A London-based start-up has hacked Google Glass to allow the wearer to control the smart glasses by brainwaves.
The firm, This Place, has developed software called MindRDR and combined it with an EEG headset to make it possible to take by just thinking about it.
The developers suggest that it could be used in high-pressure hands-free situations, such as during surgery.
The MindRDR software has been released for free so other developers can play around and see what other uses they can find for it. You can find out more about the software and download it here.
A Google spokeswoman has made a statement to the BBC declaring that Google does not support the app.
"We have not reviewed, nor approved, the app so it won't be available in the Glass app store,” she said.
"Of course, we are always interested in hearing about new applications of Glass and we've already seen some great research from a variety of medical fields from surgery to Parkinson's."
