This research deals with the challenges of audience engagement that such endeavor represents. In particular, we address the use of instructional signage as a way to increase visitors’ participation, through a field experiment research approach (taking place on a natural occurring environment) combining practice-based research, observation and a questionnaire. An interactive art piece using QR Code technology was created as part of the experimental procedure. Results showed that the interaction using smartdevices and QR Codes was successfully accomplished and audience engagement significantly improved when instructional signage was used.EnglishHuman-centered computingEmpirical studies in HCIUser centered designEmpirical studies in ubiquitous and mobile computingEmpirical studies in interaction designtext::conference output::conference proceedings::conference paper
