Digitalizing and capturing haptic feedback in virtual prototypes for User Experience design

The term User Experience (UX) is commonly associated with interactive computer-based systems. Companies operating in the consumer market are recently discovering the importance of designing UX, and in particular multisensory UX, of any kind of system, and not necessarily high-tech products. One of the most effective ways to design UX is to enable users interacting with the prototype of the system during the design process, and in particular already during its initial stages. These prototypes should provide the same experience occurring while interacting with the corresponding real product. To this aim Virtual Prototypes (VPs) may be effectively used, especially in the early design stages when the activities are still in progress and changes are frequent. Multisensory UX can be effectively designed through VPs only if all the senses involved in the real interaction are recreated into the virtual simulation. To date, despite a growing interest of research and industry in the development and use of VPs, many applications are still limited to visual and sound simulations. This paper focuses on the use of VPs to design multisensory UX, concentrating on the introduction of the sense of touch in the simulation. The methodological approach as well as the development of a case study are described in the paper
