The aim of this study was to determine the support and information needs of older and disabled older people in the UK. Following an initial literature survey, an examination of data on enquiries made by older people to information providers, and a series of focus groups, a questionnaire was developed for a nationwide survey. Over 1630 questionnaires were completed by disabled older clients of Day Care Centres and less frail older members of social clubs. Findings showed that there is a serious shortfall in the number of older people getting the practical support that they need, and the information that enables access to this support, compared to the number that actually need help. Substantial percentages of the survey respondents experienced difficulty with everyday tasks and with accessing the information they needed. Implications for formal sources of support and information are discussed. 相似文献

The UK Government strategy for aging in the 21st Century challenges conceptions of older people as passive recipients of care and promotes their engagement as active citizens. The strategy includes a commitment to test services which embody these principles with a range of innovative pilot projects. This paper summarises research on older people’s information needs and use which informed the design for one of these projects, Leeds Link-Age Plus. The research explored the complex circumstances around which older people access and use social and community information – a topic that has received limited attention in the literature. The paper is novel in considering how the use of informal networks for securing information, advice and advocacy can be supported by technology literate mediators, who may be older people, located within local community or voluntary organisations. Emphasising the mediator in design facilitates social contacts, directly addresses issues of trust and can reduce the chance of causing distress dealing with complex information. A model is suggested for using emerging technology to introduce new ways in which information for older adults can be improved by digital ‘circles of support’ – a form of social network where mediators collaborate to create and share self-authored content. 相似文献

ContextFor more than four decades it has been intuitively accepted that user involvement (UI) during system development lifecycle leads to system success. However when the researchers have evaluated the user involvement and system success (UI-SS) relationship empirically, the results were not always positive.ObjectiveOur objective was to explore the UI-SS relationship by synthesizing the results of all the studies that have empirically investigated this complex phenomenon.MethodWe performed a Systematic Literature Review (SLR) following the steps provided in the guidelines of Evidence Based Software Engineering. From the resulting studies we extracted data to answer our 9 research questions related to the UI-SS relationship, identification of users, perspectives of UI, benefits, problems and challenges of UI, degree and level of UI, relevance of stages of software development lifecycle (SDLC) and the research method employed on the UI-SS relationship.ResultsOur systematic review resulted in selecting 87 empirical studies published during the period 1980–2012. Among 87 studies reviewed, 52 reported that UI positively contributes to system success, 12 suggested a negative contribution and 23 were uncertain. The UI-SS relationship is neither direct nor binary, and there are various confounding factors that play their role. The identification of users, their degree/level of involvement, stage of SDLC for UI, and choice of research method have been claimed to have impact on the UI-SS relationship. However, there is not sufficient empirical evidence available to support these claims.ConclusionOur results have revealed that UI does contribute positively to system success. But it is a double edged sword and if not managed carefully it may cause more problems than benefits. Based on the analysis of 87 studies, we were able to identify factors for effective management of UI alluding to the causes for inconsistency in the results of published literature. 相似文献

Many firms have implemented enterprise resource planning (ERP) systems in the past few years. The expensive nature of these systems requires that effective usage of these systems be attained in order for an organization to derive the expected benefits from the technology. This study looks at the influence that perceived usefulness, user involvement, argument for change, prior usage and ease of use have on the behavioral intention to use an ERP system. A mail survey was used to collect data in an organization that was implementing an ERP system. A total of 571 responses were obtained. The results indicate that users perception of the perceived usefulness, ease of use of the technology, and the users’ level of intrinsic involvement all affect their intention to use the technology. The results seem to suggest that managerial efforts aimed at increasing the users’ perceptions of the usefulness and personal relevance of the technology will contribute to implementation success, where success is defined as effectual usage of the technology. The paper ends with possible extensions to this study. 相似文献

Based on a 3-year ethnographical study, this paper discusses the prolonged use of computer-mediated communication (CMC) tools by approximately 400 older people in an adult education centre in Barcelona (Spain). Contrary to oversimplified views of older people as ICT users, this paper shows that they make a very rich use of CMC tools. Relevant elements of this use are their permanent desire to feel and be included, social, independent and competent ICT users. Despite the numerous interaction issues they face when using ICT, some are constant across different tools. Difficulties due to cognition limit their interactions more severely than those problems due to perceiving visual information or using the mouse. By examining the longitudinal aspect of the study, this paper addresses the evolution of technology use and whether the interaction issues that most of the current older people exhibit will be relevant when today’s more ICT literate young adults grow older. Interaction issues due to cognition are time-persistent, and independent of both experience and practice with ICT. Difficulties reading from the screen or using input devices are overcome with ICT experience. The strategies adopted by older people for coping with all these interaction issues are always targeted at feeling and being included, social, independent and competent ICT users. The results deepen current understanding of tools use in connecting older people with their social circles and the interaction issues most of them encounter when using ICT. The results also suggest that cognitive-related problems will be the most important ones in our work with the next generation of older people. 相似文献

