1. What is Dimensions in Testimony?

USC Shoah Foundation developed the Dimensions in Testimony interview, an interactive biography, to give people the opportunity to have conversational experiences with survivors of the Holocaust and other witnesses to history, far into the future. Each specially recorded testimony enables viewers to ask questions of the survivor and hear responses in real-time, lifelike conversation.

2. How does Dimensions in Testimony work? How is it recorded and how does it play back?

The Dimensions in Testimony interviewee is recorded in a green-screen environment surrounded by cameras and in front of a microphone. The interviewer asks questions. Each answer is recorded as a separate video clip. About 1,000 questions are posed – and answers given. This results in a list of responses that can be prompted by questions posed verbally by audience members.

Using natural-language technology, the Dimensions in Testimony system transforms asked questions into search terms. The system then matches the search terms to the most appropriate interviewee response to your question and plays back the associated video clip, resulting in a conversational-like experience.

The system logs every question and answer. To improve the accuracy of the system, trained staff at USC Shoah Foundation periodically review the system logs to make sure the most appropriate answer was chosen for each question. When necessary, staff manually link to the more appropriate response. As a result, the quality of the system improves with every question asked. The results are not immediate; rather, improvements take several days or weeks to process.

3. Is Dimensions in Testimony meant to replace speaking to a Holocaust survivor?

Nothing can replace the ineffable, dynamic interaction between two human beings. Dimensions in Testimony is a different type of engagement meant to preserve the opportunity to have a dialogic experience, and to facilitate the documentation and sharing of survivors’ lived experiences as they remember them in their own words.

4. Why is there a need for such an approach?

Dimensions in Testimony is an effective way to approach a public engagement with people in numerous museum settings to enable them to be agents in their own learning. Dimensions in Testimony encourages audiences to be active participants in driving the direction and nature of the interaction based upon who they are, and in what they are interested.

5. Are Dimensions in Testimony interviews holograms?

What you are seeing is a 2-dimensional display of video clips rather than a hologram. Holograms, or 3-dimensional videos, do not yet exist. However, research and development is being done at a handful of institutions around the world to develop 3-dimensional video projection, and USC Shoah Foundation has worked with leaders in the field of 3-dimensional video capture, referred to as volumetric capture, to ensure that we are future-proofing our filming so that the Dimensions in Testimony interviews can be projected as holograms when that technology is available. USC Shoah Foundation developed and built one of the first-ever mobile volumetric capture filming rigs.

6. What is a Pepper’s Ghost holographic display?

Some of our museum partners have installed a holographic Pepper’s Ghost theater for their visitors to interact with. Pepper’s Ghost displays are visual illusions that use lighting, specialized glass or “mirror film”, and high-definition projection to give the appearance of depth to 2-dimensional videos, making it seem like a 3-dimensional hologram.

8. Is Dimensions in Testimony available in classrooms?

Yes, classrooms can access Dimensions in Testimony through USC Shoah Foundation’s education platform IWitness, which offers lessons on the Holocaust using primary and secondary sources and active learning experiences enhanced with the interactive biographies of Holocaust survivors Pinchas Gutter and Eva Kor. Dimensions in Testimony in Education helps students develop a deepened understanding of the Holocaust and its human impact, as well as reflect on the importance of active citizenship.

Dimensions in Testimony was developed in association with Illinois Holocaust Museum and Education Center, with technology by USC Institute for Creative Technologies, and concept by Conscience Display.

Integration in IWitness is made possible through the generous support of The Snider Foundation.

9. What assurances are made to ensure that Dimensions in Testimony is ethically produced and displayed?

Since the concept was developed in 2010, Holocaust survivors have been intimately involved with the Dimensions in Testimony development process, and several served on the initial consulting committee. Their guidance has shaped the principles that govern all aspects of the Dimensions in Testimony program.

Dimensions in Testimony is often understood through its technology, yet USC Shoah Foundation sees the technology as secondary to the collection of survivor and eyewitness stories.

The research and interview phase of the project is highly collaborative between the USC Shoah Foundation team, the interviewee, and the family of the interviewee. Whenever possible, the team meets in-person with the interviewee and family members to develop strong professional and personal relationships that will enable the interviewee to feel comfortable answering about 1,000 questions. During the interview, it is the interviewees themselves retain control of the interviewing process, so they can take breaks, stop recording and make other requests as needed. Dimensions in Testimony interviewees’ family members and other members of their support group receive an open invitation to the studio as they tell their story. The Dimensions in Testimony team members and the interviewees often eat meals together, and make sure to spend informal time together talking, laughing, crying, and even singing! Life-long bonds are often created as a result of the interview process.

During the post-production phase, USC Shoah Foundation takes care to not edit, alter, manipulate, or censor any response the interviewee gave. The Dimensions in Testimony post-production methodology has been entirely created to preserve the integrity of the interviewee’s voice, a promise made to the interviewees and their families.

We also closely monitor the exhibitions, which are governed by formal agreements to ensure that partner institutions present Dimensions in Testimony as intended.

10. How can I nominate someone for Dimensions in Testimony?

USC Shoah Foundation welcomes the opportunity to work with survivors and families who would like to share their stories, but is at capacity and therefore unable to record additional Dimensions in Testimony interviews at this time.
