A new report from IDC shows that wearable technology is set for huge growth over the next four years. This year, tech companies will ship nearly 46 million wearable devices -- a 133% year-over-year increase -- and by 2019 that number will spike to 126 million.
While new types of wearables will emerge, like clothing and earwear, wrist-worn devices will continue to dominate. IDC says the Apple (AAPL 0.56%) Watch, Motorola's Moto 360, and Samsung's Gear watches will drive growth for smart wearables, but simpler devices will still be a big part of the market four years from now.
