Abstract: The tactility of product materials is a fundamental consideration in product design. This study proposes a method and tools for assessing tactile interaction based on user impressions; furthermore, investigates how users form impressions of product materials. This study develops a method to assess tactility in interactions with materials, focusing on associations behind explicit user impressions of these interactions. The method was tested experimentally and the characteristics of these in-depth impressions explained the formation of user impressions. The specified concepts in connection with the whole concept of product material can elucidate the successful tactile interface between users and products. The materials in product design should, therefore, be selected bearing these considerations in mind. The method provides directions for the systematisation and modelling of tactual experience in computational tools to aid material selection. Furthermore, the method will improve designers' and engineers' selection and implementation of materials in products.
