Characterization of the perception of a hybrid product integrating components from contradictory product universes in design: application to sport-health products.

The aim of our research is to propose a method to characterize the perception of a so-called sport-health hybrid product.
Indeed, the user experience associated with a product has become, nowadays, a major differentiator among the competition and can greatly influence the success of a product. Users / consumers are no longer just looking for a functional tool, but also a tool that is easy to use and that gives them satisfaction throughout its use. This last aspect, user satisfaction, has become an important industrial issue. The aim is to provide the best possible user experience and thereby improve the chances of the product being successful. It depends in particular on how the product is perceived.
However, in some cases, designing the way a product is viewed can be complex. This is particularly the case with hybrid products that combine characteristics from different product areas. The company SC-Ergomedical experienced this difficulty by noting that the hybrid sports-health products developed were not fully understood. Indeed, they were perceived either as sports products or as health products, but never together. It is clear that this makes them less accepted by users / consumers. This perception gap results both from the dialogical nature of the product universes of sport and health and that the perception of such products depends on their contexts of contrary uses but also on a missing semantics reflecting the identity of the sport-health hybrid product.
In order to reduce this perception gap and improve the understanding of hybrid sport-health products, we propose in this thesis a methodology based on the Affective Engineering approach. The results observed then make it possible to build a design space to characterize the perception of a sport-health product. Indeed, the first two experiments carried out made it possible to define a sport-health semantics as well as the influence of contexts of contrary use which conditions the perception of these products. The third allowed us to characterize the attribute space of sport-health products and link it to the predefined semantic space. All three experiments led us to the creation of the design space characterizing the perception of a sport-health product.
This design space provides a guide for designers to develop hybrid sport-health products and reduce the perceived gap. Indeed, via this space, it is then possible to recommend attributes produced from a sport-health semantics in a context of use of sport and / or health, to evaluate the sport-health values of a solution or a final product or to explore combinations of sport-health product attributes and visualize the resulting values.
These different possibilities can be used in a design assistance tool for hybrid products like the one we propose in this manuscript specific to the design of hybrid sport-health products.
