How do you conduct an experimental study of perceptions?
Integrating user perceptions into product design

The study you are about to carry out includes the following steps:

• Creation of a product space, made up of products of varying performance and attributes. This set of proposals, or designs, real or virtual (using a digital mock-up) will serve as the basis for evaluation. The products must be sufficiently different to stimulate a wide sensory range in the user, yet sufficiently similar to remain within the same sensory domain.

• Perceptual measurement of the product space. This stage involves characterizing the interaction between a subject and the products in the produced space, using evaluation tests. The subject must provide a sensory response to an evaluation test, which can take various forms (quantitative evaluation, pairwise comparison, sorting task, etc.). This stage can use the tools and methods of sensory analysis (sensory descriptors, expert...
