At the biological museum in Stockholm we implemented our indoor positioning platform, based on 60 Gimbal bluetooth beacons. On top of that we built a sound platform, in Unity. Tracking the visitors location in realtime plus the vertical and horizontal orientation of their head gave us the the ability to link sound effects with objects in a 3D environment, creating an immersive virtual soundscape.
An interfaceless app running on top of the visitors head, first introduced them to what they were about to experience. Once inside the rotunda, it reacted to the tiniest head movement, creating a completely new and fascinating way of interacting with the surrounding.
60 bluetooth beacons pulsing their signals every 100 milliseconds, creating a dense trilateration grid within which we position the user with an approximate 0.5 meter accuracy.
