for mobile devices is an emerging research area that faces a variety of challenges due to unique features of mobile devices, limited bandwidth, unreliability of wireless networks, as well as changing context (environmental factors) Traditional guidelines and methods used in usability testing of desktop applications may not be directly applicable to a mobile environment Therefore, it is essential to develop and adopt appropriate research methodologies that can evaluate the usability of mobile applications The contribution of this article is to propose a generic framework for conducting usability tests for mobile applications through discussing research questions, methodologies, and usability attributes The article provides an overview of existing mobil application usability studies and discusses major research questions that have been investigated Then, it proposes a generic framework and provides detailed guidelines on how to conduct such usability
