The paper presents a technical and dramaturgical concept of two in-teractive installations proposing a complex dramaturgic approach to physically and emotionally immerse an audience. The concept was firstly presented as “Memorial for survivors and victims of holocaust” in 2011 in Prague, Czech Republic. The first installation is based on a technique of life illusion applied on a life-size statue, while using a combination of video portrait and video mapping techniques. The second installation offers an interactive presentation of historical photos and videos. By physical movement, an audience enters a visual 3D space with multimedia gallery arranged in historical order. The dramaturgy of both installations depends on presence and active movement of an audience, and aims to create an immersive space and personal relationship to presented story. The human-computer interaction (HCI) system was developed to propose alternative forms for active and/or passive informational behaviour of public museum exhibits and educational projects.
