There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Putting Wireless Sensing to the Litmus Test
ABSTRACT:
TWireless radios have been conventionally used as a communication platform for many years. However, communication is not the only utility of wireless signals. As signals traverse our environment, they “pick-up” information about the environment; this enables wireless sensing. If we observe the mutations the signals undergo, we can start to decode this additional information and learn more about our environment.
In this talk, I will discuss in detail how wireless sensing can enable liquid identification — a literal litmus test. Fine grained analysis of the signal helps us differentiate between a wide variety of liquids including, Pepsi and Coke, or distilled water and tap water. This has applications in airport security, detecting water adulteration in developing countries, quality assurance in the food industry, etc. Our liquid identification techniques are not an outcome of data based training or feature engineering. Instead, we measure two fundamental properties of the liquid that lead to its identification. I will also talk about my wireless motion tracking research, where I look at localization of people and objects in indoor spaces, on sports arenas, or in a battlefield.
