Interactive floor or wall projections in the space allow the visitor to become part of the exhibition or part of the story.
The only installation that doesn't "waste" space is space, but can be used through the installation or passageways and hallways.
An example of a simple interaction where the movement of one or more visitors interacts with the presentation. For example: water frowns on the passage, ice breaks at the place where it is walked, there are traces on the floor, etc.
Interactive floors also allow for much more complex interaction, so games based on participants' movements in projection can be played.
Interactive projections can be combined with other types of installations, such as the video wall on the example of this Nike store in London. We used the projection as an invitation to interact with the installation. The floor projection and the video wall are one complete installation managed with the IR motion sensor.
