Toward an optimal quantitative design method integrating user‐centered qualitative attributes

Abstract

The determination of product features, which can be seen as design specifications, is a crucial problem that must be carried out upstream to quickly validate the product configuration according to some attributes in relation to the user perception. To this end, the design methods must evolve toward an analysis compatible with various kind of data that can be qualitative or quantitative. In this paper, a new approach is introduced able to take into account various kind of information in order to determine some quantitative design specifications in accordance with the users perception. This is done through a mathematical formulation that exploit different types of data coming from sensory analysis and physical quantities. This mathematical formulation is then used in an optimization procedure that takes into account a preference order over the sensory attributes. The solution of this optimization problem gives thus the best user‐centered specifications that must be used for the conception of the final product.

Effect of material properties on emotion: a virtual reality study

“…The influence of vision on other sensory modalities has also been very often demonstrated ( Rock and Victor, 1964 ; McGurk and MacDonald, 1976 ; Pavani et al, 2000 ) and more particularly when it comes to evaluating the appearance of a material ( Power and Graham, 1976 ; Lederman et al, 1986 ). Vision is the dominant modality when buying a product, because it is on the basis of visual information that the consumer compares and evaluates the products present on the market ( Bertheaux et al, 2019 ). This particular sense allows us to make perceptual decisions by evaluating the aesthetics, quality, attractiveness of an object.…”
