The invention discloses a holographic-projection intelligent interactive device, and belongs to the field of toys. The holographic-projection intelligent interactive device includes a spherical cavity, and the spherical cavity is composed of two spirally-clamped hemispheres; a plurality of first through holes are formed in the outer surface of the spherical cavity, the spherical cavity is internally provided with a rolling cavity, and the rolling cavity is composed of two spirally-clamped hemispheres and can roll in a sphere; a plurality of second through holes are formed in the outer surfaceof the rolling cavity, the rolling cavity is internally provided with a plurality of geometric blocks, and the geometric blocks can penetrate through the first through holes and the second through holes. The holographic-projection intelligent interactive device has the advantages that the interest of children in playing can be aroused, and preliminary understanding of space and shapes can be formed in the playing process.
