Advanced Audio Content Management Techniques (Jukka Rauhala) Paper & Slides

Content Browsing in Digital Media Players (Jari Kleimola) Paper & Slides

Contemporary personal content libraries can hold tens or even hundreds of thousands of media items. It is increasingly difficult to locate individual items from a collection of this magnitude, resulting a great demand for usable and attractive content browsing user interfaces. This paper evaluates 14 consumer oriented media player appliances and applications in order to find common patterns behind their conceptual models, views and UI widgets. The evaluation method is informal, using hands-on testing, user manuals and video review material. Unifying conceptual model is then extended with external content aggregation. It was found that the players have generally identical models, views and widgets, but the look and feel layer allows product differentiation. It might also be beneficial to support non-deterministic and content analysis based methods to augment the basic hierarchical and metadata based browsing model.

UI Adaptation (Alessandro Cogliati) Paper & Slides

Personal content can be used on different kinds of computers and consumer electronics devices, such as MP3 players, mobile phones, and digital television set-top boxes. The devices have different kinds of displays and input systems.

Here are some links to most important digital libraries:
The draft version of the paper should contain all the material intended for the presentation. The paper should be improved according to the feedback of the teacher.

The students have to send the presentation slides to the teacher before the workshop. After that the teacher will give feedback on the slides. In additions, student opponents will be assigned for each presentation.

The slides will be presented in full-day workshop. The presentations should last 25 minutes plus 5 minutes for discussion.

After the workshop, the students have to send the final version of the paper to the teacher.

Workshop

The papers will be presented at the end of the course in a full-day workshop. Each paper will be assigned an opponent, who will will comments about the presentation in addition to the course personnel.
