Glass is now overseen by Ivy Ross, a jewellery designer who runs Google's smart-eyewear division and Tony Fadell, a former Apple product executive.

"Early Glass efforts have broken ground and allowed us to learn what's important to consumers and enterprises alike," Fadell said in a statement.

"I am excited to be working with Ivy to provide direction and support as she leads the team and we work together to integrate those learnings into future products," the statement read.

The report quotes an adviser to Fadell as saying: "There will be no public experimentation. Tony is a product guy and he's not going to release something until it's perfect."

Google Glass was unveiled as a prototype in 2012. It was distributed to a select group of people as part of Explorer programme who paid $1,500 to be early adopters.

On January 19 this year, Google quietly suspended selling Google Glass to consumers while continuing to support Glass as an enterprise product.
