Description

Magic cube for blind person

Technical Field

The utility model relates to a magic cube technical field especially relates to a blind person's magic cube.

Background

The magic cube, also called the Rubik cube, is called the magic cube in Taiwan, is called the twister dice in hong Kong, and has the English name: rubik's Cube. The third-order magic cube is a 6-face cube made of elastic hard plastic. The core is a shaft and consists of 26 small cubes. The device comprises 6 central squares, which are fixed and only one side has color. The corner square (corner block) has 8 (3 faces are colored) which can rotate. The edge square (prism) can rotate by 12 (2 faces are colored).

Besides the three-order magic cube, the two-order magic cube, the four-order magic cube and the seventeen-order magic cube are provided, more and more new modern inventions are provided, the models of the new inventions are different, but the new inventions are interesting. When the toy is sold, the microcubes are arranged so that each face of the macrocube has the same color. When one face of the big cube is in translational rotation, the single color of the adjacent faces is destroyed to form a new pattern cube, and then the new pattern cube is rotated and changed to form small squares with different colors on each face. It is estimated by experts that all possible pattern formations for the magic cube are about 4.3 x 10^ 19. The playing method is to restore the disordered cube to six sides with a single color as soon as possible by six-side rotation.

Six outer surfaces of the existing magic cube are generally formed by changing designs such as colors, numbers and the like, and the magic cube is suitable for people with blindness to entertain eyes and develop intelligence; for the blind, the magic cube cannot be used by visually perceiving the change of the color, and therefore, the magic cube suitable for the blind is urgently developed to provide entertainment for the blind and the like.
