an automatic user activity analysis method for discovering latent requirements Usability Issue detection on mobile applications
Sensors, 2018Co-Authors: Soojin Park, Sungyong ParkAbstract:Starting with the Internet of Things (IoT), new forms of system operation concepts have emerged to provide creative services through collaborations among autonomic devices. Following these paradigmatic changes, the ability of each participating system to automatically diagnose the degree of quality it is providing is inevitable. This paper proposed a method to automatically detect symptoms that hinder certain quality attributes. The method consisted of three steps: (1) extracting information from real usage logs and automatically generating an activity model from the captured information; (2) merging multiple user activity models into a single, representative model; and (3) detecting differences between the representative user activity model, and an expected activity model. The proposed method was implemented in a domain-independent framework, workable on the Android platform. Unlike other related works, we used quantitative evaluation results to show the benefits of applying the proposed method to five Android-based, open-source mobile applications. The evaluation results showed that the average precision rate for the automatic detection of symptoms was 70%, and the success rate for user implementation of usage scenarios demonstrated an improvement of around 21%, when the automatically detected symptoms were resolved.

OTM Workshops - Usability Issues of e-Learning Systems: Case-Study for Moodle Learning Management System
On the Move to Meaningful Internet Systems: OTM 2008 Workshops, 2008Co-Authors: Miroslav Minovic, Velimir Štavljanin, Miloš Milovanović, Dusan StarcevicAbstract:Mobile devices have potential to be integrated into the classroom, because they contain unique characteristics such as: portability, social interactivity, context sensitivity, connectivity and individuality. Adoption of LMS by students is still on the low rate, mostly because of poor Usability of existing eLearning systems. Usability Issue is rising to the higher level on mobile platform, due to device limitations and also because of context of use. Our hypothesis was that it is wrong to take a mobile device as a surrogate for desktop or laptop PC. By accessing LMS on mobile devices using adaptive technologies, like Google proxy, we didn't acquire the satisfactory results. Possible solution to the problem could be development of rich client applications for today mobile devices that would improve Usability. Results gathered in Usability research conducted among students have confirmed that development of eLearning systems needs to have learner in the center of development process.

Dynamic WAP (Wireless Application Protocol) Page Generation: A Proposed Solution for Small Mobile Screen and Usability Issues
International Journal of Computer Applications, 2013Co-Authors: Muhammad Salam, Nasir Rashid, Fakhre Alam, M. Raees KhanAbstract:Mobile commerce (M-Commerce) is a new commerce pattern in which the purchasing and vending of goods and services is completed through mobile apparatus. Or M-commerce is a business concept, which covering any practice of business transaction or information exchange using wireless and mobile technologies. WAP application is used In order to get access to the information and services in the context of mobile commerce. OBJECTIVE: The first objective of our study is to review the literature thoroughly in order to identify the various Issues related to mobile commerce and WAP applications. The second objective of our study is to propose a suitable solution for the identified Issues. METHOD: we have used ordinary literature review as a research methodology for the identification of various Issues concern to mobile commerce and WAP applications. EXPECTED OUTCOME: The study has explored various Issues related to mobile commerce and WAP applications. During the review we have identified various Issues. Some of the Issues are security Issues, business models Issues, heterogeneity Issues, Usability and small screen Issues. Our study mainly concentrates on small screen and Usability Issue. A propose solution for the small screen and Usability is presented. This paper addresses the small screen and Usability Issues of mobile commerce application. The paper proposes a new approach for designing and developing m-Commerce applications keeping in view the various screen size of different mobile devices. This technique is based on customers' mobile screen size. In order to visualize the Idea University of Malakand WAP portal has been shown on various mobile models using WinWap emulator.
