CONTEXT ONTOLOGY IN MOBILE APPLICATIONS

<span>Persuasive design principles (PDP) of persuasive system features framework have shown impressive results from the context of user engagement and acceptance as well as continuous usage towards the persuasive systems involved. Yet, available literatures do not thoroughly address the implementation of these design principles specifically in mobile applications and there is insufficient discussion on the impact of the principles in relation to the overall achievement of mobile applications. Hence, this research was conducted with the aim to qualitatively explore the way PDP were implemented across three different levels of mobile applications’ attainment. For this study, seven semi-structured interviews were conducted with the involvement of fifteen (15) Android mobile applications in the area of utilities category. These mobile applications were then categorized into three categories which is successful, partially successful and less successful based on their numbers of mobile applications downloaded for three consecutive years. The results from the content analysis revealed that each of the PDP were implemented in many ways yet the most common applied principles are reduction, tailoring and personalization. However, the analysis also shows low numbers of implementation from the system credibility and social support category. <span>In addition, most of the mobile applications of the successful category have implemented a lot more PDP as compared to the other two mobile application categories. The results from this study has provide significance towards developers, practitioners as well as the scholars from the contextual perspective of persuasive system framework also the practical values of the principles specifically the implementation in mobile application development.</span></span>

At present, the lack of adequate methods to test whether a mobile application is accessible has become a major challenge for accessibility experts. This study was applied to ten mobile applications, the most popular according to PCMAG. We propose to use the Web Content Accessibility Guidelines 2.1 through manual review and automatic review with the Google Play Store Accessibility Scanner validator for the Android. The evaluation results of the mobile applications indicate that the applications are not accessible because they do not comply with the minimum required level proposed by WCAG 2.1. The research proposes suggestions to improve and raise awareness among the designers of mobile applications, in such a way that more inclusive mobile applications accessible to all types of users are built.

Context The source code of a mobile application has several components (i.e., code units) and they have a cost (e.g., test creation and execution) and benefit (e.g., find bug) value for performing unit testing. Problem Choosing in which components unit tests should be done, in order to increase the benefit (effectiveness) and decrease the cost of this activity. Proposal This study presents an approach that supports the selection of components for unit test creation in Android mobile applications. The SCUTMA approach allows the selection of components with respect to the following criteria, which can be combined: Cost of future maintenance, propensity to defects, frequency of call, risk of failure, market vulnerability and business value. Results Two empirical studies were performed to evaluate SCUTMA. The first study aimed at analyzing the correlation between the metrics that represent the criteria described above, where the result showed the possibility of using the metrics Cost of Future Maintenance (CFM), Code Smell (CS), Frequency of Calls (FC), Fault Risk (FR), Market Vulnerability (MV) and Business Value (BV) combined in a solution for component selection. The second study aimed to evaluate the effectiveness of using the SCUTMA approach. The result indicates that SCUTMA selected more components with error (58.33%) than the selection performed by specialists (40%). Conclusions The SCUTMA approach is effective in selecting components for creating unit tests in Android mobile applications.

Fear Filter is a digital artwork comprising of a mobile phone photo filters application for Android / iOS platforms and a digital photo stream. The photo filters are created by gathering current and historical information about the UK Threat Level from a live feed from MI5, the UK security service. Photographs taken with the mobile application are transformed by the photo filters, each of which correspond to a different moment in time and the related Threat Level from that period. The filters cover the period 1 August 2006 until the present moment. Photos shared from the mobile application are automatically posted to a public photo stream. The artwork draws together the ubiquity of photography as a networked medium and the growing use of photo filters apps with the invisible ubiquity of the UK Threat Level. Utilising pattern recognition and algorithmic image analysis each photo filter visualises the UK Threat Level by colourising and redacting the subject of the photograph according to the severity of the Terror Threat Level. Fear Filter exploits the confluence of mobile digital photography, platforms, networks and the online security theatre of the UK Threat Level to reformulate the relationship between photography and terrorism.

Mobile systems and mobile applications have gained a lot of attention both in research and industry over the last years. The market share of mobile devices is constantly growing. More and more, users expect their mobile devices to provide functionality similar to the one they know from their desktop computers, but also to provide additional, mobile device specific functionality, like location based services. However, software development for mobile devices is still cumbersome and a methodology geared towards supporting the development of such mobile applications is still lacking. While there is broad agreement that developing for mobile devices is more difficult than traditional software engineering, we lack a precise understanding that goes beyond anecdotic evidence of why this is the case and how the situation can be ameliorated. We do not precisely know where and how the development of mobile application differs from “normal” software development and where new methodologies are needed. Aspects that need to be addressed in this context are, among others, the questions of software architectures for mobile applications, approaches to the software design for mobile applications and how the consequences of being mobile, e. g., changing location, changing context, changing connectivity, heterogeneous software and platforms influence the software development process and what design approaches do reflect the specialties of mobile applications and systems appropriately. While this special issue cannot provide a definite or complete answer to these questions, it does provide answers to some important aspects. In the following, we will first try to get a more thorough understanding of some of the main differences between mobile and classical application development and will then discuss how the papers contained in this special issue address these differences.

