In order to optimize the use of hand/ power tools, user differences such as the influence of user expertise must be considered in product design. Therefore, product-independent non-application-specific variables are needed to objectively capture user expertise. In sports science, the characteristics of movement are used to evaluate the training level. To what extent these variables can be used for product development is unknown. Therefore, a study with 6 male subjects was carried out to analyze correlations between efficiency and characteristics in the movement behavior of the subjects when hammering. Results indicate a clear difference between experienced and less experienced users. Moreover, the movement of the more efficient subjects was spreading less than those of the less efficient ones.
