Abstract
In this paper, we describe some results of our study on new telecom smelling services based on experimental devices diffusing scents over networks. Usability tests carried out on the basis of two prototypes, show that adding a third sense to the existing senses available in multimedia services has a strong positive impact but requires new approach in the service design process. Since the business of scents is increasing (presonal and home fragrance, brand's smelling signature for corporate communication...), telecom applications using scents devices are broad and may address companies, professional communities as well as individuals.
