Various challenges of technology use such as the use of technology will affect digital communications. The main purpose of this study is to understand the acceptance of technology and the issues faced by rural communities that include seniors in today's technology. The questionnaires were used to obtain information on the acceptance and problems of rural community technology including the elderly of Mukim Beranang. The number of rural residents is 100 and 45 of them are categorized as seniors aged 55 years and over. The study found that the level of technology utilization was still low among the elderly even though 64.4% among them had smartphones and mobile phones. The results of this study show that the main cause of preventing the use of technology among senior citizens is visual impairment, problems in understanding technology and movement problems (trachea, pain in joints). This pilot study has opened a further research on to see what steps and opportunities to enhance and expand the development technology among elderly in the future.

Without proper guidance, the use of visual analytics in complex domain can become an obstacle that hides the usefulness of analytical data. Since evaluation is the only way to identify the effectiveness of visual analytics to represent analytical outcomes, misconception of the evaluation process will bury the relevancy of visualization to support valuable decision. Recently, the nature domain of data has changed and we are now dealing with data that is massive, ambiguous, and dynamic, is often processed in real time. Hence, the data is more complex and cognitive activities that visual analytics facilitates are also getting more complex. Thus, this research revisits the way to evaluate visual analytics in complex cognitive conditions that are natural, uncertain and context dependent. Governed by the Design Science Research Methodology (DSRM), there are three phases involve during the evaluation process; i). demonstrati...

Melody training technology allows users to practise repetitively while also providing feedback on their performance. This paper describes an application that captures the pattern of tarannum melodies (from Quranic recitations) and provides feedback to the user. Recordings of Quranic verses are collected from an expert reciting Bayati tarannum. The samples are pre-processed into segmented tarannum verse-contours using pitch sequences. Using the k-Nearest Neighbor (kNN) classifier, the melody patterns are trained on 20 samples. Input vectors are formed by computing the melody verse-contour representation using mean, standard deviation, and slope values and combining them with an identified Tilt-based contour label. A tarannum training prototype is built to test similarity between a user’s recitation and the trained patterns. To identify similarity between a pai...

The spread of misinformation, especially those related to the COVID-19, can divide and create negative effects of falsehood in society. Individuals can also cause feelings of fear, health anxiety, and confusion in the treatment COVID-19. Although much research has focused on understanding human judgment from a psychological underline, few have addressed the essential issue in the screening phase of what technology can interfere amidst users' attention in sharing information. This research aims to intervene in the user's attention with a visual selective attention approach. This study uses a quantitative method through studies 1 and 2 with pre-and post-intervention experiments. In study 1, we intervened in user decisions and attention by stimulating ten information and misinformation using the Visual Selective Attention System (VSAS) tool. In Study 2, we identified associations of user tendencies in evaluating information using the Implicit Association Test (IAT). The significant results showed that the user's attention and decision behavior improved after using the VSAS. The IAT results show a change in the association of user exposure, where after the intervention using VSAS, users tend not to share misinformation about COVID-19. The results are expected to be the basis for developing social media applications to combat the negative impact of the infodemic COVID-19 misinformation.

To fully comprehend user interaction when sharing information online, we need to examine why users decide to share misinformation without attentive behavior and how the latest attention-based design approach can address this. We investigate and represent knowledge based on Human-Computer Interaction by applying an ontological approach through a thematic literature review to describe a clearly coherent and well-defined pattern about the relationship between attention-based design and user decisions on information sharing. We conducted a review to collect, examine, and synthesize outputs of previous studies, mixing both forward and backward search strategies. Three key themes we identified include attention-based design, attentive behavior for information sharing, and attention-based design on information sharing. The review interpreted that, (1) attention-based design is significantly related to user decisions on information sharing, and a better understanding of the link between these is not yet properly described, (2) attention-based design has a further influence on increasing task effectiveness when users are dealing with a task where they are more focused and aware, (3) attention-based design, including selective attention, can influence user decisions, especially in completing tasks that emphasize a visualbased approach, (4) attention-based design is an indispensable feature to increase user attention when sharing information on the omnipresence of social media, and (5) psychological factors such as social influences, epistemic belief and cognitive dissonance affect user decisions when sharing information.

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.

We used heart rate devices to measure the user experience during a simulation game play called The Sims™ 3. This study does not emphasize the measurement of data, but focuses mainly on experiences in applying a psycho physiological method to capture user experience while playing games. We measured selected participants' heart rates using a heart rate detector while playing a game. The majority of participants had an average of 60-90 bmp heart rates (HR). Our analysis revealed that there was no difference in HR between novice and non-novice players, but that HR had mostly similar patterns amongst the players throughout the game-playing experiment. HR was higher during the interesting or fun activities or tasks. We end by discussing lessons learnt and issues identified in the experiment which are useful for future enhancement.

