The number of mobile users have grown tremendously in the past few years. Nowadays, mobile phones are not just used for the purpose of making calls, rather they have become an important modern gadget which helps people in various aspects of their lives. With this increase, a lot of time on mobile is spent in browsing the internet websites through mobile web browsers. Hence, mobile web browsers actually...
Advances in mobile technologies have led to the use of mobile devices in telemedicine. Examples include smartphones for capturing microscopic images from glass slides for remote telepathology and in teledermatology consultations. As use of smartphones become even more pervasive in developing countries where expert medical consultation is greatly needed, telemedicine, such as telepathology and telemicroscopy...
With the development of computers, the Internet and mobile technologies, different needs have emerged for people and different solutions have been discovered to meet these needs. One of the critical areas which are considered as the main factor in creating the tomorrow of human beings where a careful study should be done is the education and teaching. Many technologies are being used and various methods...
This paper presents results of a survey that explored the challenges low-income mobile users of Dhaka, Bangladesh (N = 131) face in mobile text entry. Results revealed that all users use the Bengali language at some capacity to compose text, yet many (are forced to) write with the Roman alphabet. Both feature phone and smartphone users feel that the existing text entry techniques are difficult to...
There has been series of introduction of low-cost learning technologies worldwide such as laptop and tablet computers, especially in developing countries to address uneven standard education which has attracted attention from many researchers and practitioners as reflected in myriad studies. The State Government of Osun in Nigeria following the trend of technology globally introduced Opón Ìmò Initiative...
Given mobile devices ubiquity and capabilities, some researchers now consider them as resource providers of distributed environments called mobile Grids for running resource intensive software. Therefore, job scheduling has to deal with device singularities, such as energy constraints, mobility and unstable connectivity. Many existing schedulers consider at least one of these aspects, but their applicability...
Android has become the most widely used mobile operating system (OS) in recent years. There is much research on methods for detecting malicious Android applications. Dynamic analysis methods detect such applications by evaluating their behaviour during execution. However, such mechanisms may be ineffective as malware is often able to disable antimalware software. This paper presents the design of...
Usability is one of the factors that determine the success of a system. To improve it is necessary to evaluate the interfaces using evaluation methods. Often the results of these evaluations are different when performed by different people, indicating lack of sistematicity and predictability of evaluation results. Questionnaires are methods used to collect opinions of the users about the usability...
In the quest to engage and motivate users on the use of mobile applications, the gamification concept has been excelling in the market since incorporates game elements in a non-game context. Scoring systems, challenges, competitions and badges, are some of the elements implemented in many fields, such as health, education, ecological awareness, among others. In this context, this study aimed to systematically...
The electronic collection of patient information is a common practice across healthcare organisations in South Africa. Patients are encouraged to manage and control their own health data and information through the use of personal electronic health records (PEHRs). However, as this is a new type of electronic health record, there are concerns that must be addressed before patients make use of the...
Offloading has emerged as a promising idea to allow resource-constrained mobile devices to access intensive applications, without performance or energy costs, by leveraging external computing resources. This could be particularly useful in enterprise contexts where running line-of-business applications on mobile devices can enhance enterprise operations. However, we must address three practical roadblocks...
The article researches and analyzes the architecture and application fields of mobile computing clouds. Advantages of these technologies and problems occurring during their use are analyzed. At the same time, issues related to provision of demand for computing and memory resources of mobile devices using this technology are studied.
Mobile devices often operate in resource constrained envi- ronments with intermittent connectivity, bandwidth, bat- tery power, etc. On these devices, existing cooperative con- tent sharing protocols and models (e.g. Peer to Peer and client-server) present major drawbacks. Presently, a user has to maintain the connection between the peers when down- loading content. For instance, when a large multimedia...
With the ubiquitous usage of mobile devices, most communications are now impacted by the users' mobility. Therefore, applications and services must be designed to cope with network dynamics produced by those mobility patterns. Software research and development would benefit from taking device mobility into account. However, implementing and testing software on real devices is costly and cumbersome...
This paper introduces the design and implementation of a middleware for mobile devices that can interact each other at a close range. In a case that the users of some application service locate within a short distance, it is inefficient for users to communicate with others via a remote server on the network. Communicating between users directly is much better and faster than being relayed by a remote...
Mobile technology enables the generation and collection of previously unobtainable amounts of data. This data is becoming a powerful tool in the delivery of healthcare. Both internal devices sensors and externally connected sensors are used to collect measures, which are then aggregated, into useable information. Current trends in mobile technology, such as cloud computing and external storage make...
Palmprint ROI (Region of Interest) extraction is an important procedure in palmprint recognition or authentication which mainly aims to obtain standardized images for feature extraction and matching. ∗Locating contactless palmprint ROI in complex environment is a challenging work because of unstable external factors and relaxed operation environment. As to mobile palmprint recognition, the inherent...
In the aftermath of a natural or industrial disaster, locating individuals is crucial. However, disasters can cause extensive damage to the network infrastructures and a generalized loss of communication among survivors. In this article, we present a network support solution that provides a post-disaster geolocation-collecting service that relies on inter mobile device connections. On top of this...
As mobile software development becomes more mainstream, universities recognize a need to integrate mobile platform programming into the curriculum. This integration requires an understanding of mobile software development that defines it not just as a collection of topics but that acknowledges cross-topic areas that serve as the basis for specific interests. This paper presents a platform-agnostic...
One of the biggest challenges teachers are facing is the inability of students to interact with each other. The instructor may ask for students' opinion, their ideas and whether they agree or disagree on a given problem or statement, without getting any feedback. However, some students have communication difficulties, and those who can have the correct answer may feel uncomfortable, and therefore...
