Quantifying haptics. Comparing the haptics and physical measurement of surfaces of wooden flooring
Results of the assessment by touch of the haptics and the perceived temperature of different surfaces by test persons were compared to quantitative measurements of surface roughness (SEM) and thermal properties. Humans can feel roughness very precisely and judge material type by touching a surface. The test persons were able to feel the actual surface roughness very well down to a few hundredths of a millimetre. With the oil/wax systems tested, the haptic character of the wood was retained very well. The temperature perception and in this context the heat conductivity of the coatings are important factors. It was found that the colour and structure of wood has a positive effect on temperature perception. Surfaces with film forming coatings may appear cooler because the visual effect of the coating films and perhaps also higher gloss of the surfaces may influence a person looking at them closely and touching them by hand. The film of the waterbased sealer led to a cooler perception of the surfaces compared to others, whereas the rough surface structure of brushed larch wood and untreated beech wood appeared to be warmer. The reasons for a warmer or cooler sensation of surfaces are thermal conductivity of the material, the contact area with the surface (surface roughness) and heat storage volume of materials. The low heat conductivity of wood is beneficial for a warm feel because the uppermost layers are heated up quickly by the temperature of the human body.
