This paper aims to discuss the usability evaluation model for mobile applications used by low vision users. Low vision users have difficulties using mobile applications due to limited view, bright sunshine, small text, and other reasons. This type of user uses mobile applications designed for users with normal vision, and they have many difficulties in reading, accessing, and understanding. Therefore, this paper provides a mobile application usability evaluation model for this type of user, and the proposed model includes usability measures that fulfill their usability requirements. This study employed a systematic review of previous research on good practices and requirements for low vision users to use mobile applications. Also, the new model was evaluated by the domain experts through a focus group session. This model aims to support the development of a mobile application that low vision users can use, which has not been supported in previous studies since it guides mobile application developers to develop mobile applications that fulfill low vision users' usability requirements. It also helps to identify usability problems in the current mobile applications for this type of user. This study will benefit low vision people in using mobile applications effectively, easily, and comfortably.

The usability of the mobile applications is the most important factor in developing, so the key to develop successful mobile applications is usability, especially for users have specific needs such as visually impaired. However, developers do not focus on visually impaired users. Moreover, there are limited studies and usability evaluation models for mobile applications for visually impaired so developers use just a modified usability evaluation methods which are not enough and useful to evaluate mobile applications for visually impaired, or they use general usability evaluation models. Therefore, using these methods or models is difficult for evaluator and not useful for visually impaired users. This study conducts Systematic Literature Review (SLR) to identify usability dimensions that help mobile applications developers and evaluators to evaluate mobile application for users which have moderate and severe visual impairment. The result shows that, six dimensions that have a significant impact on moderate and severe visually impaired users' satisfaction, who use mobile applications. These dimensions namely efficiency, effectiveness, satisfaction, errors, accessibility and understandability.

Face To Face Learning

Due to COVID-19, non-F2F (non-face-to-face) learning is being conducted in educational sites around the world. Unlike theoretical subjects, which have a variety of applicable non-F2F learning content, in practical subjects, learners may undergo many difficulties due to many learning activities. Therefore, this research tries to design and develop a mobile application that allows learners to perform a self-diagnostic on their learning progress. In this research, we conducted a mobile application usability evaluation for 36 students who participated in non-F2F Arduino practice learning. To this end, we applied the ADDIE (Analysis, Design, Development, Implement, and Evaluation) model to develop a self-diagnostic mobile application for students’ learning progress according to the learning content. The research tool modified and distributed the question item appropriate for this subject’s study for the mobile usability evaluation that was used in the previous study. This research applied the ADDIE model to analyze the characteristics of students and learning contents, including designed learning contents, database, menu structure, developed learning contents, and mobile application. After using this in non-F2F practice learning for 15 weeks, a mobile application usability evaluation was conducted. As a result of the study, due to receiving usability scores between 3.53 and 4.42, it was found that the learning progress self-diagnostic in non-F2F practice learning was essential and that mobile applications were useful in non-F2F practice learning. Additionally, 33 out of 36 students responded that it would be useful for their learning if they actively used it in other subjects as well. We have found that leveraging self-diagnostic mobile applications through the mobile application usability evaluation tool can be useful for non-F2F practice learning. Additionally, it is expected to be useful for non-F2F practice learning if additional research is conducted on other factors as well such as teaching presence, online learning engagement, and learning flow in the future.

RESUMO. Este artigo apresenta uma abordagem sobre a influência da engenharia semiótica na experiência do usuário de aplicativos mobile. Uma vez que a semiótica se define como o estudo dos signos, dos processos de significação e como os signos e os significados tomam parte na comunicação, os seus estudos estão atualmente voltados para os processos de comunicação mediada por computador entre designers e usuários de sistema, em seus tempos de interação conjunta. Através dos sistemas de interface, por muitos meios diretos e indiretos, designers dizem aos usuários como eles podem ou devem interagir com o sistema, a fim de adquirir um alcance particular de alvos antecipados pelo momento do designing. A mensagem interativa dos designers para os usuários inclui uma “linguagem de interação” que deverá ser utilizada na comunicação de usuários com o sistema. O objetivo deste estudo é ampliar a visão do leitor sobre esta linguagem de interação e a forma como ela é construída no caso de aplicativos móveis. Este estudo contribui com o preenchimento de uma lacuna teórica na compreensão da relação entre semiose e desenvolvimento mobile. Na perspectiva aplicada, a pesquisa oferece contribuições para à comunidade de desenvolvedores de aplicativos móveis quanto à compressão da influência da semiótica na experiência do usuário com a interface do produto desenvolvido. Palavras-chave: Engenharia Semiótica; Experiência do Usuário; Desenvolvimento Mobile.ABSTRACT. This paper presents an approach on the influence of semiotic engineering on the mobile application user experience. Since semiotics is defined as the study of signs, meaning processes, and how signs and meanings take part in communication, their studies are currently focused on the processes of computer-mediated communication between designers and system users, in their times of joint interaction. Through interface systems, by many direct and indirect means, designers tell users how they can or should interact with the system in order to acquire a particular range of anticipated targets by the time of designing. The designers' interactive message for users includes an "interaction language" that should be used in the communication of system users. The purpose of this study is to broaden the reader's view on this interaction language and how it is built in the case of mobile applications. This study contributes to filling a theoretical gap in understanding the relationship between semiosis and mobile development. In the applied perspective, the research offers contributions to the community of mobile application developers regarding the compression of the influence of semiotics on the user experience with the developed product interface. Keywords: Semiotic Engineering; User Experience; Mobile Development.

Usability Evaluation Methods

Usability is a factor that indicates the success of an interactive product or system, such as a mobile application. The increasing use of smartphones demands a more accurate and effective usability evaluation method to find usability problems, so that they can be used for product improvement in the development process. This study compares the Cognitive Walkthrough method with Heuristic Evaluation in evaluating the usability of the SIRS Del eGov Center mobile application. Evaluation with these two methods will be carried out by three evaluators who act as experts. Finding problems and recommending improvements from each method will produce an improvement prototype made in the form of a high-fidelity prototype. Each prototype will be tested against ten participants using the Usability Testing method, which will generate scores through the SUS table. From the test scores, the percentage of Likert scale and the success rate of each prototype will be found. The results show that between the two usability evaluation methods, the Heuristic Evaluation method is the more effective method, finds more usability problems, and has a higher Likert scale percentage, which is 66.5%, while Cognitive Walkthrough is 64.75%.

Mobile phone have user’s personal and private information. When mobile applications have the permission to access to this information they may leak it to third parties without user’s consent for their own benefits. As users are not aware of how their personal information would be used once applications are installed and permissions are granted, this raises a potential privacy concern. Therefore, there is a need for a risk assessment model that can intimate the users about the threats the mobile application poses to the user's private information. We propose an approach that helps in increasing user’s awareness of the privacy risk involved with granting permissions to Android applications. The proposed model focuses on the requested permissions of the application and determines the risk based on the permission set asked and gives a risk score.
