TAILIEUCHUNG - Advantages and challenges of tablet PC’s usage
In this study we were interested in evaluating tablet PC device performances, as well as how the respondents perceived its usability. Usability of this kind of device is furthermore investigated in comparison to the other similar mobile devices. The Technique for Order Preferences by Similarity to an Ideal Solution (TOPSIS) is specifically implemented and its outcomes are compared with the calculated System Usability Scale (SUS) scores. | Yugoslav Journal of Operations Research 26 (2016), Number 4, 527-537 DOI: ADVANTAGES AND CHALLENGES OF TABLET PC’S USAGE Svetlana ĈIĈEVIĆ University of Belgrade, Faculty of Transport and Traffic Engineering, Vojvode Stepe 305,11000 Belgrade, Serbia, Slobodan MITROVIĆ University of Belgrade, Faculty of Transport and Traffic Engineering, Vojvode Stepe 305,11000 Belgrade, Serbia, Milkica NEŠIĆ University of Niš, Faculty of Medicine, Bulevar dr Zorana Đinđića 81, 18000 Niš, Serbia, milkica@ Received: April 2014 / Accepted: August 2014 Abstract: In this study we were interested in evaluating tablet PC device performances, as well as how the respondents perceived its usability. Usability of this kind of device is furthermore investigated in comparison to the other similar mobile devices. The Technique for Order Preferences by Similarity to an Ideal Solution (TOPSIS) is specifically implemented and its outcomes are compared with the calculated System Usability Scale (SUS) scores. One of the TOPSIS method advantages is its ability to identify the best alternative quickly and precisely, which is also one of the most important features of SUS scale.

INTRODUCTION In recent years, information management has greatly benefited from advances in Information and Communications Technology (ICT) through increasing the speed of 528 Ĉiĉević, S., Mitrović, S., Nešić, M. / Advantages And Challenges of Tablet PC’ S Usage information flow, enhancing the efficiency and effectiveness of information communication, and reducing the cost of information transfer. There has been a shift from e-learning, to m-learning (mobile learning) and now, more recently, the idea of ubiquitous learning. The applications of mobile learning range widely, from high school to university .
