Hysteresis data, residual force and haptic sensitivity data

The dataset 'sensitivityThreshold(haptic feedback).zip' contains the results of a haptic feedback sensitivity study comparing a novel laparoscopic grasper with 2 conventional graspers. Also grip preference of each participant was stored.The instrument sensitivity was validated by measuring the level at which participants could discriminate force differences applied at the grasper tip with an increasing force level, while the subjects were holding the new instrument and a conventional grasper at the handle grip. The force was increased and subjects reported at which force level they were able to feel an increase. The dataset 'balancingError.zip' consists of 10 repetitions of measurements on a balanced compliant laparoscopic grasper. It is the instrument's unloaded residual balancing error measured on a linear stage with load cell.
