This paper discusses the design and development efforts made to collect data using an opportunistic crowdsensing mobile application. Relevant issues are underlined, and solutions proposed within the CHIST-ERA Macaco project for the specifics of collecting fine-grained content and context data are highlighted. Global statistics on the data gathered for over a year of collection show its quality: Macaco...
System response time can greatly affect the user experience. Society has entered the mobile Internet era, and in mobile applications, as carriers of the mobile Internet, response time is an important performance index related to users' attention. Previous studies of user experience of response time have focused more on computers and websites and less on mobile applications. The current study develops...
Inflammatory Bowel Disease (IBD) is an incurable chronic illness needing ongoing outpatient treatment and support. This paper identifies a number of challenges faced by the various stakeholders of the illness, much of which is rooted in a need for more information on how lifestyle, in a broad sense, impacts the disease and explores the potential to utilise smartphones to address some of the identified...
Performance is nowadays becoming a crucial issue for mobile apps, as they are often implementing computational-intensive features, are being used for mission-critical tasks, and, last but not least, a pleasant user experience often is a key factor to determine the success of an app. This paper reports a study aimed at preliminarily investigating to what extent developers take care of performance issues...
Approaches to making cloud operation more efficient, for example through scheduling and power management, largely assume that the workload offered from mobile, user-facing applications is a given and that the cloud must simply adapt to it. We flip this assumption 180 degrees and ask to what extent can we instead shape the user-centric workload into a form that would benefit such approaches. Using...
Smart mobile devices are variously used in the health sector. Some mobile applications empower patients to better understand their health problems, others guide them in health behavior. Moreover, smart mobile devices can be used in clinical research. Mobile crowd sensing has proven high usefulness for collecting health data with high ecological validity in this context. As the core idea, individually...
Being a convenient replacement for their desktop counterparts, social Web applications are nowadays widely employed in diverse aspects of human endeavour, including education. Current body of knowledge on assessment of social Web applications is composed of studies that were mainly focused on quantitative measurement of their quality when they were used in their primary setting. On the other hand,...
Context based Mobile Information Catalog Surveillance is a mobile phone based communication application. This application will give the notification to the user whenever they want to communicate with their mobile virtually. This application proved to get the recent call logs details when you send a command as message to the Android mobile device. It is used on Business point of view surveillance and...
Beacons are small Bluetooth low energy (BLE) signal emitting devices that can transmit data about their location, temperature, motion etc. Various startups have commercialized Beacon based applications, such as for tracking valuable items, micro-location targeting of people, micro payments etc. However, these applications are not customizable beyond the use cases they were designed to serve. We feel...
Mobile data offloading through WiFi is an essential requirement to reduce cellular network traffic. While extensive attempts have been made at mobile data offloading, previous studies have rarely addressed practical issues, such as dealing with diverse user contexts. In this paper, we propose a personalized data offloading scheme to provide maximum throughput within the cellular budget in daily life...
The current study aims to distinguish between two perspectives dominating the mobile phone addiction literature, addiction to a mobile phone and addiction through a mobile phone (i.e. addiction to mobile phone application). We extend state-of-the-art addiction literature by building on dual-systems theory and investigating both perspectives in the same theoretical model. We empirically test our model...
The use of mobile devices for learning is prominent nowadays. Mobile learning has become an essential part to enhance today's learning style. However, technologies still lack abilities to fully understand human reaction and comprehend their cognitive processes to be able to interact with them and deliver the right amount of contents. Therefore, one research scope is having devices which can sense...
Despite the advancements made towards learning such as technological innovations in the classroom and access to learning in general, there are significant challenges that remain especially the modes of delivery of quality education apart from the traditional classroom teaching and learning. In the endeavour to discover feasible solutions for these challenges, much trust has been put in new data and...
Issues related to a properly collection, management and analysis of data are the very first ones to be solved while working with any data source. Especially, it's true for the data sources, which have a property to grow very rapidly and without any clear structure underneath, and such behavior is very typical for the data generated by mobile devices. Thus, current work suggest an principle architecture...
Developing commercial multimodal interfaces to date has been accommodation of the practical aspect of usability of the application. The advent of advanced mobile devices in combination with new interaction modalities and methods, opens new possibilities in user interface adaptation. In this paper we propose a framework to enhance the user interaction of a social network mobile application with multimodal...
In this paper, we study the value of software project and product measures in the context of Android mobile apps. In particular, we focus on the effort to develop mobile apps and the number of graphical components in these apps. Estimation models are based on information from requirements specification documents (e.g., Number of actors, number of use cases, and number of classes). We have used a dataset...
As mobile applications (apps) become more and more complex, many apps contain various energy bugs, which may cause energy wastes that might reduce the battery life to as short as several hours. Among them, sensor-related bugs such as sensor data underutilization is one of the most common energy bugs. Instead of trying to detect these energy bugs, this paper proposes a method to fix sensor data underutilization...
People can now receive custom-made information through smartphones, tablets or wearable devices. However, people often tend to miss vital information, even reminders, in the flood of notifications. The problem of finding convenient moments for need-to-know information should be investigated. Because each person's message awareness pattern on a smart medium might be different, the necessity of personalized...
The interfacing technologies have motivated the behavior of people and change their living style. Mobile is the prompt entity for human life and the applicant user can't live without it. It means mobile is a necessary entity for human life in similar to cloth, food, water and air etc. The continuous up- gradation into mobile technologies has made them more effective. Currently most of the user uses...
Crowdsensing has been used quite regularly in recent years to study smartphone usage. However context information associated with smartphone usage is mostly of the type geo-localisation, user mobility, temporal behavior etc. Furthermore most studies are not sufficiently user-centric i.e. don't consider the perception or cognitive aspects of the user. In this paper we collect data about social context...
