Abstract

The correct functioning of the haptic system controls the human abilities of tactual perception and manipulation. For both tactual sensory information and motor performance, contact force is probably the most important variable in performing manual tasks in real or virtual environment. When a hand is pressed against an object the contact forces are sensed. Through conditions involving varying force magnitude, muscle system and experimental method, the Just Noticeable Difference (JND) in contact force is about 7%. In the paper, comparisons are made in the ability of the subjects to track a particular target with normal and anaesthetized fingertips. Discussed are the effects of various parameters and conditions on the absolute error in tracking.
