The transmission of memory seems to be an obsession of our time. This issue has been addressed by different disciplines and approaches. Design, as a discipline that contributes to the enhancement of culture, can help to expand the horizon of memory studies, but so far this issue is still undefined and blurred. Mnemosphere project, through an interdisciplinary approach, investigates the ways in which the memory of places is designed and communicated through experiential spaces capable of stimulating emotions. The research proposes a dialogue between communication design and exhibition design, in the atmospheric and aesthetic dimension, with emphasis on the translation of content into a system for the understanding of the mnestic space set up. This is done with special attention to the topics of emotions, chromatic perception, and the design of temporary spaces and services. The research first considers the articulation of a common lexicon regarding the memory of places, atmospheres of spaces and atlas of emotions, among others. Then, the project analysis devices for activating the memory in exhibition spaces, through data collection and defines parameters for the design of future spaces related to memory and emotions. The result is the collective construction of an archive of visual materials for the concepts proposed. This is being done through an open call that has been spread online through the project's platforms. The shared archive and results will be available online to contribute for a further perspective on design studies connected with memory and spaces.
