ABSTRACT
This research looks at the human ability to perceive haptic information when using Minimally Invasive Surgery (MIS) tools. In the simulation of MIS it is important to understand what haptic information can be perceived by a user. Understanding what can be felt allows the force feedback system of the simulator to be optimized.

This paper describes research on human perception of haptic information in minimal access surgery (MAS) instruments, for use in a MAS simulator. Understanding the thresholds of human perception is important in determining which haptic information must be provided for realistic feedback and which information can be ignored without compromising the immersive quality of the simulator. Initially this research has determined the limits of perception for non-continuous change of force amplitude and frequency in a scissors-grasping position.
