CHERISH+ has a simplified version of the three-dimensional model and has voice interaction function to help children play more easily. Visually impaired children can perceive its overall shape and its general texture through touch. During this process, children gain experience in different fields through a series of interconnected activities, and feel the vastness, change, diversity, and beauty of nature. This is a sustainable educational and comprehensive learning. Experimental tests and questionnaires were conducted on visually impaired children, the time and the frequency of building blocks, the emotional fluctuation and other factors was calculated to verify the use effect and sustainable educational effect on visually impaired children. Research shows that by stimulating the senses of touch, hearing and vision. It can improve children's imagination, can enables visually impaired children to understand the world more comprehensively and safely, and promotes the improvement of children's language intelligence, limb motor intelligence, spatial intelligence, and natural intelligence.
