Using LEGO to model 3D tactile picture books by sighted children for blind children

Abstract

3D printing has shown great potential in creating tactile picture books for blind children to develop emergent literacy. Sighted children can be motivated to contribute to the modeling of more tactile picture books. But current 3D design tools are too difficult to use. Can sighted children model a tactile book by LEGO pieces instead? Can a LEGO be converted to a digital model that can be then printed?
