Provoked by numerous art-less walks during the pandemic, our Open Air Gallery AR project is a smartphone-based locative media platform to display digital galleries and music albums with gamified engagement. It is a “gallery game,” a new type of interactive multimedia for virtual exhibitions in nature or a park. Geri Hahn Art: Living Out Loud AR (2024) features the art of an artist-synesthete from New Jersey, who uses her cross-sensory synesthesia as a creative inspiration. The app includes music by Svetlana Rudenko (Piano) and Mads Haahr (Synths), composed to transfer the art expression into music language using a unique multisensory design approach where art is translated into music, and location is chosen co-create the experience. Recorded talks with the artist give insights into her life in art, her inspiration and her craft of expression. The gallery game genre allows access for a wide audience without the limitations of a physical exhibition venue (e.g., availability, costs for rent). In particular, we recommend it as a family experience on a walk for music and art education and a collaborative experience.
