Abstract: This paper proposes a unique approach within the field of prosthetic devices: a new user-centred data-collection methodology based on the Repertory Grid Technique (RGT) for the aesthetic design of below-knee prostheses. The innovation of this methodology is to propose a measurable approach guiding the designer to detect latent emotional needs of interviewed prosthetic users to be translated into measurable aesthetic issues to reproduce in their customized devices. This work is situated within the Kansei Engineering framework and is part of a more comprehensive study for the revision of aesthetic prosthetic design. The data of this paper are based on face to face interviews and the results were translated into a set of design principles and elements classifying the statements of the users. This methodology aims to stand as an initiative for a new design system for the improvement of the emotional User Experience of prosthetic users – and to consequently provide products to be positively accepted by the users for the improvement of their body image.

Keywords: Visual prosthetic design, emotional design, Personal Construct Psychology, prosthetic user needs
