Securing the Elderly: A Developmental Approach to Hypermedia-Based Online Information Security for Senior Novice Computer Users

Whilst security threats to the general public continue to evolve, elderly computer users with limited skill and knowledge are left playing catch-up in an ever-widening gap in fundamental cyber-related comprehension. As a definable cohort, the elderly generally lack awareness of current security threats, and remain under-educated in terms of applying appropriate controls and safeguards to their computers and networking devices. This paper identifies that web-based computer security information sources do not adequately provide helpful information to senior citizen end-users in terms of both design and content

How to make privacy policies both GDPR-compliant and usable

It is important for organisations to ensure that their privacy policies are General Data Protection Regulation (GDPR) compliant, and this has to be done by the May 2018 deadline. However, it is also important for these policies to be designed with the needs of the human recipient in mind. We carried out an investigation to find out how best to achieve this.We commenced by synthesising the GDPR requirements into a checklist-type format. We then derived a list of usability design guidelines for privacy notifications from the research literature. We augmented the recommendations with other findings reported in the research literature, in order to confirm the guidelines. We conclude by providing a usable and GDPR-compliant privacy policy template for the benefit of policy writers

Cultural Marker Identification for Web Application Design Targeted for Malaysian Multicultural Users

The rapid growth of technology result in two contradictory phenomenon, the global world becomes smaller while the internet users increase drastically. This diversity of users becomes the main attention toward the study of human computer interaction due to the influential of users’ background toward the usability of web application whereby combination of color strongly determine user’s preference and engagement level.  Hence, determination of color based cultural marker is crucial to the interface design process in order to fulfill the need of diverse users. Most of the empirical study so far has been carried in western contextual. As a result, suggested marker are not applicable in eastern perspective, particularly Malaysia which consist of multicultural society. This article provides content analysis of the website application targeted to multicultural audience to determine the prominent color based cultural markers. More importantly, identifications of the markers could assist the interface designers towards creating web based application that reflected the multicultural audience preferences

Interface design guidelines of nutritional information application for the elderly

The aim of this study is to evaluate the interface design of nutrition information application for elderly people. Obtaining the proper nutritional information is an important aspect for elderly healthcare. Most information on healthcare can be found from the Internet. However, many elderly people face problems when using the Internet due to their inability to adapt to common platforms of interface design. Due to deterioration in physiological functions, elderly users have different requirements from adult users. A high fidelity prototype on nutrition was developed, taking into consideration the evaluation results from the initial need assessment focus group study. A questionnaire survey was conducted involving 30 respondents aged between 60 and 79 years old. The result reveals that most of the respondents gave a positive feedback to the three main features of interface design, which are simplicity (96%), directness (90%) and consistency (100%). Based on this outcome, it can be concluded that the interface design is well accepted by the elderly respondents

SusOrganic - Development of quality standards and optimised processing methods for organic produce - Final report

The SusOrganic project aimed to develop improved drying and cooling/freezing processes for organic products in terms of sustainability and objective product quality criteria. Initially, the consortium focused on a predefined set products to investigate (fish, meat, fruits and vegetables). Contacting participants in the fruit and vegetable sector showed that there is only little perceived need for making changes for the improvement of the processes. At the same time, it became clear that hops and herb producers (drying) face several challenges in terms of product quality and cost of drying processes. Therefore, the range of products was extended to these products. The results of a consumer survey conducted as part the project showed clearly that consumers trust in the organic label, but also tend to mix up the term organic with regional or fair ­trade. Further, the primary production on farm and not the processing is explicitly included in the consumers’ evaluation of sustainability. Appearance of organic products was found to be one of the least important quality criteria or attributes regarding buying decisions. However, there are indications that an imperfect appearance could be a quality attribute for consumers, as the product then is perceived to be processed without artificial additives. Regarding drying operations, small scale producers in the organic sector often work with old and/or modified techniques and technologies, which often leads to an inefficient drying processes due to high energy consumptions and decreased product quality. Inappropriate air volume flow and distribution often cause inefficient removal of the moisture from the product and heterogeneous drying throughout the bulk. Guidelines for improvement of the physical setup of existing driers as well as designs for new drying operations, including novel drying strategies were developed. Besides chilling and freezing, the innovative idea of superchilling was included into the project.The superchilled cold chain is only a few degrees colder than the refrigeration chain but has a significant impact on the preservation characteristic due to shock frosting of the outer layer of the product and the further distribution of very small ice crystals throughout the product during storage. Super­chilling of organically grown salmon eliminated the demand of ice for transport, resulting in both, a reduction of energy costs and a better value chain performance in terms of carbon foot printing. This is mainly due to the significantly reduced transport volume and weight without the presence of ice. The product quality is not different but the shelf life is extended compared to chilled fish. This means that the high quality of organic salmon can be maintained over a longer time period, which can be helpful,e.g. to reach far distant markets. The same trend was found for superchilled organic meat products such as pork and chicken. The consortium also developed innovative noninvasive measurement and control systems and improved drying strategies and systems for fruits, vegetables, herbs, hops and meat. Those systems are based on changes occurring inside the product and therefore require observation strategies of the product during the drying process. Through auditing campaigns as well as pilot scale drying tests it has been possible to develop optimisation strategies for both herb and hops commodities, which can help reduce microbial spoilage and retain higher levels of volatile product components whilst reducing the energy demands. These results can be applied with modifications to the other commodities under investigation. The environmental and cost performance of superchilling of salmon and drying of meat, fruit and vegetables were also investigated and the findings indicated that both superchilling and drying could improve sustainability of organic food value chains especially in case of far distant markets. An additional outcome of the project, beyond the original scope was the development of a noninvasive, visual sensor based detection system for authenticity checks of meat products in terms of fresh and prefrozen meats

Culture Centered Design: Reviews on Cultural Factors Influencing Interface design Elements

Issues regarding misconception of the same piece of information are solicited from users with different cultural background and needs. Various efforts have been conducted to cater to such issue. However studies regarding cultivation of cultural elements in user interface design seem to be neglected. Numerous studies show that interface design preferences are related to the user’s cultural background. Furthermore, studies of user cultural needs could enhance user’s understanding and acceptance of the interface design. Thus, the purpose of this article is to review the cultural factors influencing interface design elements. Indirectly, it exhibits the concept of culture centered design

Implicit and explicit risk perception, affect, and trust : an investigation of food "traffic lights"

Obesity is a health problem in many developed countries and is a growing problem worldwide. In an effort to improve food choices the "traffic lights" nutritional labelling system has been developed. This system informs consumers of the relative (low, medium, high) levels of fat, saturated fats, sugar, and salt, along with energy information. There is debate over what type of thought processing drives perceptions of affect (or emotion) and risk regarding food products. These are System 1 (quick, intuitive) processing and System 2 (slower, deliberative) processing. In order to capture data on both types of processing, we used explicit and implicit measures (we developed an implicit measure of risk for this study). We also investigated the relationships of risk with affect, and trust. The results showed the presence of food "traffic lights" sometimes influenced both risk and affect perceptions but this was more pronounced for explicit measures. We also found that high risk was associated with negative affect, and low risk with positive affect, with larger effects when the “traffic lights” were present. We concluded that "traffic lights" can influence risk perception at both explicit and implicit levels but the influence was stronger if either the risk information was clear or the person was consciously evaluating the risk. Future research was discussed
