This IDC study presents the five-year forecast for U.S. wearable computing devices (commonly referred to as "wearables") by product category. The U.S. wearable computing device market will reach a total of 24.3 million units in 2015. From there, the market will reach a total of 39.8 million units in 2019, resulting in a five-year CAGR of 36.5%.
Driving the market forward is increased emphasis on smart wearables, or those devices that can run third-party applications on them. Apple's Watch will inject new growth into smart wearables and, with it, bring greater attention to the market. Basic wearables, or those devices that do not run third-party applications on them, will continue their ascent, resulting from continued interest in health and fitness trackers as well as more devices and experiences coming to market.
"Wearable computing is moving into its innovation stage," says Ramon Llamas, research manager with IDC's Wearables program. "What had essentially started with simple health and fitness bracelets and bands is evolving to more sophisticated devices that augment the PC and smartphone. This leaves plenty of space for vendors, platforms, and developers to push the envelope while courting both consumers and enterprise users."
