Intel and Google are simply two of the technology giants to have tried and failed to take the idea of smart glasses into the mainstream.

They previously deserted its Vaunt smart glasses earlier this year after massive investment in R&D and acquisitions, whereas Google’s foray into what was anticipated to be a thriving shopper sector has pivoted to a niche product for industrial purposes.

Social media platform SnapChat also had limited success with its smart glasses.

The problem for any firm seeking to achieve traction within the AR wearables space is huge. A product that works isn’t enough.

Real usefulness will likely be essential, together with safety, discretion, comfort, and respect for others’ privacy and security, for example. Plus, the sensible pros need to outweigh the inevitable drawback of looking like a ‘glasshole.’

Facebook’s Fiscus Kirkpatrick says the company can also be working on an AR headset.

They are doing a variety of research, yet they have no product to announce now. However, they have a variety of very talented people doing the compelling, cutting-edge analysis that they hope will play a role in the future of headsets.

Facebook’s plans for AR hardware are in the early levels. However, there’s no doubting the significance that successful product launch in this area could be possible. In spite of everything, Facebook has always been reliant on the hardware of its rivals.

For instance, Apple, Google, and Samsung dominate the smartphone market, and Apple may yet be the company to popularise AR technology.

But the road to the AR-enabled future appears rocky for Facebook. Brendan Iribe, a co-founding father of Facebook-owned VR hardware maker Oculus, announced his intention to leave the company in October.

The choice has been linked to internal shake-ups and the cancellation of Oculus’ Rift 2 VR headset, amid claims that Facebook execs and the Oculus leadership have differing opinions on the path the VR company needs to take.
