The Tumulte® is a unique collective virtual reality technology developed in Angoulême. It enables users surrounded by a 360° screen to interact in real time and simultaneously with the images projected in relief using simple hand movements.

What we can offer

A scalable installation
The heart of our technology is managed by software that allows it to produce Tumulte® attractions of highly very variable sizes, from 8m to 35m in diameter.
 • Content for the Tumulte®
We design, develop and product collective virtual reality content dedicated to Tumulte®.
 • For a range of clients :
> Theme parks, museums, tourist sites
> Industrial and military simulators
> Higher education
> Digital art



Tumulte® is the result of 4 years of intense R&D work to overcome the technology barriers thrown up, in particular the fact of projecting relief in 360°.

This R&D led to the construction of a prototype in 2013, then the design of a pilot installation for the general public which was inaugurated on 29 January 2015.

But this R&D does not stop there…