User involvement has been shown to be beneficial in the development of useful and usable systems. The trend of software development becoming a product-oriented activity creates challenges to user involvement. Field studies appear a promising approach, but the analysis of the gathered user needs has been shown to be demanding. This study presents, on the basis of seven case studies, an early user-involvement process showing how user needs can be analysed and how the input to product development can be identified. In addition, the process is evaluated in two industrial cases with interviews and a questionnaire. The results show that the process supports effective early user involvement; the resulted requirements were evaluated as being more successful and their quality as better than average in a company. However, the case studies show that user involvement not only provides useful information about users' needs but also increases the understanding of users' values. 相似文献

HCI research has come of age, and now is a good time to reflect upon the HCI research processes that have become established over the years. This paper examines the HCI research process itself with respect to funding opportunities and the methods used for empirical research, assessing in particular the efficacy of standard methods for research dissemination. The focus of the paper is HCI research for older people. The nature of this user group is explored, and Alexandrian patterns are proposed both as a means of dissemination of research results and for strengthening the framework of HCI knowledge. 相似文献

Internet use and non-use: views of older users 总被引:1,自引:0,他引:1
This paper reports the results of two connected surveys of computer and Internet use among the older population in the UK.
One hundred and twenty questionnaires and interviews were completed with participants aged over 55 in Derbyshire and 353 questionnaires
and interviews with over 50s in Scotland. Rates of use, computer and Internet activities, and reasons for use and non-use
were investigated. These were backed up by four semi-structured interviews with IT trainers, describing experiences and issues
of training this age group. The results indicate a “grey” digital divide, with many older people missing out on the benefits
that computers and the Internet can provide. They also indicate some of the reasons why older people do not use computers
and the Internet more. These suggest some practical ways forward, highlighting the importance of changing older people’s misconceptions
about computers, better informing them about what they are, what they can do and how they can be of real practical use.

This paper documents how methodological challenges were addressed when identifying user requirements for an Interactive Domestic Alarm System (IDAS) designed to enable older adults to live independently in their own homes for longer. A novel approach to determine possible IDAS functionality is described, and the results of focus groups conducted with older adults and care workers are reported. The paper identifies some difficulties encountered when using the focus group method with an ageing sample, and highlights the importance of careful preparatory work if this method is to be used successfully in such a context. 相似文献

Context
User participation in information system (IS) development has received much research attention. However, prior empirical research regarding the effect of user participation on IS success is inconclusive. This might be because previous studies overlook the effect of the particular components of user participation and other possible mediating factors.Objective
The objective of this study is to empirically examine how user influence and user responsibility affect IS project performance. We inspect whether user influence and user responsibility improve the quality of the IS development process and in turn leads to project success, or if they have a direct positive influence on project success.Method
We conducted a survey of 151 IS project managers in order to understand the impact of user influence and user responsibility on IS project performance. Regression analysis was conducted to assess the relationship among user influence, user responsibility, organizational technology learning, project control, user-developer interaction, and IS project management performance.Results
This study shows that user responsibility and user influence have a positive effect on project performance through the promotion of IS development processes as mediators, including organizational technology learning, project control, and user-IS interaction.Conclusion
Our results suggest that user responsibility and user influence respectively play an important role in indirectly and directly impacting project management performance. Results of the analysis imply that organizations and project managers should use both user participation and user influence to improve processes performance, and in turn, increase project success. 相似文献11.
Understanding processes underlying technology adoption or non-adoption is an important research theme often addressed using the technology acceptance model (TAM) approach. The objective of this research was to investigate most influential user experiences in successful and unsuccessful technology adoptions using user experience related concepts and methods in conjunction with the TAM. Participants (N = 76) described their most influential user experiences related to one successful and one unsuccessful technology adoption process and evaluated both experiences using rating scales, including the central TAM related scales and user experience related scales probing emotions, psychological needs, user values, task load, and the impact of technology on the user’s well-being.The results suggested that user experience and technology acceptance related viewpoints can complement each other in order to gain a more holistic understanding of the factors affecting the success or failure of technology adoptions, and the results showed how these variables typically behave in both contexts. The overall valence of user experience was significantly affected by perceived usefulness, the fulfillment of psychological needs, and the salience of negative emotions in the most influential user experiences of successful adoptions, and by perceived usefulness, output quality, and the salience of negative emotions in the unsuccessful adoptions. 相似文献

This paper describes the investigation of the development of future technological products to support older people in everyday
living through the agency of a community art group. Recent research has identified a number of challenges facing designers
seeking to use traditional participatory design approaches to gather technology requirements data from older people. Here,
a project is described that sought to get a group of older people to think creatively about their needs and desires for technological
support through the medium of paint. The artistic expression technique described in this article allowed the identification
of issues that had also been found by previous research that used a range of different techniques. This indicates that the
approach shows promise, as it allows information to be gathered in an environment that is comfortable and familiar using methods
already known by the participants and which they find enjoyable. It provides a complement (or possible alternative) to standard
protocols and has the potential benefit of extracting even richer information as the primary task for participants is enjoyable
in its own right and is not associated with an interrogative process. Furthermore, it is argued that some of the key risks
of traditional approaches are lessened or removed by the naturalistic setting of this approach.

