    • Deter­mi­nation of values that corre­spond to the scale of the TouchFeel Box.
    • Deter­mi­nation of a value on the Sensotact scale for better compa­ra­bility.
    • Evalu­ation of the perceived touch temper­ature of a surface, e.g. in the context of marketing decisions

The touch temper­ature is closely related to perceived quality. When touching a material surface, we humans have a certain expec­tation of the surface temper­ature.

If the eye signals that a material is probably steel, then we expect a surface temper­ature corre­sponding to the material. If the haptic feedback does not corre­spond to the expec­tation, because the button of a stereo system, for example, is not made of steel but of coated plastic, then a cognitive disso­nance occurs.

This results in confusion and in a reduced subjective impression of quality. This example can be applied to many control elements, such as a PC keyboard, artificial leather, door knobs, decorative elements in the car and many more.

By knowing the absolute values of the haptic touch temper­ature, the perceived quality can be influ­enced. This is possible with the HapTemp by a simple and fast measurement.

Therefore, studies with distorted results are no longer necessary. The measurement result is independent of trans­parency, gloss or color of the materials. HapTemp generates an absolute value in the Sensotact® scale. This scale corre­lates with the human sensation of the touch temper­ature.


By knowing absolute values, HapTemp provides infor­mation on the perceived touch temper­ature of a surface. Product managers thus have the oppor­tunity to positively influence the perceived perception before series production and thus avoid cognitive disso­nances that can lead to customers making a negative purchase decision.

  • Shorter devel­opment times
  • No subjective studies are needed anymore
  • Optimization of subjective product quality
  • Objective, repeatable measurement result
