Leino, Juha, Finnberg, Sanna and Räihä, Kari-Jouko (2010): The times they are a-changin': mobile PIM is leaving the paper trail behind. In: Proceedings of the HCI10 Conference on People and Computers XXIV 2010. pp. 259-268.

Use practices in personal information management (PIM) evolve continually. The data from our two studies, a survey study (n=61) on to-do use practices and a diary/interview study (n=11) on smartphone use in PIM, suggests that electronic PIM has finally reached paper-based PIM in popularity. Mobile phones and their development have been integral to this development: Better input possibilities and better screens together with improved Internet accessibility have made it possible for us to increasingly organize our lives with mobiles. Thus, mobiles have to be in the epicenter when designing the PIM applications of tomorrow.

Leino, Juha and Räihä, Kari-Jouko (2007): Case Amazon: ratings and reviews as part of recommendations. In: Proceedings of the 2007 ACM Conference on Recommender Systems 2007. pp. 137-140.

We studied user behavior in a recommender-rich environment, Amazon online store, to see what role the algorithm-based and user-generated recommendations play in finding items of interest. We used applied ethnography, on-location interviewing and observation, to get an accurate picture of user activity. We were especially interested in the role of customer ratings and reviews and what kind of strategies users had developed for such an environment. Our results underline the need to develop recommender systems as a whole. The way the recommendations are shown affects which items get picked, and for improving the interface, it is necessary to study the whole in addition to studying the parts in isolation.
