New paradigms such as pervasive computing, cloud computing, and the internet of things (IoT) are impacting the business world. Smartphones are at the core of these paradigms by allowing us interaction with the world around us. In light of this, it is imperative to migrate a lot of existing non-mobile software to adapt it to the new technological reality. The main challenge to achieve this goal is the proliferation of mobile platforms. An integration of ADM (Architecture Driven Modernization), cross-platform development and formal metamodeling to face this kind of migration is described. The proposal was validated with the migration of object-oriented software to different mobile platforms through the multiplatform language Haxe. A comparison of the approach with traditional migration processes and the description of existing challenges in real projects of the scientific and industrial field are included.

SummaryBackground: Mobile health (mHealth) is a growing field aimed at developing mobile information and communication technologies for healthcare. Adolescents are known for their ubiquitous use of mobile technologies in everyday life. However, the use of mHealth tools among adolescents is not well described.Objective: We examined the usability of four commonly used mobile devices (an iPhone, an Android with touchscreen keyboard, an Android with built-in keyboard, and an iPad) for accessing healthcare information among a group of urban-dwelling adolescents.Methods: Guided by the FITT (Fit between Individuals, Task, and Technology) framework, a think-aloud protocol was combined with a questionnaire to describe usability on three dimensions: 1) task-technology fit; 2) individual-technology fit; and 3) individual-task fit.Results: For task-technology fit, we compared the efficiency, and effectiveness of each of the devices tested and found that the iPhone was the most usable had the fewest errors and prompts and had the lowest mean overall task time For individual-task fit, we compared efficiency and learnability measures by website tasks and found no statistically significant effect on tasks steps, task time and number of errors. Following our comparison of success rates by website tasks, we compared the difference between two mobile applications which were used for diet tracking and found statistically significant effect on tasks steps, task time and number of errors. For individual-technology fit, interface quality was significantly different across devices indicating that this is an important factor to be considered in developing future mobile devices.Conclusions: All of our users were able to complete all of the tasks, however the time needed to complete the tasks was significantly different by mobile device and mHealth application. Future design of mobile technology and mHealth applications should place particular importance on interface quality.Citation: Sheehan B, Lee Y, Rodriguez M, Tiase V, Schnall R.

This paper presents a star-tracking algorithm to determine the accurate global orientation of autonomous platforms such as nano satellites, U A V s, and micro-drones using commercial-off-the-shelf ( C O T S ) mobile devices such as smartphones. Such star-tracking is especially challenging because it is based on existing cameras which capture a partial view of the sky and should work continuously and autonomously. The novelty of the proposed framework lies both in the computational efficiency and the ability of the star-tracker algorithm to cope with noisy measurements and outliers using affordable C O T S mobile platforms. The presented algorithm was implemented and tested on several popular platforms including: Android mobile devices, commercial-micro drones, and Raspberry Pi. The expected accuracy of the reported orientation is [0.1°,0.5°].

The fast and global way which has characterized the presence of mobile phones in society has sparked the interest of several sectors of activity, including journalism. From the early stages of production to distribution, and then through the characteristics of content and consumption patterns, numerous changes have been introduced by these mobile devices in an activity that has been undergoing one of the most uncertain moments in its long history. This uncertainty has stemmed from the decrease in income which was caused by the emergence of new competitors, such as the online press and social networks. This bibliographic review aims at identifying the changes caused by smartphones in the production distribution and consumption of news, analyzing its effect on the epistemology of journalism. We attempt to ascertain if the increasing influence of mobile technologies in the journalistic activity has changed its nature, improving the production of knowledge. Upon closer reading of the bibliography, it can be concluded that the versatility of mobile devices has facilitated a set of new possibilities not only for journalists, namely more autonomy and a reduction in the time spent between the event and the publication, but also for consumers, who can do a mobile and personalized consumption on their screens. Due to its ability to continuously adapt to the rhythm of contemporary society, mobile journalism has become more universal and has been confirmed as a form of knowledge insofar as it responds more effectively to consumers’ expectations, in particular young people’s, who are moving away from journalism and thus prevent the generational renewal of readers, something which is fundamental for the media business model.

Different Levels

On one hand, healthcare has taken the centre stage of attention in recent years, due to many more activities of both natural and manmade. On another hand, the use of mobile technologies is increasingly growing across the world, particularly in developing countries. Mobile devices, including phones and computers are becoming significant ICT tools for many activities and process of healthcare service delivery in both urban and rural areas, by organisations and individuals, literates and educated. Also, both businesses (organisations) and individuals are involved in the delivering and accessibility (recipient) of healthcare services at different levels and locations. The nature of the diverse tribes and languages within some developing countries make it difficult to deliver or receive the services which are provided by some Healthcare organisations. This is so because particular language, such as English, as in the case of South Africa, is often used for communication. Even though majority of the citizens make use of Mobile devices (such as cellular phones), the media of communication exchange is English language. Due to the sensitivity, confidentiality, and private nature of healthcare information and services, a one-on-one and the use of language which the patient is comfortable with is critical. Otherwise, the services and objectives of the healthcare organisations continue to be challenged. As such, there is need to address the semantics of language through the use of electronic devices for healthcare services.

Search Systems

AbstractWith the development of mobile technologies, voice search is becoming increasingly important in our daily lives. By investigating the general usage of voice search and user perception about voice search systems, this research aims to understand users’ voice search behavior. We are particularly interested in how users perform voice search, their topics of interest, and their preference toward voice search. We elicit users’ opinions by asking them to fill out an online survey. Results indicated that participants liked voice search because it was convenient. However, voice search was used much less frequently than keyboard search. The success rate of voice search was low, and the participants usually gave up voice search or switched to keyboard search. They tended to perform voice search when they were driving or walking. Moreover, the participants mainly used voice search for simple tasks on mobile devices. The main reasons why participants disliked voice search are attributed to the system mistakes and the fact that they were unable to modify the queries.

L2 Vocabulary

Abstract Considerable research has been conducted on the advancement of mobile technologies to facilitate vocabulary learning and acquisition in a second language (L2). However, whether mobile platforms lead to a comprehensive mastery of both receptive and productive vocabulary knowledge has seldom been addressed in previous literature. This study investigated English vocabulary learning from engagement with mobile-based word cards and paper word cards in the context of the Chinese university classroom. A total of 85 undergraduate students were recruited to take part in the study. The students were divided into two groups, a mobile learning group and a paper-based learning group, and tested on two word knowledge components: receptive knowledge of the form–meaning connection and productive knowledge of collocations. Both the digital and non-digital word cards enhanced L2 vocabulary learning, and the results showed that the mobile application (app) promoted greater gains than physical word cards.
