The presenters introduced Red Tacton, a new technology that uses the human body as a network transmission path. It works by inducing a weak electric field on the body surface and using an electro-optic crystal and laser to detect changes in the field caused by a transmitter. Key features discussed include using various body parts and movements for communication and applications like interactive advertising, device pairing, and security. Prototypes developed so far were mentioned as were safety measures to ensure insulation from the electric field.
