Building distributed heterogeneous smart phone Java applications an evaluation from a development perspective

The advances in mobile phone technology have enabled such devices to be programmed to run general-purpose applications using a special edition of the Java programming language. Java is designed to be a heterogeneous programming language targeting different platforms. Such ability when coupled with the provision of high-speed mobile Internet access would open the door for a new breed of distributed mobile applications. This paper explores the capabilities and limitations of this technology and addresses the considerations that must be taken when designing and developing such distributed applications. Our findings are verified by building a test client-server system where the clients in this system are mobile phones behaving as active processing elements not just mere service requesters

Objective measurements analysis for usability evaluation of mobile applications for deaf people

Usability evaluation is an important element that will enable to identify performance of any system or application.Through identification of these issue, usefulness of a product can be improvised.Many usability models are available to evaluate the system usability.Usability data can be collected in two different method which is objective data and subjective data.This paper present objective data analysis of usability evaluation conducted with deaf people mobile application.The results show that the application evaluated having usability issue in term of performance which needs to be improvised by the developer to produce better functionality application for deaf people

Mobile application testing matrix and challenges

The adoption of smart phones and the usages of mobile applications are increasing rapidly. Consequently, within limited time-range, mobile Internet usages have managed to take over the desktop usages particularly since the first smart phone-touched application released by iPhone in 2007. This paper is proposed to provide solution and answer the most demandable questions related to mobile application automated and manual testing limitations. Moreover, Mobile application testing requires agility and physically testing. Agile testing is to detect bugs through automated tools, whereas the compatibility testing is more to ensure that the apps operates on mobile OS (Operation Systems) as well as on the different real devices. Moreover, we have managed to answer automated or manual questions through two mobile application case studies MES (Mobile Exam System) and MLM (Mobile Lab Mate) by creating test scripts for both case studies and our experiment results have been discussed and evaluated on whether to adopt test on real devices or on emulators? In addition to this, we have introduced new mobile application testing matrix for the testers and some enterprises to obtain knowledge fro

A usability evaluation of mobile application: A review on usability model for the deaf

Usability is an important attribute that need more concentration in determining the production of a successful mobile application.Currently mobile applications for the deaf has increased tremendously with the increase of the usage of mobile phones.However, usability evaluation model that best suits the evaluation for mobile application for the deaf is rather very general. Usability of the mobile application for the deaf is very limited that makes the evaluation more challenging and difficult.This study reviews the current usability models provide guidelines and usability dimensions used by researchers and discuss the trend for future evaluation of mobile applications for deaf.Result shows that usability for mobile application for the deaf are limited. This study helps mobile developers and evaluators in evaluating mobile application for the deaf

Strategy Patterns for Evaluating and Improving Usability

Patterns have had significant impact in many disciplines, particularly in software and web engineering, and we believe that they also provide a basis for selecting evaluation strategies via practical tips and tricks that can be easily adopted for evaluation and change projects. In this paper, we propose a holistic quality evaluation approach for usability and user experience (UX), which relies on quality views and strategy patterns. A quality view relates accordingly an entity super-category (e.g., product, system, system in use) with a quality focus (e.g., internal quality, external quality, quality in use). Usability and user experience are higher-level characteristics that should be linked to quality views appropriately. Also quality views support ‘influences’ and ‘depends on’ relationships between them. With a concrete evaluation or change project goal, our approach selects and instantiates a suitable strategy from a set of strategy patterns. Practical use of our approach is demonstrated through the specification and use of a strategy pattern in the evaluation of the Facebook mobile app.Sociedad Argentina de Informática e Investigación Operativa (SADIO

Methods of usability evaluations of mobile devices

The usability of applications designed and developed for mobile devices integral user experience, particularly for current touch-screen mobile devices. This conceptual paper provides a profile of the ways in which mobile device usability evaluation methods are being adapted to better reflect technological. With an increasing capacity for greater user interactivity through a range of tasks and in a variety of contexts, the importance and impact of mobile device context-of-use components is of particular interest to researchers. This requires a need for a shift in evaluation method paradigms with a particular focus on methods involving the user, as part of the overall development process. Having a better understanding of the context-of-use may contribute to improvements in mobile device usability and the overall user experience

A longitudinal review of Mobile HCI research Methods

This paper revisits a research methods survey from 2003 and contrasts it with a survey from 2010. The motivation is to gain insight about how mobile HCI research has evolved over the last decade in terms of approaches and focus. The paper classifies 144 publications from 2009 published in 10 prominent outlets by their research methods and purpose. Comparing this to the survey for 2000-02 show that mobile HCI research has changed methodologically. From being almost exclusively driven by engineering and applied research, current mobile HCI is primarily empirically driven, involves a high number of field studies, and focus on evaluating and understanding, as well as engineering. It has also become increasingly multi-methodological, combining and diversifying methods from different disciplines. At the same time, new opportunities and challenges have emerged
