Google Glass was launched in 2013 as a pair of thin, wireframe glasses with a chunky right arm to accommodate a camera built into the corner of the right lens.
Wearers could use the camera to take images and record their surroundings, while simultaneously interact with a digital display
The device created a lot of excitement when it first appeared at a Google event in June 2012.
But after its launch the following year, concerns about its impact on privacy, potential for abuse and questions about its style and usefulness arose – and grew until Google Google said it would stop making them in that form in 2015.
A revamped version, Google Glass Enterprise, appeared two years later but was retired in 2023.
Former BBC Technology Correspondent Rory Cellan-Jones was among those who had deemed Google’s device in its initial form to be “a failure”.
The success of so-called wearable computers, he wrote, would likely depend on having the tech to bring their potential to life and them being “both attractive to wear and so easy to use that you forget that you have them on”.
Today, tech giants have tried to make AI and smart glasses more wearable by partnering with designer eyewear brands – and can pack more power and features into smaller, sleeker frames.
But there remain concerns about privacy and usability.
