human behaviour detecting badges img
While the world is growing thick and fast in almost all the fields and touching new horizons of success, growing security concerns on an account of increasing terrorist activities have once again forced the security organizations to develop some effective or innovative measures to tackle such quandaries. Meanwhile MIT pollsters have popped up with special badges, capable of detecting human behavior, for attendees visiting important and sensitive offices and places. The latest card features an infrared sensor that records FACE-TO-FACE INTERACTIONS between attendant and the visitor. While a wireless radio accumulate data about closeness to other cards and forward it to a central computer, on the other hand, an accelerometer track movement, and a microphone observes the speech pattern of the participants. Moreover, a workstation in close proximity draws an instant social graph, depicting who visited whom and the duration, throughout the episode. Fairly innovative as well as impressive. It could be a real boost for people and companies facing safekeeping problems.
