Do designers of new products seriously consider ease of use? As the December buying frenzy fizzles, we are often reminded that 70% of the US economy is driven by consumer spending. We are not reminded too often about the Longevity Economy -- that 90+ million people are 50+, have most of the money, own most of the homes and cars, and thus buy the most of everything, including technology. And even the growth of social media shifts older - the fastest growing segment of Facebook users are aged 65+, Facebook has apparently saturated and/or bored teenager segments who have moved on, at least for now, to other stuff. So as some of you head off to CES exhibit halls this coming week, please consider the product user interface of what you see. Look at the TV, 'white hot' wearables, fitness devices, car tech, the ironically-titled not-so-smart phones, tablets, the health apps that apparently will eclipse the TVs. Count the demos you see of products you could characterize as simple, elegant, easy-to-use designs for all ages, including those who need to put on their reading glasses to read the manual or the 70% of adults who suffer eye strain peering at their devices.
