Le lien à la culture renouvelé par les mobilités informationnelles

How can inaccessible cultural heritage be made available to immobile or distant audiences, to meet their cultural needs? Information and communication technologies offer instrumental responses to this new challenge. This type of resource promotes informational mobility as a substitute for real mobility.After introducing the concept of informational mobility and quickly reviewing existing solutions, the body of the article considers digital devices that do more than simply transpose a situation marked by physical inaccessibility. This is the case for the survival of certain heritages, notably immaterial, confronted with the impossibility of physical encounter due to the disappearance or death of their witnesses.The second part of the article addresses historical testimony, and illustrates it using the example of a holographic device implemented in the United States for witnesses to the Shoah. The same device was used to record and share the testimony of mine survivors in the framework of the ANR MémoMines, the subject of the third part of the article. This latter context allowed an experimental study with the public. Beyond providing a simple technical answer to the initial question, this exploratory study provides clues as to how the experience of temporal informational mobility is experienced/appreciated by the public.
