Haptic Feedback Systems for Virtual Surgical Training
Quick fact
Some surgical simulators can replicate the feeling of a needle piercing different tissue layers with such realism that trainees report their heart rate increases as if performing on a real patient.
Why this is interesting
Imagine learning to perform delicate surgery by practicing on a virtual patient that 'feels' real—your scalpel meets resistance, tissues yield, and you feel the subtle pulse of a blood vessel. How does a machine make you 'feel' something that isn't there?
