This isn’t the first time Frank Welte finds himself in front of an audience that doesn’t know how to read a map. He stands up and presses the thick 11” X 11.5 paper map across his torso on a diagonal. The right hand holds one corner steady; with the left he navigates a slice of San Francisco’s South of Market neighborhood.
“The first thing I’ll do,” he tells the assembled graphic designers, user experience experts and urban planners during a two-hour workshop, “is start at the upper left, to see what the title of the map is, find the scale and locate north.” This three-page black and white map shows the area around Market Street where Welte, who is blind, works as an accessibility media specialist at LightHouse for the Blind and Visually Impaired. Without adding a crinkle to his blue dress shirt, he speeds to the center of the map for the “you are here” cluster of dots in a circle, finds Market street and starts tracing parallel streets, using the key on the pages behind it to locate street names.
