1st International Conference on Design, User Experience, and Usability (DUXU)/14th International Conference on Human-Computer Interaction (HCI), Florida, United States Of America, 9 - 14 July 2011, vol.6769, pp.521-530
This study evaluated the hypothesis that design aspects of the user interface of the applications and the capabilities and constraints of different mobile devices could affect mobile user experience in social network sites (SNS). For this purpose a qualitative mobile usability test, based on a multi-method approach, was carried out with a sample of 25 Turkish university students who were experienced mobile SNS users. The tests were conducted with two different smartphones: Iphone and Blackberry. The participants were observed during the task executions and additional data was collected by the "think aloud" procedure, eye-tracking and video recording of the participants. A short debriefing interview was also made to gain a detailed insight into the user experience. The findings revealed significant mobile usability problems caused specifically by the user interface features of the applications and limitations of each device and enable to propose guidelines to improve user experience in mobile SNS.
