Toward In-baggage Suspicious Object Detection Using Commodity WiFi — Extensive experiments are conducted with 15 metal and liquid objects and six types of bags in a six-month period. The results show that our system can detect over 95% of suspicious objects in different types of bags and successfully identify 90% of dangerous material types. In addition, our system can achieve the average errors of 16ml and 0.5cm when estimating the volume of liquid and shape (i.e., width and height) of metal objects, respectively.

This short position paper highlights examples where progress has actually been slowed as a result, offers thoughts on incentive structures currently at play, and gives suggestions as seeds for discussions on productive change.
