Handshake: Rings Exchange Contact Information

Hideaki Matsui, Dong Ho Yun, and Jea Wan Park designed a ring that allows people to exchange their contact information simply by shaking hands. The idea won the 2007 Red Dot Award for Interaction & Communication design concept.

Shaking hands is a customary greeting action. Handshake brings the action one step further by creating an information transfer function. Handshake operates when people first meet and shake hands, and the rings on their fingers gain the proximity to operate. The rings exchange the users’ information and store it while the users are shaking hands. The more people met, the more information transferred. When the users browse through the people they have met, the card displays the basic information that was stored in the ring. The power source originates from the human body temperature, so no plug is required.
