In large scale surveillance applications, coherent presentationof data coming from myriad sensors becomes a problem.For example, tasks such as "locate an intruder" areno longer easy when the user is facing a room of monitorsconnected to hundreds of cameras. Therefore, there is aneed for a system that allows the user to easily navigate thedata space. Due to the scale of the application, such systemsshould also be robust with respect to hardware and softwarefailures, as well as to varying bandwidth conditions.Our strategy is to first build software units that providesensor abstractions (e.g., location of a person, noise levelof a predefined region) to lessen the burden of dealing withindividual sensors from the user. Second, we project this abstractsensor information into an augmented virtual realityinterface for presentation to the user. The AVR interface offersa common medium to display abstract information constructedfrom multiple sensors, as well as allowing accessto raw sensor information such as video streams, or a mixtureof both. Also, the AVR interface can synthesize viewsnot serviced by the physical cameras. The sensor abstractionand the smooth transition between sensors enable theuser to intuitively navigate the data space. Further more,through this interface, the user can dynamically reconfigurethe system resources. We will demonstrate three scenarioshighlighting the above mentioned features.
