The following examples illus­trate the differ­ences of different materials.

Material A

This material is an artificial leather. to the eye already a structure is recog­nizable, which allows conclu­sions about the haptic experience. However, only with the measurement results a repro­ducible and objective image is possible.
In practice, this can mean, for example, that in the production of artificial leather seats for passenger cars a very specific effect can be achieved, if the parameters are known. So the slippery factorcan be decisive for the purchase decision, the seats should be designed for a pleasant sitting feeling not too “slippery”, but also not too “sticky”.

Material B

It is already visible that this artificial leather has a different structure. The measurement results are corre­spond­ingly different compared to material A. For our customers, exactly this measurement relia­bility is so important and useful, because a pure eye diagnosis can be useful in the practical imple­men­tation never cover the descriptors of our measure­ments – we would like to remind at this point once again that every person is different perceives.

Material C

This much smoother imitation leather “tells” a different story again. The eye already perceives a relatively smooth surface, and the Measurement results confirm this: the macro roughness is in a very low measuring range.

Material D

This material is completely different from those examined before. It is a very smooth surface, which is used for food packaging. The measure­ments show which macro– and micro-​​roughness must be given to achieve such a haptic experience. Thus our customer can choose the chemical ingre­dients as long as the measured values corre­spond to our measurement.

Conclusion

These four examples from our daily practice illus­trate how essential the acqui­sition of surfaces for the process of product devel­op­ments are. At this point we would like to once again emphat­i­cally point out that with the help of the haptic finger­print it is possible to combine materials and surfaces with each other and compare it with a reference, for example. However, an absolute evalu­ation is currently not yet in our offer.
