Global retail revenue from smart wearable devices will treble by 2016 and reach $53.2 billion (€41 billion) by 2019 compared to $4.5 billion expected this year, according to latest research from Juniper Research. The company said the market will be driven by an increase in sales of premium smart watches and smart glasses over the next five years. The recent entry of key industry players within the wearables sector has helped fuel an explosion of new devices in this increasingly crowded market. However, Juniper Research argues that vendors still need to get over the 'technology first' attitude and think in terms of consumer benefits for an increased product adoption. The company also expects smart watches to replace fitness wearables as the most purchased wearables category by 2017. Release
