This investigation arises from the authors' experiences working as museums' front of house staff and mediator, observing visitors and their challenges to engage with the artwork horizontally. Our investigation concentrates its efforts on identifying a common denominator among an audience in The UK and Sao Paulo (Brazil) by testing an approach based on audio. Crossing the participatory museums studies, our experience working in museums and UX Design tools, this paper shows the research process to develop a solution for a collaborative audio tool. It shows an effective way to build a connection with the artwork by giving to the audience a tool to make the fruition of art independent and horizontally.Museal Processes. UX Design. Audio guide.
