Introduction
• Timely response of first responders is crucial in rescue operations.
• First responders inundated with streams of data from sensors (machine + citizen).– “Emergency responders have to assimilate large amounts of
information in very short periods of time” [Cowlard et. al].• Streams of data when interpreted with domain
knowledge, results in abstractions.• Abstractions (intuitive to humans) makes first
responders respond quickly in rescue environments.

– Environment sensing• Machines with sensors
Motivation

including military reconnaissanceand rescue operations.
– Environment comprehending• Machine with sensors + perceiving background
knowledge + comprehending background knowledge

Google’s car that wonthe DARPA challenge.
• Building a rescue robot (mobile-platform) with many sensors.
• Data Collection and annotation using SSN ontology.
• Analysis to be carried out for situational awareness using perception ontology [2].
• Visualization of the emergency situation in terms of abstractions.

Perceptual Analysis
Events in environment
• Collection of data from sensors on the robot.– Position data: Observation form position sensors.– Sensor data: Observation from environment
sensors.• Annotation of raw sensor data. – Use of SSN ontology which has concepts to
describe sensors and their observations.

• Perceptual ontology used to derive abstractions from annotated sensor data.
• Domain knowledge is used to derive these abstractions.

Local
• Robot with perceptual abilities give out abstractions that are intuitive to humans.
• Demonstrated a real-time physical system that uses domain knowledge to process heterogeneous sensor data.
• Demonstrated visualization of events (as abstractions) in an emergency situation in real-time.
