Abstract: The identification and implementation of user requirements are significant issues in product development. For these purposes potential end-users are often invited to evaluate product concepts by different types of product representations, e.g. sketches, mock-ups and computer-based visualisations. However, little is known how they can affect the understanding of the product concept. This study aimed at exploring whether desktop-VR made a difference to end-users? understanding of products compared to sketches and real products. The results indicated that there were generally small differences in the end-users? understanding between the sketches and the desktop-VR. Key aspects such as scale and interaction seemed important to enhanced understanding. Additional factors to understanding of product concepts were the end-users? prior product knowledge, which seemed to have compensated lack of information in the product representations, and prior product representation knowledge. The end-users? limited product representation knowledge appeared to shift the focus from the product to the representation of the product, which call for consideration when choosing product representations in product concept evaluations.
