The ability to detect mental states, whether relaxation or stressed,
would be useful in categorizing places according to their impact
on our brains and many other domains. Newly available,
affordable and dry-electrode devices make
electroencephalography headsets (EEG) feasible to use outside the
lab, for example in open spaces and shopping malls. The purpose
of this pervasive experimental manipulation is to analyze brain
signals in order to label outdoor places according to how users
perceive them with a focus on ―relaxing and ―stressful mental
states. That is, when the user is experiencing tranquil brain waves
or not when visiting a particular place. This paper demonstrates
the potential of exploiting the temporal structure of EEG signals
in making sense of outdoor places. The EEG signals induced by
the place stimuli are analyzed and exploited to distinguish what
we refer to as a place signature.
