چکیده
Spatial navigation can be based on different, i.e. the egoand theallocentric reference frames. For successful orientation in real environmentsboth frames of reference are active and can be used dependent on therequirements of the task. To separate brain electrical activity dependent on theuse of the egocentric and the allocentric reference frame we investigated spatialnavigation in a desktop-based virtual reality where subjects can be categorizedwith respect to the preferred use of an egoor an allocentric frame of reference.Clustering on time/frequency transforms of components extracted byindependent component analysis (ICA) revealed similar oscillation patterns in awide spread cortical network associated with the use of both reference frames.However, differences in frequency modulations in parietal and prefrontal brainareas support the assumption that distinct brain areas subserve the computationof an egocentric and an allocentric reference frame during spatial navigation.

Statistical speech activity detection based on spatial power distribution for analyses of poster presentations
This paper proposes a microphone array based statistical speech activity detection (SAD) method for analyses of poster presentations recorded in the presence of noise. Such poster presentations are a kind of multi-party conversation, where the number of speakers and speaker location are unrestricted, and directional noise sources affect the direction of arrival of the target speech signals. To ...
