P2P context awareness based sensibility design recommendation using color and bio-signal analysis

In regards to information technology of modern society, IT convergence technology is applied in various fields. Particularly, active studies are conducted for creative design products with the use of IT convergence technology in design industry which transforms sensibility of people into various expressions. People started to put high significance to design elements and sensibility accordingly with diverse and distinctive lifestyle and active studies are also conducted on sensibility engineering interaction method which connects sensibility of people with design to satisfy such demand. Also, since distributed processing became available, advancement from server centered information processing and network, such strength is applied to design industry as well. The purpose of this study lies in recommending and proposing P2P context awareness based sensibility design using color and bio-signal analysis. In order to express design that coincides with distinctive and differentiated sensibility of people, the proposed method analyzes relation between visual sensibility and color design with the use of statistic analysis tool R 3.1.0 and SPSS 21.0 and the clustering of users with similar sensibility is conducted with the use of P2P network based context awareness. It recommends color design that coincides with the sensibility of new user by using the P2P network based collaborative filtering and applying it to color design based on clustered users. Proposed method reduces the time and cost spent to estimate design that satisfies the sensibility and requirement of user and supports companies to have concrete and clarified grasp on ambiguous personal requirement of user.     

The impact of aging on access to technology

The number of people over the age of 65 is increasing worldwide with the fastest growing subgroup those aged 80+ years. Computer and information technologies hold promise in terms of increasing the quality of life for older people. However, successful use of technology by older adults is predicated on systems that are designed to accommodate the needs and preferences of this user group. This paper discusses the implications of age-related changes in cognition for system design. Generally, the existing literature shows that, although older adults are willing to use technology, many report usability problems with existing systems and these problems may in part be due to the cognitive and perceptual demands placed on the user. These findings are discussed in terms of guidelines for system design.     

The effects of 3D interface metaphor on older adults’ mobile navigation performance and subjective evaluation

Navigating vast information spaces through mobile interfaces has become a common activity in older adults' everyday lives. Studies suggested that interface metaphors could be used to facilitate users' metal model development and information processing when using mobile technologies. However, we know little about how metaphors affect older adults' mobile navigation behavior, and which user characteristics matter during this perceptual and cognitive process. To investigate this, a card interface with a 3D metaphor and a list interface without 3D metaphors were compared among twenty-two participants when performing four navigation tasks. User characteristics including demographic factors, technology experience, and user capabilities were examined. The participants' navigation performance and subjective evaluations were measured as the dependent variables. From the results, we recommend the list interface without 3D metaphors as a beneficial choice for older adults. It performed better in navigation performance, although the differences are not statistically significant. Moreover, navigation performance using the card interface with a 3D metaphor was significantly associated with participants' perceptual speed, thus this interface may be more sensitive to capability declines. Valuable insights into the older adults’ mobile navigation performance and preferences are discussed and important implications for the design of mobile navigation user interfaces are proposed based on the results.Relevance to industryThe experimental results propose a more beneficial way to present contents on a mobile user interface for older adults and provide valuable insights for the designers and industry to help them understand the older adults’ usage and perceptions towards the application of 3D metaphors when navigating with mobile interfaces.     

Usability of geographic information – Factors identified from qualitative analysis of task-focused user interviews

Understanding user needs for geographic information and the factors which influence the usability of such information in diverse user contexts is an essential part of user centred development of information products. There is relatively little existing research focused on the design and usability of information products in general. This paper presents a research approach based on semi structured interviews with people working with geographic information on a day to day basis, to establish a reference base of qualitative data on user needs for geographic information with respect to context of use. From this reference data nine key categories of geographic information usability are identified and discussed in the context of limited existing research concerned with geographic information usability.

Design of a Mobile Social Community Platform for Older Chinese People in Urban Areas

The increasing proportion of the older population and changes in the Chinese family structure make older Chinese people more vulnerable to social isolation than they previously were. This article illustrates the development of a mobile social application for older people in urban areas in China. The application facilitates the organization of leisure‐time activities between older people with similar interests living in adjacent areas. Preliminary social requirements of older people were collected through user interviews, and the major functions and features for the application were determined from the results of the interviews. Usability considerations for user interface design for older people were collected from literature and were integrated in the prototype of the mobile application. Older people's acceptance of the application was assessed by demonstrating the prototype to and interviewing 100 older people living in Beijing. The results highlight the critical impact of perceived benefits or relevancy on older people's adoption of new technology. Implications for the mobile social application for older Chinese people are discussed.

