iSandbox - world's first interactive augmented reality sandbox. Combining classic children game of building sand castles and modern technology we created this innovative equipment for education and entertainment. Augmented reality allows children to learn the physical world in a fun way.A depth measurement sensor determines the distance to the sand surface. The software we’ve developed processes the data and sends instructions to the projector, which highlights the sand surface. This amazing yet simple innovation creates blue water, red lava from volcanoes, green hills and many other objects.
