One of the more promising markets for wearable tech is the cohort of aging baby boomers, now edging into retirement age. Here’s a very good post suggesting that gadget makers are on the cusp of doing stupid things that will alientate those potential buyers.
Essentially, author Suzie Mitchell says that product designers need to remember the user interface. Keep it simple; build it so that training needs are minimal-to-non-existent; make buttons, targets, and type big enough to use and read; and make sure to articulate why a boomer would want the thing in the first place.
Good advice.