Mobile applications are an essential element in pervasive and ubiquitous computing, and they face many challenges during their generation process from the analysis of user needs to the design of specific mobile interfaces and their development in several technological platforms. Moreover, the rise of Ambient Intelligent and context-aware environments also introduces multiple interaction aspects to be considered when using mobile devices in this kind of scenarios. The present work seeks to examine the role of design patterns and ontology models in order to help with the generation of mobile applications, which can be adapted at runtime to the various user needs, different context scenarios, interactive design modes, or technology requirements. In this way, an ontology-based framework is introduced to represent, design, and support the adaptation of user interfaces in mobile applications by using design patterns according to these user needs or preferences and the context around them. This framework provides developers with a client-server architecture that enables the access to an expert knowledge base of user, context, and pattern information together with a set of inference rules, which allow the dynamic selection of interface design patterns and the runtime adaptation of the user interface features. These ontology models and inference rules are key components of the proposed framework, and their implementation has helped to produce an example of mobile application supporting user interface adaptation processes for disabled people, which can be required in Ambient Intelligent environments. Three examples of user scenarios have been considered to assess the framework potential, and usability dimensions have been tested by a limited set of users through the produced mobile application, making the usefulness of generated adaptive user interfaces apparent.

Wireless Sensor Networks (WSNs) belongs to a new trend in technology in which tiny and resource constrained devices are wirelessly interconnected and are able to interact with the surrounding environment by collecting data such as temperature and humidity. Recently, due to the huge growth in the use of mobile devices with Internet connection, smartphones are becoming the center of future ubiquitous wireless networks. Interconnecting WSNs with smartphones and the Internet is a big challenge and new architectures are required due to the heterogeneity of these devices. Taking into account that people are using smartphones with Internet connection, there is a good opportunity to propose a new architecture for wireless sensors monitoring using push notifications and smartphones. Then, this paper proposes a ubiquitous approach for WSN monitoring based on a REST Web Service, a relational database, and an Android mobile application. Real-time data sensed by WSNs are sent directly to a smartphone or stored in a database and requested by the mobile application using a well-defined RESTful interface. A push notification system was created in order to alert mobile users when a sensor parameter overcomes a given threshold. The proposed architecture and mobile application were evaluated and validated using a laboratory WSN testbed and are ready for use.

The alarming rise in kidnapping incidents across Nigeria demands innovative, reliable, and context-appropriate personal safety solutions. Existing GSM panic buttons and mobile applications are often hindered by hardware constraints, dependence on constant internet connectivity, and slow activation under duress. This paper presents the design and implementation of an anti-kidnapping system that integrates an ESP8266-based emergency button with an Android mobile application, enabling dual-mode alert delivery via Internet or SMS. When the emergency button is pressed, the ESP8266 powers on and instantly enters Wi-Fi Access Point (AP) mode. The Android application, running a foreground service, connects as a client, acquires GPS coordinates from the phone, and combines them with a timestamp and the user’s preconfigured emergency contacts. This information is sent to an IoT server, which triggers notifications via Firebase Cloud Messaging. If internet connectivity is unavailable, the application automatically switches to SMS mode to ensure alert delivery. Hardware-triggered activation and firmware-controlled power-down ensure zero standby power consumption, enabling extended operational readiness on a single charge. Field tests across varying connectivity conditions showed activation in less than 2 seconds, alert delivery in 5–9 s depending on connectivity, and GPS accuracy typically within ±10 m. The system’s low cost, portability, and independence from continuous network access make it suitable for deployment across Nigeria’s urban, rural, and low-resource settings, with potential for broader emergency response applications.

In today's dynamic networking environment, securing access to resources has become increasingly challenging due to the growth and progress of connected devices. This study explores the integration of Role-Based Access Control (RBAC) and OAuth 2.0 protocols to enhance network access management and security enforcement in an Android mobile application. The study adopts a waterfall methodology to implement access control mechanisms that govern authentication and authorization. OAuth 2.0, a widely adopted open-standard authorization framework, was implemented to secure user authentication by allowing third-party access without exposing user credentials. Meanwhile, RBAC was leveraged to streamline access permissions based on predefined user roles, ensuring that access privileges are granted according to hierarchical role structures. The main outcomes of this study show significance towards the improvements in security enforcement and user access management. Specifically, the implementation of multi-factor authentication, session timeout mechanisms, and user role-based authorization ensured robust protection of sensitive data while maintaining system usability. RBAC proved effective in controlling access to various system resources, such as database operations which was presented in scenario of physical access to doors, while OAuth 2.0 provided a secure communication channel for authentication events. These protocols, working in tandem, addressed key issues like unauthorized access, data integrity, and scalability in network security policy enforcement. This research deduces that combining RBAC and OAuth 2.0 protocols in mobile applications enhances security posture, simplifies access management, and mitigates evolving threats.
