Qualitative Interactive Experiences

Interactive Experiences in im.ve L-Shape(PhD Project Matthias Haringer)


Continuous visual, auditive, olfactoric, and haptic outputs, which surround the user as completely as possible, allow the creation of believable virtual environments. Experiences in those multi-sensoric virtual environments are called interactive experiences in this context. The focus in virtual reality has been mainly on technical issues. This complicated the use and the acceptance of those environments. This work is intended to help concentrating on the user and to make the impact of the system on the human qualitatively comprehensible. One task is to examine this interactive medium in comparison to other media that are researched in a more complete way. As a result special methods are to evolve, which evoke specific reactions. To be able to examine and evaluate the impact of those environments on the user in a second step, not only self-assessment during and after the experience have to be used. Direct physiologic measures (visual, auditive, bio-physiological, etc.) help to interpret the user state directly. Applying knowledge discovery methods to those measures, the signals can be used to interpret and categorize the reactions of the user to the environment. In a last step the interactive circle is being closed. The acquired knowledge is returned directly to the virtual environment. Thereby, the system is able to use the qualitative reaction of the user to conduct instant changes in the virtual environment and to optimize the interactive experience for the user.

Up to now the different types, the acquisition, and the basic processing of bio-physiological signals have been investigated and a prototype of a general framework for measuring, interpreting, and calibrating affect from different sources and expressing the results in a general user state model, has been implemented. For emotion elicitation an approach for interpreting filmic emotions has beenadopted to interactive applications and is currently implemented.
