By Ms. Katarzyna Wac

Abstract Increasingly, we use mobile applications and services in our daily life activities, to support our needs for information, communication, leisure, or even health and care needs. However, user acceptance of a mobile application depends on at least two conditions: the application's perceived experience, and the appropriateness of the application to the user's context and needs. However, we have a weak understanding of a mobile user's quality of experience (QoE) and the factors influencing it. In my talk i discuss a 4-week-long 29-Android-phone-user study, where we collected both QoE and the underlying network's quality of service measurements through a combination of user, application, and network data on the user's phones. We aimed to derive and improve the understanding of users' QoE for a set of widely used mobile applications in users' natural environments and different daily contexts. I present data acquired in the study and discuss implications for mobile applications design, especially those in mobile health domain. I propose a framework for assuring the user's experience for these applications.

Bio: Ms. Katarzyna Wac is a senior scientist (fr. "MER") at the Institute of Services Science (ISS) of University of Geneva (UniGE) and leader of the Quality of Life (QoL) research area since 2010. She holds a BSc and MSc degree in Computer Science from Wroclaw University of Technology (WUT, Poland), an MSc in Telematics from University of Twente (UT, the Netherlands), as well as a PhD in Information Systems from University of Geneva (Switzerland). In 2003-2004, Ms. Wac was a research staff member at University of Twente. In 2005 she joined University of Geneva as a research and teaching assistant, while keeping her affiliation with the University of Twente. In 2007-2010, Ms. Wac was also affiliated with the MobiHealth BV start-up company. In 2009-2010, Ms. Wac was on leave for a one-year Swiss NSF Fellowship at Carnegie Mellon University (CMU, USA), Human-Computer Interaction Institute (HCII). Along the summer 2013, Ms. Wac was supported by Swiss NSF International Visits program to research at Stanford University (Stanford, USA), and particularly at the Stanford Human-Sciences and Technologies Advanced Research Institute (H-STAR). Ms. Wac's research interests include Quality of Service-aware mobile systems and services with special emphasis on support of adaptive multimedia protocols and Quality of Service mechanisms, especially in the mobile healthcare (i.e., mHealth) domain. Ms. Wac strives towards effective and efficient pervasive mobile computing and communication - meeting the end-user Quality of Service requirements and Quality of Experience expectations. Ms. Wac is since 2012 an Associate Expert of the International Telecommunication Union (ITU) European Regional Initiative for mHealth.
