Using the tools of the “maker” movement, and following an iterative co-design process with Orientation and Mobility instructors, we created an innovative tool (3D printed interactive model of a train station) for teaching complex spatial knowledge. Then, we did a comparative study with end users between the 3D interactive model that we designed and two 2D interactive tactile maps representing the same location. Our results show that the 3D interactive model is useful and usable, provides better satisfaction and is preferred to 2D tactile maps. In addition, complex spatial notions are better understood with the 3D model. Altogether, these results suggest that the “maker movement” may empower special education teachers with adapted and innovative tools.}, booktitle = {Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems}, articleno = {540}, numpages = {15}, keywords = {Visual Impairment, Verticality, Spatial Knowledge, Interactive 3D Model.}, location = {, Hamburg, Germany, }, series = {CHI '23} }
