SYSTEM BLOCK DIAGRAM
The evolving capability and portability of smart phones has facilitated reliable access to the resources of the internet from nearly anywhere in our society. While incorporation of these devices in our day to day tasks can provide great efficiency and utility, there are specific settings where the use of these devices is unwelcome.
For example, the integrity and fairness of today’s popular academic and professional assessment metrics (SAT, GRE, MCAT, GMAT, college exams) is greatly compromised by test-takers exploiting unauthorized use of smart phones during testing. The current established solutions are not as effective as they could be.
The Sitting Duck project delivers a working system that demonstrates an automated tool for detecting, locating, and providing objective evidence of unauthorized cell phone usage within a standard testing environment. This design utilizes a phased antenna array and methods of radio frequency interferometry, real-time signal processing, and video processing.
