Smart glasses and wearable tech to be worth $1.5bn by 2014

And while the $1,500 device won't hit the consumer market until 2014,

Presumably, that's why Juniper predicts the next-generation wearable devices market – like smart glasses – will be worth more than $1.5 billion by 2014, rising from $800m in 2012.

The bulk of revs are set to come from consumers who spend on mobile fitness and healthcare accessories, while the impact of 'head-mounted displays' will increase over time.

Nitin Bhas, report author, Juniper, said: "With consumers embracing new technologies and form factors, wearable devices ranging from fitness accessories to heads-up displays will be more prevalent in the consumer market.

"While fitness and entertainment will have the greatest demand from consumers, within an enterprise environment, the demand for wearable devices will be greatest from the aviation and warehouse sectors."

North America and Western Europe will hold 60 per cent of device sales, while healthcare will amount to more retail value than fitness devices, despite the latter selling more units.
