Not for a long while. But Vancouver has struck the first blow: In September the city added amendments to its building code that, among other things, require all new housing projects to use levers for doors and faucets. (The regulations go into effect in March 2014.)
It’s a small, but significant, advancement in the growth of Universal Design. First developed in the 1970s, UD — also known as “Design for All” or “Inclusive Design” — is a process and philosophy for making “products, environments and systems function better for a wider range of people.”
In the case of levers vs. knobs, studies have shown that levers work better for, and are preferred by, the elderly and those with arthritis, as Popular Science points out.
Of course, when humans finally reach “the future” — at least according to science fiction — we’ll dispense with knobs and levers altogether in favor of a better, whooshier technology.
