The Haptic Scissors


The objective of the Haptic Scissors Project is to simulate the feeling of cutting tissue. This is useful for surgical simulators or the equivalent of "flight trainers" for doctors. Motors attached to the scissor handles simulate between-the-fingers forces, and translational forces.

We have simulated liver, skin, and tendon tissues, and also rendered friction between the blades to make the haptic scissors feel as realistic as possible.
