Mediated Tabletop Interaction In The Biology Lab Exploring the Design Space of the Rabbit Juan David Hincapié-Ramos Aurélien Tabard Jakob E. Bardram Ubicomp 2011 – Beijing, China – September 21, 2011

Related Work • Static Means – Shape and Color X – Fiducial and Magnetic Markers Orientation • Active Means – Dynamic properties – Anoto-based – IR LED diodes Y – Bluetooth + Blinking Displays • RFID-based – Triangulation – Reader Matrixes – Reader on Object Tube ID – Frame Difference Algebra

The racks are always holding the tubes.
