Developed by London-based start-up "This Place", the open source "MindRDR" app combines wearable tech with another headset with sensor.
It analyses the user's brainwaves and gauge the user's level of focus.
Concentrate hard until a horizontal white line starts to rise on Google Glass "screen".
When the level crosses a certain threshold, MindRDR tells Google Glass to take a picture.
Stay focus and Glass will post the photo on social media.
"It's pretty cool when you have taken a picture and shared it, just by thinking," said Chloe Kirton, creative director of This Place.
The technology could also be used to help those with severe physical disabilities such as locked-in syndrome or severe multiple sclerosis.
The new app is yet to be approved by Google Glass team, reports added.
