Projection sand pool

Projection sand pool is an interactive entertainment facility that combines
physical sand pool with projection technology. It consists of environmentally
friendly and safe sand pool containers, specially designed sensing sand
particles, high-definition projectors, and interactive sensing systems. When
children stack and excavate sand piles in the sandpit, the sensing system will
capture the real-time changes in the shape of the sand pile. The projector will
project corresponding virtual scenes such as mountains, flowing water, and ocean
islands onto the sandpit, and each change in the sand pile will trigger dynamic
updates of the scene. The sand particles are made of non-toxic and harmless
materials, with a delicate touch that is safe and child friendly.
