Fields of Interest

My main research interest is intelligent mobile systems. Much of our work deals with improving the usability of mobile devices by adapting to the user and his/her current situation. Examples of our work include activity recognition from accelerometer data, identifying meaningful places / significant locations from user's location traces and recommendation techniques for mobile applications.

My secondary research topic is related to reputation systems, i.e., mechanisms that aggregrate feedback from users and provide summaries about other users' behavior. In terms of reputation systems, we have been investigating issues such as simulation of reputation systems and evaluating the effectiveness of reputation visualizations. We have also worked on developing novel reputation systems.

Software

BeTelGeuse: BeTelGeuse is a context data gathering tool for Bluetooth-capable platforms and sensor devices. It has been designed to be extendable to new sensors and to run on several platforms. BeTelGeuse does not analyze the collected data, but it offers ways for plugins and other programs to use the data. BeTelGeuse is published under the GNU Lesser General Public Licence (LGPL).
