What are Madgets?Madgets are magnetic widgets for interactive tabletops. Like SLAP widgets, they provide the rich haptic feedback of tangible controls and use the table's rear-projection to change their visual appearance. In addition, permanent magnets attached to their base enable their flexible actuation. As low-cost, untethered, and easy-to-build controls, Madgets help maintain consistency between physical controls and their internal digital state, or to synchronize physical controls on tabletops between users at two remote locations.
Our interactive Madgets tabletop combines electromagnetic actuation with fiber optical tracking. Unlike previous actuation approaches, our algorithm decomposes complex controls into multiple rigid bodies that are linked by joints. Beside arranging objects on the table, we make use of new actuation dimensions, such as height, vibration feedback, and power transfer. A grid of fiber optics lets cameras beneath the table see past the actuation hardware. Our tracking algorithm then detects Madgets and finger touches on the tabletop.
The TeamMadgets is a research project by Malte Weiss, Florian Schwarz, Simon Jakubowski, and Jan Borchers from the Media Computing Group. It is funded in part through the German B-IT Foundation. Thanks to Helga Isenberg, Lucas Braun, Christian Remy, and Simon Voelker for the help to build the system. Special thanks to Patrick Baudisch for his valuable input to our UIST paper. Thanks to Stephan Ortmanns for designing the logo.
