Toward Hazard Aware Spaces: Knowing Where, When and What Hazards Occur

While considering all existing hazards for humans due to (a) natural disastrous events, (b) failures of human hazard attention or (c) intentional harmful behaviors of humans, we address the problem of building hazard aware spaces (HAS) to alert innocent people. We have researched and developed components of a prototype HAS system for detecting fire using wireless "smart" micro electro-mechanical systems (MEMS) sensors, such as, the MICA sensors, and spectral cameras, for instance, thermal infrared (IR), visible spectrum and multi-spectral cameras. Within this context, my presentation overviews technical challenges and prototype scientific solutions to (1) robotic sensor deployment, (2) localization of sensors and objects, (3) synchronization of sensors and cameras, (4) calibration of spectral cameras and sensors, (5) proactive camera control, (6) hazard detection, (7) human alert, (8) hazard confirmation, and (9) hazard understanding and containment. The work presented will also include theoretical and practical limitations that have to be understood when working with novel technologies.
