The design of the teaching materials offered both the teachers and the handicapped children a novel learning method.
The study, therefore, used augmented reality technology as an aid to design more lively teaching materials.
The study therefore used augmented reality to provide this technical assistance and trained special education teachers to use this technology to design and produce teaching materials that better meet the needs of handicapped children.
As the picture cards are cheap and can be produced using printers, it offers a practical option for special education teachers in designing and producing teaching materials.

Introduction Auxetic materials have attracted a great interest of study in recent decades.
Different from conventional materials, auxetic materials display negative Poisson’s ratio which means they laterally expand when extended or laterally contract when compressed [1].
They are also the most commonly used structure for making auxetic materials with negative Poisson's ratio.
