LeviCursor - Dexterous Interaction with a Levitating Object

Explore a groundbreaking conference talk on LeviCursor, a method for dexterous interaction with a levitating object in 3D space. Delve into the innovative technique that allows for smooth and continuous movement of a physical, levitating particle in any direction. Learn about the optimization of transducer phases, precomputation techniques for rapid phase determination, and the interpolation scheme enabling sub-millimeter accuracy control. Discover the particle stabilization mechanism ensuring the levitating object remains in the main levitation trap. Examine the results of the first Fitts' law-type pointing study conducted with a real 3D cursor, comparing user performance to that of a mouse pointer. Gain insights into the hardware setup, motion capture techniques, and potential future applications of this technology. Presented at the ACM International Conference on Interactive Surfaces and Spaces in Tokyo, this 23-minute talk covers introduction, problems with linear interpolation, optical motion capture, hardware implementation, evaluation methods, and concluding thoughts on the LeviCursor system.
