This mechanism is intended for use with existing tabletop Tangible User Interfaces, providing computer-controlled movement of the physical objects on the table, and creating an additional feedback layer for Human Computer Interaction (HCI). Use of this actuation technique makes possible new kinds of physical interactions with tabletop interfaces, and allows the computer to maintain consistency between the physical and digital states of data objects in the interface. This thesis focuses on the design and implementation of the actuation mechanism as an enabling technology, introduces new techniques for motion control, and discusses practical and theoretical implications of computer-controlled movement of physical objects in tabletop tangible interfaces.","abstract_html":"The Actuated Workbench is a new actuation mechanism that uses magnetic forces to control the two-dimensional movement of physical objects on flat surfaces.
