Prof. Mario Botsch's team uses AI expertise to support the HOLO-VOICES project - holograms preserve the voices of Holocaust survivors.

How can memories remain alive for future generations if contemporary witnesses can no longer tell their own stories? With modern AI and holographic projection technology, TU Dortmund University's computer science department is helping to find answers to this question.

In the HOLO-VOICES project, which is being realized jointly by the Ministry of Culture and Science NRW and TU Dortmund University, interactive holograms of Holocaust survivors are being created. Visitors can ask them questions - an AI answers them by drawing on previously recorded interviews.

The data processing is being developed and supervised by a team led by Prof. Mario Botsch at the Department of Computer Science. "As a leading location for AI research, we are contributing our expertise to enable young people to have an authentic dialog with contemporary witnesses," says TU Rector Prof. Manfred Bayer.

The project combines computer science, journalism and history to make an interdisciplinary contribution to combating anti-Semitism and racism. The first exhibition "HOLO-VOICES - meet - ask - tell" will open on January 27, 2026 at the Zollverein UNESCO World Heritage Site - with the voices of Holocaust survivors preserved for eternity thanks to AI and computer science.
