Crucial web usability factors of 36 industries for students: a large-scale empirical study

The study identifies and prioritizes the crucial Web Usability Factors (WUFs) for websites from 36 industries. 400 respondents participated in the web evaluation and more than 12,000 data points were collected and analyzed using Multiple Linear Regression. Seven WUFs were tested, i.e. Use of Color and Font, Use of Graphics and Multimedia, Clarity of Goals in Website, Trustworthiness of Website, Interactivity of Website, Ease of Web Navigation, and Downloading Speed of Website. Results reveal that every industry has a different set of crucial WUFs. The research compared and discussed its results with previous studies such as Agarwal and Venkatesh (Inf. Syst. Res. 13:168–186, 2002). Moreover, students’ preference for Web usability was compared with that of general Internet users. The study provides a simple method to measure web usability and to determine which WUFs are important for a specific industry with consideration of the users’ role. Practitioners can use the results as a guide to design usable websites for specific industry. This study is the first that comprehensively examines the WUFs of students by employing a very large sample size across various industries, thus yielding more specific and meaningful results.     

The negative impact of saturation on website trustworthiness and appeal: A temporal model of aesthetic website perception

Previous research on the perception of websites has shown that users' impressions of websites generated in ultra-rapid display durations (50 ms) correlate with their assessment after longer display durations. Based on the importance of color saturation in the design of websites, we present a 2 ✕ 3 ✕10 study design in which participants either assessed highly saturated or desaturated versions (between-subjects) of 50 websites coming from 10 content domains. All websites were presented three times to each participant in varying durations (50 ms, 500 ms, and 10 s), and each site was rated regarding its trustworthiness, visual appeal, and perceived usability. In contrast to a large body of research describing positive effects of higher saturated colors, our results show that these findings cannot be generalized to website perception, as we found negative effects of saturation depending on the content domain. Furthermore, we propose a temporal model of website perception based on the results in which users first evaluate the visual appeal of a website, followed by a continuous re-assessment of apparent usability, and lastly its trustworthiness. The results have broad implications for the design and presentation of information using digital media.     

A quality evaluation methodology for health-related websites based on a 2-tuple fuzzy linguistic approach

Nowadays, the patients and physicians use the health-related websites as an important information source and, therefore, it is critical the quality evaluation of health- related websites. The quality assessment of health-related websites becomes especially relevant because their use imply the existence of a wide range of threats which can affect people’s health. Additionally, website quality evaluation can also contribute to maximize the exploitation of invested resources by organizations in the development of user-perceived quality websites. But there is not yet a clear and unambiguous definition of the concept of website quality and the debate about quality evaluation on the Web remains open. In this paper, we present a qualitative and user-oriented methodology for assessing quality of health-related websites based on a 2-tuple fuzzy linguistic approach. To identify the quality criteria set, a qualitative research has been carried out using the focus groups technique. The measurement method generates linguistic quality assessments considering the visitors’ judgements with respect to those quality criteria. The combination of the linguistic judgements is implemented without a loss of information by applying a 2-tuple linguistic weighted average operator. This methodology means an improvement on quality evaluation of health websites through the commitment to put users first.

Website design attributes for retrieving health information by older adults: an application of architectural criteria

The objectives of this research were to identify design attributes to develop easy-to-use websites for older adults. Forty-one males and 58 females (age range 58–90) were asked to retrieve information on a health-related topic from the NHS Direct and Medicdirect websites, and were asked to fill in a website evaluation questionnaire. An exploratory factor analysis of data identified navigation/search usability, link usability, usefulness and colour as important dimensions of a senior-friendly website. A two-stage, three-component regression model with these dimensions as predictor variables and the satisfaction level in using a website as the dependent variable has been proposed.     

Evaluating websites for older adults: adherence to ‘senior-friendly’ guidelines and end-user performance

Older adults in the US are the fastest-growing demographic, and also the largest-growing group of internet users. The aim of this research was to evaluate websites designed for older adults in terms of (i) how well they adhere to ‘senior-friendly’ guidelines and (ii) overall ease of use and satisfaction. In Experiment I, 40 websites designed for older adults were heuristically evaluated based on their adherence to usability guidelines derived by the National Institute on Aging and the National Library of Medicine. In Experiment II, three websites with varying levels of guideline compliance were evaluated by older adults in a usability test. Results from this study indicate that the website most compliant with the ‘senior-friendly’ guidelines resulted in higher task success, but did not result in significantly better efficiency, satisfaction, or preference. These findings demonstrate the importance of using both guidelines and usability testing when designing websites for older adults.     

Effective website design for experience-influenced environments: The case of high culture museums

While most research on website has focused on functional tasks, the Internet offers many opportunities for leisure as well as experiential activities. Because of the evolution of developed society toward an experience economy, analyzing the role of technologies in the presence of prior user experiences makes sense. This research identifies variables that play a role and influence online behaviors in a specific experiential environment, namely the high culture museum website. Relying on the literature on experience, we propose a research model tested with two different websites. The results of the free simulation experiment indicates that (1) esthetics is the most important design criteria for experiential interfaces and (2) that website design influences intentions to visit a physical place.     