There are a number of issues mainly on misinterpretations of gestures that are often reported in NUI research. Among the user group is children. A study was conducted to explore the needs among children in understanding NUI interaction. This paper presents a NUI prototype in learning prayers among children. Event Driven Gesture Sequence Mechanism (EDGSM) was implemented in the prototype to address misinterpretations of gestures. This study aims to evaluate the ability of NUI prototype in learning and experience of children in learning prayers. The analysis found that the assessment of learning of NUI able to improve the learning performance and a better experience compared to traditional learning via video. However, the NUI prototype, which is not equipped with EDGSM mechanism, showed no significant increase in learning performance. The prototype equipped with EDGSM showed a significant result and managed to reduce misinterpretation of gestures by 43.27% compared to the prototype using standard mechanisms. This study indirectly encourages NUI designers and developers to focus on the problem of gestures misinterpretation and concern on the needs and capabilities of users, especially children.

Therefore, to allow for a change, persuasive technology must be able to affect users' emotion and make the user trust the technology so that they will adopt the persuasive technology into their daily life routine, as well as continue to use the technology for long period. This paper is aimed to study the relation between users' emotion with trust and persuasion and how they may contribute to the success of changing a person attitude or behavior towards a certain context or issue. Twenty five participants have completed the study in 6 weeks by using two types of persuasive technology that were assessed at three different interaction stages: pre, during and post. Result shows that emotions have a significant effect on trust, whereas the effect of emotions on persuasion using the persuasive technology was mediated by trust.

Since CCA occur in decision making, problem solving and sense making more in the collaborative settings, it becomes essential for business to response and act according to emerging information items to stay relevant in the market. However, the emergence of information which has been known as an ‘uncontrollable entities’ are hard to be determined from information system perspectives. Thus, the management team is having difficulties in utilizing the emergence information to become valuable outcomes for both organization and stakeholders. This paper aims to show how visualization can play an important role to facilitate this challenge. First, we present the emergence challenges from the perspective of relative isolation between the information, mental and representation spaces. Then, we highlight the importance of dynamic concept as a fundamental app...

Literature review highlights the role of human behaviors in personal photographs lifecycle such as capturing, keeping, managing and re-finding personal photographs exaggeratedly without any progress to handle all factors and so forth. Moreover, personal photographs management systems are becoming widespread, which can help people to rapidly re-find their photographs that have been seen before. Yet some research gaps remain in these systems. This study aims to clarify most possible factors, which could influence re-finding personal photographs as with strengths and weaknesses points in existing photographs management systems. It also provides propose directions for future research in this domain. A review of existing studies highlights some gaps in the literature on the role of personal photographs lifecycle, which is followed by questions for future research. Given the richness of personal photographs re-finding domain, the authors believe that the proposed questions offer avenues for scholars to explore and develop greater understanding of the role of personal photographs lifecycle in difficulty of re-finding personal photographs. The authors acknowledge that there are certain limitations to this study, namely, focusing on the review of personal photographs and not on other forms of personal information. The review presents the role of personal photographs lifecycle and its use in the context of re-finding personal photographs. Finally, this study proposes only future research directions that are far from being exhaustive, rather than presenting experimental study results. Reviewing the current literature uncovers a number of gaps regarding the difficulty of re-finding personal photographs.

The capability to interact effectively on health information application among elderly is becoming essential. Mobile technology can monitor diet and lifestyle of the elderly. We developed Nutrihealth application that comprises information on Body Mass Index (BMI), suggested menus, and calories intake. Persuasive techniques were implemented in the design of Nutrihealth mobile apps, to increase user engagement and behaviour change in healthy diet. The work starts with an initial study to select suitable persuasive techniques for elderly. The aim of this work is to evaluate the mobile application that implements a persuasive design. A technology acceptance model named Unified Theory of Acceptance and Use of Technology (UTAUT) has been used in the evaluation phase. Nine (9) elderly participants take part in the in-depth usage study in which they were asked to use the mobile apps for 3-days. The findings show majority of participants (90%) gave positive opinion on the design of the persuasive mobile apps. There is also an improvement in their calories intake during the 3-days study.

A Persuasive System Design (PSD) model offers guidelines for designing and evaluating systems aimed at reinforcing, changing or shaping underlying human behaviour and attitudes. The objective of this study was to investigate the perceptions of older workers towards persuasive principles of PSD that was integrated into an application specifically designed to encourage physical activity. Ten older workers aged 50 to 64 years with different physical activity levels participated in this study. Using a think-aloud technique, the participants interacted with a physical activity application whilst verbally expressing their perceptions towards the persuasive elements. The results indicated that the older worker participants had positive views towards persuasive design principles that fell under the categories of primary task, dialogue support and credibility support. However, the persuasive principle of the social support category received contradictory views. Further, it was discovered that the personalization of persuasive principles, the credibility of tailored contents and the establishment of a sense of similarity are imperative in the designing of effective persuasive physical activity applications targeting older workers.

Thus, it is important to know how successful such web-based interventions are in enhancing older adults' physical activity levels despite these shortcomings. The objective of this study is to review published literature regarding interactive web-based interventions promoting physical activity among older adults. EBSCOhost, ISI Web of Science and ScienceDirect databases were searched to identify relevant peerreviewed papers. Results were summarized in a qualitative way. We included 15 papers reporting on web-based interventions with physical activity components. Ten and two studies respectively indicated positive and negative outcomes, while the outcomes of the remaining three studies are unclear. Despite the fact that computer illiteracy and age-related impairments can both be experienced, there is preliminary evidence that suggests that web-based interventions are effective in encouraging physical activity among older adults.
