Users’ Mental Model Pattern for User Interface Design of Mobile Shopping Apps

In recent years the emergence of smartphones has changed the definition of mobile phones. It has become an essential part of the peoples’ communication and daily life. Mobile apps have become more popular nowadays with the emergence of smartphones. Mobile app is application software designed to run on perspicacious phones and tablet computers. Shopping apps are now the fastest growing apps among mobile apps. Mobile user interface design (UID) is an essential in the mobile apps development process. A poor user interaction in mobile apps could lead to failure of an app. The used of mental model theory could help the mobile apps developers to design a greater user interface (UI). This study discussed on how mental model theory implemented in interface design practices for a mobile shopping app development. Mental model theory using ‘Localization’ and content analysis method will be used throughout this research study. The expected output of this research is to develop a fast, user-friendly and strong visual hierarchy interface guideline for a UID of mobile shopping apps. According to this study, different gender had a different mental model on the user interface for a mobile shopping app

Discovering Autism Child Potential using Autism Parenting Application

Autism have become prevalent disorder among children nowadays. Parents with autism kid having higher level of stress among other parents. There is some remarkable skill in autism kid that by discovering the skill can make parents to have a better approach or better parenting toward their kid. The objective of the study is to identify the remarkable skills among autism children using qualitative method and to identify the features of suitable mobile app to help parent determine the remarkable skills using content analysis and literature review. Two main remarkable skill focusses in this study were rote memory and spatial visual. A study was carried out to produce a mobile application (prototype) for autism parents to discover their child’s remarkable skills. Prototyping methodology was employed. The application is expected to help parents to discover their kid’s remarkable skill. Index Terms - Autism, parenting application, remarkable skill, rote memory, spatial visual

Stress Monitoring Using Mobile Phone and Wearable Technology: Stress Catcher

Individuals nowadays suffered from stress due to high workload from works or studies. However, most of them could not identify their stress level or some of them did not even know that they were exposed to consideration amount of stress. A study was carried out in order to study the mobile application and wearable technology towards the development of stress monitoring application, namely as ‘Stress Catcher’. Through the study, stress-monitoring application was developed based on users’ heart beat rate and users’ perception was evaluated to see how people reacted towards the application. In order to develop the stress monitoring application, Mobile-D methodology was applied. After the study, the stress monitoring application was expected to measure users’ heart beat rate and compared to the heart rate from the signal of pulse that sent to the wearable device, which was Mio Alpha. Mobile application will display the stress level through the display screen. It was hope that Stress Catcher will give early alarm to the users in the early phase to prevent severe stress

Naturally acquired antibody response to Plasmodium falciparum and Plasmodium vivax among indigenous Orang Asli communities in Peninsular Malaysia

Malaria remains a public health problem in many parts of the world. In Malaysia, the significant progress towards the national elimination programme and effective disease notification on malaria has resulted in zero indigenous human malaria cases since 2018. However, the country still needs to determine the extent of malaria exposure and transmission patterns, particularly in high-risk populations. In this study, a serological method was used to measure transmission levels of Plasmodium falciparum and Plasmodium vivax among indigenous Orang Asli communities in Kelantan, Peninsular Malaysia. A community-based cross-sectional survey was conducted in three Orang Asli communities (i.e., Pos Bihai, Pos Gob, and Pos Kuala Betis) in Kelantan from June to July 2019. Antibody responses to malaria were assessed by enzyme-linked immunosorbent assay (ELISA) using two P. falciparum (PfAMA-1 and PfMSP-119) and two P. vivax (PvAMA-1 and PvMSP-119) antigens. Age-adjusted antibody responses were analysed using a reversible catalytic model to calculate seroconversion rates (SCRs). Multiple logistic regression was used to investigate factors associated with malaria exposure. The overall malaria seroprevalence was 38.8% for PfAMA-1, 36.4% for PfMSP-119, 2.2% for PvAMA-1, and 9.3% for PvMSP-119. Between study areas, the proportion of seropositivity for any P. falciparum and P. vivax antigens was significantly highest in Pos Kuala Betis with 34.7% (p < 0.001) and 13.6% (p < 0.001), respectively. For all parasite antigens except for PvAMA-1, the proportion of seropositive individuals significantly increased with age (all p < 0.001). Based on the SCR, there was a higher level of P. falciparum transmission than P. vivax in the study area. Multivariate regression analyses showed that living in Pos Kuala Betis was associated with both P. falciparum (adjusted odds ratio [aOR] 5.6, p < 0.001) and P. vivax (aOR 2.1, p < 0.001) seropositivities. Significant associations were also found between age and seropositivity to P. falciparum and P. vivax antigens. Analysis of community-based serological data helps describe the level of transmission, heterogeneity, and factors associated with malaria exposure among indigenous communities in Peninsular Malaysia. This approach could be an important adjunct tool for malaria monitoring and surveillance in low malaria transmission settings in the country

Evidence of Submicroscopic Plasmodium knowlesi Mono-Infection in Remote Indigenous Communities in Kelantan, Peninsular Malaysia

Malaysia has maintained zero cases of indigenous human malaria since 2018. However, zoonotic malaria is still prevalent in underdeveloped areas and hard-to-reach populations. This study aimed to determine the prevalence of malaria among remote indigenous communities in Peninsular Malaysia. A cross-sectional survey was conducted in six settlements in Kelantan state, from June to October 2019. Blood samples were tested for malaria using microscopy and nested polymerase chain reaction (nPCR) targeting the Plasmodium cytochrome c oxidase subunit III (cox3) gene. Of the 1,954 individuals who appeared healthy, no malaria parasites were found using microscopy. However, nPCR revealed seven cases of Plasmodium knowlesi mono-infection (0.4%), and six out of seven infections were in the group of 19 to 40 years old (P = 0.026). No human malaria species were detected by nPCR. Analysis of the DNA sequences also showed high similarity that reflects common ancestry to other P. knowlesi isolates. These findings indicate low submicroscopic P. knowlesi infections among indigenous communities in Malaysia, requiring PCR-based surveillance to support malaria control activities in the country

A quantitative and qualitative study of user experience impact on mobile game: Preliminary study

This paper presents the effect of great user experience on mobile games. Human-Computer Interaction (HCI) is about the interaction between computer interfaces and humans. In the world of HCI, user experience is one of the common key terms known by all HCI researchers. In HCI, user experience plays an important part to evaluate the user experience design since it is one of the HCI branches that focus interaction of products. The definition of user experience is a degree of positive or a negative emotion that is specific for the user who is experienced in a specific context during and after product use and that motivates for further usage. The goals of this research are to identify the user expectation or experience while playing mobile games and also to examine the triggering context and its regularities with core experience. The method used is mixed methods (qualitative and quantitative) using five participants; consists of an expert mobile gamer, three intermediate mobile gamers and a beginner mobile gamer. Results show that design and development should consider the user’s expectation, to allow the game to achieve its purpose and can influence the users’ mood to play mobile game
