I have just managed to project several holograms of Leo as the refugee into my very messy studio/office along with the binaural recording of the actors’ narrative (the same as in the video). It is best listened to with headphones.
I have spent several days in the Advanced Digital Projects space at Central St Martins trying to do this in Unity (with a lot of help). But managed do produce this on my own this afternoon at home. So am very pleased with the outcome. The holograms can be positioned anywhere in the exhibition space and seen through the HoloLens.
