Richard Duncan reminds us of design features that we never think of as having a specific design label such as “accessible”. For example, how would supermarket shoppers manage without automatic doors? These doors are everywhere and we don’t think twice about it. But more to the point, we probably do notice any door that doesn’t open automatically when our hands are full or we are pushing a trolley or stroller. That’s when universal design becomes visible – when it’s not there. When it comes to doors, the worst offenders are revolving doors and that is why many building codes require a separate door for people who cannot navigate the revolving contraption. Other devices we don’t think about are beeping noises at traffic lights. As more people have their heads down looking at their phones, this device designed for people who are blind has become good for many more. Lever handles and taps are now the norm because they are useable by everyone and probably more hygienic. Video captioning has also become a favourite for everyone watching social media on smart phones. Richard Duncan’s article, Hidden Universal Design: Commercial doors, is on his Linked In page.
