Magnetic Levitation Gives Computer Users Sense Of Touch

ScienceDaily (Mar. 5, 2008) — Computers, long used as tools to design and manipulate three-dimensional objects, may soon provide people with a way to sense the texture of those objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University.

Why use such "exotic" means for facilitating haptic interaction? We believe there are several advantages, including:

  • Single moving part with 6 degrees of freedom

  • Zero static friction

  • Zero mechanical backlash

  • High position and force bandwidths

  • High position resolution

  • Low perceived mass

  • Very wide range of stiffnesses possible

  • Mechanical simplicity, no tight tolerances
  • CAD representation of new magnetic levitation haptic interaction system
