Cheating In Exams Just Got More Difficult Because Of 'PocketHound'
Gone are the days (well, we hope) when the cheaters used the 'traditional' paper-based chits to write down formulae, important answers, hints et al to secure passing marks in exams. With the world going totally 'paperless', the cheaters have adopted cell phones as a way communicating during exams. But looks like that too will soon become obsolete. United States based researchers have developed a tiny gadget that can detect cell phones and the transmissions from them. That means, when your invigilator asks you to turn-off your mobile phones and keep them away - you better follow the instructions.
The gadget is called 'PocketHound' and it's capable of determining the presence of cellular phone in its vicinity. It uses its multi-band antenna to determine the cellular phone transmissions and alerts the user if it detects any. The invigilators can quickly figure out whether there's any cell phone operational during the exam time.
PocketHound has two hours of battery life and capable of scanning all the cell phone bands. It uses sophisticated algorithms to figure out RF noise to distinguish between real phone activity and ambient RF noise. The gadget costs $500.
