Riot 1831@ Nottingham Castle is a year-long R&D project that began in October 2013. The exhibition aims to provoke debate, support learning about protest and rebellion through time, and encourage participation by creating a new, exciting way to tell the story of a night the Castle was attacked in 1831. The project is developing a mobile Augmented Reality (AR) cross-platform app that offers visitors an active role in creating their narrative experience. It uses object tracking technology to superimpose onto the live objects -3D real-time computer environments, animated first-person performances and sounds onto museum objects that allow the visitors to simultaneously interact and experience the events of 1831 at the exhibition.
