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. 相似文献

This study has been performed in order to evaluate a prototype for the human - computer interface of a computer-based speech training aid named ARTUR. The main feature of the aid is that it can give suggestions on how to improve articulations. Two user groups were involved: three children aged 9 - 14 with extensive experience of speech training with therapists and computers, and three children aged 6, with little or no prior experience of computer-based speech training. All children had general language disorders. The study indicates that the present interface is usable without prior training or instructions, even for the younger children, but that more motivational factors should be introduced. The granularity of the mesh that classifies mispronunciations was satisfactory, but the flexibility and level of detail of the feedback should be developed further. 相似文献

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. 相似文献

In this study we examined the influence of attitude strength on the processing and evaluation of sources and information on the Web. Seventy-nine German university students participated in an eye-tracking study in which they read information from eight pre-selected websites from different sources on the controversial topic of organic foods. Results showed that participants who felt strongly about the topic (i.e., those with strong prior attitude strength) scrutinized website logos of attitude-inconsistent websites shorter and judged the credibility of attitude-inconsistent websites lower. They also included more attitude-consistent information in an essay task than participants with weaker prior attitudes. Participants who felt less strongly about the topic (i.e., those with weaker prior attitudes) fixated longer on text from attitude-inconsistent websites than from attitude-consistent websites. By contrast, for participants with strong prior attitudes the time spent on the texts from attitude-consistent websites and attitude-inconsistent websites did not differ significantly. The results show that prior attitudes can bias evaluation and processing of information in different ways. Even though participants were not fully biased during initial information processing, they were so when evaluating the information and presenting it in an essay task. 相似文献

Compared to the Internet, mobile telecommunication has the characteristics of being anywhere, anytime and always online. As the growth of the Internet advertisements market slows down, there is a substantial increase in mobile advertisements. This research investigates the effectiveness of the presentation (static text and graphics, static text and graphics with audio, and animation) of mobile advertisements on the recognition of advertisements. The two types of websites for mobile advertisements - entertainment information and location-based information - are also compared. An experiment was carried out to test the proposed hypotheses. The results show that the effects of static banners with audio mobile advertisement, and animation mobile advertisement were better than static banners in advertisement recognition and memorisation. The participants of websites providing location-based information had higher advertisement attitude and purchase intention than their web-based counterparts providing entertainment information. 相似文献

The website has been greatly extended and is popular all over the world for electronic commerce. Many technical tools and business functions can increase their reach by websites. The mobile phone service is an essential amenity for people. The intention of this research is to take an extensive look at different kinds of mobile phone website users. In this research, Q methodology is used to gather and analyze the data. According to the results, users’ types may be categorized into four groups: Online shoppers, Information seekers, Recreation demanders, and Easy users. The empirical results of this study can provide decision support intelligence for the websites designers to increase mobile phone website users’ satisfaction. 相似文献

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. 相似文献

This paper presents an integrative framework to evaluate ecommerce website efficiency from the user viewpoint using Data Envelopment Analysis (DEA). This framework is inspired by concepts driven from theories of information processing and cognition and considers the website efficiency as a measure of its quality and performance. When the users interact with the website interfaces to perform a task, they are involved in a cognitive effort, sustaining a cognitive cost to search, interpret and process information, and experiencing either a sense of satisfaction or dissatisfaction for that. The amount of ambiguity and uncertainty, and the search (over-)time during navigation that they perceive determine the effort size – and, as a consequence, the cognitive cost amount – they have to bear to perform their task. On the contrary, task performing and result achievement provide the users with cognitive benefits, making interaction with the website potentially attractive, satisfying, and useful. In total, 9 variables are measured, classified in a set of 3 website macro-dimensions (user experience, site navigability and structure). The framework is implemented to compare 52 ecommerce websites that sell products in the information technology and media market. A stepwise regression is performed to assess the influence of cognitive costs and benefits that mostly affect website efficiency. 相似文献

