**EchoGarden** is a markerless augmented reality mindfulness experience designed to bring a moment of calm into the user’s everyday environment.  When the app launches, users are prompted to scan their surroundings to detect a horizontal surface. Once a valid plane is found, a glowing seed automatically appears in the real world. Within seconds, the seed gently sprouts and grows into a bioluminescent AR plant anchored naturally to the detected surface.  The plant performs subtle idle animations to feel alive and immersive. Its leaves sway softly, faint particles drift upward, and ambient nature audio plays quietly in the background to create a peaceful atmosphere.  When the user taps the plant, it responds with a glowing pulse, a gentle expansion of its leaves, and a soft chime sound. This interaction reinforces presence and emotional connection without overwhelming the user with complex mechanics.
