This is a case study of a hearing-impaired researcher who was coparticipant in a study of learners with sensory and intellectual impairments in six European museums. The fieldwork for this project was based in London, Madrid, Oviedo (northern Spain), and Vienna, with partners and technological and university partners in Spain, Serbia, Austria, and the United Kingdom. The output from the project was improved methods of teaching and learning, the identification and elimination of barriers to inclusion, and a suite of codesigned technologies in the museums involved in the research. The methodology used for the study was an emancipatory form of participatory research, and data-collection methods included participatory feedback from monthly and bimonthly meetings, interviews with participants, recordings of participant groups, photographs of practice by the participants and of participants' practice, art-making activities, and participant diaries. This case study aims to discuss the following questions in relation to the researcher's experience of fieldwork in Madrid and London: What challenges do researchers face as researchers and coparticipants in the course of this fieldwork? How can institutions engage researchers who are members of a broad range of communities in participatory studies and practices? Central concerns in this case study include the power issues and tensions that arise between researchers and different groups of participants or individual participants, how researchers communicate with research participants with different communication needs, and the importance of remaining attentive to cultural differences when conducting participatory research in different cultural contexts.