Two studies are presented. The first aimed to identify possible barriers to the uptake and use of commonly available telephony features and to determine whether greater knowledge of features/access codes and availability of user manuals could increase feature usage under certain conditions. Results showed that feature-usage patterns were not affected by any of the manipulations, but that they were determined by specific job demands. Using Constantine and Lockwood's (1999) conceptualization of user roles, a method to support feature bundling decisions for specific target markets was developed and tested in the second study. The method - Strategic User Needs Analysis (SUNA) - was shown to yield a useful balance between high- and low-level information about selected roles. SUNA provided sufficient information to distinguish between PDA feature usage patterns of two similar target user groups as well as to suggest additional features each of the two target groups would find useful. The development of SUNA and observational findings of actual PDA usage are reported. 相似文献

A detailed model specifying the linkages between Internet recruitment websites and organizational attraction was examined. Participants ( N = 581) viewed Fortune 500 company websites and responded to questions about the content and design of these websites and their resulting attitudes, fit perceptions, and organizational attraction. Results showed that recruitment website content and design influence attitudes toward the recruitment websites, organizational attitudes, and subsequently organizational attraction. The moderating effects of person-organization (P-O) and person-job (P-J) fit were examined. Two sets of hypotheses based on signaling theory ( and ) and the elaboration likelihood model ( Petty & Cacioppo, 1981) were largely supported. Consistent with signaling theory, the amount of job and organizational information on a recruitment website interacted with website usability, such that when less job information was presented, website usability played a greater role in predicting favorable attitudes towards the organization. Consistent with the elaboration likelihood model, when P-J fit was high, website aesthetics were less important in predicting attitudes towards the organization. 相似文献

Trust and privacy features of websites have evolved as an important concern for any businesses or interactions, particularly in online networks. The study investigates the relationship between trust, privacy concerns and behavioural intention of users on the social network. The behavioural intention of users on the online social network (OSN) is captured by intention to disclose information and intention to interact with others in OSN. The study was conducted on a sample of 457 active users from one of the major social networking website, Facebook. Partial least squares based structural equation modelling was used for analysing the results. The findings of the study reveal that intention to disclose information mediates the relationship between trust in the website and the intention to interact with others. Another important finding of the study indicates that prior positive experience with the website significantly impacts the trust in website, and the trust in website also plays a crucial role while determining the information privacy concerns in the OSN. 相似文献

This study investigates the cognitive strategies of 80 participants as they engaged in two researcher-defined tasks and two participant-defined information-seeking tasks using the WWW. Each researcher-defined task and participant-defined task was further divided into a directed search task and a general-purpose browsing task. On the basis of retrospective verbal protocols, log-file data and observations, 12 cognitive search strategies were identified and explained. The differences in cognitive search strategy choice between researcher-defined and participant-defined tasks and between directed search and general-purpose tasks were examined using correspondence analysis. These cognitive search strategies were compared to earlier investigations of search strategies on the WWW. Relevance to industryDescribing information-seeking behaviours and cognitive search strategies in detail provides website developers and search engine developers with valuable insights into how users seek (and find) information of value to them. Using this information, website developers might gain some knowledge as to how to best represent the content and navigational properties of websites. Search engine developers might wish to make the search and collection strategies more transparent to users. There are also design implications for the designers of web browsers. 相似文献

Studies on health domain have shown that health websites provide imperfect information and give recommendations which are not up to date with the recent literature even when their last modified dates are quite recent. In this paper, we propose a framework which assesses the timeliness of the content of health websites automatically by evidence based medicine. Our aim is to assess the accordance of website contents with the current literature and information timeliness disregarding the update time stated on the websites. 相似文献

Despite the rapidly increasing numbers of informational websites and learners using the World Wide Web to research topics, empirical evidence on the relationships between website design elements and website trustworthiness is scarce. This study used self-reported and behavioral screen-capture data to investigate the impact of Don Norman's (2003) emotional design levels and metacognitive awareness on website trustworthiness during an information search learning task. The results suggest that the interaction effects of website visual appeal (visceral level) and website usability (behavioral level) can override the effects of the quality or relevance of the information (reflective level) on website evaluation. In addition, in the context of limited time to find the answers, these effects on the evaluation of website trustworthiness are not moderated by users’ metacognitive awareness. 相似文献

