The use of interactive technologies in museums and cultural exhibitions has attracted a reasonable interest both from academia as well as from the industry itself. Technology today provides exciting new possibilities for creating more appealing museum experiences, since we can exploit the wow! factor of innovative interaction styles – like gesture-based interaction – to create an engaging experience that facilitates the learning process, or at least is intended to facilitate that process. Expo Zaragoza 2008, Porto Moniz Interactive Science Centre, Cultural Tourism Exhibition, and other tourism and culture-related events. These were some of the main projects of Wow!Systems, a spin-off from the Univ. of Madeira that focuses on technology that really approaches visitors to digital contents. From these case studies, some guidelines were withdrawn, concerning the implementation of these kinds of systems, namely the importance of the final physical installation and how adequate is the content to be displayed. The way visitors reacted to the interactive installations was also studied, as a learning experience and as an added value to the context where the installation was placed.
