Abstract
There is an intricate and evolving relationship between
sonification and Complex Event Processing (CEP) for
improved situational awareness. In a paper presented at ICAD
2013 [1], we introduced a series of techniques using CEP for
simultaneous sonification of both quantitative “hard” data and
human-derived “soft” data in the context of assistive
technology. The connection of CEP and sonification was
explored further in the context of a severe weather tracker that
relies on fusion of quantitative (sensor-based) weather data
along with human observations about storms and related
conditions [2]. An area of shortcoming in both of these earlier
works was the difficulty in creating sounds that represented
human sentiment about observed conditions (e.g. unanticipated
obstacles for a blind person crossing a busy street, or
impending dangerous weather conditions) in a format that
enabled intuitive listening for improved situational awareness.
This extended abstract provides an update on that continuing
research by representing human sentiment data, via the use of
vocal synthesis that is driven by Complex Event Processing.