E-commerce success criteria: determining which criteria count most

We explore in this paper how performance of e-commerce websites in terms of various criteria influences customers’ intention to shop again in the same website. Our approach is based on an interesting use of statistical regression in the hotel literature that attempted to classify different cues in hotels as critical, satisfier, dissatisfier, etc. We use online ratings for 484 e-commerce websites for this study. Our study shows that “satisfaction with claims” is the single most important criterion valued as critical by online customers. “Comparative prices” and “Refunds/returns” are desirable criteria. “Management accessibility”, “Payment process” and “Privacy experience” are satisfiers while “on-time delivery” is a dissatisfier.     

High and low spatial frequencies in website evaluations

Statement of Relevance:

Which features of websites are important for users' perceptions regarding aesthetics or usability? This study investigates how evaluations of aesthetic appeal and usability depend on high vs. low spatial frequencies. High spatial frequencies convey information on fine details, whereas low spatial frequencies convey information about the global layout. Participants rated aesthetic appeal and usability of 50 website screenshots from different domains. Screenshots were presented unfiltered, low-pass filtered with blurred targets or high-pass filtered with high-pass filtered targets. The main result is that low spatial frequencies can be seen to have a unique contribution in perceived website aesthetics, thus confirming a central prediction from processing fluency theory. There was no connection between low spatial frequencies and usability evaluations, whereas strong correlations were found between ratings of high-pass filtered websites and those of unfiltered websites in aesthetics and usability. This study thus offers a new perspective on the biological basis of users' website perceptions.

This research links ergonomics to neurocognitive models of visual processing. This paper investigates how high and low spatial frequencies, which are neurologically processed in different visual pathways, independently contribute to users' perceptions of websites. This is very relevant for theories of website perceptions and for practitioners of web design.     

Website success comparison in the context of e-recruitment: An analytic network process (ANP) approach

This study investigates relative importance of website success factors in selecting the most preferred website. To identify relative importance of website success factors and to rank alternative websites with respect to success factors, Updated Delone and McLean Information System Success Model is extended through applying an analytic network process (ANP) approach. A field study with 383 academic internet users was performed. Relative importance of each website success factor with respect to their influence on using the e-recruitment website, and user satisfaction are identified. Furthermore relative significance of using the e-recruitment website and user satisfaction in achieving positive benefits are discovered. This study also found the relative preference of each website with respect to different success variable.Results indicate that ANP is an effective tool to provide an accurate solution for interdependencies that are able to affect the decision to be made for network like models. The findings of this study provide decision makers of e-commerce companies with useful insights to compare the preference of their website with others with respect to different success variables. Moreover, relative significance of different success variables in websites can be compared.     

Has Web 2.0 revitalized informal learning? The relationship between Web 2.0 and informal learning

Learning is becoming increasingly self‐directed and often occurs away from schools and other formal educational settings. The development of a myriad of new technologies for learning has enabled people to learn anywhere and anytime. Web 2.0 technology allows researchers to shed a new light on the importance and prevalence of informal learning. However, there are few empirical studies that support the claim that this technology facilitates informal learning. The present study investigates the relationship between Web 2.0 levels and the evaluation of informal learning websites. For this purpose, 287 informal learning websites were selected and their Web 2.0 levels were rated based upon eight criteria proposed in the Web 2.0 exploratory literature. In addition, previously examined informal learning evaluation results were employed. The results showed that current informal learning websites have moderately adopted the most heavily promoted features of Web 2.0. Correlation analyses showed a positive relationship between Web 2.0 features and informal learning website ratings. The implications for the relationship and internal correlations of variables were summarized and discussed.     

Interface design and emotions experienced on B2C Web sites: Empirical testing of a research model

This paper examines the impact of four Web site interface features on the cognitive process that trigger online shoppers’ emotions, operationalized as mental states of readiness that arise from appraisal of events and considered as direct antecedents to approach or avoidance behaviors. A research model was tested with data collected from 215 Web shopping episodes for low-touch merchandise. Results show that shoppers experienced all six emotions posited in the model. The emotions of liking and joy were experienced intensively by a substantial number of shoppers. The results also demonstrate that interface features – key components of the usability of a Web site – influenced the three cognitive appraisals illustrated in the research model. Moreover, the cognitive appraisals of situational state and control potential impacted the six emotions examined. This paper also highlights several theoretical contributions and managerial implications that should help managers and Web site managers improve the interface design of their Web sites in order to facilitate information gathering and better support online shopping processes.

Expressive and classical aesthetics: two distinct concepts with highly similar effect patterns in user–artefact interaction

This study examined the utility of the concept of expressive aesthetics by testing websites that did or did not match this concept. A website scoring highly on this concept was created and was then compared to websites that were either non-aesthetic or corresponded to the concept of classical aesthetics. Sixty website users of a broad age range (18–60 years) were allocated to three experimental groups (expressive, classical, and non-aesthetic) and asked to complete a series of information search tasks. During the experiment, measures were taken of performance, perceived usability, perceived aesthetics, emotion, and trustworthiness. The results showed that expressive aesthetics can be considered a distinct concept. It also emerged that the website scoring high on expressive aesthetics shows a similar pattern of results to classical aesthetics. Both aesthetically appealing websites received higher ratings of perceived usability and trustworthiness than the non-aesthetic website. The effects of website aesthetics on subjective measures were not moderated by age.     