Lessons learned in deploying independent living technologies to older adults’ homes

Independent living technologies are fast gaining interest within both academia and industry, amid the realization that the world’s population is ageing. Technology can increase the quality of life of older people, allowing them to age-in-place and helping them to remain physically, cognitively and socially engaged with their environment. However, little research in this area is applied. The paper argues for the necessity of moving such technology out of the research laboratory and into the home, where its real impact on the lives of older adults can be assessed. Moreover, a series of recommendations are outlined, encompassing the life cycle of independent living technologies, from ethnographic assessment, through to design, deployment and evaluation. This work is based on lessons learned in deploying such technologies to older people in over 200 homes. This paper can act as a guide for other researchers interested in developing technologies with older people.

Developing a pragmatic evaluation of ICTs for older adults with cognitive impairment at scale: the IN LIFE experience

Implementing information and communications technology (ICT) at scale requires evaluation processes to capture the impact on users as well as the infrastructure into which it is being introduced. For older adults living with cognitive impairment, this requires evaluation that can accommodate different levels of cognitive impairment, alongside input from family and formal caregivers, plus stakeholder organisations. The European Horizon 2020 project INdependent LIving support Functions for the Elderly (IN LIFE) set out to integrate 17 technologies into a single digital platform for older people living with cognitive impairment plus their families, care providers and stakeholders. The IN LIFE evaluation took place across six national pilot sites to examine a number of variables including impact on the users, user acceptance of the individual services and the overall platform, plus the economic case for the IN LIFE platform. The results confirmed the interest and need among older adults, family caregivers, formal caregivers and stakeholders, for information and communications technology (ICT). Relative to the baseline, quality of life improved and cognition stabilised; however, there was an overall reluctance to pay for the platform. The findings provide insights into existing barriers and challenges for adoption of ICT for older people living with cognitive impairment.

The computerization,of Burina

Abstract

The information industry is becoming a major source of wealth for many nations; the software industry, in particular, can play an important role in the economies of the developing nations. The Arab countries have a large number of university graduates in computer‐related disciplines; however, the status of the information industry in these countries is far below expectations. One obstacle to the proliferation of computer technology in the Arab societies has been the language barrier. Efforts to Arabize the technology, be it Arabization of software, hardware, user manuals or textbooks and references, are very weak and cannot cope with the rate of advancement in the technology. Furthermore, most Arab countries do not have clear computerization policies, and this has often resulted in the following: nonexistence of serious computer literacy programs, low utilization of information technology in the society, unawareness of the economic and strategic importance of the technology, weak support from higher authorities, weak R &; D efforts and hesitation of the private capital to venture into the information technology sector.

Successful product or successful system? User satisfaction measurement of ERP software

Most software projects are largely undertaken with a focus on developing successful products rather than successful systems. For example, enterprise resource planning (ERP) products are generally developed in isolation from other system components like people, information or existing business processes. This paper applies the human-centred approach in studying the design of SAP-ERP system and measuring its user satisfaction. The objective of the paper is to explore the relationship between the human-centred dimensions (process, syntactic, semantic, social and pragmatic) and the user satisfaction on SAP-ERP system. This paper attempts to answer two questions: what human-centred model can provide a systematic and successful ERP system? And what methodology can be used for validating this model and how can it be applied for evaluating user satisfaction? The contributions of the paper are to address the need for the human-centred approach as a basis for the design of ERP system, to define a systematic human-centred model for measurement towards user satisfaction. This paper suggests the application of a proposed five dimensional model in measuring the human-centredness of SAP-ERP system and embarks a case study to conduct quantitative analysis. In conclusion the paper suggests an urgent and immediate need to develop scientific and engineering methodologies for designing, building, and analysing complex systems that centre on fundamental forms of human activity, supported by computer and communication technology.     

Forum Theatre as a requirements gathering methodology in the design of a home telecommunication system for older adults

The ability to elicit requirements in the design of new technology has proved to be particularly problematic with older generations of users who have not grown up with the same level of familiarity and understanding of present day user interfaces as younger generations have. It is also widely acknowledged that older people are poorly represented in the development process of mainstream technology. In this paper, we critically examine how 'Forum Theatre' can be used as a requirements gathering methodology in the development of a novel digital television (DTV) based communication system. We demonstrate how live theatre established a 'common ground' between audience participants and actors in the facilitation of new ideas, and discuss how live theatre can be used to stimulate interest and understanding from designers and relevant professionals in the development of an unfamiliar and largely undefined technology for older adults.
