People have asked what is that box on the side of the walker. After this student with deafness and very low vision due to CVI gets into his walker, he travels to the cafeteria to buy yogurt. He places the dollar for yogurt into the black box. The tab to lift the box is highlighted in red shiny duct tape so he knows where to grab to lift and open. He travels the hallways and turns at the large, shiny red triangles that mark each turn. The cafeteria has distinct bank of lights so he understands when he has arrived. He greets and then thanks the cafeteria worker using a red switch. He then can travel back to class.
