Helsinki University of Technology (HUT) is the oldest and largest University of Technology in Finland. With twelve faculties, HUT provides higher education and promotes free research in technology. Through its education and research HUT is devoted to distribute the information for the benefit of the society. HUT has participated in 160 EU-projects within the Fourth and Fifth Framework Programs.
Telecommunications Software and Multimedia Laboratory (TML) belongs to the Computer Science Department at HUT. The laboratory was established in 1995 to meet the challenges of the new rapidly growing research area. The laboratory has 5 professorships, and their main areas are “Computer Networks”, “Security”, “Multimedia” and “Virtual Reality”.
Experience and Expertise
TML is one of the pioneers of research on auralization and interactive real-time room acoustic rendering technologies. They have developed their own DIVA (Digital Interactive Virtual Acoustics) auralization system. Their advanced audio processing system is applicable also the Uni-Verse project. At the moment the EVE research group is involved also in another EU project called ALMA (Algorithms for the Modelling of Acoustic Interactions).
Short resume of the key persons
Professor Lauri Savioja, Dr. Sc. Tech., professor in Telecommunications Software and Multimedia Laboratory. He has been working for the university since 1991. He has over 40 journal and conference articles on virtual reality, the main focus being in the virtual acoustics, and room acoustic modelling. He is heading the EVE research group having 12 researchers and research assistants at the moment. The focus areas of the research group are virtual acoustics, applications of virtual reality, and human-computer interaction. He is responsible of teaching computer graphics and virtual reality in the university.
Dr. Tapio Lokki has studied electrical engineering and computer science at the HUT. He made his doctoral thesis in 2002 discussing room acoustic modelling and evaluation of the quality of acoustic simulation and auralization. Currently he has a position as a teaching researcher at the HUT.
Virtual Reality
TML is also managing the Experimental Virtual Environment (EVE) at HUT. The system is a CAVE-like virtual reality installation in which users are surrounded by 3x3 m rear-projected screens. EVE is equipped with stereoscopic projection system utilizing shutter glasses, and with a head-tracking system as well as with a 3D-audio system capable of producing moving sound sources into three-dimensional space.