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. 相似文献

OBJECTIVE: The present study examined Web-based information retrieval as a function of age for two information organization schemes: hierarchical organization and one organized around tags or keywords. BACKGROUND: Older adults' performance in information retrieval tasks has traditionally been lower compared with younger adults'. The current study examined the degree to which information organization moderated age-related performance differences on an information retrieval task. The theory of fluid and crystallized intelligence may provide insight into different kinds of information architectures that may reduce age-related differences in computer-based information retrieval performance. METHOD: Fifty younger (18-23 years of age) and 50 older (55-76 years of age) participants browsed a Web site for answers to specific questions. Half of the participants browsed the hierarchically organized system (taxonomy), which maintained a one-to-one relationship between menu link and page, whereas the other half browsed the tag-based interface, with a many-to-one relationship between menu and page. This difference was expected to interact with age-related differences in fluid and crystallized intelligence. RESULTS: Age-related differences in information retrieval performance persisted; however, a tag-based retrieval interface reduced age-related differences, as compared with a taxonomical interface. CONCLUSION: Cognitive aging theory can lead to interface interventions that reduce age-related differences in performance with technology. In an information retrieval paradigm, older adults may be able to leverage their increased crystallized intelligence to offset fluid intelligence declines in a computer-based information search task. APPLICATION: More research is necessary, but the results suggest that information retrieval interfaces organized around keywords may reduce age-related differences in performance. 相似文献

Visual complexity is an apparent feature in website design yet its effects on cognitive and emotional processing are not well understood. The current study examined website complexity within the framework of aesthetic theory and psychophysiological research on cognition and emotion. We hypothesized that increasing the complexity of websites would have a detrimental cognitive and emotional impact on users. In a passive viewing task (PVT) 36 website screenshots differing in their degree of complexity (operationalized by JPEG file size; correlation with complexity ratings in a preliminary study r=.80) were presented to 48 participants in randomized order. Additionally, a standardized visual search task (VST) assessing reaction times, and a one-week-delayed recognition task on these websites were conducted and participants rated all websites for arousal and valence. Psychophysiological responses were assessed during the PVT and VST. Visual complexity was related to increased experienced arousal, more negative valence appraisal, decreased heart rate, and increased facial muscle tension (musculus corrugator). Visual complexity resulted in increased reaction times in the VST and decreased recognition rates. Reaction times in the VST were related to increases in heart rate and electrodermal activity. These findings demonstrate that visual complexity of websites has multiple effects on human cognition and emotion, including experienced pleasure and arousal, facial expression, autonomic nervous system activation, task performance, and memory. It should thus be considered an important factor in website design. 相似文献

The interface is the major channel through which users to navigate a website to find information matching their needs; nevertheless, gender-specific preferences for websites interface design have not been sufficiently explored or evaluated based on comprehensive and systematic approaches in past research. This study investigated the website interface design criteria for users of different genders based on usability principles. Undergraduate and graduate students in Taiwan were selected as the target sample. A total of 236 valid questionnaires were analyzed. The results showed significant gender differences in scaling of the importance of website interface design criteria. The three most important website interface design criteria for males were compatibility, minimal action, and flexibility, whereas the three most important design criteria for females were compatibility, learnability, and user guidance. This paper discusses the possible explanations for the gender differences and their implications for website design. 相似文献

The internet is a prominent source of health information for the public. This research evaluated both basic use and design tenets and the presence of theoretical components to motivate healthy breast cancer behavior for users of the most frequented breast cancer websites. Methodology : Each website was evaluated with 2 sets of questions. The first attends to the basic use and design tenets of the website. The second coding form assessed the websites use of 3 behavior change theories. Results : The majority of the websites fared well with regards to their use of basic tenet and design principles. Theoretical components were used sparingly on the majority of websites. Discussion : The most frequented breast cancer websites are currently well equipped with basic use and design tenets. However, their lack of behavioral change components is likely to impede users’ motivations to protect themselves against breast cancer. 相似文献
