Watch or Immerse?

Great events as concerts, music festivals and football matches bring together many people from different backgrounds and interests. In these events, people act, most of the time, as passive spectators, with little or none interaction with the artists in the event. Nowadays, there is some effort to engage people in those spaces, as well as using simple technology such as objects that can be raised on pre-defined moments or, as most recently, using LED technology with sensors. This work proposes an interaction technology for crowds in great events using mobile devices. This technology involves a dynamic and an app to redefine crowd role in those events, increasing their participation and engagement. In order to evaluate people immersion in great events, a case study has been carried out in a controlled environment mimicking a music concert. As a result, it was observed that the participants felt engaged, immersed and motivated to use the proposed technology in music concerts or even other great events and they are also willing to use their own devices as a way of an active participation.
