Remember ergonomics? Not many people seem to.
I often see products that look like the designer has no idea of the shape and size of a typical person. They may have been designed for an average human being of the 1940s … but not thew 21st century.
Think seats on public transport, on aeroplanes, in cars. You have to squeeze yourself into an impossibly small space – especially if the next seat is already occupied.
And control systems and and ‘user interfaces’ which are too often user-hostile rather than user-friendly.
And don’t get me started on instruction manuals – translated from the original Japanese or Chinese into modern gobbledegook.
People change gradually from one size to another – or one frame of mind to another. There should be plenty of time for designers to ‘catch up’. This would involve a little more thought – but in addressing control systems, user comfort, user understanding, ease of use and so on could significantly improve productivity.
