Life-Size 3D Projection and Voice Recognition Helps Share and Immortalise the Stories of The Holocaust Survivors


The National Holocaust Centre and Museum in Nottinghamshire aimed to capture individual testimonies, secure artefacts and gather historical information, to bear witness to the atrocities of the Holocaust.

Bright White, an innovative and creative design consultancy, were responsible for the filming, software development and integration, with Electrosonic subcontracted to engineer, deliver and install the presentation system and a specialist interactive developer, D3t, subcontracted to deliver the speech recognition technology. 


One of the main challenges facing Electrosonic was how to project a life-sized 3D image within a relatively small space, to produce a stereoscopic presentation as though the survivor was in the room with the audience. 

In addition, holocaust survivors were interviewed and filmed by Bright White, generating over 1,000 responses. These learning outcomes needed to be flexible in their delivery, so they remain engaging, and to satisfy enquiring minds. 


Following extensive testing at the manufacturer’s facility in Manchester, a 1700mm x 1700mm ScreenTech SX-Pro-X polarization system provided the quality necessary, given the space restrictions, via a rear projection screen. This also allowed the use of special viewing glasses which are simple for the audience to use and minimise ongoing running costs.

To make the presentation as lifelike as possible, we used a system which responded to the spoken word from the audience’s questions to then cue the most appropriate/ audience age or level of understanding response. This huge ‘library’ of audio-video sequences was stored on a DVS HYDRA 4 GTX980 server. A conventional front projection screen was used over the 3D display to support the main presentation as well as making the room usable for other events.

A high-end sound system was essential to give clarity to the presentation and to clearly capture audience questions.


Through the power of personal story-telling, the centre ensures immortality to these survivors and their stories for generations to come. The AV technology brings the story to life and provides an engaging ‘human-to-human’ connection, giving visitors a deeper understanding and learning experience.
