Holocaust activist seems to talk to guests at her funeral

Holocaust campaigner Marina Smith appeared able to answer questions at a funeral celebration of her life, thanks to new technology - her son has said.

Mrs Smith died in June, aged 87, but video technology, built by her son's firm, meant those attending her funeral could watch her respond to their questions about her life.

Stephen Smith said it enabled his mother to be "present, in a sense".

His company predicts many uses for its "conversational video technology".

The use of the technology at Mrs Smith's funeral was first revealed by The Telegraph.

Mr Smith, the chief executive and co-founder of StoryFile, told the BBC the technology meant, once a person had died, it was possible to have a conversation with them "as if they are there, and they will answer you".

He said it meant his mother had brought "the aspects of her life that were most important to her to the people who loved her most. And it was very meaningful to them".

His mother's words were her own, and not the creation of artificial intelligence (AI), Mr Smith stressed.
