Haptic touch temperature and perceived quality are closely related to each other. There is a sensory range of expectation within which a touched material must be located. Knowledge of these parameters is helpful in generating a certain perception. There is a sensory range of expectation in which the touched material can be located. If a touched material is within that range, a positive feeling is triggered. If the expected value deviates from the experienced value, irritation is caused. If a high-quality element is expected but is not perceived (plastic - steel), an impression of impaired quality is generated. This example can be applied to many controls such as buttons, volume control of a HiFi system, imitation leather, door knobs, decorative elements in the car, and many others.

Knowledge of the absolute values, the haptic touch temperature, can affect the perceived quality. This is possible without undertaking time-consuming studies with subjects with probably relative statements. Just make a measurement – the result is not influenced by the transparency, gloss or color of the material and therefore it is exact.

HapTemP generates absolute values on the Sensotact® scale. That scale was developed in extensive subject studies. It puts reference material in a quantified sequence. The HapTemp then generates a physical basis for these values and correlates them with the reference scale so that any gradation is possible. Not only the contact temperature is defined, it is also correlated with the human perception and the Sensotact® scale.
