A tabletop user interface called u-Table is proposed in this paper. u-Table provides a cooperative place to share multimedia data among portable devices. We developed simple methods for device recognition and fingertip detection. Users can intuitively manipulate data and devices on u-Table using their fingertips. We propose new interaction methods for the tabletop interface such as a rotational window, a rotational pop-up menu, an inertial widget, and a transformable tabletop. Then, we developed utility programs for multimedia data communications and application programs. The performance of the fingertip detection algorithm was evaluated.
