Gli strumenti per lo studio dei pubblici nei musei: strumenti tradizionali e biometrici

The research focuses on the analysis of the characteristics and applications of the tools used by museums to understand their audiences. Among the main objectives of museum institutions are the preservation of collections and their communication. For this reason, museums are in constant connection with the external environment. The final recipients of the message conveyed through the artworks are situated within a contemporary and future-oriented dimension. The testimonial value of the objects preserved within museums concerns society as a whole. The institution therefore plays a central role in social dynamics, acting as a custodian of knowledge that is continuously committed to disseminating and generating new understanding. In order to effectively convey their content and adapt it to the needs of different categories of users, museums must acquire a deep knowledge of their visitors. Audience research practices have become common in the investigative and evaluative operations carried out by museums, with varying levels of awareness regarding research methods, data management, and data use across different institutions. Traditional tools such as questionnaires, observation, interviews, and focus groups are widely used in visitor studies conducted within institutions and discussed in the related literature. Alongside these, in more recent years, devices of clinical origin have emerged that analyze the visitor experience from the perspective of individual physiological reactions, monitoring responses through the measurement of biometric parameters. The following sections examine the characteristics of each tool belonging to these two categories, highlighting their potential and limitations. The integration of different types of instruments may allow for the collection of the most comprehensive possible information regarding the impact of the museum experience, gathering data of various kinds that together outline the complexity of the visitor’s response to cultural heritage. To deepen the insights obtained from the literature, the research also includes reflections from museum institutions that have hosted experiments involving the collection of psychophysiological data. These contributions help to clarify the current state of research in this field, as well as the opportunities and limitations perceived by museums—aware of the importance of knowing their audiences—in integrating such devices into their common practices.
