This paper reports on “TOTEM” (TOuch ThE Music), a project aiming at finding inclusive solutions to foster the d/Deaf’s participation to live music concerts. In particular, the development of a portable device that transforms live music signals into symbolic vibrations is described. A co-construction, user-centered approach supplied a list of specifications adapted to the d/Deaf and hearing users’ needs. The specifications were iteratively implemented and discussed over the course of the project, alternating between developments in the lab and in situ tests during live music concerts.
