Hardwood are assumed to influence visual-tactile perception due to various components, such as wood vessels. It is hypothesized that there is difference of impression between wood working experts and non-experts when evaluating hardwood. We prepared three-types of hardwood samples with different vessel depths and investigated the difference of impression between experts and non-experts by using evaluation tests and measuring hand movements. As results of the evaluation tests, non-experts were influenced by the contrast due to difference in vessel depths and there was difference of impression between visual and tactile conditions. However, experts were less affected by the contrast and did not take wood vessels into consideration in their evaluation. As results of hand movements when assessing wood samples, the movements of experts were constant and stable, but those of non-experts were not. Therefore, it is considered that the impression of wood containing vessels are different between experts and non-experts.
