TacTable develops new ways for people to interact with media and with other people.

We create state of the art experiences using our patented technology to make large display surfaces come alive through Multi-Touch sensing. Our interactive tables and walls recognize and track dozens of simultaneous finger and object interactions enabling people to touch and interact naturally with retail content, ancient antiquities, art or media like film and music – making memorable experiences out of interactive digital content.
