Credit Suisse estimates that the wearable technology market will grow from $3 to $5 billion, where it is today, to $30 to $50 billion over the next three to five years.  Within retail and apparel, “wearables,” consisting of accessories with embedded sensors and displays, are already commonplace from sports brands (think Nike’s FuelBand).  As another example, Adidas revealed a digital technology-enabled sneaker, being developed in conjunction with Google Glass, at this year’s South by Southwest.
