“Sweet Castle” — A Cooperative Experience with AI Buddies

“Sweet Castle” is an immersive experience that marks Tyffon’s first implementation of AI technology. Participants interact with unique AI buddies that appear through smart glasses, engaging in conversation and collaborating with other participants to rebuild a castle made of sweets.

By combining interactive projection mapping with XR expressions via smart glasses, the experience evokes emotions represented by each AI buddy—curiosity, passion, and empathy—while delivering Tyffon’s signature finely crafted world-building and a deeply immersive experience design.
