From: Designing a tangible tabletop installation and enacting a socioenactive experience with TangiTime
The TangiTime architectural model and components. The image shows the architectural model of TangiTime. The installation consists of a low-cost tangible tabletop capable of detecting especial fiducial codes and five physical objects to interact with the installation. All tangible objects have fiducial codes attached in their base to be detected by the interactive surface and only three of them have embedded technologies. The TangiTime system acquires images from the camera situated beneath the table, and searches the video stream frame by frame for fiducial codes. The TangiTime system detects the fiducial codes and controls the interactive visualization projected on the tabletop display, the behavior of the animations, and the bi-directional communication with the physical objects with embedded technologies through an IoT platform
