New Delhi: A group of four students in Bengaluru came up with an earphone that can detect pain and send SOS messages in case of emergency.
The idea was the brainchild of four engineering students — Nitin Vasanth, Fausya Amalh, Athul B Raj and George Mathew.
The students started working on the idea after one of their friends faced sexual harassment. The episode motivated them and they came up with the innovation that can be a life redeemer in times of difficult times.
According to a report in Economic Times , the students have come out with a working prototype earphone-shaped electroencephalogram, commonly known as ECG, device which uses four electrodes that go inside both ears. It samples data and feeds it to the smartphone that runs an app developed by the students.
“The device uses four electrodes that go inside both ears. It samples data and feeds it to the smartphone that runs an app we’ve developed. The app then processes the data with algorithms we wrote,” Mathew told ET.
“Once a panic signal is detected, there’s a 10-second gap to dismiss it. Then, it sends out alerts,” another student Raj said. He pointed out that in many cases, attackers snatch the phone away. “That’s why our system sends the alert to a server.”
Talking about the challenges that the group faced, Mathew said that it was difficult to simulate panic.
“You can do it partially with virtual reality headsets or by getting people to jump. Still, it’s not real panic. We tested the device on a lot of people to drastically bring down the false positives,” Mathew explained.
