Analysing user experience of personal mobile products through contextual factors

by Kaisa Väänänen-vainio-mattila and Hannu Korhonen

Proceedings of the 9th International Conference on Mobile and Ubiquitous Multimedia - MUM '10, 2010

In UX studies, context is often seen as a single entity such as mobile context or car context. More fine-grained categorization of contextual factors is needed when we want to understand how context affects user experience. The purpose of our study was to adapt existing context and

Exploring Playability of Social Network Games

Due to their design characteristics, new challenges for game design and playability evaluations arise. We present a study where 18 novice inspectors evaluated a social game using playability heuristics. The objective is to explore possible domain-specific playability problems and to examine how the established heuristics suit for evaluating social games. The results from this study show that some implementations of the social games design ...

Common playability problems in social network games

Social network integration and the free-to-play revenue model make them easily accessible but also easy to discard. In such an ecosystem, the quality of the game plays an important part. Improving playability is one method for achieving higher quality game experiences which might in turn lead to better retention and monetization. In this work-in-progress paper, we examine 12 social games and present the ten most common problem categories featuring game usability, gameplay and platform related playability problems.

Mobile multimedia presentation editor

Earlier research has shown that the users enjoy creating digital stories with their mobile devices. However, designing editor interfaces that support creation of rich audio-visual presentations has been a major challenge due to the constrained input and output capabilities of mobile devices. In this paper, we present the design and evaluation of the Mobile Multimedia Presentation Editor, an application that makes it possible to author sophisticated multimedia presentations that integrate several different media types on mobile devices. Based on a user study, we present design principles for multimedia presentation editors on mobile devices. We describe an application design that supports these principles and so demonstrate that editing of sophisticated multimedia presentations is feasible on mobile devices. We report evaluations which indicate that the editor application was easy to use and supported the creativity of the mobile users well.
