Ubicomp ISWC Impressions

Usually, I’m not such a big fan of conference openings, yet Friedemann Mattern provided a great intro giving an overview about the origins of Pervasive and Ubicom mentioning all important people and showing nice vintage pictures from Hans Gellersen, Alois Ferscha, Marc Langheinrich, Albrecht Schmidt, Kristof Van Laerhoven etc.

Deeply impressed by the organization, social and general talk quality, I was a bit sceptical before the merger of Pervasive / Ubicom and collocating ISWC, yet it was completely unfounded.

We got some great feedback for Kazuma’s and Shoya’s demos. They both did a great job introducing their work about:

We got also a lof of interest and feedback to Andreas Bulling’s and my work about recognizing document types using only eye gaze. By the way, below are the talk slides and the abstract of the paper.

Reading is a ubiquitous activity that many people even per- form in transit, such as while on the bus or while walking. Tracking reading enables us to gain more insights about ex- pertise level and potential knowledge of users – towards a reading log tracking and improve knowledge acquisition. As a first step towards this vision, in this work we investigate whether different document types can be automatically de- tected from visual behaviour recorded using a mobile eye tracker. We present an initial recognition approach that com- bines special purpose eye movement features as well as ma- chine learning for document type detection. We evaluate our approach in a user study with eight participants and five Japanese document types and achieve a recognition perfor- mance of 74% using user-independent training.
