Sphaera Somnium is a 360 degree audiovisual installation that serves as a gateway for individuals to step into a realm filled with speculative spaces, where immersive techniques encourage the human senses to explore uncharted territories. Within Sphaera Somnium, we aim to demonstrate how new spatial media can enrich user experiences and offer glimpses into alternate perspectives. By seamlessly blending audio and visuals, this immersive journey is meant to evoke dreamlike, multi-sensory sensations. The project also offers accessibility to realities that would typically require significant time, expense, and transportation to access. This accessibility not only breaks down physical barriers but also levels the playing field on the cost of experience, making it available to a wider audience regardless of geographical location or financial means. By providing a platform for individuals to engage with these speculative environments, we hope to foster a deeper understanding of our relationship with technology, perception, and the world around us. As participants are transported into these immersive realms, they are encouraged to contemplate the emerging uses of new technologies and how they shape our understanding of reality.
