Is human hosting essential to social touch in the public space of merging realities? This paper explores the role of hosting in art and design for mediating social touch in public space, social robotics, virtual reality and tele-matic environments. The question of whether human hosting is essential to social touch was the focus of three experiments held during performance of artistic orchestrations designed for social touch in public space for which the effects of different hosting designs have been analyzed. These internationally presented orchestrations, Saving Face (2012) and Master Touch (2013), purposefully disrupt and re-orchestrate multi-sensory connections in unfamiliar and unpredictable ways, to evoke shared reflection and shared sense making in public space, mediated by a host. Saving Face was orchestrated internationally in museums, urban public spaces and theatres, including; 56th Venice Biennale 2015; Connecting Cities Network Ber-lin/Dessau 2013; 3th TASIE Art-Science exhibition, Science & Technology Museum Beijing 2013; Beijing Culture & Art Center BCAC 2015-2016. Master Touch was orchestrated at Rijksmuseum Amsterdam 2013. This paper extends the multi-sensory interaction model for social touch described in (Lancel et al. 2019e) to explicitly include the role of a host. The question this paper addresses is whether the host needs to be human. This paper calls for future design of disrupted social touch in merging realities to consider hosting processes of shared sense making. Such design should facilitate new forms of reciprocal embodied interaction, that support descriptive self-disclosure, dialogue and shared reflection on experience of social touch in merging realities.
