Softness, roughness and stiffness are the three basic haptic parameters, which determine the human hand feel. But, in comparison to the human hand, the device provides these three parameters as individual values. By the help of special algorithms, these three single parameters can be combined to so-called hand feel (HF) values. With the right mathematical model, a correlation to the human expectation of up to almost 100 percent is possible.
The emtec TSA Tissue Softness Analyzer is already subject of a released TAPPI Technical Information Paper (TIP). The critically peer-reviewed technical specification document investigates the specialized measuring instrument that is able to simulate the sensory properties of the human hand when touching tissue paper products. TAPPI TIP 0808-07, titled “Objective Determination of the Haptic Properties of Tissue Products, Technical Information Paper TIP 0808-07 (2021)” covers the theoretical background of haptics, how the TSA device measures the three basic parameters for determining haptic feel, and discusses application possibilities for the paper manufacturing process and quality assurance.
