TSA Tactile Sensation Analyzer:
The emtec TSA Tactile Sensation Analyzer in comparison to this measures the three basic haptic parameters micro-surface variations (determine the feeling of softness), macro-surface variations (determine the feeling of smoothness) and the stiffness. Besides the three, plasticity and hysteresis, which determine the recovery, and the elasticity (elongation) are measured objectively and individually by the device. From all these parameters, a hand feel value (touch, comfort) can be calculated by algorithms. The algorithms need to be adapted to the market where the tested product is supposed to be sold and to its application. Hand feel values, calculated by adapted algorithms, often show a correlation of up to almost 100 percent to the human perception.
