Paul Arthur, 76, a graphic designer who pioneered the international language of pictographs — the language of vision, as he called it. He helped mastermind the PATH system of signs to guide people through the tangled skein of shopping tunnels beneath downtown Toronto, as well as signs at Toronto Zoo, including the big coloured feet painted on the ground. He coined the terms 'signage' and 'wayfinding'.

Hospitals often have labyrinthine circulation systems and confusing signage. Add to that the stress and confusion of people visiting the hospital and you have situations where people cannot find their way through buildings.