The Web Designer's Guide to Color Research

ABSTRACT

Color plays an integral role in the success or failure of a Web site. Unfortunately, many Web designers misuse this vital element by making color design decisions based solely on personal opinions, rather than on scientific evidence. This evidence shows that color affects the viewers' experiences of the Web site in terms of how the viewers learn information, how they perceive the site's readability and download speed, and how satisfied they are with the Web site overall. This article (1) discusses the basic elements of color: hue, saturation, and luminance, (2) investigates the physiological, psychological, and cultural research on color perception, and (3) provides recommendations for Web designers based on this research.     

Towards cultural translation of websites: a large-scale study of Australian,Chinese, and Saudi Arabian design preferences

Since websites are developed and maintained by different cultures, web page design may be influenced by the originating culture. This study examines the usage of design attributes between Australian, Chinese, and Saudi Arabian cultures. This study used automated and manual techniques to investigate design attributes including layout, navigation, links, multimedia, visual representation, colour, and text. Significant differences were found in each of the listed design attributes, suggesting that different interfaces may be needed for successful communication with different cultural groups. The results of this study confirm and extend prior research and anthropological models. The contribution of this study is the scale (460 websites in total) and breadth (seven design attributes) of the research. It also provides revised insights into culture and website design and the concept of cultural translation of web content.     

Truth Discovery with Multiple Conflicting Information Providers on the Web

The World Wide Web has become the most important information source for most of us. Unfortunately, there is no guarantee for the correctness of information on the Web. Moreover, different websites often provide conflicting information on a subject, such as different specifications for the same product. In this paper, we propose a new problem, called Veracity, i.e., conformity to truth, which studies how to find true facts from a large amount of conflicting information on many subjects that is provided by various websites. We design a general framework for the Veracity problem and invent an algorithm, called TRUTHFlNDER, which utilizes the relationships between websites and their information, i.e., a website is trustworthy if it provides many pieces of true information, and a piece of information is likely to be true if it is provided by many trustworthy websites. An iterative method is used to infer the trustworthiness of websites and the correctness of information from each other. Our experiments show that TRUTHFlNDER successfully finds true facts among conflicting information and identifies trustworthy websites better than the popular search engines.

Effects of accessible website design on nondisabled users: age and device as moderating factors

This study examined how implementing recommendations from Web accessibility guidelines affects nondisabled people in different age groups using different technical devices. While recent research showed positive effects of implementing such recommendations for nondisabled users, it remains unclear whether such effects would apply to different age groups and kind of devices. A 2 × 2 × 2 design was employed with website accessibility (high accessibility vs. very low accessibility), age (younger adults vs. older adults) and type of device (laptop vs. tablet) as independent variables. 110 nondisabled participants took part in a usability test, in which performance and satisfaction were measured as dependent variables. The results showed that higher accessibility increased task completion rate, task completion time and satisfaction ratings of nondisabled users. While user age did not have any effects, users showed faster task completion time under high accessibility when using a tablet rather than a laptop. The findings confirmed previous findings, which showed benefits of accessible websites for nondisabled users. These beneficial effects may now be generalised to a wide age range and across different devices.

Practitioner Summary: This work is relevant to the design of websites since it emphasises the need to consider the characteristics of different user groups. Accessible website design (aimed at users with disabilities) leads to benefits for nondisabled users across different ages. These findings provide further encouragement for practitioners to apply WCAG 2.0.     

Validating WCAG versions 1.0 and 2.0 through usability testing with disabled users

The Web Content Accessibility Guidelines (WCAG) by the Web Accessibility Initiative (WAI) has become the de-facto standard for accessibility on the Web. WCAG version 1.0 has become significant both as a practical tool and as an academic set of principles and is presently the basis of Web accessibility evaluations and guidelines in many countries. WCAG version 2.0 was released in 2008. This paper reports on a study that empirically validated the usefulness of using WCAG as a heuristic for website accessibility. Through controlled usability tests of two websites with disabled users (N?=?7) and a control group (N?=?6), it was found that only 27% of the identified website accessibility problems could have been identified through the use of WCAG 1.0. A similar analysis of conformance to WCAG 2.0 showed a marginal 5% improvement concerning identified website accessibility problems. Compensating for the low number of test subjects with confidence tests gave results that were still low (42% for WCAG 1.0 and 49% for WCAG 2.0, with 95% confidence). It is concluded from this that the application of WAI accessibility guidelines is not sufficient to guarantee website accessibility. It is recommended that future versions of the accessibility guidelines should be based on empirical data and validated empirically and that WAI expand their definition of accessibility to include “usability for all” in accordance with ISO 9241-171:2008.