Executives responsible for the information system function need to be concerned about developing a base of satisfied users and maintaining continuing user satisfaction after implementation. This article focuses on user satisfaction among on-going user manager, explores the role of good user documentation, and examines the results of a survey of 144 user managers from 55 firms. The results indicate that good user documentation appears to be an important factor in insuring user understanding and continuing user satisfaction. Thus firms considering alternative ways of keeping users satisfied (i.e., personal computer applications, end user computing, or information centers) might well examine their user documentation practices before exploring other alternatives. 相似文献

3D online multi-user virtual environments (MUVEs) have a lot of potential in supporting older people in their daily lives, yet little research has been conducted to explore how older people engage with this type of technology. This paper aims to investigate the characteristics, user groups and activity patterns (particularly social networks and gift giving behaviour) of older users within a 3D online multi-user virtual environment. Data from approximately 5000 online user profiles of older and younger users from a 3D MUVE, namely IMVU, was collected for analysis. Overall, we identified several distinct patterns of use (e.g. size of social ties, level of reciprocity, etc.) among older users when compared with younger users. We also found that despite the capabilities of 3D MUVEs to provide the users immersion in alternative realities, a feature well embraced by younger users in this study, older users seemed more interested in activities which serve as an extension to their physical life. 相似文献

The significant changes in the social, legal, demographic, and economic landscape over the past 10–15 years present enormous
opportunities for the human–computer interface design community. These changes will have a significant impact on the design
and development of systems for older and disabled people. This paper brings together a number of proposals to improve both
specialist and mainstream design methods in the field as a contribution to the debate about design for older and disabled
people and the concept of universal usability.

Experimental research in human - computer interaction commonly uses participant groups that are unrepresentative of demographic realities, being young, technically knowledgeable and highly educated. One way of reflecting society more accurately in research is to include older adults in research groups, but the elicitation of high-quality data from these participants requires alterations in research methods and organization. In the present paper, methodological and organizational experiences from a range of research studies with older participants are reported. It concludes with a list of guidelines for maximizing the research outcomes of working with older adults. 相似文献

Previous research has shown loneliness as a threat for the quality of life of older people; therefore the goal of the intervention in a quasi-experimental study was to evaluate and discuss the self-reported level of loneliness of older people in Finland and Slovenia before and after a computer intervention. Intervention in a quasi-experimental study was conducted among 58 older participants at the baseline (M = 72.4 years) and 45 older participants at the follow-up research study (M = 72.9 years). Inferential statistics showed a significant difference in the reduction of loneliness between the countries, and a decreased level of loneliness of older people after completing the computer training course. Although older people experience many age-related problems which may reduce their interest in learning information and communication technology (ICT) skills, it is important that they are computer-proficient, because computer engagement can reduce the level of loneliness of older people and in this way has a positive effect on their quality of life. 相似文献

In this paper, we study the social network structure of an online discussion board within SeniorNet, an empathic online community for older people. We apply Social Network Analysis (SNA) to analyse the communication patterns and relationships between members of the discussion board. In addition to looking at the structure of the exchanged messages within the discussion board as a whole, we also investigate associations between the communication content and the social network patterns. Our findings show distinct differences between the social network patterns of empathic and non-empathic communications. For example, members are more connected and closer to each other in the social networks that are based on empathic communication compared to non-empathic communication. Additionally our results show that the type of empathic communication (e.g. different kinds of support) is linked to the social network structure within the discussion board. 相似文献

Business intelligence (BI) is a powerful tool to conduct causality analysis and corporate diagnoses since it provides a data-driven approach to link firms' strategic goals into tactical policies and operational actions. Specifically, BI consists of a series of architectures and techniques like database, data warehousing, and data mining that transform raw data into useful information to provide decision supports. In reality, typical BI user groups involve financial analysts, marketing planners, general managers, field staffs, upstream suppliers, and downstream customers. Inspired by the concept of STP (segmentation-target-positioning) and product family design, BI systems need to be customized to satisfy diverse user groups and tailored to a firm for solving complicated but specific business problems. Consequently, a novel framework is proposed to fulfill the following goals: (1) incorporating user preferences to identify key design features that best fit BI's main segments for achieving customer acquisition, (2) transforming user perceptions into quantitative degrees of satisfaction for accomplishing customer retention, and (3) conducting the importance-satisfaction analysis to generate managerial insights for developing next-generation BI systems. 相似文献
