Abstract
The touch-feel sensation of product surfaces arouses growing interest in various industry branches. To entangle the underlying physical and material parameters responsible for a specific touch-feel sensation, a new measurement system has been developed. This system aims to record the prime physical interaction parameters at a time, which is considered a necessary prerequisite for a successful physical description of the haptic sensation. The measurement setup enables one to measure the dynamic coefficient of friction, the macroscopic contact area of smooth and rough surfaces, the angle enclosed between the human finger and the soft-touch surfaces and the vibrations induced in the human finger during relative motion at a time. To validate the measurement stand, a test series has been conducted on two soft-touch surfaces of different roughness. While the individual results agree well with the literature, their combination revealed new insights. Finally, the investigation of the haptics of polymer coatings with the presented measuring system should facilitate the design of surfaces with tailor-made touch-feel properties.

To the authors’ knowledge, there is no system like the one in the presented study that combines the simultaneous measurement of the frictional and normal forces, the gross contact area, the apparent finger pad ridge contact area, the vibrational data and the angle enclosed between the human finger and the counter surface on smooth and moderately rough surfaces in a single measurement
The quality and accuracy of these measurements is very important for the prediction of haptic properties and it is needed for each sub system
Summary
Introduction of a New InSitu Measurement System for the Study of Touch-Feel RelevantSurface PropertiesThomas Ules *, Andreas Hausberger , Michael Grießer , Sandra Schlögl and Dieter P. To entangle the underlying physical and material parameters responsible for a specific touch-feel sensation, a new measurement system has been developed. This system aims to record the prime physical interaction parameters at a time, which is considered a necessary prerequisite for a successful physical description of the haptic sensation. The investigation of the haptics of polymer coatings with the presented measuring system should facilitate the design of surfaces with tailor-made touch-feel properties. The design of surfaces exhibiting a desired touch-feel has become a major issue in many industry sectors [1] These comprise automotive interiors, consumer electronic compliances and fast-moving consumer goods to name only a few. Given that a comprehensive understanding of touch-feel is available regarding the underlying physical and material parameters, tailor-made touch-feel surfaces can be designed; the touch-feel of surfaces can be predicted; and an objective classification can be achieved, introducing a sound basis to expressions such as “froggy,” “velvety” and so on
