Dr. Sheryan Sen, an associate professor at Purdue University, shared his team's research paper titled, "Enabling New Interaction Modalities by Communicating Strictly Through Touch Using Electro-Quasistatic Human Body Communication."
Dr. Sen argues that wearable devices that use Bluetooth could use our body as a wire to send information securely because the signals are not getting radiated, but only transferred by touching. Using this technology you can open a computer, a home/car door, also create a second-factor authentication by just toughing with your finger. Also, it can transfer my contact information through a handshake.
As far as the applications of this technology are concerned, the possibility includes augmented reality, virtual reality, basically anything you think Bluetooth is used today around the body. This technology can replace Bluetooth technology to connect/transfer data with Human-computer Interaction utilizing low frequency Electro-Quasi Static Human Body Communication.
Currently, the team sees huge application space and multiple different large companies as well as startups have shown interest including the touch-based-ID technology and they are working with them to develop this technology and bring it to market.
