Balu Huang, chairman of the Cultural and Educational Foundation for the Blind, says that the tiles are only needed at intersections and other places where a choice must be made. They are not necessary where the path is straight. Currently, however, all of these tiles are laid on straight paths, with some even having been placed next to trees and telephone poles.
愛盲文教基金會總幹事黃建忠指出，路口或者是需要做選擇的地方，才需要導盲磚，直線其實不需要，但現在所有導盲磚都在直線上鋪，有的甚至鋪在大樹邊、電線桿旁。
